Introduction

In the environment of dwindling water resources and contention of the other sectors, the share of water allocated to irrigation is likely to be decreased by 10 to 15 per cent in the next two decades. One of the ways of improving water scarcity is by enhancing its use efficiency or productivity. Water use efficiency (WUE) is a broad concept that can be defined in many ways. For farmers or farm irrigators, WUE is the yield of harvested crop produce achieved from the available water to the crop from irrigation, rainfall and soil water storage. Improving WUE in pomegranate will be required an increasing in pomegranate water productivity (i.e. an increasing marketable yield per unit of water used by plants and reduction in water losses from the root zone (Chopde and Gorantiwar, 1998; Chopde et al., 2001; Intrigoli et al., 2011). For comprehensive improvement of WUE, it is necessary to raise the following ratios to their maximum: stored soil water content/water received through rainfall and irrigation, transpiration/water consumption, biomass yield/transpiration, water consumption/soil water storage and economic benefit/biomass yield (Frederick, 1993).

Water is most essential thing to sustain life for plants, human and animals. In fact, land and water are the two important natural resources, which play an important role in horticulture production. Irrigation is the lifeline for any crop production. As Pomegranate is mostly grown under water scarce regions of India, so utilization of available water more effective and efficient irrigation system is need along micro-irrigation system offers the way of using water in a most judicious fashion for irrigation purpose. It is based on the elementary concept on irrigating root zone rather than entire land surface which results in higher water use efficiency and improved crop yield. This technique is now being used to mitigate water scare situation in the pomegranate growing regions of the country in enormous way.

Water is the most critical component of life system. Irrigation plays vital role in rising and stabilizing yield and maintaining quality of fruit crops grown in tropical or sub-tropical climate. Micro irrigation is one of the modern and advanced methods of irrigation which is becoming popular in areas having problems like water scarcity and poor quality of water. Since the competition for water between agricultural and non-agricultural sector is increasing day by day, the efficient management of water resources is very essential to meet the water requirement. It is anticipated to reduce water use for agriculture by 70% in the coming decade, where the present day share is 80%. Demand for water is increasing in non-agricultural sectors like industry, energy, domestic use etc. Hence, policy makers and researchers consider water as the main obstacle for growing enough food crops in the coming years. In India where population is increasing at alarming rate, the area under irrigation should go up from 60 million hectares to 114 million hectares by the year 2050. In this context, micro irrigation plays a major role under limiter water agro ecosystem.

Introduction

Hi Tech horticulture is synonymous to cultivation of commercial horticultural crops using advanced scientific technology to make more profit. India is acclaimed globally for production of high value horticultural crops but there productivity is less as compared to many countries. One of the main reasons for low productivity is poor water and nutrient management. The Task Force on Agricultural Development constituted by the National Institution for Transforming India (NITI) Aayog, Government of India in March 2015 has suggested to increase productivity, progress is required along three dimensions: (i) Quality and judicious use of inputs such as water, seeds, fertilizer and pesticides; (ii) judicious and safe exploitation of modern technology; and (iii) shift into high value commodities such as fruits, vegetables, flowers, etc. (Anonymous, 2015).  Hi tech horticulture meeting the entire requirement as suggested by the task force.

Introduction

In the present, India is food secure due to our self-sufficiency in foodgrains, but still,we have to achieve the goal of nutritional security. The horticulture sector is the one which alsoescapes the weather shocks and has the potential to help in poverty alleviation, nutritional security. Again, it has ample scope for farmers to increase their income and helpful in sustaining a large number of agro-based industries which generate a large number of employment opportunities besides helping to achieve the national goal of 4.0 per cent agricultural growth. India with more than 28.2 million tonnes of fruits and 66 million tonnes of vegetables, is the second largest producer of fruits and vegetables in the world, next only to Brazil and China.Onshares, the world fruit production is 11% and vegetables 7%.

Abstract

The term nano technology, buzzword of present day science owes its origin from the Greek word ‘nano’ literally meaning dwarf. It is expressed in terms of dimension one nanometer equals to one billionth of a meter (1nm=10-9m), work on the principle of particle movement, smallest particle accelerate fast in the system. The nano technology deals with manufacturing, study and manipulation of matter at nano-scale (or atomic scale) in the size range of  1-100 nm, called as nanoparticles (Rajan, 2004). Nano technology is one of the most fascinating and rapidly possessing potential to revolutionize in science and technology of medicine and agriculture. In plant pathology, nano technology has potential scope to detection, diagnosis and management of plant diseases. Micromechanical cantilever arrays for selective immobilization and fast quantitative detection of vital fungal spores (Nugaeva et al., 2005). Micro-fabricated chambers designed to mimic some of the features of xylem vessels and discovered that Xylella fastidiosa migrates via type IV pilus-mediated twitching motility (Meg et al., 2005). Antifungal properties of chitosan, chitosan-saponin and Cu-chitosan nanoparticle reveal against phytopatogenic fungi namely Alternaria alternate, Macrophomina phaseolina and Rhizoctonia solani (Sharan et al. 2013). 

Abstract

The development of nano technology creates an excellent opportunity to address complex technical  issues of food supply chain. Failure to embrace nano technology will deny the horticultural sector an opportunity to capitalize on improved product visibility, food safety, quality and security and associated economic benefits. Agricultural and food supply chain management is complex due to the diverse characteristics of agricultural products. There are numerous types of horticultural crops and products, many of which are perishable. In addition, the degree of standardization of some kinds of fruit products and their management is still low. In this regard, the potential application of nano technology to the horticulture is reviewed. Investigation confirms that incremental applicationof nano technology in the horticulture,

Introduction

Sensors are the key components for enabling any IoT(Internet of Things) application. The concept of IoT came as early as 1990 but the practical implementations of the IoT technology is actually becoming possible as the cost of the devices that are needed to create any IoT application have reduced. Sensors are one of the major hardware components needed to form IoT systems and decrease in its price has given a forward leap in developing IoT applications. Sensors have to be uniquely identifiable devices with a unique device ip address so that they can be easily identifiable over a large network. These have to be active in nature which means that they should be able to collect real time data. These can either work on their own (autonomous in nature) or can be made to work by the user depending on their needs (user controlled).

Abstract

The term “Horticulture” is a part of agriculture system which is concerned with the raising of so called garden crops. At present, fruits, vegetables, flowers etc., are grown not only within the backyards, but also in large areas in open fields on a commercial scale where better visualization can be viewed with GIS. It emerged by calculating the present context which allows us to produce a complex view about the land’s characteristics. Most of the GIS in use today have not been designed to support multimedia data and therefore have very limited capability due to the large data volumes, very rich semantics and very different modelling and processing requirements. Use of Remote Sensing (RS) and GIS in natural resource and environmental monitoring has been advocated strongly in present years. The present review gives an idea about the basic concepts of GIS, its components and applications in the agricultural sector particularly horticulture. GIS has been extensively and successfully exploited in various areas using various software’s which are available in current market.

Abstract

Horticulture crops play significant role in improving the productivity of land, generating employment, enhancing exports, improving economic conditions of the farmers and entrepreneurs and providing food and nutritional security to the people. For better management of the existing crops and to bring more area under horticulture crops, updated and accurate database is necessary for systematic planning and decision making. Remote sensing (RS) is an advanced tool that aids in gathering and updating information to develop scientific management plans. Many types of sensors namely microwave radiometers, laser meters, magnetic sensors and cameras collect electromagnetic information to derive accurate, large-scale information about the Earth’s surface and atmosphere. Because these data and images are digital, they can easily be quantified and manipulated using computers. RS can be used in efforts to reduce the risk and minimize damage. The same data can be analyzed in different ways for different applications. A number of studies were aiming at identification of crop, area estimation, disease and pest identification, etc. using satellite data in horticulture. The potential use of RS techniques in Horticulture is briefly reviewed in orde

Introduction

There has been a slow evolution of information technologies in fruit crop production as innovators combined their prior field experience with an attitude of learning by doing while looking for practical applications for farm management. As a suite of technologies became available for use in agriculture production, a new management strategy that combined information with decision making became known as Precision farming. Precision farming is the emerging technology which involves maintaining of crop inputs on site specific basis with reducing waste, increasing the profits and maintaining the quality of environment. The main tools involved in this are Geographical Information System (GIS), Variable Rate Technology (VRT), Global Positioning System (GPS), Yield Monitoring and Remote Sensing.

Introduction

In India, Fruits and vegetables comprises nearly 90% of the total horticulture production. India is now the second largest producer of fruits and vegetables in the world and leader in several horticultural crops, namely mango, banana, papaya, cashewnut, arecanut, potato, and okra (National Horticulture Board, 2015). The total area occupied by horticultural crops in India was 23.69  million ha and total production was 283 million tonnes in 2015-16 (Source: Ministry of Agriculture and Farmers’ Welfare). Different horticultural crops like fruits, vegetables, spices, medicinal plants and plantation crops comprises a large chunk of the total crop sales value of the country and also secures nutritional security of the persons of the country. For systematic and efficient management of existing crops and to bring more area of the country under the cultivation of horticultural crops to increase overall horticultural production in term of time and area, a database must be created for decision making and planning. 

Introduction

Tuberose (Polianthes tuberosa) occupies an important position among commercial ornamental bulbous crops, because of its highly fragrant flowers which can be used in various ways and is essentially a florists flower. The white tubular flowers emit the most popular odour and hence are cultivated on a large scale in some parts of the world for the extraction of its highly valued natural flower oil. The lingering delightful fragrance and excellent keeping quality are the predominant characteristics of this crop. It is popularly known as Rajanigandha, derives its generic name from the greek word Polios, which means white or shinning and anthos meaning a semi perennial bulbous plant. It is commercially cultivated for cut flowers and loose flowers trade and also for extraction of its highly valued natural flower oil. The serene beauty of the flower spikes, bright white flowers, sweetness of blooms and delicacy of fragrance of this ornamental crop, transform the entire area into a nectarine and joyous one. Fresh flowers and value added products of tuberose are exported from India to USA, Germany, United Kingdom, Italy, The Netherland, Japan, United Arab Emirates and Saudi Arabia.

Precision Farming

Precision farming is a concept of proper crop management based on the observation, technology, measurement and response during inter and intra field variability in crops. It is also known as satellite farming or site specific crop management (SSCM).It is an application of right things, in right place, in the right way and at the right time. It has three main requirements viz. first identify various field location, second capture, interpret and analyzed the data in a proper scale & frequency and third, adjust the input with farming practices for efficient economic yields. There are 17 Precision Farming Development Centers (PFDC) located in different agro-climatic zones of India. It is mostly exist in SAUS, ICAR Institute and IIT Kharagpur. 

Precision farming is one of the most scientific and modern approach to sustainable agriculture. It involves management of within field variation and helps farmers to grow crops more efficiently. Precision farming is concerned with the management of variability in the dimensions of both space and time. Variability of resources is a key factor of precision farming.   Precision farming is the application of technologies and principle to manage spatial and temporal variability associated with all aspects of horticultural production for improving crop performance and environment quality. Precision farming calls for an efficient management of resources through location specific hi-tech inventions to produce cost-effective and eco-friendly consumer- acceptable quality products (Mondal and Tewari, 2007).

Abstract

Roselle, or Jamaica sorrel (Hibiscus sabdariffa L.) is a popular vegetable in many tropical regions, cultivated for its leaves, seeds, stems and calyces of which, the dried calyces are used to prepare tea, syrup, jams, jellies and beverages. It is an annual herbaceous shrub belongs to family Malvaceae originated in old world tropics. The fresh calyces and young leaves are used as a vegetable in various cuisines and the plant also yield industrial bio fibre. It also has nutraceutical potential, high pigment content, and nutritional and medicinal properties. Roselle is a drought tolerant crop and cultivated throughout the tropics and subtropics during hot and rainy seasons. China and Thailand are the largest producers and control much of the world supply, where as the best quality roselle comes from Sudan. Many medicinal applications of this plant have been developed around the world. It is used to treat hypertension, pyrexia, dyspepsia, and leukaemia hepato protective, due to its high content of protocatechuic acid. Leaves are emollient and sedative and also show antihypersensitive, antihyperlipidimic, diuretic and anti oxidant properties. Hence, it is an ideal candidate crop for low input multi-cropping system for the food and nutritional security for developing countries.

Abstract
 

Ensure enough food and water to the growing world population and preserve the biodiversity of our planet are among the major challenges of our immediate future. These challenges are essentially addressed to the agricultural world, which is constantly evolving to satisfy the most basic needs of the humankind. The approaches and the possible answers to these big challenges are many and, even if partial, each sustainable solution or innovation can contribute to improve the quality of our life. To overcome the barriers for food and nutritional security microgreens is one of the possible innovative approach in this 21st century. A microgreen is a young vegetable green that is used both as a visual and flavor component or ingredient primarily in fine dining restaurants. Fine dining chefs use microgreens to enhance the attractiveness and taste of their dishes with their delicate textures and distinctive flavors. Smaller than “baby greens,” and harvested later than sprouts, microgreens can provide a variety of leaf flavors, such as sweet and spicy. They are also known for their various colors and textures. Among upscale markets, they are now considered a specialty genre of greens that are good for garnishing salads, soups, plates, and sandwiches.

Abstract

In the recent past we have seen a great upsurge in the production and productivity of food grains as well as horticultural produce which is sufficient to feed our burgeoning population. This way we are self-sufficient to feed our population, but now the major challenge before us is to ensure the nutritional security of each and every individual of the country. Moreover, meeting nutritional security through conventional or molecular breeding demands long time. However, this could be achieved in much shorter period of time i.e., within 2-3 weeks by growing microgreens.Microgreens can be easily characterised by having a central stem with two fully developed cotyledon leaves and mostly one pair of small true leaves.In comparison to their mature counterparts, microgreens of a variety of vegetables and herbs have been reported to be more nutritious. They are rich in ascorbic acids, carotenoids, phylloquinone and tocopherols, which is responsible for its antioxidant properties and also plays a vital role in weight gain modulation, cholesterol metabolism. It may also protects from cardiovascular diseases by preventing hypercholesterolemia. Main problem associated with microgreens are their high price and high perishability and lack of awareness among people about its cultivation practices and health benefits. It demands great attention from the scientific community, to address these problems and make it available in each and every household to ensure the nutritional security of the nation.

Introduction

The demand for agriculture commodity is growing world over and meets the ever increasing targets as per the demand, productivity needs to be raised further. This can be realized in two ways- by increasing area of cultivation and/or through increased efficiency of inputs (both natural and manmade). The scope for the farmer is very limited worldwide and for the latter, the primary input is the solar energy which is most abundant except in few cases like colder regions. In the coming future, the availability of land for cultivation will be a major impendent due to rapid urbanization, hydroelectric projects, dams and rivers, highway roads and also there is a degradation of fertile land due to soil erosion (120.72 million ha), soil salinity and water logging (8.4 million ha) Nath et al., 2007 and Hegde et al. (2015).  Under this situation, multi-storied cropping system will be a viable option to provide food, nutrition and income security to people Awasthi et al., (2008). The available arable land could be effectively utilized for production of field and horticultural crops to achieve nutritional security for the growing population and sustainable income for the farming community. Increasing food production with limited natural resource is a great challenge to the scientific community. Thus, production per unit area of land, time and inputs can be increased by improving efficiency of the rate and extent to which solar energy is harvested for conversion to economic produced.

Introduction

Crop regulation is also known as flowering/ fruiting cycle management. It can also be termed as management of vegetative-reproductive balance. Some of the fruit crops bloom throughout the year without any resting period and produces two or three crops (bahar) in a year but yield and quality is not so good in all crop harvest. It is very essential to understand the flowering and fruiting behavior of crops and which bahar will give good crop with considering all the factors associated with a particular bahar. It is important for the available time to be partitioned to give an appropriate balance between the making of sources of resources which capture and utilized resources efficiently in generating harvestable yield and the filling of sinks for resources; and sink must mature in desired time for harvest. Apart from their importance in the determination of crop yield

The first step of sexual reproduction (Flowering) is of paramount importance in agriculture, horticulture and plant breeding. The change from the vegetative state to the reproductive state is one of the most dramatic events. Flowering leads to an exciting succession of events like anthesis, fruit set, fruit development, maturation and ripening. It provides for the propagation of the species and assists in crop improvement through genetic recombination. Plant growth regulators have remained an important component in horticulture, agriculture from time immemorial, because they were effective means of quantitative as well as qualititative improvement in growth and development of crops. Plant growth and development as well as the responses to environmental factors, are highly regulated by complex and coordinated action of the endogenous hormones (Reddy and Bhagwan, 2014).

Abstract

Mango (Mangifera indica L.) is the one of the most important fruit crop of tropics and subtropics. Mango belong to group of plant in which there is an antagonism between vegetative vigour and flowering intensity. Therefore, any factor that reduces vegetative vigour without altering the metabolic activity and favors flowering which can be possible by the use of growth regulator. Growth retardant that has been widely used in mango crop is paclobutrazol (PBZ) or cultar. Paclobutrazol is N-containing heterocyclic, trizole compound which stimulate flowering by inhibiting gibberellic acid pathway by inhibiting oxidation of ent-kaurene to ent-kaurenoic acid by blocking cytochrome P450 dependent monooxygenase enzyme. It is applied at the rate 2-5g/m of canopy diameter 3-4 months prior to desired date of flowering either by foliar spray, soil drench or trunk application. However, soil application is found more efficient on mango quality production than other. Paclobutrazol has pleiotropic response on mango cultivars. It has been found that application of paclobutrazol is effective in enhancing the protein mobilisation, starch, carotenoid, lycopene, phenol and cytokinin, abscisic acid and enzyme content in treated plant that induce flowering. It has been found that paclobutrazol is capable to reduce mango malformation and make plant tolerant in stress condition.

Mango (Mangifera indica L.) is one of the most important tropical fruits of the world and is commonly known as the ‘King of fruits’ for its high quality fruits which are very popular among the Indians (Sharma et al., 2008). It is an oldest and extensively cultivated fruit crop in India having high socio-economic significance. India is the home of about more than 1000 mango varieties, which originated in the Indo-Burma region (Mukherjee, 1958). India is the largest producer of mango, grown in about 2.3 million hectares with an annual production of 15.02 million tonnes. However, its productivity is only 6.5 tonnes ha against 30 tonnes per ha in Israel. Improvement of productivity in mango continues to be the foremost issue in mango production (Sauco, 1993). Of late, all the mango importing countries are considering the India as a source of quality mangoes due to its varietal wealth and availability. Hence, it is imperative to improve the productivity and quality of Indian mangoes to meet the global need (Balamohan and Gopu, 2014).

Canopy management is the manipulation of tree canopies to optimize the production of quality and quantity fruits. The canopy management, particularly its components like tree training and pruning, affects the quantity of sunlight intercepted by trees, as tree shape determines incoming radiation. Light is critical for growth and development of trees and their fruits. The green leaves harvest the sunlight to produce carbohydrates and sugars which are transported to the sites where they are needed – buds, flowers and fruits. Better light penetration into the tree canopy improves tree growth, productivity, yield and fruit quality. The density and orientation of planting also impact light penetration in an orchard (Proietti et al., 2000). Generally, in close planting, quicker shading becomes a problem. An east-west row orientation results in more shading as compared to the western and southern orientation of trees. The problem of a fruit grower is initially to build up a strong and balanced framework of the trees, then equips them with appropriate fruiting.

Abstract

Plant architecture, plays a crucial role in gathering multiple resources from the environment. As a plant grows, they change its architecture with the surrounding environment for altering available resources. The architecture of the plant is modified through the distribution of assimilate, which conclude the growth rates of different organs. Plant roots expand to acquire soil water and nutrients (e.g. nitrogen, phosphorus) from different soil layers by adjusting their direction in order to growth which transported and allocated to whole plant for maintenance and expansion of plant organs. All plants gradually develop their architecture according to source–sink activities and endogenous signals. This adaptation can result in complex structures. This chapter deals with the importance, different method for changing the architecture   of vegetable crops for improving their yield and quality.

Introduction

High density planting in fruit trees was first introduced in case of apple in Europe during the nineteen sixties, with the development of Malling and Malling - Merton rootstocks. Subsequently, this was experimented in other temperate fruit crops like peach, plum, pear and sweet cherry. Today, majority of new orchards of apple and to some extent that of other fruit crops in Europe, New Zealand, USA and Australia use this intensive system of fruit production profitably Iyer and Kurian (2006). The successful management of trees in any high-density planting system depends on maintaining a balance between vegetative growth and fruiting.

Introduction

Farming and agriculture are respectively defined as the practice of cultivating the land or raising stock and the production of agricultural goods through the growing of plants and the raising of domesticated animals. In the developing countries frantic efforts have been made through research and enlightenment campaigns to encourage farming and thus ensure significant increases in agricultural production in order to feed and sustain the population that is increasing at geometric proportion. At present, the farmers concentrate mainly on crop production which is subjected to a high degree of uncertainty in income and employment to the farmers. In this context, it is imperative to evolve suitable strategy for augmenting the income of a farm.

Abstract

Beekeeping is an agro-based activity which is being undertaken by farmers/landless labours in rural area as an integrated framing practice. It supplements income & employment generation and nutritional intake. Honeybees have been offering services to the society through ensured pollination in crops and providing honey and a variety of other bee hive products viz.; royal jelly, pollen, propolis, bee wax, bee venom, etc. Honey Bees have their vital role in sustaining plants bio-diversity resulting in environmental stability. Mainly five species of honeybees viz.; Apis cerana, A. mellifera, A. florea, A. dorsata, Stingless bees are in used in India.  Beekeeping industry has quadruple benefits: 1) providing self employment to rural and forest based population; 2) production of honey, pollen and beeswax, venom, royal jelly, etc., 3) providing employment to rural educated youths in collecting, processing and marketing of bee/beehive-products; and 4) cross-pollination of various agricultural and horticultural crops and improving their quality and increasing yields.

Introduction

Any kind of garden established on the roof top of building is known as roof garden, which provides the opportunity to cultivate the quality vegetables, fruits and flowers in home. In this system plants and grasses are grown on a nutrition medium placed above a waterproof membrane. Roof gardening is mostly adopted in urban areas. It uses for decorative benefit, roof plantings make available food, manage temperature, hydrological remuneration, architectural improvement, habitats  for wildlife, frivolous opportunities, and in large scale it may even have ecological benefits (Louise, 2009). This considerably increases human health as adding organic cultivation.

Introduction

Earth was a beautiful landscape but man has ruthlessly exploited for his greed specially, in the last century. With rapid industrialization and random urbanization environmental pollution has become a serious problem. Over exploitation of open spaces, ever-increasing number of automobiles and demographic pressure has further aggravated the problem.
 
According to The Hindu, on December 1, 2015 a blanket of smog surrounded Beijing, China, later this smog covered one tenth of China’s area. This situation was recently seen in Delhi, after diwali. It was reported that suspended particulate matter (SPM) content in the air was 14-16 times higher than the permissible limits. So, one of the ways to mitigate this pollution is plating of trees and shrubs as green corridors for abatement of pollution and improvement of environment is an effective way.

Abstract

India is primarily agrarian country and this sector provides livelihood to a major part of the population. The indiscriminate use of agro chemicals since green revolution resulted in adverse effect on the soil fertility; crop productivity; quality of produce and more specifically on the environment system. Organic cultivation is the form of agriculture that relies on techniques such as crop rotation, green manure, compost, and biofertilizers which helps to maintain soil productivity. Organic farming excludes or strictly limits the use of chemical fertilizers, pesticides (herbicide, insecticides and fungicides), plant growth regulators, livestock feed additives, antibiotics and genetically modified organisms. Thus, the importance of organic sources of nutrients was recognized in current scenario in order to get higher yield without disturbing soil health. In this context integrated use of inorganic and organic sources of nutrients in crop production is becoming very crucial for assurance of food security on sustainable basis, which in turn not only improve the soil fertility for sustained crop productivity but also to reduce the cost of inorganic fertilizers.

Abstract

Importance of organic sources of nutrients was recognized in current scenario in order to get higher yield without disturbing soil health. In this context integrated use of inorganic and organic sources of nutrients in crop production is becoming very crucial for assurance of food security on sustainable basis, which in turn not only improve the soil fertility for sustained crop productivity but also to reduce the cost of inorganic fertilizers. Among the various organic sources humic acid plays a major role in the sustainable production of vegetables. Humic acid is a natural bio-stimulant that is derived from leonardite and is among the most concentrated organic material available today. Humic acid is an organic chemical produced by decaying plants and animals residues by a process called Humification. Humic acid is not only increases the yield but also improves the soil fertility, soil productivity, soil structure and texture, promoting plant growth and resistance against various pests, diseases. In this context use of humic acid as organic sources of nutrients in crop production is becoming very crucial for assurance of food security, sustainability and improving soil health.

Introduction

India is bestowed with wide range of climate and physic-geographical conditions and as such is most suitable for growing various kinds of horticultural crops such as fruits, vegetables, flowers, nuts, spices and plantation crops (coconut, cashewnut and cocoa). Its horticulture production has increased significantly over the last two decades and as per the final estimates, by 2013-14, it has increased to about three times (2.87) since 1991-92 and to about twice (1.90) compared to the production in 2001-02. This has placed India among the foremost countries in horticulture production, just next to China. As per National Horticulture Database 2014, during 2013-14, India’s contribution in the world production of fruits & vegetables was 13.6% & 14%, respectively. Total production of fruits during 2013-14 was about 89 million tonnes while that of vegetables was 163 million tonnes.

Abstract

Organic farming is a method of crop and livestock production that involves much more than choosing not to use pesticides, fertilizers, genetically modified organisms, antibiotics and growth hormones. Organic fruit production essentially excludes the use of many inputs associated with modern farming, most notably synthetic pesticides and fertilizers. Organic agriculture, the innovative farming system can build-on and enhance the traditional knowledge and practices of local and indigenous communities. Indigenous Knowledge can be broadly defined as the knowledge that anindigenous (local) community accumulates over generations of living in a particular environment. ITK in fruit production is important for reducing the cost of cultivation, reducing the pollution and also the natural resource base. It is very important to understand these age old practices to address the local problems and to document it before is vanished away.

Introduction : Need to Change

During the era of Green Revolution, India remarkably achieved self-sufficiency in food production with the introduction of high-yielding varieties, extension in the irrigated cultivable land, high use of chemical fertilizer such as Urea and other sources of NPK fertilizers and increase in cropping intensity.During these processes, relative contribution of organic manures as a source of plant nutrients declined substantially. Due to heavy application of chemical pesticides an increase in resistance of insect pests has also been noticed for most of the regular used plant protection chemicals. Health hazards associated with intensive modern agriculture, such as pesticides residues in food products and groundwater contamination are matter of concern. In the progress of green revolution technologies and chemical dependent nutrient management has declined the overall productive capacity of the soil due to no judicious fertilizer use. Such concerns and problems faced by modern-day agriculture gave birth to new concepts in farming, such as organic farming, natural farming, biodynamic agriculture, donothing agriculture, eco-farming, etc. The essential feature of such farming practices imply, i.e., back to nature.

Introduction

Controlled perpetuation of plants is known as plant propagation. Plant propagation can be broadly classified in two types: sexual and asexual. In sexual propagation, the fusion of male and female gametes gives rise to a new plant, whereas in asexual propagation which is also known as vegetative propagation, the development of new plants takes place without the fusion of male and female gametes, that is, the new plant develops from vegetative plant parts. Various techniques of asexual propagation are adopted in plant propagation, such as: grafting, budding, layering, cutting, etc. So far cutting and layering are concerned; the new plants are developed on their own root system, but in grafting and budding on the others’ root system. It means that in these two techniques (grafting and budding), two plant parts are joined to form new plants; the one which forms the root system is known as rootstock and the one forming the shoot system is known as scion. Plant propagation is both a science and an art. The science of plant propagation requires knowledge of plant physiology, nursery cultural practices, and characteristics of the particular plant that you want to grow. The art of plant propagation cannot be taught in a book or classroom, however, because it consists of specific technical skills that must be acquired through innate ability or experience and often requires a certain feel.

Introduction

Healthy seeds and seedlings are the first and essential requirement for achieving full yield potential of any vegetable crop. In recent years, vegetable growers have become highly conscious of the importance of quality seeds or seedlings. A major portion of the area under vegetable cultivation in India is now sown with hybrid seeds, which are costly but give higher yields and quality produce. In view of the high cost of seeds, some vegetable crops like tomato, brinjal, capsicum and cucurbits are being transplanted after growing nursery under protected conditions to achieve maximum germination count and healthy plant establishment. Raising of seedlings in plug trays or portrays is one such technology that achieves the above requirement. This technology is fast emerging as agro enterprise in India for its obvious advantage to both the nursery grower and the farmer. Soil-less substrate consisting of coco-peat and vermiculite is filled in plug trays and one seed is manually placed in each cell of the plug tray. However, manual seeding is labour-intensive operation requiring about more labour and time consuming. Mechanized precision seeding of plug trays is, therefore, necessary to enhance the capacity of rapidly growing nursery industry in India.

Abstract

Plant research often involves growing new plants in a controlled environment. These may be plants that we have genetically altered in some way or may be plants of which we need many copies all exactly alike. These things can be accomplished through tissue culture of small tissue pieces from the plant of interest. The latest list of ISO recognizes 109 spices, but only a few are important commercially such as black pepper, cardamom, ginger, turmeric, large cardamom, cumin, coriander, fennel, fenugreek, garlic, saffron and celery. They are extensively used in flavouring food and confectionery, perfumery and soaps and also as colouring materials. Many of these groups of crops have medicinal properties and are used in many Ayurvedic and Unani medicines. Inspite of the rich diversity and importance, the productivity of spices is low in India. Spices are an important group of economic plants with large genetic diversity in the Indian subcontinent and need to be conserved through in- vitro methods. Conservation of the germplasm using traditional method of field maintenance is problematic, normally labour intensive and also face risk of germplasm loss due to pest/pathogen attack or natural disasters. To minimize the problems of their conservation and increasing interest has been shown to use plant tissue culture. In vitro conservation of germplasm has been reported in various crop species including the spices black pepper, cardamom, ginger, turmeric, large cardamom.

Abstract

A perennial plant or simply perennial is a plant that lives for more than two years. The term is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials. in vitro technologies are continuously expanding in the field of biology. Plant tissue culture has become a general title for a very broad subject. Commercial use of micropropagation is still limited, because of its relatively high production cost resulting mainly from high labor costs, low growth rate in vitro, and poor survival rate of the plantlets during acclimatization. Micropropagation of woody perennials is essential due their importance in production of secondary metabolites, which are playing a vital role now a days. Stages of micropropagation i.e mother plant selection, establishment of the aseptic culture, multiplication, root regeneration and transfer to the natural environment, which are systematically reproduced in many protocols which will aids in micropropagation studies of many woody perennials. Thus the review of present study attempts to provide a comprehensive account on micropropagation of woody perennials complementing conventional programmes for improvement.

Introduction

India is a rich center of plant diversity due to varied climatic conditions as well as soil qualities which provide a better platform for the diverse plant groups. In India around 45000 plant species are spread over the area (Mayers, 1988). These plant species multiply and produces the new plant. The multiplication of plants is termed as propagation and the art of propagation is as old as civilization of human being. The history of civilization began with the propagation and growing of plants. Plant propagation was in practice in pre-historic period. However, the propagation process has got commercial popularity only recently. The success in plant propagation depends on a thorough knowledge of the growth of plants, choice of suitable method and technical skill. In nature, plants multiply naturally to perpetuate themselves. Now-a-days, propagation practices have been totally modernized and became advanced from field to in vitro. Variation in plant propagation can be observed in the nature like some plants are producing many seeds for future generation with their unique type of dispersal mechanism. Among a large

Abstract

Brassica vegetables belonging to family Brassicaceae are one of the most important groups of cool season vegetables. Initially, these crops were confined to Europe and other temperate regions. But, after the Second World War, their cultivation has spread to tropics and sub tropics as well. All the members of this group have originated primarily from the common ancestor wild cabbage (Brassica oleracea var. oleracea) and are fully cross-compatible with each other. In general, these are highly cross pollinated crops and have shown preponderance of non-additive gene action for most of the economic traits thereby suggesting the relevance of heterosis breeding. In the absence of appropriate genetic mechanism for the production of hybrid seed with ease at relatively lower cost, heterosis in a crop is of no practical value. Fortunately, the presence of natural genetic phenomenon of sporophytic self incompatibility and male sterility (particularly CMS) in brassica vegetables has proved instrumental in commercialization of hybrid seed production.
