Introduction

The post-harvest and marketing system comprised of a series of interconnected activities which starts after the harvesting process and continues until the distribution of food products to the consumers. An effective post-harvest system makes sure that the food product reaches the customer in a short time without sacrificing volume, quality, and safety of the food product (Gardas et al., 2018). Increasing population growth in the last few centuries and the requirements from industrialization forces the need for sustainable food production and better food processing technologies. There is a requirement of balance between sustainable food production practices, a healthy environment, and a healthy population due to the rapid changes in the climate and population. According to the Food and Agricultural Organization (FAO), there will be a requirement of a 70% increase in food production in 2050 due to the growing population across the world (FAO, 2017).

The challenges such as improper land use, decrease in biodiversity, aquatic eutrophication by over-fertilization, global warming, water shortages due to improper irrigation etc. imposed awareness among the stakeholders to bring more efficient approaches in agricultural and food production practices. This brings the idea of terms such as recyclable and eco-friendly packaging, buy local, whole foods, free-from, and fair-trade (Boye and Arcand, 2013). Recent trends in climate and changes in the environment may pose challenges to achieve the required food production in the future. In addition to the steps taken for increasing food production, the steps to reduce food loss are important. In 2011, it was calculated that 11.3 billion tonnes of food was wasted in a year, which is almost one- third of the total food production (FAO, 2011).

Introduction

Animal husbandry has been an integral component of Indian agriculture since time immemorial. It is still continuing as one of the major avocations in India contributing nearly 4.9% to the national GDP and 28.4% of the agricultural GDP. Livestock population in the country as per Livestock Census 2019 is 535.78 million which is an increase of 4.6% over Livestock Census 2012 (BAHS, 2019; DAHD, 2019). Cattle, buffaloes, sheep and goats are the major livestock in the country. Today, India is the global leader in milk and milk products with a production of 187.7 million tonnes (MT) and the availability of 394 ml milk per capita per day. The per capita availability of milk has increased substantially during last four decades. The anticipated milk demand is expected to be 266.5 MT by 2030 based on per capita consumption of 468 ml/day (Table 1). It has been made possible with the active involvement of farming community and by creating awareness about high yielding breeds of livestock, improved rearing methods and milking, management of pests and diseases and most importantly, the feeding of the animal. The crop residue constitutes a major chunk of fodder to the livestock in many parts of the country. However due to their low nutritive values and poor palatability, it is not helping to realize the full milking potential of animals. A huge opportunity exists in livestock sector as there is a growing demand for animal products particularly milk and meat (NDDB, 2019). In addition, for promoting organic farming particularly the need of farm yard manure has necessitated the farming community to keep livestock as a complementary component of his farming. It provides draught power and organic manure to crop sector and hides, skin, bones, blood and fibers to the industrial sector. Therefore, the importance of livestock goes beyond its food production function, and has become even more significant (Birthal et al., 2002).

Introduction

The Indian fisheries sector is set in a unique and diverse set of resources ranging from the pristine waters of the Himalayas to the sprawling Indian Ocean. The fisheries biodiversity of the country encompasses a wide spectrum of physical and biological components that support the livelihoods of millions of people. Fisheries resources are set in different ecosystems. With growing population and the increasing demand for fish protein, the need for sustainable development of aquatic resources is now felt much more than ever before.

Fisheries and aquaculture remain important sources of food, nutrition, income and livelihoods for hundreds of millions of people around the world. Global capture and culture fish production during 2019 were 97 and 82 million tonnes, respectively with India being second largest producer of fish in the world after China. From 0.75 million tonnes in 1950-51, total fish production of India touched 12.59 million tonnes in 2018-19 with a contribution of 8.90 million tonnes (70.60%) from inland sector. The sunrise fisheries sector contributes about 0.96 % to National Gross Value Added (GVA) and 5.37% to agricultural GVA (2018-19) while engaging over 14.5 million people (2003 census) at the primary level and almost twice the number along the value chain. During 2018-19 the export of marine products that includes production from aquaculture reached 13,77,244 tonnes valued at INR 46589 crore (US $ 6.93 billion). The inland sector grew at a compounded annual growth rate (CAGR) of nearly 6.5% between 1979 and 2018, while overall fish production witnessed 4.5% growth, which is double the growth rate of food grains production in India.

Introduction

India is predominantly an agricultural economy and about half of the workforce is engaged in agriculture sector. Around 48 per cent of households in the country are agricultural household and they derive the monthly income from crop cultivation. India is leading in production of many agricultural crops but finding a market for marketed surplus and getting fair prices have always been a major challenge. Long time ago, traditional market system was existed in India. Marketing implied greater magnitude as yields and production started rising after farmers embraced with advanced technologies such as high-yielding varieties, fertilizers, chemical inputs, block chain development, farmers business network, market linkages, diversification towards high value crops, integrated farming system approach, precision farming including digital agriculture, drones, GIS technology, remote sensing, soil health management, crop and livestock insurance, mobile apps, web portal, machine learning and many mores. These catered the need of efficient regulated marketing system to support the farmers and keep away from them getting manipulated in the market.

India has gained self-sufficiency in the agriculture production. There is need to translate this production into better remuneration for the farming community by focusing into agricultural marketing system. The agricultural marketing system is characterized by various short comings like heavy sale of commodities at primary level immediately after the harvesting period, absence of on-farm grading of produce, poor packaging, insufficient marketing infrastructure, long marketing channels, existence of various malpractices in the marketing of agri-produce, nontransparent price discovery mechanism, lack of market information system, low marketable surplus especially of small and marginal farmers, etc.

Rising population and increasing demand for food are prominent factors driving the digital farming market. Moreover, the growing demand to efficiently deal with pests, weeds, and other diseases is encouraging farmers to digitize their farm. In developing regions, cheaper internet data and strong penetration of smart devices (especially smartphones) are driving the digital farming market. Active participation of governments in digitizing farms through investment is also driving the digital farm market.

Introduction

The food production in India has been on a rising trajectory and the country is among the top producers of several crops. It is the highest producer of milk and second highest producer of fruits and vegetables. Total food grain production in the country is estimated at record 291.95 million tonnes (MT; Second Advance Estimates for 2019-20) which is 6.74 MT higher over 2018-19. While enhanced field productivity is an essential component of agricultural sector, improved postharvest handling, marketing and processing is equally essential to reduce the waste, particularly in a country where such losses are substantial and add stress on limited farming resources, appropriate agrilogistic is needed. Post-production management and marketing infrastructure is therefore, not only vital but a priority. Such infrastructure and the services they provide are essential not only for the efficient performance of various marketing functions, but also for effective expansion of the size of markets which allows for growth.An efficient post-harvest logistics network not only ensures that produce will reach destination markets in quality and quantity, but should also trigger a steady reverse flow of market information to the source.

Introduction

Agricultural Extension is as ancient as agriculture itself. When it moves in agricultural trends, the importance on extension has also been transformed. Firstly, agricultural extension was the component of the research-extension-farmer approach. In the Training and Visit (T&V) period, communication of innovation was the crucial concept and the role of extension was to successfully disseminate the technological interventions. However, after the green revolution, the gap between resource rich and resource poor farmers widened with information and extension reaching only a few of them. With the conceptualization of new models, like Agricultural Knowledge and Information Systems (AKIS), the focus of extension has changed to formation of groups and collective farming. In time, the private sector has also entered into the agricultural arena, introducing the concept of pluralism in extension. Emphasis on mass media has also increased. More recently, Agricultural Innovation Systems (AIS) is introduced within the innovation systems framework. It focuses on the actors, their interactions, the institutions, and the policy environment to support or hinder it. Communication for innovation is the key AIS concept tried to identify the actors in systems, their core activities and bring them into an innovation platform for effective service and successful innovations (Saravanan, 2017).

Historical Perspective of Agricultural Education Policy in India

Pre-Independence Era

During the reign of the British Crown, vocational education and training suffered a great setback and there was a lack of emphasis on agricultural education, even though the Indian economy, to a great extent, depended on agriculture. In 1901, only five institutions were imparting theoretical and practical instruction in agriculture, but that education was not used in extension or fieldwork—it served only as an opening for government white-collar jobs (Crane, 1965).

Post-Independence Era

Prior to the establishment of agricultural universities, university-level education in agriculture, animal science, horticulture, agricultural engineering, and allied subjects were largely conducted by colleges affiliated with general universities that had no special commitment to the farming community. The University Education Commission of 1947, among other things, examined the state of agricultural education in India. The report of this Commission emphasized the need for having what was termed “Rural Universities.” In 1954, the First Joint Indo-American Team on Agricultural Research and Education fully endorsed the recommendations of the University Education Commission and strongly recommended the immediate establishment of agricultural universities in a few selected states. The U.S. agricultural advisors who began to arrive in India in the early 1950s were products of the land-grant university system, and many of them naturally believed India could benefit by creating a similar system (Goldsmith, 1988). The Government of India accepted this recommendation and the first agricultural university in Uttar Pradesh now named as Govind Ballab Pant of Agriculture & Technology was established in 1960, patterned on the land-grant university model of the United States. This was a significant turning point in the history of agricultural education in India. The Second Joint Indo-American Commission (1959) reiterated the recommendations of the First and recommended that at least one agricultural university be established in each state. Agricultural universities have now been established in 21 of the 28 states and the concept of the agricultural university now forms an essential part of the national policy on education.

Introduction

India is considered as one of the emerging superpowers of the world. This potential is attributed to several indicators, the primary one being its demographic trends and a rapidly expanding economy. In 2015, India became the world’s fastest growing economy with a 7.5% estimated GDP rate. But in the year 2020, the pandemic lockdown situation created adverse impact on the global economy. At this juncture, there is an urgent need to focus on native and indigenous resource mapping and judicious utilization of it to be a self-reliant. The COVID-19 pandemic has necessitated a new set of reforms to strengthen the economy. The first mention of this came in the form of the ‘Atmanirbhar Bharat Abhiyan’ or ‘Self-Reliant India Mission’ by the Government of India during the announcement of the coronavirus pandemic related economic package on 12^th May 2020. Almost 70% of India’s population depends directly and indirectly on agriculture for their survival. This means the country cannot have a development model that ignores agriculture.

It’s time to take a look at India’s agriculture economy. Over the last 10 years, (2008-19) India has been a net exporter of many farm produce. In fact, in 2018, the government has come up with a new agricultural export policy aimed at doubling farm income by 2022. However, in 2019-20, agri-exports were just $36 billion and the agri-trade surplus was $11.2 billion. The net agri-trade surplus has been falling over a period of time, making it difficult to achieve doubling of farmers’ income and doubling of agriculture exports by 2022as well.

India is not yet self-reliant in various essential agriculture commodities and depends heavily on imports. India imports around 15 million tonnes of edible oil every year — more than 9 million tonnes of palm oil and about 2.5 million tonnes each of soybean oil and sunflower oil. It buys palm oil from Indonesia and Malaysia, and soy and sunflower oil from Argentina, Brazil, Ukraine and Russia. There is a need to create self-reliance in theses commodities enhancing productivity of Indian farms to create competitive advantage for domestic producers. India can step up cultivation of sunflower, groundnuts, mustard and oil palms. Presently, India has about two million hectares of land that is suitable for oil palm cultivation.

Introduction

India is transforming from the phase of revolution to commercial mode of agriculture, a step ahead of self-sufficiency. It further evolves to reach a goal of self-reliant on agriculture and allied sector. The present phase demands several technological innovations, their application and implementation in the market. Meanwhile this phase needs due attention for handling the issues on conservation of natural resources, especially germplasm resource, biodiversity conservation, socio-cultural-economic values of our country, etc. The whole process requires good investment on research and development, various economic measures and implementation. It is only possible with vibrant governance and policy implementation of a Government. Already Government of India has taken several measures to transform agriculture. Recent analysis showed that Indian agriculture is the silent ever green revolution. Food production is kept pace with the growing population since independence. Further, it needs several innovations on technologies coupled with policy support to fill the demand. India is placed 49^th position in the world on innovations. Analysis suggested the huge potential for innovation due to its huge human capital, which perhaps need for the country like India to meet the food demand of 333 million tonnes by the year 2050. These innovations must be focussed for growth to efficiency, employment generation, food security to nutrition and health, shortage management to surplus management, input intensive to knowledge intensive agriculture, climate change and sustainability, production and producers, policy interventions, regulations and reforms. The Government emphasize usage of e-trading platforms to sell the farmers’ produce of their choice rather using mandis. This will enable contract farming and inter-state trade. However, major innovations and investment must be implemented on transportation, logistics, and digital access and payments to enable widespread prosperity. Thus, focus must be on the complete agricultural value chain. In fact, focus needed on value addition, rural infrastructure, logistics, warehousing, and quality certification of agriculture produce. India has greatest challenges to face in the future for food and nutritional security, adaptation and mitigation to climate change and sustainable use of essential and scared resources like water, land and energy.

Agriculture is the science and art of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization. The history of agriculture began thousands of years ago. After gathering wild grains began 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Pigs, sheep and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. This chapter discusses about the agriculture and robotics in agricultural field.

1.1 Introduction to Agriculture

The word agriculture is derived from a Latin word- “agri” means soil, and “culture” means cultivation of the soil. In modern terms, agriculture comprises “the art and science of cultivating the soil, growing crops and rearing livestock.”

Farming is a complete system which includes inputs, processing, and outputs. The inputs are seeds, fertilizers, machinery, which undergoes operations like ploughing, sowing, irrigation, weeding, and harvesting. The final outputs are like crops, dairy and poultry products.

The Internet of things connects the devices over Internet. The devices can communicate with each other and can be monitored and controlled remotely. The IoT is a system with interrelated computing devices, digital and mechanical machines, objects, animals or people each with an unique identifiers (UIDs ). It has the ability to transfer data over a network without human intervention. The Internet of Things is simply a network with Internet connecting the objects to collect and exchange the data. This chapter covers the basics of Internet of Things and its components.

2.1 Characteristics of IoT

Internet of Things can be used to design products for businesses. The added value to the businesses over IoT is created by the information which is collected by connected devices. The process has five phases of lifecycle, first phase is ‘create phase’, where sensors collects the data from environment. This data can generate the information. Second is ‘communicate phase’ where data generated in first phase is communicated to the required destination. Third is ‘aggregate phase’ where collected data over network is aggregated by device itself. Fourth is ‘analyse phase’ where aggregated data is used to generate patterns and use it to control and optimize the process. Fifth is ‘act phase’ where actions are taken on the basis of information extracted from the aggregated data.

The characteristics of IoT may vary from one domain to other. Few characteristics are listed as follows-

This chapter describes the components to design the mobile platform. The UN estimates the world population will rise from 7.3 billion today to 9.7 billion in 2050. The world will need a lot more food, and farmers will face serious pressure to keep up with demand. Agricultural robots can be used to increase the production yields for farmers in various ways.

3.1 Role of Robots in Agriculture

A challenging problem in Mechanical Engineering and robotics is the design of a mobile robot. The robot must successfully traverse through its environment, including rough terrain, grass, hills, etc. For correct positioning of the robot, the wheels of the robot must have good traction and never lose contact with the ground. For improved manoeuvrability the robot must also be able to rotate around a centre point as close to its centre of mass as possible. All of these factors have been considered in the design of a second generation outdoor de- mining robot.

A rectangular frame for the robot allows the easier positioning and accessibility of parts within the robot, which is useful in the development phase. Having the wheels up front helps the robot drive onto a slope. A circular frame for the robot would allow the robot to rotate around its true centre, such a frame, with the wheel axle running along the diameter of the frame would need support at the front and back of the robot.

Sensor is a device which converts environmental parameters into electrical signals. In the broad definition, it is a device, module, machine, or subsystem which is designed to detect events or changes in the environment and send the information to other electronics components. An actuator is a component of a machine which is responsible for moving and controlling a system. A microcontroller is a small computer on a single metal-oxide-semiconductor (MOS) integrated circuit (IC) chip. This chapter explains the microcontroller development boards and their components along with the classifications of sensors and actuators.

4.1 Classification of Sensors

The sensors can be classified on the basis of different areas as follows-

i. Classification based on Application

Sensors are chosen on the basis of application where they need to be implemented like Industrial process control, measurement and automation, Automobiles, Consumer electronics, Aircraft, Medical products etc. As with change in application the selection criteria changes, so application needs to be considered.

The communication module is a device which is used to control the communication between the stations. This chapter explores the different communication modules and their specifications.

5.1 WiFi

ESP8266 WiFi Module is a WiFi serial transceiver module. This chip has a full TCP/IP protocol stack with the computational power onboard. This makes the board simple to use as Wi-Fi connection board. The specification of this board includes, 32-pin QFN package, Integrated RF switch, Integrated RISC processor. It has on-chip memory with external memory interfaces, integrated MAC/baseband processors, Quality of Service management, on chip regulator, Integrated WEP, TKIP, AES, and WAPI engines, 11 b/g/n. It has integrated TCP/IP protocol stack and Integrated PLLs, regulators, DCXO and power management units. It has +19.5dBm output power in 802.11b mode and Power down leakage current of <10uA

5.2 Bluetooth

Bluetooth is a wireless protocol. The recent introduction of Bluetooth with Low Energy extension is also as iBeacon. The advantage of BLE4.0 standard includes the low power consumption, which makes it a better option to be used in smart phones. This facilitates the setup of a mesh network of Bluetooth devices, with lower latency and higher range respect to standard Bluetooth.

This is a SMD BLE module based on TI cc2541 chip. It has low cost, small and easy to use. The preloaded firmware allows to build BLE communications with AT command. It supports communication with iPhone, iPad (iOS 5.0 or greater) and Android 4.3 or greater. It works on frequency: 2.4 GHz ISM band and modulation method is GFSK (Gaussian Frequency Shift Keying). It has transmission power: - DBM, 23-6 DBM, 0 DBM, 6 DBM, can be modified by the AT command. It works on baud rate 9600bps. It can operate on temperature range -40 ~ 125°C.

Another interesting board is the HC-05 Bluetooth module. Specifications of the works Master/Slave configurations. It operates on frequency of 2.4GHz ISM band with Modulation GFSK(Gaussian Frequency Shift Keying).

Robots can replace human efforts in the future. Discovery of robots in agriculture is going to accelerate the growth of agriculture 4.0. Nursery planting needs robust and profitable solutions. Nursery plants deals with the direct consumer, which is the primary stage of agriculture. An intensive care is required to look after the nursery plant before going to be planted. Now a days robots are used to monitor the plants, essentially to maintain the health standard of a plant. This chapter illustrate the applications of the robots in nursery planting.

6.1 Introduction

Nursery is the primary stage where seeds are grown in to the young plants. Nursery planting involves many activities like seeding, potting and monitoring. The process required high attention to look after at this stage [1]. As the food demand is increasing day by day, it is necessary to adapt unconventional way of farming. Bringing robots in to the farming will bring a lot of changes in the traditional agriculture. The robotics in agriculture is not new, it has started with evolution of autonomous vehicles [2]. The usage of robots are increasing exponentially. So the researcher and scientist also started use of robots in agriculture. They found a phenomenal result in term of easy to handle the agro tasks, seeding, weeding, automatic irrigation and harvesting. It draws the farmer attention down the line [3].

Agriculture is the backbone of India. Evolution in technology is bringing new dimensions of conventional agriculture. Looking towards the current food demands it is very crucial to maintain the food supply. According to UN (United Nations), by 2050 the world population will be increased to around 9.3 billion which increases the food need. As the technology in agriculture evolving it seems that we could be able transform conventional farming to unconventional and traditional to modernization by the help of agriculture robots. Agri-bots can be autonomous with human intervention that could perform the task precisely. Chapter illustrates the applications in agriculture seeding. These robots are efficiently used in crop seeding.

7.1 Introduction

The very first agriculture robots were used in the early 1920s along with autonomous vehicle development.

Agro robots are becoming an ongoing pattern in farming with lots of research advancement and business models [1]. Agrarian robots have huge focal points as far as adaptability, flexibility and ecological advantages contrasted with customary horticultural apparatus and speak to an extraordinary resource for cutting edge precision agribusiness. Numerous advances in machine vision with imaging and otherworldly cam-periods for distinguishing weeds, vermin and infections, supplement inadequacies in soil or plant leaves have given profound applications to be mounted on independent vehicles for exploring soil and crops and for additional downstream choice help and control [2]. The mechanical network has additionally made earth shattering upgrades and advancements as far as utilizing a far reaching working framework, the Robotic Operating System (ROS), just as applying strong stages and route calculations.

Comparable to horticultural robots, the attributes of the central framework of robots are the lightweight, little size and lively self-governance [3]. Lightweight implies that the vehicle requires lower impetus vitality and incites less soil compaction while simultaneously the vehicle must be little for security reasons, for accomplishing more noteworthy accuracy during execution of assignments and having more maneuverability inside the field to limit turning delays.

Precision Agriculture is fulfilled by adapting suitable monitoring and analysis mechanisms. Autonomous monitoring is getting a new dimension using robots. Agriculture is the trending area to attract new professionals, investors and new companies. The technology in agriculture is not only increasing the yields but the time and labour. This chapter illustrates the use of robotics in crop monitoring and analysis.

8.1 Introduction

Monitoring of agriculture farm enhance the productivity. Evolution in technologies in the era of agriculture brought a lot of innovations. Among these innovations robots are one of them to be implemented in agriculture to enhance profitability and reliability with minimum human resource. At the same robots were deployed to monitor the farming land from weeds and try to remove these. Due to which uses of agrochemicals reduced down the time line. When precision farming came in to the pictures robots are the best use cases. In fig. 8.1 autonomous mechanical robots are shown, which are used to remove the weed from farming land. Robots are equipped with sensor modules, actuators and IoT enabled which makes the things very easy to control from remote area with commands.

Agriculture irrigation is a crucial part of precision farming. An irrigation system required a lot concentration to grow the plant healthy. A smart irrigation system in an agriculture farm leads to maximum profits in terms of yield. Integrating technologies like IoT (Internet of Things), AI (Artificial Intelligence) in irrigation accomplish to the human efforts. Controlling of water pumps, sprinklers seamlessly draws the kind attention of farmer to adapt these technologies in their day today farming schedules. This chapter illustrates a wide variety of robots used in irrigation to achieve maximum yield and minimizing water loss. The high scalability and reliabilities of these autonomous robots replicates the potential of agriculture 4.0 in coming future. Advanced robots deployed on the field to monitor the land and pass the information to the controllers and further to the water pumps. Here case study of robots is highlighted to reduce water losses by using nozzles mechanisms.

9.1 Introduction

Agriculture faces many environmental challenges. As far as the irrigation in agriculture is concerned it is very essential to maintain soil hydrated and water level in the field. Robotic irrigation enables autonomous irrigation from remote access [3]. Smart irrigation technique enables a lot of water saving. So robotic in agriculture plays a very crucial role in it [2]. In order to avoid water losses agro robots adapt smart irrigation techniques like droplet irrigation and sprinkling. To maintain sustainability, water resource management is required. Technologies like drones, smart sprinkler based on IoT, smart droplet irrigation used across the globe. These technologies have the greatest impact on productivity and sustainability of the environment as well. As far as the country India is concerned, due to diversity in geographical infrastructures rainfall changes from state to states. So, a wide range of water diversity is found to grow agricultural foods. For example northeast and southern part of India due to heavy rainfall paddy cultivation is preferred since it requires a lot of water. Whereas the northern part of India observe a moderate rainfall, so vegetables and other agriculture foods get cultivated. At the same there are certain states like Rajsthan, Gujrat where very less rainfall occurs through varieties of crops related to dal.

Weed control in agriculture disturbs the farming. Weed management and control essentially increase productivity of the farm. Autonomous robots for weed control systems are gaining a lot of attention. Adaptability of effective weed control robots has the potential to bring evolution in the areas of weed species, genetics and climate conditions. Weed control is one of the major challenges in agriculture. Removal of weeds from farming land required a lot of human effort. To minimize the weed growth pesticides and chemicals are used which is very harmful. In order to make this process easy and reliable robots are used nowadays. Robots are specially designed to detect the weeds and remove them within a stipulated time period. Robots are programmed using various algorithms to do this task in an efficient way without human efforts. This chapter illustrates the use of modern robots in weed control to help the farmers to gain maximum profit and healthy concerns without using chemicals to do so.

10.1 Introduction

Over the time, weed control in a farming land has been an issue. Evolution in technologies in the area of agriculture brought a lot of innovations. Among these robots are one of the innovations to be implemented in agriculture to enhance profitability and reliability with minimum human resource. The robots are deployed to monitor the farming land from weeds and try to remove these. Due to which uses of agrochemicals reduced down the timeline. When precision farming came into the picture robots are the best use cases. An autonomous mechanical robot was used to remove the weed from farming land. Robots are equipped with sensor modules, actuators and IoT enabled which makes the things very easy to control from remote area with commands [4].

In the wild (forests) plants grow by their own, but in agriculture because of limited space they don’t have freedom to grow in a much natural way. This can lead to structural irregularities in their growth, and can hamper the overall plant’s development and this will impact the produce or crop yield. To deal with such constraints and to boost the crop production, the methods of thinning and pruning provide efficient ways to train the growth of young plants and maintain the health of grown-up plants.

11.1 Introduction

In agriculture, thinning means the removal of some plants or some parts of plants that show inconsistent growth and or are damaged by some pest or disease, without removing the whole tree or plant. The selective removal of branches, buds or roots is termed as pruning [1]. If the plants are overcrowded in a confined space, the overall health of the crop decreases due to the competitive stress from the neighbouring plants. Thinning and pruning is done to improve the growth rate or health of the plants by decreasing the competitive stress. Thinning and pruning in agriculture is the sensible removal of plant parts such as flowers, shoots, its branches or other parts to correct or maintain that structure of the tree and control be directed growth of the crop. This practice covers the precise removal of the unhealthy and obstructive part of the plant branch, leaves, fruits, buds, fruits, etc. Pruning improves the quality and longevity of the crop, leading to quality produce and increased yield of the field. This also helps in increasing the size of the fruit as it increases the availability of nitrogen required for growing and stimulating growth of the crop. There are several factors that influence the amount of pruning to be done, i.e., age of the plant, condition of the bark and wood, growth characteristics, whether cup crop/plantation is permanent or seasonal [2]. Pruning is done for controlling the size of the plant, controlling the structure makeup of the plant, controlling and improving the light distribution of the plants by the selective removal of leaves to improve the quality of the fruits, removing the diseased parts of the plant and to regulate the fruit crop and increase the life of the tree.

The principle behind thinning and pruning is to admit more sunlight to the branches that bear fruit by the selective removal of the unproductive branches which obstruct the sunlight to fall on the productive branches to increase the productivity white and vitality of the plant to obtain optimum healed of good quality crop [3]. Young trees are pruned so that they acquire the desired shape. In old trees it is done to stimulate flowering. In plants bearing fruits or crops, pruning is done to allow adequate sunlight to fall on fruit bearing branches, so that quality crop is produced. Very old plants heavy pruning is done to restore the vigour of the plant. It is also done so that the loss of nutrients being shared by the diseased peak or shading branches is reduced. The use of robotics and other automated systems can aid in the precise pruning and thinning of the crop. This will also automate the whole process and will save their requirement on the extensive manpower which ultimately saves time.

To cater the increased demand of food, it will be required that farmers are equipped with tools and methods to improve their yields and make informed decisions [1]. Also, with the increase in population, the agricultural land is decreasing by 1 lakh hectares per year and it is required to double the agricultural produce in the next 30 years to sustain the global food requirements.

The improvements in various technological fields like machine learning, navigation, robotics etc. and their applications in agriculture is required to meet this increasing need. One of the factors is to make the farmland ready for sowing the crops, spraying, etc. and this has to be done in a precise and faster manner to address the latter issues. So, the uses of autonomous tractors for such jobs offer accurate, precise and timely preparation of the fields for the cultivation.

12.1 Introduction

Autonomous tractors or driverless tractors are unmanned ground vehicles mainly employed in agriculture for various purpose like preparation of land for the crops, harvesting, spraying, and other agricultural purposes. They are equipped with GPS, autopilot, cameras, lasers (LiDAR), and other wireless technologies navigation and mutual coordination and offer saving of both the manpower and time. These autonomous tractors can be programmed to navigate their paths through the fields and are designed to avoid the obstacles while doing their jobs. These tractors automate various laborious field jobs and also minimize human intervention in the process.

These autonomous machines are regarded to revolutionize the agriculture industry and offer safety, sharing of resources, economical solutions per square area of land, etc. Several industries like Jhon Dheere, AgraBots, EcoRobotix, RowBot, etc.

Harvesting is one of the most labour intensive jobs in agriculture, and by implying the robotics in harvesting, the quantity of the harvested yield can be readily increased, thus saving a lot of time and human resources. This also aids in reducing the farm to market transportation times. The use of robotics can also reduce the seasonal requirement of the manual labour and thus reduce the recurring costs.

13.1 Introduction

The incorporation of robotics in agriculture has proved to be advantages for the farmers and thus for the economy. The automation of various agricultural processes led to the reduction of the operational costs and also in the reduction of the labour required. A possible solution to address the problems of labour availability and scaling up the harvesting of the crop is the incorporation of robotics.

The development of the civilisation humans have tried to domesticate the animals. Initially dogs were known to be the first pet domesticated by humans followed by the domestication of other animals like cattle, horses, sheep etc.

14.1 Introduction

When humans started to domesticate the animal, they have tried several ways to control them. Generally these animals are released in free space to graze and one of the known problems is to prevent them from overgrazing. So building a fence is one of the ways to limit their movement is one viable solution, but building a fence is limited to a smaller area. Since these animals are locked in a large number, so building a bigger fence and moving it every time for grazing is not viable. It can be observed in the history of humankind as that civilisation progressed the use of Shepherd dogs has been one of the widely accepted. Shepherd dogs not only help in shepherding and herding but also prevents these livestock from wolves

The incorporation of robotics will not only automate the process intelligently but also keep a vigil on various aspects of livestock management. In recent years there has been a substantial development in this regard. The development of robotic dogs for shepherding and herding purposes has found a lot of increment developments. SPOT developed by Boston dynamics and SwagBot developed by University of Sydney, are well-known robots developed in recent times for the purpose.

These robots are equipped with multiple sensors like LiDAR, gas and heat sensors, high-resolution cameras etc. The array of sensors are used to capture the data in real-time and is then used for decision-making processes. Also these reports are built to be rugged and can navigate on a variety of terrains.

Milk revolution with change in technology is gaining attention in India. Robotic milking reduces labour and increases efficiency irrespective of large dairy farms. A typical system requires a large camera- and spray-system robot. When activated to apply the disinfectant, the robot sends a six-foot- long pipe with the sprayer under the cow. These floor-mounted robots require expensive installation into the floor of the milking parlour, as well as fencing for employee protection.

15.1 Introduction

Mechanical draining has increased broad acknowledgment, especially in Western Europe, as an approach to lessen labor on dairy ranches, increment creation per cow, and improve the way of life of dairy ranch families draining 40 to 250 cows (De Koning, 2010). The developing ubiquity of this innovation is obvious in its fast pace. In 2009, the evaluated number of automated dairy ranches overall was 8,000 (De Koning, 2010). Only 6yr later, Barkema et al. (2015) proposed that this number had dramatically multiplied to 25,000 dairy ranches around the world. The level of groups utilizing this technology is most noteworthy in Scandinavian nations and the Netherlands (Barkema et al., 2015). Broad selection in these nations proposes in any event a proportion of accomplishment in helping dairy ranchers accomplish more noteworthy work productivity and a superior way of life, yet field experience recommends that wide variety exists in the measure of work spared and in the general fulfilment of early adopters.

Ornamental horticulture consists of floriculture and landscape horticulture. Each is concerned with growing and marketing of plants used to beautify the outdoor environment and with the associated activities of flower arrangements and landscape designs. Ornamental plants provide comfort and peace in our everyday lives. Floriculture is a dynamic, global, fast growing industry comprises of cultivation and trade of cut flowers, loose flowers, potted plants, foliage plants, dried flowers and value added products etc and is becoming popular in both domestic and export markets (Rikken, 2010). In the recent years, ornamental horticulture has emerged as a profitable agri-business in India due to improved living standards and growing consciousness among the citizens to live in environment friendly ambiance. Now-a- days this activity has assumed the commercial status with great potential for generating gainful self-employment among small and marginal farmers. Globalization of the Indian economy and subsequent liberalization of the Seed Act paved the way for the advent of protected cultivation of flowers in the country resulting in increase the production of quality floricultural products witnessing their presence in the international flower markets. The production and trade of floriculture has exhibited considerable increase consistently over the last decade in the country.

Flowers and ornamental plants have been associated with mankind since time immemorial, as they have been used for religious offerings and other social ceremonies. Loose flowers are mostly grown for worship, garland making and decoration. Cut flowers like rose, chrysanthemum, carnation, gerbera, anthurium, orchids and lily are mostly grown for export purposes. Some of the flowers are also edible with their nutritional value e.g. Dahlia tubers, lily, tapioca etc., mainly their roots are rich in starch and even dahlia roots are considered good to cure the cancer.

A garden is a place where ornamental plants are grown to put on display various forms of plant life which are purposely intended for ornamental or practical use or both. Now days we often use the term landscape gardening, Landscape architecture and Landscape design. Landscape gardening can be defined as arrangements of trees, shrubs, climbers and variety of other plants in concert with the building, walks, drives, artificial and natural features for the use of humanity while Landscape architecture is the art of arranging land and landscape for human use convenience and enjoyment. A good landscape design determines the characters of objectsto serve a certain purpose known in advance.

The subject garden planning is diverse and complex and very difficult to symbolize all ideas of wholeness. In modern living consciousness of interior decoration including furniture,woodwork,wall furnishing, carpets painting also needs careful setting and the services of specialist are considered necessary for this purpose. In order to achieve a rewarding result a garden should be designed carefully as it is semi-permanent feature and frequent change in design is not possible.

Principles of design steer designers to organize elements for a visually pleasant landscape. A melodious composition can be achieved through the principles of proportion, repetition, order and unity which are alllinked and application of one principle assists to achieve the others. By using these principles, two important concepts in garden design i.e. physical and psychological comfort can be achieved. Landscape that has order and repetition creates more psychologically comfortable feeling. Psychological comfort is also affected by the sense of satisfaction that a spectator perceives from a harmonious landscape. Users feel more physically comfortable and secure in a landscape with proportions compatible to human scale. Garden design combines the aesthetic beauty, artistic knowledge and at least the principles of gardening. In order to layout good garden some fundamental principles to be followed

Garden lover has to invent their own styles of gardening commensurate with their climate of site, budget and taste. Gardens fall under three categories when it comes to style - formal, informal and wild.

1. Formal style gardens

Formal style gardens are beautiful in the view and have been popular for thousands of years. Granted, it is not to everyone’s taste but it creates a certain magnificence and persistence that will probably have meaning and importance in garden design for many more years in the future. A formal garden is laid out in a symmetrical or a geometrical pattern. Symmetry is the main characteristic of this style of gardening. Geometrically designed landscapes with trimmed hedges, paired flower beds, straight line planting and equal length of the sides of the area are the main features of formal or symmetrical gardening. The formal design is stiff as all garden features in a straight and narrow way. In the formal design, the land is forced to fit in the plan. In this type, an axis is drawn in the centre of the garden which divide whole of the garden in two equal halves, one half being the exact replica of the other, for every feature, element or adornment. The outline of the whole garden as well as the outline of different parts like flower beds, paths, hedges and lawns are of geometrical shape. These shapes are normally square, rectangular,oval or circular.

The Persian gardens, Mughal gardens and Italian gardens were formal in design. Geometrical formalism also influenced the French and British gardens of the pre- Industrial Revolution.

Turf is an English word, which traces its origin to India from the Sanskrit word “Darbha” means “tuft of grass” or “Kusha” in hindi. Kusha has been mentioned numerous ties even in Hind mythologies (Turgeon, 1985). Turf, is a grass which is smooth, has quality texture and a soothing colour surface that is used in the golf courses, lawns, fields, nurseries, gardens, etc. Turf is a piece of earth of about 5 cm thickness with grass thickly grown over it. Turfgrass has become increasingly important in today’s society as people’s needs increase for recreation, comfort and aesthetics. Turfgrasses are considered as major component of landscape industry which provides aesthetic value. They provide arena for various functional, recreational and social activities.

Turfgrasses enhance the appearance of land and increase the utility of sports fields, lawns, parks, golf courses and other greenbelt areas in and around urban as well as sub urban centres. They improve the environment of urban centres by reducing erosion, temperatures, noise, dust and glare. And, turfgrasses improve the safety of sports fields and playgrounds by adding resiliency to the playing surface. Turfgrasses are increasingly being used by National Highway Authority of India for reducing dust pollution and decreasing vehicle glare by planting on central verge and sides. Only turfgrasses are used by airport authorities for planting besides runway. The grasses being of perennial nature also help in carbon sequestration thus helping combat climate change. The grasses which grow well on sandy soil will help to reduce the dust and control erosion and dust pollution on river banks.

The turfgrass industry is growing rapidly due to strong demand for residential and commercial property development, rising affluence, and the environmental and aesthetic benefits of turfgrass in the urban landscape. Increased area under aesthetic and utility turfs is mainly because of increasing awareness about the sports, degrading environment and the increase in real estate value. The economic value of the turfgrass industry in India is yet to be determined as there is no single government agency handling or collecting the authentic data on turfgrass cover, use or import. All the agencies dealing with turfgrasses are either private companies, nurseries or corporates. But, according to the scarce data gathered by golf associations, sports experts and Association of Indian Nurserymen, turfgrass industry covers an area of more than 30000 acres, in which around 6000 acre is under turfgrass cultivation (sod production). States leading in turfgrass cultivation and marketing are Karnataka, Andhra Pradesh, Telangana, Uttar Pradesh, Haryana, Maharashtra, etc. The total number of international cricket grounds in India are 50 and 8 are under construction, more than 520 domestic cricket grounds and athletic fields are also in operation. Indian turfgrass industry is growing around 10 per cent annually. Landscape business contributes 2-3 per cent of total construction and turf has 50 per cent of landscape business.

Annual flowers are a cluster of herbaceous plants which grow from seeds, produce flowers, set seeds and complete their life-cycle within one year or one season. They offer a gorgeous display of colours within the garden. Whether it is a small homemade garden or a giant public garden, it is incomplete without beds of annual flowers. They enhance the ornamental value of a garden within a small span of time. At their blooming time, one feels elated when rainbows of colours appearin the garden.

Classification of Annuals

Flowering annuals are grown in beds and pots. They’re used for several purposes in the garden. In beds, they are grown individually with or without perennial plants in borders. They are developed in hanging baskets, window boxes or rock gardens, for training on walls and trellises and for planting in the form of edges, borders or ground covers. Dried flowers of some annuals are similarly used for interior decoration. Some annuals provide sweet fragrance.

1. Based on season: the annual flowers are divided into 3 groups—winter, summer and rainy season.

Shrubs are defined as woody, semi woody or herbaceous perennial plants, branches arises from the base of the plants and grow up to height of about 0.5 to 4.0 meters. These plants are commonly erect and bushy. Most of the shrubs are very hardy, require little attention and grow in all types of soils. Although some plants flower almost throughout the year, in most cases it is seasonal and selection can be made in such a way that some plants in the shrubbery will be in bloom in different seasion of the year. Shrub flowers regularly every year and produce flowers of almost all the important colors white, light yellow, golden pink, scarlet, crimson, violet, blue, and some are sweet scented.

In gardens, shrubs are usually planted in three ways:

(1) In the form of shrubbery, on the long strip of land where taller shrubs are grown at the back with medium height in middle and dwarf once at the fronts. Colors of flowers and time of flowering are also considered so that shrubbery remains colorful throughout year with bloom and foliage.

(2) In small garden or to break monotony of open space shrubs are often grown in groups and in this case few plants of the same variety or of different species are selected.

(3) Shrubs are also grown as a specimen plant or in only one row along the border of the garden or a wall.

Shrubs are used in gardens for decorative purposes as these shrubs are found more in ornamental and provide a variety of interests. They are evergreen and best against noise and dust. Any perennial woody, perpetual and thick plant of relatively low height that branches into a few stems or trunks arising from the ground base is known as shrub. They are littler than a tree but taller than herbaceous plants. They are also called as bushes when they are much-branched and dense. They grow upwards up to 0.5-4.0meter and may be flowering and ornamental. Shrubs play important role in permanent landscaping i.e. formal decoration which contributes pattern, colour, fragrance and utility. They may be either evergreen or deciduous in nature. Some shrubs have attractive foliage, flowers and attractive berries. Shrubs are planted as borders on the sides of paths and at the corners of lawn in a curving line. Shrubs are used for back ground, boundary wall, screen, shade, wind breaks and foundation planting. Hence, knowledge on the form, growth habit and habitat is essential to select the shrubs for planting. Shrubs are important part of landscaping or landscape designing is an art of modifying the overall appearance of a given piece of land using different ornamental plants. It is an artificial process. A garden or national and international playgrounds are the example of artificially landscaped area. Ornamental plants are a group of different flowering, foliage and stylish plants. These plants are used for the beautification of selected part of a site or other places.

Climbers are the group of ornamental plants which possess weak stem and climb up the support with the help of certain modified organs to reach the top and receive sunlight and air. Climbers enhance the beauty of any garden provided they are selected carefully depending upon the availability of space and the orientation of the building. The growth habit, mass effect of foliage and diverse flower colour give charming appearance to the climbers for their characteristics.

Ornamental climbers are commonly used to train on suitable supports such as arches, pergola, trellis, along the walls and trees. These are most suited in congested regions prone to scarcity of space especially in urban environment.

Trees are amazing nature’s creations that are not only important for mankind but also sustain ecological balance in nature. They are the source of livelihood and provide valuable raw material for manufacture of household utility products. They are important from spiritual aspect and have been exhaustively described in ancient Indian texts with their significant Ayurvedic and other potential health benefits. Botanically a “tree.” is a large, long-lived (perennial) woody plant that attains a height of at least 6 m (20 ft) at maturity. A tree possess certain characteristic features such as a trunk (single main self-supporting stem) which gives off spreading branches, twigs and foliage to make a crown. Since the diameter at breast height (dbh) of trees is determined internationally at 1.35 m (4.5 ft) above the ground, a tree must be un-branched at least up to 1.5 m (5 ft) from the ground.

Growing foliage and flowering potted plants in the home is a great way to develop an intimacy with the nature. Caring and attending the plants gives us immense pleasure and satisfaction, especially retiring after day long working schedule. Now a days, wide variety of houseplants are available that can accommodate almost any indoor location in terms of available space, light and management factors. Research carried at National Aeronautical Space Agency (NASA) has shown that having plants in the home or office, especially in a closed air-conditioned environment, can be good for your health and well-being.

Our indoor environment

It is surprising to know that our comfort zone environment may have 2-5 times the pollution levels than outside air. Although, the magnitude may vary and could potentially reach 100 times depending upon the size of building, occupants, provision of ventilation, volatile organic compounds (VOC’s) emitted from upholstery and paints. The quality of outside air also determine the indoor air quality that may get mixed-up resulting in elevating the levels of carbon-dioxide (CO₂) and other harmful gases beyond the permissible limit. It has been revealed that the indoor CO₂ levels are substantially higher (3-5 times) than those recorded outdoor. The CO₂ being a narcotic cause drowsiness and loss of concentration leading to decline in performance and productivity of employed staff. This sudden upsurge in CO₂ and other toxic gases evolved from the volatile compounds from paints likely raise the Air Quality Index (AQI) that affects the health and working efficiency of building occupants.

It has been scientifically proved that the equipments installed for ventilating closed environment of residential or commercial buildings are not efficient in removing gases and thereby, to some extent filter only the particulate matter (PM). As per the prescribed standards of World Health Organization (WHO) and American society of heating, refrigeration and air conditioning engineers, the maximum permissible limit for indoor CO₂ is 1000 ppm. The term “Sick Building Syndrome” (SBS) is a very common disorder associated now a dayswith the people working in closed environments, especially that lack ventilation. When the CO₂ levels reach 1500 ppm, symptoms such as sore throat, nasal flow and cough are quite commonly observed among the people, thus affecting their general health and well being. Poor indoor air quality has been a major factor linked to SBS, reducing productivity of employees and also cause impaired learning in children in schools.

Cactaceae family comprises of perennial shrubs or trees characterized with the presence of spines which arise from specialized axillary meristems (areoles), which in some taxa may also bear fine barbed hairs called glochids. A large family consisting of about 124 genera and 1,427 species. It is native to North and South America and widely distributed from Canada to Chile. Nowadays they are found growing in many countries like Australia, South Africa, and Mediterranean countries. They are highly adaptable to drier regions because of their characteristic leaflessness nature. Since cacti are succulent in nature that’s the reason that all cacti are succulents but all succulents are not cacti. Cacti conserve water by two means, first presence of cuticle which prevents water loss and second it is CAM (Crassulacean Acid Metabolism) plant where stomata opens at night and close during day time therefore prevents water loss.

Bonsai is an astonishing art-form, combining horticultural approaches and Asian aesthetics in a distinct way, which reflects the nature’s beauty (Pietraszko and Sobota 2008). The art of bonsai is considered to be originated in Chinese empire (Doyle et al., 2019) and was later adapted by the Japanese, where it has become the integral part of their culture (Ching 1990, Roth 2014). The word ‘Bonsai’ is derived from two Japanese words ‘Bon’ (Shallow pan) and ‘Sai’(plant) which literally means “planted in a container”. The Chinese started creating miniature landscapes in the form of Bonsai during Han Dynasty over 2000 years ago. During the Kamakura period (700 years ago) the Japanese adopted the bonsai art-form and subsequently a different Japanese style form came into existence. This art of bonsai was further redeveloped under the influence of Japanese Zen Buddhism (Doyle et al. 2019).

A bonsai is a nature’s replication of plant in its miniature form, without depicting the human interference too clearly. Thus, they are normal trees and shrubs which are dwarfed by a specific system of pruning-training-wiring. Techniques such as pinching buds, pruning and wiring branches, and carefully restricting but not abandoning fertilizers are used to limit and redirect healthy growth in bonsai. They are different from the pot plants which are mainly grown for either their foliage or floral beauty, but in case of bonsai the whole artistic look of the plant in its miniature form is maintained for years. Bonsai can be grown both outdoors and indoors, especially they are ideal for display in living rooms, verandas, terraces and window-sills etc. The good bonsai specimens are usually hardy species that can be kept outdoors the year round wherever winters are mild. They can be brought into the house occasionally for appreciation and enjoyment. In Japan, they are customarily displayed in a recess area or on small tables in a living room and later returned to their outdoor bonsai stands.

Rose (Rosa x hybrida L.) is the most beautiful creations of nature and is commonly known as queen of flowers. It occupies first position in the international trade. Rose is known for its beauty and is used in worship, bouquets, cut and loose flowers, preserves, garlands, decorations, landscaping, etc. It has gained wide acceptability due to varied growth habits, beautiful shape, dissimilarity in size and form, attractive colour, pleasant fragrance and abundant varieties. These can fulfill the requirement of climbers, trees, hedges shrubs, and edges in the landscape gardening. Commercial products of rose such as rose water, rose attar, gulroghan, gulkand, rose dry petals, rose oil, etc play a vital role in international and national market. Rose hips are one of the imperative sources of Vitamin C and are used for preparation of rose tea. With the ever-increasing demand of novel varieties in the world trade, a large number of varieties are being bred every year with many novel traits. Its share is around 51 per cent of the whole of European markets. In India, 29.41 thousand ha area, producing 301.95 thousand MT is under rose cultivation in the states of West Bengal, Karnataka, Gujarat, Chhattisgarh, Maharashtra (NHB database, 2017). Cultivation of rose such as Rosa damascena, R. bourboniana, R. centifolia is also done for essential oil extraction from rose petals.

Origin and Taxonomy

Rose belongs to the family Rosaceae. The genus is divided into four sub genera of which sub genus Rosa includes nearly all the species (Gudin, 2000). The sub genus Rosa is further divided into different sections of which the actual number is arguable. There are about 100 to 300 species in rose based on various reports. The rose genome is complex consisting of five haploid chromosome sets each made of seven chromosomes. (Nybom et al., 2005). The chromosome number of wild species varies from 2n = 2x=14 to 2n= 8x=56, with most of the species being diploid or tetraploid (Nybom et al, 2005). Rosa x hybrida L. is not a species in botanical terms, however, is a highly complex artificial species (Gudin, 2003) that may be used to describe the modern rose cultivars.

Carnation (Dianthus caryophyllus L.) is one amongst the commercially important cut flowers traded worldwide. The genus Dianthus has about 300 species of annual, biennial and perennial herbs of which Dianthus caryophyllus is the most important species commercially. The genus Dianthus in Greek means ‘Flower of Zeus’ or ‘Divine Flower’. Linnaeus chose the species name, caryophyllus, after the genus of Clove, as the fragrance from carnation is reminiscent of clove. It is genetically a quantitative long day plant based on its photoperiod requirement (Blake, 1955). The Dianthus species are adapted to the cooler Alpine regions of Europe and Asia and are also found in Mediterranean coastal regions. Carnations were the first flowers to be cultivated on commercial scale in high altitude areas of tropics for export to Europe and North America.

It is cultivated throughout the world. The largest growing areas of carnation are in Bogota and Colombia. Carnation is also grown in Italy, Spain, Kenya, Sri Lanka, Canary Islands, France, Holland, Germany, Israel and USA. In India, main production areas are located around Pune and Bangalore. It is also being grown in Solan, Shimla, Mandi, Kullu, Chamba, Sirmour, Bilaspur and Hamirpur districts of Himachal Pradesh. As per the State Department of Horticulture - Himachal Pradesh, carnation occupied 44.07 hectares out of 705.77 hectare total area under floriculture in the state during 2018-19. The acreage of carnation is still expected to increase because of the favourable climatic conditions for its cultivation in different parts of Himachal Pradesh and other hilly states of the country.

In India, depending upon the regions, there is a wide difference in temperature, light intensity and humidity which not only affect the yield and quality of the flowers but also limit their availability for a particular period of the year. To produce quality flowers, carnation needs to be grown under cover, that is, in greenhouse which provides the plants with the optimum condition of light, temperature, humidity and carbon dioxide for proper growth and to achieve maximum yield of best quality flowers. Though, there are different types of the greenhouses, naturally ventilated polyhouses are preferred in mild climate in which temperature is reduced by ventilation (Ryagi et al., 2007).

Chrysanthemum takes its name derived from the Greek word chryos meaning gold and anthos meaning a flower, as many species have yellow flower heads. The genus Chrysanthemum belongs to family Asteraceae. It is herbaceous perennial plant. The genus comprises some 200 species of annuals, perennials and shrubs from northern temperate zone (chiefly Europe and Asia), whereas some researchers claim it was originated only from China. Though botanists have retained only the annual species under the genus Chrysanthemum (Beckett, 1983; Dole and Wilkins, 1999).

Annual chrysanthemums which are propagated through seeds. Annual chrysanthemum comprise ofthree species viz, Chrysanthemum segtum (corn marigold), Chrysanthemum carinatum (tricoloured chrysanthemum) and Chrysanthemum coronarium (crown daisy or garland chrysanthemum). The crown daisy or garland chrysanthemum (C. coronarium) is a native from Southern Europe, branching annual with finely cut foliage reaching a height up to a metre, size of flowers varies from 2.5 to 4 cm and colour is usually in shades of yellow and white with cream zone at the center (Vishnu Swarup, 1967).

Importance and Uses

Chrysanthemum is the number one dollar earning flower in the United States and cultivars suitable for growing throughout the year have been evolved there. The members of National Chrysanthemum Society run into thousands in several countries. It ranks second (next to rose) in the international cut flower trade. In India, it occupies a place of pride both as a commercial flower, garden plant, pot plant and as a popular exhibition flower.

Large number of chrysanthemum cultivars which exhibit wide variation for characters like growth habit, size, colour and shape of blooms makes chrysanthemum suitable for varied purpose. Its erect and tall growing cultivars are suitable for background planting in borders and as cut- flowers. The dwarf and compact growing ones are suitable for front row planting or pot culture. The decorative and fluffy bloomed small flowered cultivars are ideal for preparation of garland and hair decoration. The extra large- bloomed cultivars are prized for their exhibition value. Certain species like Chrysanthemum cinerariifolium and Chrysanthemum coccineum are cultivated as sources of pyrethrum, a natural insecticide.

Gerbera (Gerbera jamesonii Bolus), commonly known as Transvaal Daisy, Barberton Daisy or African Daisy, belongs to the family Asteraceae is one of the most important cut flowers in domestic as well as global market. It ranks sixth among the top ten cut flowers. Gerbera can successfully be grown in the plains as well as in the hills. In India, its cultivation is confined mostly to Kalimpong, Bangalore and Pune. The flowers are known for long vase life (Chauhan, 2005) and good rehydration capacity suitable for long distant transportation. It is a diploid species with somatic chromosome number 50 (n=25).

Importance and Uses

Gerbera is very fashionable and widely used as a decorative garden flower and cut flower (Kanwar and Kumar, 2008). It is ideal for garden decoration as a bedding plant, pot plant and suitable for growing in rock gardens. It is also used in interior decoration in vases, flower arrangements and in bouquets.

Gerbera viridifolia is referred as ‘the herb of milk’ in the eastern Cape and is probably used to stimulate milk production in cattle (Dold and Cocks, 2002).

Orchid is a valuable flowering plant belongs to family Orchidaceae. It is considered that the family recognise for maximum number species ranged between17,000 and 35,000 worldwide (Garay 1960; Willis 1973). The word orchid is derived from a Greek word orchis for testicle because of the shape of the root tubers in some species of genus Orchis. India is a reservoir of 1300 orchid species from 184 genera, accounts for nearly 7 per cent of worlds orchids genetic diversity (Arora, 1983; Rampal and Nagrare, 2006) and 1150 species belonging to 164 genera (Satish Kumar and Manilal, 1994) of which about 800 species are found in the North Eastern region of the country (Nagaraju et al., 2006). Apart from species, more than one lakh hybrids developed in orchids. It is found all over the world from tropical to temperate and even alpine region. People always think that orchids are epiphytic only but it is not. It can grow in soil as terrestrial, on tree trunk (epiphytic) and on dead organic matter (saprophytes) and on rocks (lithophytes). Orchids produce unique flowers, affluent for their uniqueness in shape, size and colour, exquisitely attractive; remain fresh condition for long period of time in comparison to other flowers. Vase life of its flowers varied among species and hybrids ranged up to 40-45 days. Orchids are cultivated for trade of orchid species, cut-flowers, potted plants, flower basket, bouquet, stage decoration in high profile meets and functions and also used in many other value-added products (Kuehnle 2007). Many orchid species are used as food like Cymbidium hookerianum, Dendrobium chrysotoxum, D. kingianum, D. cathenatum and many more (Singh et al., 2016), spices (Vanilla planifolia and V. pompona) and medicinal uses (Dactylorhiza hatagirea, Flickingeria macraei, Vanda tessellata and Dendrobium macraei as reported by Ram Pal et al., 2020). The most popular and commercially cultivated genera are: Cymbidium, Dendrobium, Oncidium, Phalaenopsis, Vanda, Paphiopedilum, Mokara, Arundina, Paphiopedilum, Ascocenda and Cattleya in the country and even in the world.

Anthurium is commonly known as anthurium/tail flower/oilcloth flower (Anthurium andraeanum) and flamingo flower/flame plant (Anthurium scherzerianum). The word anthurium is derived from two Greek words viz, anthos meaning flower and aura meaning tail, referring to the spadix. Anthurium plants were growing undisturbed for hundreds of centuries in the rainforests of South America. Samuel Damon, a businessman and politician in the Kingdom of Hawaii brought one species out of hundreds of species of anthurium to Hawaii in 1889 for cultivation in his garden. The plants were introduced by various people in their gardens from Samuel Damon’s garden. It is a tropical ornamental plant valued for its flowers and unusually attractive foliage. In India, it is grown commercially in Assam, Kerala, Tamil Nadu, Karnataka, Sikkim, West Bengal, Meghalaya and Maharashtra. In India, total anthurium flower production is 3230 tonnes with Assam producing highest anthurium production of 2050 tonnes followed by Meghalaya 740 tonnes (Seemanthini and Chandrashekar, 2018). Major markets in the world for per capita consumption of anthurium flowers are Europe (47.80%), United States of America (21.80%) and Japan (16.80%) (Misra and Misra, 2017). In anthurium, various ploidy levels exist like diploid (Anthurium andraeanum and A. hookeri), triploid (A. scandens) and tetraploid (A. digitatum and A. wallisii). Basic chromosome number varies in different species of Anthurium. Most of the Anthurium species have 2n = 30 chromosomes while in some polyploids, it is 2n = 60. However, a few species have 2n = 20 to 124 chromosomes (Petersen, 1989). In Anthurium andraeanum, somatic chromosome number has been found as 2n = 30 + 2B and this species has high percentage of meiotic abnormalities and karyotype differences suggesting its hybrid origin. Anthurium plants need medium care and reach up to a height of 45-50 cm bearing pale white to yellow coloured flowers with orange to red coloured bracts.

Gladiolus, commonly known as ‘Sword lily’ which derives its name from latin word Gladius meaning sword shape foliage. The name gladiolus was originally given by Pliny the Elder (A.D.23-79). It is an important florist crop, cut flower in the domestic and international flower trade. It is relatively easy to grow, suitable for cut flower, pots, hanging basket, bedding and exhibition. An engrossing cut spikes bear a large number of florets on rachis, which exhibit various sizes, forms, with smooth, ruffled, deeply crinkled or laciniated tepals. As a genus it was first proposed by Tournefort and which was accepted in botanical litreture by Linnaeus through his description “Species Plantarum” in 1753 and “Genera Planterum” in 1754. The gladioli are said to be cultivated since the days of ancient Greece. The genus Gladiolus, at present comprises with 255 species (Mishra et al.,1995; Goldblatt and Manning,1998) with wide distribution occurs in Central Europe, Mediterranean region, Central and South Africa are primary centre of origin. Campbell and Bower (2003) mentions about one more species Gladiolus scabridus- a new species 1978 from the mountains of northern Kwa Zulu- Natal and southern Swaziland, restricted to well- drained rocky habitat and where it is endemic. This species has enormous commercial potential have large number of pink flowers. So now number of recorded gladiolus species are more than 260. The gladiolus was brought into cultivation first during Greek period. Gladiolus has been documented in literature since 1578, as evidenced from the record Lyte’s Nievve herbal. This was first time introduced in France and soon after spread to England, Germany, Holland and North America. In India, its cultivation dates back to 19^th century as mentioned in the ‘Firminger’s Manual of Gardening in India (1863)’ that Mr. Charles Gray of Conoor grew some gladioli from corms and seeds at his garden. The European Union gladiolus importing countries are Germany, Belgium, Luxembourg, Denmark, Spain, France, United Kingdom, The Netherlands, Italy and Portugal.

Botanically aster belongs to the family Asteraceae and scientifically known as Callistephus chinesnsis which is basically native to China aster and annual aster. It is native to China and Japan and it is cultivated worldwide as cut flower, loose flower, bedding plant, for flower decoration and for making floral ornaments. It can easily cultivate in the open fields and green houses for the production of cut-flowers. The genus Callistephus derives from two Greek words that is ‘Kalistos’ and ‘Stephos’ meaning ‘most beautiful’ and ‘a crown’, respectively. The name Aster comes from the Ancient Greek word acx^p (aster),, meaning “star”;, referring to the shape of the flower head (Janakiram, 2006).Among various flowering annuals, China aster is having an important position in Indian floriculture industry. It holds the position next to chrysanthemum and marigold among the traditional flowers. In fact, it has widely replaced an already grown annual Chrysanthemum up to greater extent in Indian floriculture industry.

This flower is most preferred for wide cultivation by virtue of its wide variation in attractive color and longer vase life. It is also very much used for beautification in landscape gardening which create mass effect. In India it is cultivated in about 1,020 ha with a production of flower 800 million tonnes. It is commercially cultivated in Karnataka, Tamil Nadu, West Bengal and Maharashtra. In Karnataka it account for 6 % of the total area and 8.8 % of the total flower production.

Tuberose is an important half-hardy, perennial bulbous flowering plant. It belongs to the Amaryllidaceae family and having basic chromosome number (n=30). It is one of the important cut flower among the top ten cut flowers due to its beauty, elegance and sweet pleasant fragrance (Sadhu and Bose, 1973). It is cultivated for its long lasting spike as cut flower as well as loose flower purpose. Tuberose also known as Rajanigandha in Bengali, Gulchari and Galshabbo in Hindi, Sukandaraji and Nelasanpengi in Telegu, Nilasompangi in Tamil and Sugandharaja in Kannada. It is suitable under protected cultivation as well as open field condition (Brundell and Steenstra 1985). It has a huge economic potential and more demand for cut-flower purpose (Usman, 2013) and essential oil industry (Singh, 1995). Due to its immense export potential, cultivation of tuberose is gaining momentum day by day in our country.

Origin and distribution

Tuberose is cultivated all over the world and it is originated from Mexico. Tuberose is commercially producing in various countries such as India, China, Bangladesh, Mexico, Kenya, Italy, France, Morocco, USA, Hawaii and South Africa. In India, it is commercial growing in West Bengal, Karnataka, Tamil Nadu, Maharashtra, Uttar Pradesh and North Eastern part of India. At present scenery tuberose is cultivation in India 7. 95 lakh hectare and cut flowers is estimated to be 27.71 ‘000 MT and loose flowers1560.70 lakh (Anonymous, 2013).

Zingiberales is an important order in Kingdom Plantae with eight families in which most of them are important as far as commercial horticulture is concerned. The order includes fruits (bananas and plantains), spices (ginger, turmeric, cardamom), medicinal (arrowroot, galangal) and ornamental (Heliconias, Bird of Paradise, Marantas, Canna, Costus, etc) plants. Among the ornamental zingiberales, plants of Strelitziaceae and Heliconiaceae are gaining popularity for its aesthetic preferences and marketable cut flowers. The unique colour and enhanced vase life of inflorescences makes them as flowers of choice. The plants of other families such as Marantaceae, Cannaceae, Costaceae, Zingiberaceae, Lowiaceae and Musaceae are also gaining momentum in floriculture business for their cut foliages and inflorescences. Some plants such as calathias are admired as potted plants and for indoor gardening.

Dahlia (Dahlia variabilis Desf., family: Asteraceae, origin: Mexico) is regarded as a premium specialty cut flower besides its utilization for garden decoration and growing as a potted flowering plant. The dahlia flower symbolizes elegance, inner strength, creativity and dignity. It is herbaceous rooted perennial valued for their majestic and attractive display of colourful spectacular flowers. The generic name “Dahlia” was coined by Swedish botanist “Andreas Dahl”. Dahlia was introduced in India during 1857 under the auspices of the “Agri-Horticultural Society of India”, Calcutta. Dahlia exhibit wide range of flower from and size ranging from miniatures (less than 2.5 cm across), to giant (more than 40 cm in diameter). Dahlia flowers profusely and its easy cultivation have made these very popular worldwide. The commercial value of this crop has been exploited in certain countries only. The Netherlands is claimed to be the largest producer of tuberous rooted dahlias. Other countries cultivating Dahlia as a specialty cut flower are Japan, France, South Africa, the U. K., Italy, Germany and the United States. The commercial cultivation of dahlia in Indian subcontinent is limited to hills and plains of Eastern India (Misra and Misra, 2017).

Holland takes the lead in dahlia bulb production cultivation neeary 400 ha, followed by France and Chile. There are 41 international associations concerned with the cultivation and spreading awareness about dahlia as a potential specialty cut flower and flowering potted perennial. Societies such as National Dahlia Society in the UK, the American Dahlia Society (ADS), other groups of New Zealand in European countries, France and Germany have been maintaining Dahlia germplasm for developing novel flower colour and breeding dahlias for their uniform and profuse flowering, longer flower duration, stem sturdiness and longer vase life.

Lily is one of the most beautiful and popular ornamental bulbous flowers. They belong to the genus Lilium of the family Liliaceae, which comprises of 110 species classified into seven taxonomic sections: Lilium, Pseudolirium, Martagon, Sinomartagon, Archelirion, Leucolirion and Oxypetalum. All species are distributed over the mountainous area in the Northern Hemisphere (10° to 60°), mainly in Asia, North America and Europe. Especially, China, Nepal, Korea and Japan are the major centres of lilium gene pool around the world. Being second amongst the bulbous flower crops in the commercial market, Lilium has 4^th position among cut flowers in Flora Holland (Flora Holland Annual Report 2017). In the language of flowers lily is known as symbol of purity and innocence. Majority of cultivated lilies are either hybrids or selections. A large number of species and hybrids can be used in ornamental gardens even though the lily requires little more attention than any other bulbs. Many species of lily (L. leichtlinii, L. lancifolium, Lilium candidum and L. auratum) are also edible and having medicinal value.

Importance and uses

Lilies are one of the most important bulbous ornamental plants with varies uses, grown in border, beds, pots, landscape gardens and are excellent cut flowers of magnificent appearance and beautiful flowers. Roman naturalist and writer, Plinius, recorded that salves and oils were prepared from leaves and flowers of the Madonna lily, or L. candidium. Some species are also known for medicinal and food values, which increased its economic importance many folds. The mucilaginous substance coming out from the bulbs while cooking is used as an ointment for tumours, ulcers and inflammations. The plant was really more of a miniature household pharmacy. Different compounds have been reported in this genus, such as carbohydrates, proteins, fats, amino acids, vitamins, alkaloids, phenolics, flavonoids, carotenoids, sterols, steroidal saponins, and steroidal glycoalkaloids. Alkaloids, steroidal saponins, flavonoids and polysaccharides have been isolated from L. lancifolium and L. brownii var. colchesteri bulbs. Flowers of Lilium candidium contain an alkaloid. Extract of Lilium polyphyllum bulb has been used as refrigerant, expectorant, aphrodisiac, diuretic, antipyretic and tonic (Warrier et al., 1997; Dhyani, 2007). In the customary system of medicine, this species reported to restore health immediately and works as antioxidant in the body. Lily oil is an aid in childbirth. The white lily was also renowned as a cosmetic.

Statice, botanically known as Limoniumis very highly demanded ornamental plant. It is also known as ‘Sea Lavender’ owing to its color and place of growth. The genus name Limonium is from Greek name ‘leimon’ which translates to origin ‘a meadow’, most suitable as many species are found growing near marshy lands or salty areas of sea shore. The statice plants have very wide adaptability and can be seen growing under a wide range soil and climatic conditions like sea shores, marshy lands, deserts and plains etc. Statice figures in top 20 cut flowers sold worldwide but information on its trade, volume, export-import and number of stems sold etc. is not available. The reason for this may be attributed to classification systems, data collection categories and frequently changing nature of the assortments in the international flower market. Comprehensive trade statistics are difficult to locate for Statice. However, Statice figured in top 10 imported products in the Netherlands way back during 2013, 2014 and 2015. Though it is presently not among the top 10 flowers category, still it enjoys the immense popularity among the growers owing to its ease in cultivation and other characteristics. It is cultivated as annual as well as perennial crop, as different species have been domesticated for this purpose.

Jasmines constitute a group of traditional flower crops which are commercially grown for their fragrant flowers and essential oil production. There are trailing, climbing, and erect growing species and cultivars in the genus Jasminum. The genus Jasminum comprises of more than 200 species which are known to occur in different tropical and subtropical regions of the world. The countries growing Jasmines on a commercial scale are India, France, Italy, Morocco, Algeria, North Africa, Egypt and Spain. More than 80 Jasminum species are found in India, of which only four species viz., Jasminum sambac (Mogra / Gundumalli), Jasminum auriculatum (Jui / Mullai), Jasminum multiflorum syn Jasminum pubescens (Kunda / Kakda) and Jasminum grandiflorum (Jai / Pitchi) are widely used for commercial cultivation. Jasmines are commercially grown in many parts of the country as a dry land crop. The leading states in jasmine production are South Indian states like Tamil Nadu, Karnataka and Andhra Pradesh. In India, the commercial cultivation of jasmines are popular in Athoor, Coimbatore, Dharampuri, Dindigul, Erode, Krishnagiri, Madurai, Nilakottai, Periakulam, Salem, Thiruchirapalli, Thirunelveli, Thiruvallur, Tirumanagalam, Vellore, Virudhunagar etc. in Tamil Nadu; Bangalore, Bellary, Kolar, Mysore, Shimoga, Tumkur etc. in Karnataka ; Hyderabad, Khammam, Mahbubnagar, Mancherial, Ranga Reddy, Sangareddy, Vikarabad, Warangal Rural, Yadadri etc. in Telangana; Anantapur, Chittoor, Cuddapah, East Godavari, Guntur, Krishna, Kurnool, Nellore, Prakasam, West Godavari etc. in Andhra Pradesh; Ahmednagar, Aurangabad, Pune, Sangli etc. in Maharashtra; Ahmedabad, Anand, Bharuch, Bhavnagar, Kutch, Vadodara etc. in Gujarat; Gazipur, Jaunpur, Kannauj etc. in Uttar Pradesh; Ajmer, Jaipur, Kota, Udaipur etc. in Rajasthan; Panskura Ranaghat etc. in West Bengal; Guwahati, Hoja, Jorhat etc. in Assam ; and parts of Punjab and Delhi. Jasmines contributes markedly to the national economy and it is estimated that annually more than 20 crores worth of jasmine flowers are produced and traded in India and are also exported to countries like Malaysia, Singapore, Sri Lanka, UAE and United States (Safeena et al., 2017).
