Abstract
 
Drying is one of the most popular methods used for preserving products and extending their shelf lives by reducing moisture content to a low level to prevent microbial spoilage and moisture-mediated deteriorative reactions. As an efficient technology with high heat and mass transfer rates, impingement drying has been commonly used in various industrial drying such as tissue paper, textiles, photographic films, coated paper, nonwovens, carpets, lumber etc. In the past two decades, air impingement technology has got more and more attention in the field of food and agricultural products processing.

Introduction
Reproduction involves the intricate interplay of physiological processes to ensure the successful growth and development of the embryo and fetus. Three key processes— implantation, placentation, and the establishment of fetal circulation—are fundamental to a viable pregnancy. These stages ensure the fetus receives adequate nutrients, oxygen, and support for development. Below is a detailed elaboration of each process.
1. Implantation
Implantation is the process by which the blastocyst (a hollow structure formed in the early development of mammals) embeds itself into the uterine wall. It is the first critical step in establishing a pregnancy.
Phases of Implantation
1. Apposition: The blastocyst loosely attaches to the endometrium (the inner lining of the uterus).
2. Adhesion: The trophoblast cells (outer layer of the blastocyst) firmly attach to the uterine lining.
3. Invasion: The trophoblast differentiates into two layers: Cytotrophoblast: The inner cellular layer that serves as the proliferative zone. Syncytiotrophoblast: The outer multinucleated layer that invades the endometrium, facilitating deeper embedding.
Significance
Implantation typically occurs 6–10 days after fertilization.
It ensures the establishment of an early connection between the embryo and maternal blood supply.
Successful implantation depends on hormonal regulation, especially the roles of estrogen and progesterone, which prepare the endometrium to be receptive.

Fracture healing is a complex process in which damaged bone restores its original architecture through a cascade of molecular and cellular events. The process of fracture healing is unique, in that it does not form a poorly organized replacement matrix, otherwise known as scar tissue, but rather regenerates the original matrix and retains its mechanical properties. Normal fracture and bone repair follows a known sequence of events includes: haematoma formation, inflammation, angiogenesis, osteogenesis, and bone remodeling.

For the repair of bone defects, a tissue engineering approach would be to combine cells capable of osteogenic (i.e. bone-forming) activity with an appropriate scaffolding material to stimulate bone regeneration and repair. An ideal tissue-engineered bone substitute should possess 3 elements: osteoprogenitor cells, osteoinductive factors, and an osteoconductive scaffold, and is considered as a potential substitute for autologous bone transplantation. Tissue engineering approaches have proven very effective in bone regeneration recently, and the successful repair of bone defects has been demonstrated in larger animals like canine, goat and sheep.

Stem cells from adult tissues are attractive materials for cell therapy, gene therapy, and tissue engineering. These cells generally have restricted lineage potential when compared to embryonic stem cells, and this may be advantageous in certain therapeutic applications. Till and McCulloch in 1961 describes the presence of hematopoietic progenitor cells in bone marrow. After this, the concept of MSCs is brought to light by Friedenstein and co-workers who demonstrated the osteogenic potential of BM cells by heterotrophic transplantation.

INTRODUCTION
Hitching and detaching implements from a tractor is a crucial aspect of tractor operation, whether in agricultural, industrial, or construction work. This process involves attaching various implements, such as plows, harrows, or trailers, to the tractor’s hitch system, ensuring proper functionality during operation, and safely detaching them once the task is completed. Mastering the correct procedures for hitching and detaching is vital for safety, operational efficiency, and preserving the tractor and implement lifespan.
The tractor hitch system plays an essential role in connecting the prime mover (tractor) to the implement, creating a cohesive working unit. Both the tractor and the implement rely on each other to perform, much like the two wheels of a cart.
A “hitch” is defined as a single articulated point or a combination of points and links that allow the tractor to exert tractive effort in the form of pushing or pulling to counteract the draft force of the implement. The hitch point, whether virtual or real, represents the specific location on the tractor through which the “line of push” must pass to ensure effective operation. Proper understanding of this system ensures smooth, safe, and efficient work.
HITCHING IMPLEMENTS TO THE TRACTOR
Hitching implements to a tractor is an essential process, and the method can vary depending on the type of implement being used. The most common method involves using two hydraulic arms and a third high point to attach and level the implement. The hydraulic arms serve as the main tie-down, allowing the implement to be raised or lowered, while the third point is connected through a double-nut bar, which can adjust the length of the tie-down. For larger tractors or implements, this third point can also be hydraulic for easier adjustment. An alternative coupling method is the cup and pin system, commonly used for trailers, balers, or tanks, where a pin is driven through the tractor’s cup and

Introduction Rice cultivation is a means of livelihood for a large number of people from the state of Assam, India (Saikia, 2019). It is related to the cultural aspects in rural Assam where people indulge themselves in traditional as well as modern ways of farming. Like any other north-eastern states in India, rice majorly dominates the Assamese cuisine. It is the primary source of diet in Assam. There are more than 100 varieties that are genetically modified breeds in which indigenous varieties contribute to 20 germplasm (https://www.rkbassam.in/). The different rice varieties of Assam have different culinary applications in both savoury and sweet cuisines. The intermediate and high amylose rice, parboiled or nonparboiled are consumed as staple for major meals while the low amylose rice is mostly consumed as snacks, breakfast cereals and desserts. The major constituent of rice is starch consisting of about 90% of the mass. Thus, the major compositional changes occurring in rice is due to starch. Starch is a polymer of glucose linked by glycosidic bond. It consists of amylose (linked by alpha 1- 4 linear chains) and amylopectin (alpha 1-4 & alpha 1-6 branched chains). On the basis of composition, rice is classified as high amylose (>25%), intermediate amylose (20 -25%), low amylose (7-20%) and waxy or glutinous (1–2%) types (Juliano, 1979).

The eventual objective of promoting IDM is to empower its users to engage sustainable agricultural production with long term positive impacts on human being, poverty and environmental health.The impact of successful implementation of IDM approaches cannot be achieved if IDM is not strategically placed within national policies for agricultural production and protection. There are number of the national policies and related regulations that have direct impact on IDM adoption and scaling up in India.

It is a process by which a act of predetermined activities is carried out in a planned manner, with a view to achieve certain establish objectives.

To implement a project means to carry out activities proposed with the aim to achieve project objectives and deliver results and outputs. It is a highly complex process and it involves a relationship among several system and variables

1. Introduction

Radio Frequency Identification popularly known as RFID is a term used for a radio-enabled device that communicates with or interrogates a tag or smart label, which is embedded with a single microchip processor and an antenna. "This is an automatic identification method that relies on storing and remotely retrieving data using devices such as RFID tags or transponders (Mamdampur and Rajgoli, 2011)". This technology is similar in concept to a cell phone (Singh and Midha, 2008) which refers to the subset of automatic identification that uses radio waves to automatically identify bulk or individual items (Chavan, 2012).While the origin of RFID lie more than 50 years in the past, passive RFID technology is actually only in its infancy (Sarma, 2008).

Abstract

The upsurge in global population rates has triggered a significant escalation in food demand across the world. This is accompanied by urbanisation and a pressing need for sustainable agriculture. In this context vertical cultivation of plants as well as breeding of livestock on vertically inclined surfaces, such as in skyscrapers and other high-rise buildings in urban regions has gained prominence. The dynamics of urban agriculture is captured through the case study of Urbagrow Aquaponics, an urban, aquaponic, soil-free, food garden based in Kolkata. The garden exhibits an assortment of aquaponic systems for growing a variety of vegetables as well as the tilapia and catfish. The systems make use of less water, require less work in man-hours and can grow vegetables in greater density than a traditional soil based food growing endeavour. A feasibility study has been conducted to explore the potential of scaling such a venture across myriad other high-rise buildings across Indian cities.

The major challenge of the present time in agriculture is implementing sustainable development and meeting the food needs of increasing population simultaneously. Agricultural extension always remains an integral part of National Agricultural Policy. At present, agricultural extension has a crucial role to play in the context of growing demands of agricultural production in a sustainable manner. In this situation extension’s traditional task of transferring and disseminating appropriate technologies and agronomic practices would not be sufficient. There is need to view extension for sustainable development in an institutional strengthening context, both in functional and structural.

Variation is inherent in almost all biological populations. In any science, research work, that is, the study and explanation of development changes in a phenomenon can be theoretical as well as experimental. Thus, in order to have solution to a problem the need arises to collect relevant information (called data) their analysis and interpretation through appropriate statistical tools. Statistical analyses help the biologists to draw appropriate conclusions. For instance, in Integrated Pest Management (IPM) the entomologists are primarily concerned with the estimation of insect-pest population, its distribution pattern over time and space, its relationship/fluctuation in population with the prevailing weather parameters and ultimately its control measure through the judicious use of chemicals, biological control agents and resistant varieties etc. There are two broad modes of collection of data:

Introduction

Growth enhancement technologies have been widely embraced in the livestock industry to improve growth, efficiency and carcass traits. For over 50 years, estrogenic and androgenic hormone implants were widely used in the cattle feeding industry, and it is estimated that approximately 97 percent of feedlot cattle in the U.S. receive one or more implants during the finishing phase (Barham et al., 2003; Tatum, 2006). There is a large body of literature that indicates the positive growth enhancement effects which implants impart on growing and finishing cattle and producers have extensively used implants to increase live body weight, improve average daily gain and feed efficiency, and reduce the number of days cattle are on feed (Apple et al., 1991; Duckett et al., 1997;Milton and Horton, 1996; Perry et al., 1991). Likewise, there is a growing body of literature that indicates the positive response on growth and carcass characteristics that finishing cattle have to beta-adrenergic agonists. The hog industry, and more recently, the cattle feeding industry have increased utilization of beta-adrenergic agonists to improve the efficiency of production. While the use of Ractopamine hydrochloride (Paylean^®, Elanco Animal Health, Greenfield, Indiana) has been used extensively in hog production since its approval by the Food and Drug Administration (FDA) in 1999, similar pharmaceutical feed additives have only recently been implemented in commercial cattle feeding operations. Beta-adrenergic agonist use in fed cattle has substantially increased following the FDA approval of Ractopamine hydrochloride (Optaflexx^®, Elanco Animal Health, Greenfield, Indiana) in 2003, and the approval of Zilpaterol hydrochloride (Zilmax^®, Merck Animal Health, Summit, New Jersey) in 2006. The use of both Ractopamine hydrochloride (RH) and Zilpaterol hydrochloride (ZH) have shown to elicit similar improvements in live weight gain, average daily gain, and feed efficiency as those reported in hormone implants (Allen et al., 2009; Avendano-Reyes et al., 2006; Beckett et al., 2009; Elam et al., 2009; Gruber et al., 2007; Kellermeier et al., 2009; Scramlin et al., 2010). In addition, these compounds have been reported to have profound effects on hot carcass weight, Longissimus muscle area and carcass cutability (Gruber et al., 2007; Hilton et al., 2010; Rathmann et al., 2009; Scramlin et al., 2010; Shook et al., 2009; Vogel et al., 2009). It is because of this that cattle feeders have drastically increased use of beta-agonists since their FDA approval, and a growing portion of the fed cattle population receive a dietary beta-agonist supplement that is provided within the final 20 to 30 days of finishing.

The most important use of R programming lies in importing of data files which serves as input for the analysis work. After the analysis is over by using R codes, operators and functions, the output result must also be exported in form of files. The files are imported in form of csv files (comma separated variable), text files or excel files.

Before going to the actual content of the chapter we have to have an idea about csv files. CSV stands for Comma Separated value. It is used to store tabular data, such as a spreadsheet or database. CSV is delimited text file in which the values are separated by commas. CSV files occupy much less space than excel files and also gets imported in a program at a much faster rate than Excel files. CSV Files also does not manipulate data and stores as it is.

Let us consider that an excel file named as ‘plant’ which stores three variables, named as ph, pd and yield is created inside the folder named as ‘My Data’ which is placed in the desktop. Thus the path of the file is “C:\\Desktop\\My Data\\plant”

To import excel file the package will be readxl and the command will be library(readxl)

1. Determination of qualitative nursery planting materials

1.1 Quality assessment of seedlings

Nursery is a place where young/infant seedlings are kept under intensive care until they are ready for planting. The production of quality seedlings begins with the collection of quality seed, nursery establishment, and after-germination maintenance. The quality of plant propagation structures may not be a qualitatively gradable criterion, but it can be indirectly assessed by their relationship to growth, productivity, and vigour. The Dickson Quality Index (DQI) is very useful for assessing the quality of a specific group of seedlings. This is done by selecting some seedlings at random from that group and computing Dickson Quality Index (DQI).

The Export-Import (EXIM) Committee was constituted in the Seeds Division to deal with application for exports/imports of seeds and planting materials in accordance with the New Policy on Seed Development and EXIM regulation.

The Policy reiterated that all imports of seeds and planting material would be regulated under the Plant Quarantine Order 2003 and amendments made their under, Import licences would be granted by DGFT/PPA on the recommendations of DAC.

The composition of the EXIM Committee is as under: (i) Secretary (A&C) - Chairperson (ii) Agriculture Commissioner (iii) DDG (CS), ICAR (iv) DDG (Hort.), ICAR (v) JS (IC) (vi) JS (PP) (vii) Horticulture Commissioner (viii) Animal Husbandry Commissioner, Deptt. of Animal Husbandry & Dairying (proposed to incorporate by the 94th Exim Committee) (ix) Director, National Bureau of Plant Genetic Resources (NBPGR) (x) Plant Protection Adviser (xi) Economics and Statistical Adviser (xii) JS (Seeds) - Member Secretary

A small quantity of seeds sought to be imported would be given to ICAR, or farms accredited by ICAR, for trial and evaluation for one crop season. On receipt of applications for commercial import, DAC would consider the trial/ evaluation report on the performance of the seed and their resistance to seed/ soil borne diseases. DAC is required to either reject or recommend the application to DGFT for grant of import licence within 30 days of receipt.

Agriculture plays a key role in the overall economic and social well being of the country. Though the share of Agriculture in both GDP and employment has declined overtime, Agriculture still forms the backbone and occupies a pride of place :

1. Agriculture contributes 24 per cent to the Gross Domestic Product. GDP was declined from 39 per cent in 1983 to 25 per cent during 1999-2000 and now it 17.32 per cent.
2. Provides livelihood support for more than half of the population in the country. The sector provides employment to 56.7 per cent of the India’s work force.
3. Agriculture has been the source of raw material for industries. Majority of the industries depending on agriculture for their raw materials. Ex: Textile (Cotton, Jute), Sugar (Sugarcane, Sugar beet), Small & medium scale industries like soaps, dyes, medicines, vitamins, preservation of fruits and vegetables, dhal milling, rice husking, Jaggery making, oil crushing, handlooms etc.
4. It provides large part of market for industrial goods viz., seeds, fertilizers, pesticides, implements, machines like pump sets, trucks, tractors, power tillers, sprayers etc.
5. Support roadways, railways, airways and shipways for transport of inputs & produce.

1.1. Definition

Alteration in one or more of physiological processes culminating in a loss of coordination of energy utilization in a plant as a result of the continuous irritation due to presence or absence of some factor or agent.

A plant is said to be diseased when there is a harmful deviation from normal functioning of physiological process (Federation of British Plant Pathologists, 1973).

History of plant breeding
The process of plant breeding takes care of changing or modifying the genetically controlled characters of a particular variety or genotype of a crop. The practice of age-old agriculture uses the process of selection from the existing variability to save a particular quality of seed to grow better crops in the next harvest.
Gregor Mendel who is known as the father of Genetics discovered the law of segregation in the middle of the 1800s. This theory forms the base for the process of plant breeding. The primitive ways used for plant breeding are very different than what modern technology has contributed to the process of plant breeding during the 20th century.
Plant breeding is the science and art of purposeful manipulation of characters of crop species to create new varieties with a set of desired characteristics. Significance of plant breeding has been highlighted especially after the “Green Revolution”.

Cut flowers have become an important segment of modern commercial floriculture because of their high economic value, domestic demand, export potential and employment-generating capacity. This chapter introduces the importance and scope of cut flower production in India and internationally. It examines the economic, social, employment and export significance of flowers and discusses major commercially cultivated crops such as rose, chrysanthemum, gerbera, gladiolus, carnation, lily, orchid, anthurium and tuberose. The chapter also identifies production constraints including labour, infrastructure, cold-chain limitations and market fluctuations, while highlighting opportunities arising from protected cultivation, precision farming, technology, exports and increasing consumer demand.

The association of flowers with mankind is evidenced since dawn of the civilization. For many centuries, flowers play an important role in each and every occasions of life and no social function is considered complete without the use of flowers. Flowers are regarded as the symbol of love, beauty and a gift of nature. In India, there is a popular saying that flowers are associated with man from birth till death.

Floriculture can be defined as a specialized branch of horticulture which deals not only with the cultivation of flowers, foliage plants, climbers, trees, shrubs, cacti, succulents, etc., but also their marketing and production of value-added products from them.

Floriculture is increasingly regarded as a viable diversification from the traditional field crops due to higher returns per unit area. Flowers play a cardinal role in human behaviour and culture, bringing tranquillity and peace of mind. From a symbol of love, flowers have transformed into an industry, generating both income as well as employment. During the past few decades, appreciation of the potential of the commercial floriculture has resulted in the blossoming of this field into a viable agri-business option. The varied agro-climatic conditions prevailing in India and wide availability of natural resources are conducive for production of a large number of flowering and ornamental crops almost throughout the year. The commercial production and marketing of flowers and floriculture products have also increased during recent years due to improved marketing and communication facilities, making availability of these throughout the country and generating a huge employment.

Horticulture is the science and art of production, improvement and utilization of fruits vegetable, ornamental, aromatical medicinal, spices and plantation crops. The word horticulture derived from latin words ‘Hortus’ means garden and culture means cultivation.

The horticulture science can subdivided into different following branches on the basis of product utilization and crop involved.

Pomology: This word is derived from latin word pomus ‘Fruit’ and Greek term logy ‘Science’. The branch deals with the cultivation of fruits called pomology.

Olericulture: It is the branch of horticulture which deals with cultivation of vegetable crops product of which is utilized for culinary purpose after cooking. Olericulture word is derived from the latin word oleris means pot herbs and the english word culture means the culture of succulent vegetables.

Plantation crops: Cultivation and processing of tropical crops grown on a large scale centered around a factory constitute the plantation crops e.g., tea, coffee, black pepper.

Spices crops: These crops are grown and used for providing fragrance and flavouring to various food stuffs e.g., cinnamon, clove, pepper, coriander etc.

Medicinal plants: These plants are rich source of alkaloids and steroids having prophylactic and curative properties for treatment in several diseases e.g., Aloe, Isabgol.

Aromatic plants: Aromatic plants are rich source of essential oil which is used for cosmetic industry e.g., Rose, lemon grass etc.

1.    Total horticulture covers an area of 27.1 m ha and production 305.8 m ton in the country annually (Indian Horticulture Database, 2018).

2.    Fruit crops cover an area of 8.4 m ha and vegetable crops 12.2 m ha. Accordingly, 98.7 m ton of fruits and 182.1 m ton of vegetables are produced in the country annually (Indian Horticulture Database, 2018).

3.    Apart from fruits and vegetables, floriculture industry in India comprising of florist trade, nursery plants, potted plants, seed and bulb products is being observed as sunrise industry.

4.    The developed flower market in the country during 2018 is with area of 0.32 m ha with a production of 2.7 m ton flowers.

5.    The traditional flowers are grown on a large area on a commercial scale. These flowers are mostly grown for loose flower purpose.

6.    Area under cut flowers like rose, chrysanthemum, gladiolus, carnation and orchids is increasing day by day.

7.    Plantation crops are another potential sector with lot of opportunities for employment generation, foreign exchange earnings and overall supporting livelihood sustenance of mankind at large.

The Total Horticulture production of the country is estimated to be an impressive level of 314.87 Million Tonnes during 2018–19.

Production of fruits is estimated to be about 97.38 million tonnes during 2018–2019.

Production of vegetables is estimated to be about 187.36 million tonnes during 2018–2019.

Production of spices is estimated to be about 8.61 million tonnes during 2018–2019.

Plantation crops are another potential sector with lot of opportunities for employment generation, foreign exchange earnings and overall supporting livelihood sustenance of mankind at large.

In short and sweet horticulture supplies quality food for health and mind, more calories per unit area, develops better resources and yields higher returns per unit area.

It also enhances land value and creates better purchasing power for those who are engaged in this industry. Therefore, horticulture is important for health, wealth, hygiene and happiness.

Similar to forest trees these horticultural trees will maintain the ecosphere. They help in transforming the micro climate.

It provides shelter to birds, reptiles and other micro organisms and add to the geo–ecological diversity on the land.

Horticulture means the cultivation of garden plants. The garden plants are comprised of fruits, vegetables, ornamentals etc. The culture covers the operation from raising and planting of saplings to the ultimate use of the products and, as such, it is the most intensive of all the agricultural sciences. However, the concept of growing plants in garden or in an enclosure does not fit well in the changed perspective where large scale cultivation of fruits, vegetables and flowers extending over several square kilometers, in many a place nowadays, delimits the boundary of garden.

Importance of Horticulture

The importances of horticulture are established not only as a source of nutritious foods but also in many other ways which are narrated in the following points:

Social- Due to the long association, the fruits are seen to have a permanent seat in the social life of man. As a consequence, various fruits have acquired their place in art, music, literature, customs and habits of various nations of the world. The description of fruit as symbolic insertion in the poems and literatures, the use of whole fruit plant or part thereof in various social festive and public gathering, and conferring titles to individuals in the name of fruits or naming a region or whole district after the name of a fruit are nothing but an indication of their popularities and social position in various countries.

Horticulture is of immense importance for human beings. Among these major ones are nutritional importance, economic importance, medicinal values, environmental balance, aesthetic value and recreation. These are as follows.

1. Nutritional importance: Healthy body maintains a healthy mind. Human body requires vitamins, minerals, proteins, energy, fibers, etc. for its health. Fruits and vegetables are the chief sources of proteins, carbohydrates, fats, vitamins, minerals, organic acids, fibers, etc. Consumption of fruits and vegetables keeps the human body away from several illnessess and hence are recognized as protective foods; necessary for the maintenance of human health. As per the Indian Council of Medical Research; consumption of at least 120 g of fruits and 280-300 g of vegetables per day per capita is essential. Among vegetables, 80-100 g of leafy vegetables, 100-125 g of tubers as energy source and reamaining as other vegetables. However, the consumption of fruits per capita in India is still low. In countries like Italy, France and USA; the daily fruit consumption is 308, 232 and 223 g respectively. 

The history of gardening in India is older than civilizations of Mohenjo-daro and Harappa. During the pre-Aryan period (around 2500 B.C.), Indians were cultivating flowers and plants of religious significance. Later importance of gardening was not properly understood in India. But presently, importance of landscaping and gardening is realised by planners and landscaping has now become an integral part of any new establishment or property. Due to urbanization and industrialization, pollution has increased considerably and landscaping is one of the best options to reduce the problem. Landscaping is an art of beautifying a piece of land or garden or a landscape with planting materials and non-living materials in order to create a picturesque effect or to imitate nature in that particular land for human use. The importance of landscape gardening can be divided into three categories.

Loose flowers occupy an important position in Indian floriculture because of their extensive use in garlands, Veni, Rangoli, worship, festivals, weddings, decoration and perfumery. Crops such as marigold, jasmine, chrysanthemum, tuberose, rose, crossandra and gomphrena provide livelihood opportunities for small and marginal farmers and rural workers. This chapter discusses the cultural, economic and employment significance of loose flowers, along with value-addition opportunities in essential oils, natural pigments, floral waters, cosmetics and food products. It also examines the national and international scenario, production constraints, postharvest challenges, market opportunities, emerging technologies and prospects for entrepreneurship in the loose flower sector.

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.

Agriculture shapes the foundation of Indian economy and despite the fact that there has been vast industrialization in most 60 years; horticulture still occupies a place of significance. In India, approximately 20-25% of the horticulture produce goes waste due to improper post harvest operations which reduces the growers share in the present marketing arrangements. The grower is getting hardly 25-35 paisa of a consumer rupee. The Value addition activities where the fruits and vegetables are processed, that fetches higher remunerative prices of the produce. Such opportunities are presently not available in rural areas but could be created through selective mechanization of agriculture and appropriate post harvest management and value addition to the harvested biomass in the production catchments.The agricultural produce involves operations like cleaning, grading, drying, storage, milling, packaging, transport, marketing and utilization. At the end of each operation, value is added to the product. The lowest and the highest monetary values of a food commodity are, respectively, when it is in raw and fresh form and when it is in processed and ready to consume/eat form. Post harvest and food processing technology are commodity and location specific. It prevent avoidable post harvest losses and adding value to the fresh agro-produces. It also creates opportunities for employment and income generation. Integration of production agriculture with on-farm primary processing is needed to have higher and sustainable production, productivity and better quality end products for domestic and export markets. It would help in reducing rural- urban disparity and ensuring household food and nutritional security for all at an affordable cost. The technology is available and a wide range of tools, machines and equipment are used in post-production of agriculture. The globalization of trade may compel many agro processing industries to rely on an imported technology at a high cost and the advantage of such technology may be availed by a few who have an exclusive business interest. Majority of agriculture-based enterprises will continue to depend upon indigenous technology and, therefore, R&D through public support has to be strengthened to become globally competitive and serve small-scale food processing sector of the country.

Pineapple [Ananas comosus (L.) Merr.] is an important commercial tropical fruit crop under the family Bromeliaceae. Centre of origin of this fruit can be traced back to Brazil, South America. It is eulogized as “Queen of Fruit” or “Friendship Fruit” or “Haven Fruit” or “Golden Queen”. The word ‘Pineapple’ came from the Spanish word “Pina” based on appearance of fruit which resembles a pine cone. Now, pineapple is termed as “Boon for dry land agriculture”. Pineapple is an introduced crop in India and was first introduced in Goa by Portuguese. The largest producer of pineapple is Thailand and India ranks 6th in the world pineapple production. In India, Tripura, Assam, West Bengal, Kerala are the leading pineapple producers. Pineapple is a CAM (Crassulacean Acid Metabolism), monocarpic (each stem flowers only once and dies after fruiting), herbaceous perennial plant (Baruwa, 2013) and is suitable for cultivation in xerophytic conditions (Baraily and Deb, 2018).

The earliest written references to pineapple are found in the reference of Christopher Columbus, Gonzalo Fernández de Oviedo y Valdés, and Sir Walter Raleigh. They found pineapple growing in the West Indies mainly for for food and wine making. The Portuguese sailors were responsible for early dissemination of the pineapple and introduced it to Saint Helena in 1502. They also carried it to Africa and India by about 1550. Cultivation of pineapple had spread over most of the tropical countries including some of the islands of the South Pacific before the end of the 16th century. Costa Rica, Brazil, China, India, and Thailand are now major growers of pineapple.

India has a substantial livestock population, with animal husbandry acting as a supplementary occupation for about 67% of the rural population. Unlike the commercially oriented farming systems found in Western countries, livestock rearing in India is intricately linked to rural life, where most farmers maintain a small number of animals.
Currently, India’s livestock population surpasses 535 million, which includes 192.49 million cattle, 109.85 million buffaloes, 74.26 million sheep, 148.88 million goats, 9.06 million pigs, and over 850 million poultry birds. Each year, approximately 100 million animals are slaughtered in nearly 4,000 slaughterhouses, resulting in a significant amount of by-products or offals. In tropical regions, a considerable portion of these by-products deteriorates before they can be utilized, primarily due to a lack of knowledge, skills, and infrastructure.
Enhancing profitability in the livestock sector could be realized through improved utilization of animal by-products and waste. Many slaughterhouses presently do not have sufficient facilities to collect and preserve these byproducts in a timely manner. Additionally, retrieving fallen animal carcasses from remote rural areas often presents challenges. The competitiveness of the meat industry can be bolstered by more effective use of by-products. It is estimated that by-products such as skin, pluck, head, feet, and gut can recover approximately 30% and 35% of the live animal value for goats and sheep, respectively. Thus, it is crucial to add value to significant by-products.

Abstract
Urban farming, encompassing practices like rooftop gardening, vertical farming, hydroponics, aeroponics, and aquaponics, involves cultivating, processing, and distributing food in urban areas. With global urbanization projected to reach 60% by 2030, urban farming addresses challenges like rural youth migration, farmland fragmentation, and declining agricultural engagement (currently 49% of India’s workforce). It offers sustainable solutions by producing fresh, pesticide-free food, reducing transportation needs, and combating urban heat island effects. Techniques like hydroponics and aeroponics enable high-yield, year-round crop production in controlled environments, minimizing resource use and environmental impact. Despite high initial costs and skill requirements, urban farming creates employment, enhances food security, and supports urban environmental management, making it a viable alternative to conventional farming in India’s rapidly growing cities.

Introduction
Crop production is weather dependent and almost every crop has been affected by the changing climate. The favourable weather may result bumper production sometimes or even complete destruction of crop may take place under severe weather aberrations. The number of events of sudden aberrations is increasing in a cropping period with the gradual climate change in the recent past. It has been recorded too severe in case of perennial crops. Ready to harvest crops have several times been completely destroyed due to thunderstorm or cyclone in coastal regions or even in main land. Thus, Indian agriculture is being impacted by the climatic changes, and its affect is very much visible now (Aggarwal, 2008). Horticulture sector is not escaped from its’ ill affect and new challenges are coming for production (Singh et al., 2021). The role of adaptation strategy has now been felt crucial (Babu et al., 2021; Banerjee et al., 2022) and importance of agro advisory not only protects the crops from such types of risks but also provide guidance to farmers about the right time for activities in crop husbandry (Adak et al., 2018). Issuance for improving water productivity in water limited areas (Adak and Babu, 2024), micronutrient management for nutrient richness and enhanced yield (Adak et al., 2023; Shukla et al., 2020), rejuvenating unproductive orchards (Shukla et al., 2021; Mishra et al., 2007), disease (Misra et al., 2013; Shukla et al., 2015, 2019, 2020, 2021a,b; 2022; Kumari et al., 2021) and insect pest (Gundappa et al., 2016; 2018) management are becoming very crucial and essential for the benefit of growers.

Vegetable crops, known as protective foods, are important for the healthy diet providing vitamins, minerals, fibre, amino acids and other bioactive compounds. Improvement in vegetable crops is inevitable for better yield, pest or disease resistance, morphological characters, nutritive quality, to adapt with environmental stress, climate change, offseason production, satisfying varying consumer preference etc. Vegetable crops comprise of a large number of species and are rich in diversity. Diverse genetic resources are pre-requisite for any crop improvement programme and vegetable improvement is carried out using exotic introductions, indigenous collection and hybrids/varieties by different breeding systems. Characterisation of genotypes is the description of germplasm giving information on heritable characters so that promising one can be utilised in breeding programme which is the best option for higher yield and other qualities. The morphological, physiological and molecular (biochemical and DNA) traits are called qualitative descriptor and yield, pest/disease resistance, stress tolerance etc are quantitative descriptors that are easily influenced by the environment factors. Apart from the higher production and resistance to biotic and abiotic factors, nutritional traits, flavour, processing qualities that increase the food value is also important in improvement programme of fruits as well as vegetables.

Genetic resources of vegetables available at international and national levels are characterised, evaluated and conserved. With the high diversity of vegetable crops, characterisation and evaluation of genetic resources become a stupendous responsibility requiring extensive infrastructure facilities and varying methods of evaluation (Srivastva, 2012). Genetic resources are characterised on highly heritable traits expressed across the environment. Apart from morphological characterisation, biochemical and molecular characterisation is also conducted that are useful for the identification of biotic and abiotic stress parameters, nutritional and processing quality. Genotype characterisation can be done efficiently using potential of biochemical and molecular markers that help to set up the breeding programme.

Biofertilizers are products that contain microorganisms essential for soil fertility and plant growth when added to the soil. Biofertilizers consist of microbes and living bacteria that promote the fertility of the soil and the growth of plants. Biofertilizers are known to play a number of vital roles in soil fertility, crop productivityand production in agriculture as they are eco-friendly and cannot at any cost replacechemical fertilizers that are indispensable for getting maximum crop yields. Increasing useof chemical fertilizers in agriculture make country self-dependent in food production but itdeteriorate environment and cause harmful impacts on living beings. 

Introduction

Malnutrition remains a pervasive global challenge, affecting millions of individuals across the world, particularly in low- and middle-income countries. Despite significant advancements in agriculture and food production, a large segment of the population still lacks access to essential nutrients, leading to severe health consequences and perpetuating cycles of poverty and underdevelopment (Müller and Krawinkel, 2005). Malnutrition, defined as the inadequate intake of essential nutrients required for optimal health and development, encompasses both undernutrition and over-nutrition (WHO, 2023). While undernutrition, characterized by deficiencies in energy, protein, vitamins, and minerals, remains a significant concern, over nutrition, manifesting as obesity and diet-related non-communicable diseases, is also on the rise, particularly in urban settings (Wells et al., 2020). The consequences of malnutrition are far-reaching, impacting physical growth, cognitive development, immune function, and overall well-being, with long term implications for productivity, economic prosperity, and societal stability (Saunders and Smith, 2010).

Rice, a staple food for more than half of the world’s population, plays a central role in global food security and nutrition. However, conventional rice varieties often lack sufficient levels of key nutrients, such as iron, zinc, vitamin A, and certain amino acids, leaving populations reliant on rice-based diets vulnerable to micronutrient deficiencies and associated health risks (Peña-Rosas and Mithra, 2019). Iron deficiency anaemia, zinc deficiency, and vitamin A deficiency, are among the most prevalent forms of malnutrition worldwide, particularly affecting women and children in resource-constrained settings where rice consumption is high (Dipti et al., 2012)

The profitability of dairy animals depends on milk yield and reproductive efficiency. High-yielding cows require more nutrients to support increased milk production. However, early lactating cows and buffaloes often face a Negative Energy Balance (NEB) due to inadequate energy intake, which hampers their performance. To enhance productivity, it is essential to minimize the extent and duration of NEB. One effective approach is the use of bypass nutrients, which safeguard essential dietary components like fat and protein from rumen fermentation, enabling better digestion and absorption in the lower digestive tract. Additionally, protected starch, chelated minerals, and vitamins can also boost animal performance.
“Bypass Nutrients” are nutrients that undergo minimal fermentation in the rumen, allowing them to remain intact for digestion and absorption in the lower gastrointestinal tract. These slowly degradable nutrients provide a steady nutrient supply to rumen microbes, unlike easily soluble nutrients that lead to sudden spikes in nutrient availability.
Rationale behind the protection of dietary nutrients
The potential benefits of delivering nutrients directly to the intestine in a form available for direct absorption and utilization by the animals are:
1. Prevention of energy losses associated with the degradation and fermentation of nutrients in the rumen, thus sparing available energy for productive purposes.
2. Ensuring that particular nutrients will be available to the host animal in their original form.
3. Taste masking of unpalatable substances.
4. Preventing interactions among nutrients and their oxidation during storage.

Introduction

Environmental Assessment is taken up in this exercise as a rapid assessment technique for determining the current status of the environment and identifying impact of critical activities on environmental parameters. EIA is a relatively new planning and decision-making tool first enshrined in the United States in the National Environmental Policy Act of 1969. It is a formal study process used to predict the environmental consequences of any development project. EIA thus ensures that the potential problems are foreseen and addressed at an early stage in project planning and design. Creation of Environmental Impact Assessment (EIA) system is vital to conform socio-economic development projects to environmental safety and thereby ensure sustainable economic development. In view of the fact that development is an ever-growing process, its impact on the environment is also ever increasing, leading to rapid deterioration in environmental conditions. As such Environmental Assessment provides a rational approach to sustainable development.

It also enables us in carrying out Environmental Cost-Benefit Analysis of projects at an initial stage. It is thus a precursor to detailed analysis of environmental impacts, which are taken up only if a need for the same is established.

Introduction Fish oil is the major source of essential Fatty acids (EFA) for humans. Generally, Fish requires three long-chain highly unsaturated Fatty acids (HUFA) for their normal growth and development including reproduction like docosahexaenoic acid (DHA, 22:6n-3), eicosapentaenoic acid (EPA, 20:5n-3) and arachidonic acid (ARA, 20:4n-6) (Sargent et al. 1993a, 1995, 1997). Like the terrestrial mammals, DHA, EPA, and ARA are all involved in maintaining the cell membrane structure and function of fish but majorly EPA and DHA are considered. Moreover, the EPA and DHA are the major currency as fatty acid for the synthesis of phospholipids, Prostaglandins, and energy etc. However, the biosynthesis of EFA in fish changes in accordance with the relative bioconversion capacity of the PUFA (Linoleic acid and α-Linolenic acid) as shown in figure 01.

Introduction

Mechanized agriculture is the process of using agricultural machinery to mechanize the work of agriculture, greatly increasing farm worker productivity. The effective mechanization contributes to increase production in two major ways: firstly the timeliness of operation and secondly the good quality of work. The requirement of power for certain operations like seedbed preparation, cultivation and harvesting becomes so great that the existing human and animal power in the country appears to be inadequate. As a result, the operations are either partially done or sometimes completely neglected, resulting in low yield due to poor growth or untimely harvesting or both.

Introduction

Evolution of agriculture in India has an ancient tradition of farming since beginning of human civilization. It has been referred in several ancient scripts including Vedic literature and many other ancient scriptures. Therefore, the study consists methods of cultivation, cropping pattern and status of agriculture sector in economy and in human life is essential for strengthen the agriculture sector during recent period. The agricultural sector in pre-independence India was very prone to breakdown and highly unstable. In other words, there was not stable production rate for various crops. The main reason for this was improper infrastructure for perennial irrigation, non-judicious water use, imbalance use fertilizers and manures, uncertainty and uneven distribution of rainfall throughout the year.

Importance of the farmers

Farmers, who put their labour in crop cultivation, grow crops in the land, supply food to the people generation to generation, most unprivileged and unorganized sector of their communities who used to sale labour. In ancient period, workforces were the actual owner of the land and their produce. Gradually, the farmers became paid workforce in the production system.

In the Sanskrit literature described “agriculture is a divine skill taught by sages to farmers for sustenance of life” and shows the high regard for farmers in society. The farmer was the Annadata that stands for the food provider. Farmers raised fodder for animals. Farmer planted and maintained the orchard of blessed trees after that to the village, maintained pasture land, grew herbs and medicinal plants for supply to the village physician, and fragrant flowers for worship at the temple. Farmers nurtured cattle, which gave milk and carried burdens for the community. Farmers, no doubt were the source of raw materials for all artisans and ever increasing population of the country. But farmers are often neglected, exploited, cheated and deprived from their own legitimate cash out. Farmers’ rights were slowly whittled down at first by foreign invasions, later by changes in the land ownership.

Synopsis

Food safety has become increasingly important with globalization due to various factors such as increased volume and diversity of trade in foods, greater public demand for health protection, changing hazards e.g., resistant microbes, more sophisticated methods for detection of hazards, changes in production and consumption pattern, etc. Food safety contributes significantly to food security as unsafe and poor quality food leads to illnesses as well as food wastage. This leads to a strong need to emphasize not only on availability of food but also ensure that the same is safe.

Livestock production is an integral part of agriculture and plays a significant economic role in most developing countries. It contributes to poverty alleviation, food security and provides elements that are essential to the national economy. Livestock production accounts for 40% of the gross value of the agricultural production globally and this figure is likely to go up, as the demand of livestock products is increasing rapidly with the increase in income and urbanization (FAO, 2012). For poor farmers, animal ownership ensures varying degrees of sustainable development and economic stability. Livestock provide a stable cash reserve independent of inflation and are an important source of traction. Livestock are closely linked to the social and cultural lives of several million people. Quality and quantity of feed is essential for optimum animal productivity. Inadequacy of quality animal feed resources is most often the crucial factor for livestock production. The success of livestock is greatly dependent on continuous supply of good quality nutritious feed at competitive price. Poor nutrition of animals has been identified as the major constraints to animal production across the developing world (FAO, 2000). Feed is the major input cost in animal production system, accounting for 65-70% of the total rearing cost.

The food we eat contains nourishing substances called nutrients which are required by human body for proper functioning and maintenance of body health. They are classified into five groups such as:

Carbohydrates,

Protein,

Fats,

Minerals

Vitamins

Chapter Overview

This chapter discusses the crucial concept of gender sensitization in the context of livestock production. Gender sensitization involves raising awareness about gender equality concerns, challenging stereotypes, and promoting equitable practices in the livestock sector. The chapter covers the stages of gender sensitization, offers guidelines for veterinarians and veterinary students, provides real-world examples, outlines a sensitization strategy, and underscores the pressing need for gender sensitization in livestock production.

INTRODUCTION

Intellectual Property Right (IPR) is described as a generic legal term for patents, copyrights, and trademarks, making the feasibility for legal rights to protect ideas, the expression of ideas, and the inventors and creators of such ideas (Brown, 2003). Two types of rights, first, associated with patents and second, associated with copyrights are included into the current IPR regimes. The social purpose behind the IPR is to reward the originator of an invention. Intellectual property serves as a strong foundation of the modern information economy since it promotes software, life sciences, and computer industries, and has becomes a part of most of the products we consume today (Gallini and Scotchmer, 2002).

Objectives
• To understand the critical role of language and communication skills in engineering.
• To explore how communication impacts the effectiveness and efficiency of engineering work.
• To examine the types of communication skills necessary for engineers
• To highlight the significance of these skills in teamwork, leadership, and project management.

Introduction
Language and communication skills are integral to the engineering profession, often determining the success or failure of projects. Engineers are required not only to excel in their technical expertise but also to effectively convey their ideas, collaborate with diverse teams, and manage complex projects. This necessitates a high level of proficiency in both language and communication skills.

The quest for drugs from the sea has yielded a remarkable di versity of natural products mostly from invertebrates such as sponges, tunicates, bryozoans etc. These molecules are either in late stages of clinical trials or have already entered the market. There has been an increased emphasis on marine microorganisms as sources of bioactive compounds over the past decade. Marine bacteria alone constitute 10% of the total living biomass carbon of the Earth’s biosphere and they have unique metabolic and physiological capabilities to ensure their survival in diverse habitats. In the marine environment, some microorganisms associate with living and non-living surfaces and the competition amongst these microbes for space and nutrients leads to the production of bioactive secondary metabolites.

Introduction

Medicinal Aromatic Plants (MAPs) play a valuable and important role in economic, social, cultural and ecological aspects of local communities the world over.

According to World Health Organization (WHO) “a medicinal plant is plant which, in one or more of its organs, contains substance that can be used for therapeutic purpose, or which are precursors for chemo- pharmaceutical semi-synthesis”.

However, a simplest definition of the medicinal plant would be “Medicinal plants are those plants which are used in official and various traditional systems of medicines throughout the world”.

Other definition could be “Medicinal plants are plants that provide people with medicines - to prevent disease, maintain health or cure ailments”.

In Indian traditions, all the plants in this earth are considered as medicinal [Jivak in Astanga Hriday (Sutra: 9-10)].

Aromatic plants are a special class of plants used for their aroma and flavour. Many of them are exclusively used also for medicinal purposes in aromatherapy as well as in various systems of medicine.

It is an established fact that there is no further scope for horizontal expansion of area under plough, as the per capita land is decreasing every year due to unabated increase in human population. Hence, the future need of food has to be met through vertical expansion i.e. more intensification of agriculture. Nearly 40 million tonnes of nutrients in the form of chemical fertilizers will have to be utilized to feed upon an estimated population of 1.5 billion by 2050 AD (Sakai, 2001). However, presently the crop productivity especially rice and wheat has stagnated not only in India but in other South Asian countries also (Mahajan and Gupta, 2009).
