Agriculture is a generic term used to include various types of farming systems, single to multiple crops under various agro-climatic conditions thereby covering crop husbandry, animal husbandry, vegetable growing, floriculture, horticulture, fishery, poultry, goat rearing, piggery, rabbit rearing, sericulture, forestry, vermi-composting, etc. Indian agriculture is a symbiosis of various production systems, a way of life or a tradition, which for the centuries have shaped the thoughts, the outlook, the culture, and the social and economic force of rural life. It is well known for its multi-functionalities of providing employment, cultural heritage, livelihood, social security, family bondage, nutritional and food security. Although agriculture is the main stay of the Indian economy and supports nearly two-third of the work force, yet this is not a highly rewarding enterprise for a large majority of farmers who hold small and marginal size holding. At the same time, the size of the land holding is on a gradual decline, while contribution of farmwomen is on an increase as men go elsewhere in search of better jobs. This sector holds and will continue to be central to all strategies of socio-economic development of the country. A farmer is a multi-purpose entrepreneur (Rajavanshi, 2007).

The horticulture sector of our country is following an increased growth in area and production by 9% and 14 % respectively for the past six years (2015-21). It is reported that the growth rate of horticultural crop production accounts for 2.7% per year. Fruits and vegetables are the major sectors contributing to total horticulture production. As per the report of second advance estimates published by Horticulture statistics division, Ministry of Agriculture and Farmers Welfare during 2020-21, our country recorded the highest horticulture production during 2020-21 with an annual production of 329. 86 million tonnes from an area of 27.23 million hectares and the vegetable sector shared around 196.26 million tonnes production from 10.80 million hectare area. India is the largest producer of okra and ginger and second largest producer of potato, onion, cauliflower, brinjal, cabbage etc. Vegetables also contribute to the export market and onion, mixed vegetables, potatoes, tomato and green chilli are the main vegetables exporting from our country. It is estimated an export of worth Rs. 4969.73 crores from vegetables during the year 2020-21.

Importance of Vegetable Seed Production

Though we are leading in many of the vegetables in area and production, our national average in productivity of the major vegetables is far less compared to the world average. The country s estimated vegetable production by the year 2050 is 375 million tonnes from 15 million hectare with an average productivity of 25 t/ha. Low productivity is mainly because the farmers are still relying on old varieties which are less yielding and susceptible to pest and disease. Unavailability of the quality seeds of newly released varieties is one of the main reasons for this production gap. A substantial increase in yield and quality of vegetable crops can be achieved by adopting suitable agronomic practices, plant protection measures and use of quality seed. Now a days, there is an increased demand for good quality seeds of open pollinated varieties as well as hybrid seeds through which an increased vegetable production can be achieved for meeting the requirement of increasing population. So far, very limited number of vegetable hybrids have been developed and released by public sectors and majority of the existing promising hybrids in vegetables are from private sectors.

Introduction

Seed is a critical and vital input that draws an explicit line between the success and failure of any agricultural production programme. In fact progressive history of agriculture has been a history of seed development and production. The mankind has been attempting to select better seed and employ better seed production techniques volitionally or in-volitionally ever since it divested nomadic life for the settled one. Initial attempts were confined to selection of useful crops followed by selection of better sorts and land races among the available native genetic resources. The introductions, hybridization followed by selection of better types and modern breeding tools inclusive biotechnological interventions have been extensively employed to breed better seed. Considering that research in crop improvement can turn little stone unless the quality seed with desired attributes is made available to the farmers. Government of India set up enforcement of provisions of Seed Act, 1966 for certification of seed as per prescribed minimum standards. Central Seed Certification Board was established in 1972 to exhort the central and state governments for producing genetically and physically pure and physiologically viable seed. The seed production programmes and rules were progressively honed to meet the ground situations. Initially the seed was considered as the exclusive bastion of public sector but the private sector got actively involved in seed production. WTO the seed still became a very open subject and the Seed Act was modified in 1988 and 2001 to permit import and export of quality seed, respectively. Despite of all these positive developments in seed sector, the availability of seed is still far from satisfactory. As on today private sector dabbles in low volume high cost seed due to economics and storage factors but the high volume less cost is still a virgin for private sector and is predominantly done by the public sector. Crop improvement is no more an art and science of improving hereditary of crop plants but has become a starker and competitive business under which the stronger would survive and the weaker get eliminated.

Business was abysmally shattered at the terminal end of the Second World War. This forced some nations to sign some tariff related global

Current Status of Seed Production

Organized seed production in India became possible with the formation of National Seed Corporation (NSC) during 1963, which paved the way for a sound seed industry to come as a consequence of the introduction of hybrid technology during 1961-65. The release of high yielding dwarf varieties of wheat and rice by the 1960’s gave further impetus to the growth of the seed industry in the country. For the total area under cultivation of 26.7 m ha and 65 per cent of the area) insect, disease and weeds (10-40 per cent loss) and also poor shelf-life. Hybrid technology have defined solution in several crop plants specially vegetables, cotton, rice etc. with the development of appropriate hybridization and seed production. In 1990-91, the area planted to ‘bought seed’ was about 10.35 per cent. The total ‘bought seed’ was estimated at around 5.91 lakh tonnes valued at Rs 679.80 crores. 

The basic aim of seed legislation and its subsequent enforcement is to regulate the quality of seeds sold to farmers. So long as Agriculture remains tradition and static, there is little justification for regulating seed quality. However with technological advancement and the systematic application of science to Agriculture, it becomes compulsory to regulate the quality of seeds through seed legislation and its subsequent enforcement to ensure that seed buyers are not made to run undue risks.

TYPES OF SEED LEGISLATION

Seed legislation can be broadly divided into two groups.

1.    Sanctioning legislation

2.    Control legislation

Sanctioning Legislation

Which authorizes, establishes or otherwise legally sanctions such activities as formation/establishment of advisory bodies, seed certification agencies, seed testing Labouratories, foundation and certified seed programmes, recognition of seed certification agencies of foreign countries, appellate authority etc.

Climate change exposes onion production to irregular rainfall, heat, drought, flooding and increasing pest and disease pressure. These stresses can reduce yield, damage bulb quality, increase storage losses and threaten smallholder livelihoods. This chapter uses research literature and case studies to examine resilience at farm, community and supply-system levels. It emphasizes location-specific varieties, crop rotation, micro-irrigation, efficient input use, digital forecasting, protected production, improved storage and reliable cold chains. Farmer organizations, extension services, subsidies and supportive institutions are also important. Sustainable onion farming requires agronomic, technological, socioeconomic and policy measures to function together, enabling growers to adapt to climatic uncertainty while conserving resources and maintaining profitability.

10.1. INTRODUCTION

The development of hybrid breeding methodology in maize and its successful application to exploit heterosis is considered as significant achievement of plant breeding in the present century. 
Even though Beal (1880) suggested for commercial cultivation of F1 varietal hybrids. It was Shull (1909) on the basis of his experiment gave pure line method of corn breeding, which laid foundation for present day hybrid breeding. Pure line methods of maize breeding involve three steps. 
    
·    Large scale inbreeding to obtain many homozygous/nearly homozygous inbred lines. 
    
·    Testing the selected inbred lines in all possible crosses.
    
·    Practical utilization of inbred lines in seed production of single cross hybrids.

15.1. INTRODUCTION

Finger millet Eleusine indica (L.) is an Old World cereal grass commonly known as ‘finger millet’, is one of the staple food crop especially in India and Africa, which is widely grown in the arid regions of Asia and Africa and important minor millet grown in India.  Eleusine, the generic name, is obtained after the “Eleusine” the Greek Goddess of cereals and the common name finger millet is derived from the finger like branching of the panicle. It is also know by Goosegrass, Yardgrass, Wiregrass, Silver Crabgrass, Crowfoot Grass. It is commonly known as Finger millet in English, Kelvaragu in Tamil, Nachani in Marathi etc. Some Indian varieties of finger millet are Kempu ragi, Ragalli shivalli, Pichakaddi etc.  This crop is one among the hardiest crops which can with stand severe drought conditions and can also grow well under scanty rainfall condition. However with good irrigation facilities the yield of finger millet matches with crops like rice. Finger millet seeds remain free of pests and insects for a long duration extending up to 50 years hence serving as a food reserve in case of tough situations like famine.

17.1. INTRODUCTION

Yam bean is one of the adaptable, low-maintenance, and nutritious food crop grown in moderate soil. It has many synonyms, in India it is known as Mishrikand (Hindi), Keshar or Ram-kaseru or Shankalu (Bengali). The root crops produced by legumes have long recognized as important and the FAO (1979) has recommended them as a source of human nutrition. The tuber is rich in starch (15-20%), 3-4% sugar, and have considerable amount of protein (2-3%). The harvested crop keeps well for months under ambient temperature. Kale (2006) observed relatively high iron contents in storage roots (up to 130 mg/kg of storage root dry matter). It can also be used for alcohol production.

The crop is very hardy, resistant to common insect pests and diseases. Most important is that the crop is not grazed neither by goats nor cows. The crop grows well in hot-humid environment and requires long, warm frost-free growing season. A moist, light textural soil is preferred for production of tuberous roots. As a legume crop, it can be grown without nitrogen fertilizer. Under good growing condition its root nodules habour symbiotic colonies of nitrogen-fixing bacteria- Rhizobium spp. (Nielsen et al., 1998b). A season crop of yam beans can release as much as 53 tons of usable nitrogen per acre into the soil. Mycorrhyzae also associated with the crop, thus facilitating phosphorus uptake. Thus, yam bean is highly suited to the needs of small farmers, and from both an ecological and a socioeconomic perspective

Olericulture, a Latin word, is used to designate the science, culture and management of vegetable crops. In India, about more than fifty vegetable crops are grown in different parts, depending on their climatic requirement. A number of vegetables have similarity in their method of cultivation, which makes the package of practices followed by the farmers for their cultivation very complicated and brings about a lot of repetition. Whichever the method is adopted for the classification of vegetables can systematize the preparation and presentation of the material to some extent and can avoid the unnecessary duplication of some of the principles and methods of vegetable cultivation. In different vegetables, different plant parts are used as food in different forms and they belong to different botanical families with varying cultural and climatic requirements but common insect-pests and diseases along with their common control measures.

Various methods may be used to classify all the vegetable crops into different categories but no single method of classification would be useful to serve the purpose for different groups of scientists like taxonomists, botanists, physiologists, horticulturists, agronomists, and breeders. Under field conditions, the classification based on cultural practices has been proved the best adaptable and very useful for the growers. Vegetable crops can be classified in the following ways for the convenience of different groups of scientist and growers:

After attaining green revolution, nutritional security is of utmost importance in the current agricultural scenario. Vegetables play a key role in providing nutritional security in the country. They are important and readily available source of mineral nutrients and vitamins and play a vital role in the financial economy of the majority of small and marginal farmers. Further, these roles are becoming more transparent in the light of agriculture diversification as the vegetables have many agro-economic advantages and can fit into varying cropping systems under diversified conditions. After China, India is a leading vegetable producer but the productivity of vegetables per unit area is very low compared to other developed countries. Poor crop stand establishment is one of the factors responsible for low productivity. Yield and productivity can be improved by using advanced technology on the field preparation, optimum sowing conditions, correct nursery practices and planting methods.

Almost all the vegetable crops are propagated by seed, except a few. Crops are raised either by direct seeding in the field or by transplanting seedlings raised in nurseries. Direct seeding is the placement of seeds at desired depth into the final location where soil environment is ideal for optimum germination and crop stand establishment. On the other side, transplanting refers to removal of actively growing seedlings from one place to another with the purpose of having them continue their growth in the new location until harvest.

The vegetable crops like peas, beans, cowpea, okra, beet leaf, spinach, fenugreek, coriander, carrot, radish, turnip, beetroot, etc. are sown directly in the field, while tomato, eggplant, hot pepper, sweet pepper, onion, leek, sweet potato, cabbage, cauliflower, broccoli, Brussels sprout, kohlrabi, kale, lettuce, celery, parsley, rhubarb, squashes, etc. are first sown in the nursery beds where seedlings are raised and then transplanted in the main field. Both direct seeding and transplanting are practiced in most of the cucurbits like gourds, cucumber, melons and pumpkin.

The directly sown vegetable crops do not respond to transplanting because their embryonic roots do not produce lateral fibrous roots after uprooting unlike transplanted crops where numerous fibrous roots are generated, thus, making the plant to absorb more nutrients.

Global onion research connects crop domestication, genetic diversity, nutrition, therapeutics, production, breeding and post-harvest technology. Onion contains organosulphur compounds, quercetin derivatives and other phytochemicals associated with antimicrobial, antioxidant, cardioprotective and anticancer effects. Despite high global production, productivity differs substantially among countries, and storage losses remain a major economic concern. This chapter reviews global production trends, germplasm resources, breeding strategies, phytochemistry, therapeutic potential and emerging storage technologies. Landraces, cultivars and wild relatives provide valuable traits for yield, storability and stress resilience. Advanced treatments such as ozonation, cold plasma and irradiation demonstrate promise, although wider commercial adoption, economic validation and regulatory development remain necessary.

1. PLANT DOMESTICATION AND INTRODUCTION

Domestication is the process of bringing wild species under human management. Under domestciation, the crop species have changed considerably as compared to the wild species from which they originated.

Introduction
Understanding the concepts of technology transfer, licensing, and commercialization is crucial as it plays an important role in understanding how scientific discoveries leads to generation of new technologies further making them the impactful solutions that benefit industries and society. In the context of Indian HEIs, this especially important because a large volume of impactful research often remains underutilized due to limited commercialization channels. This chapter explains the terminology, essential components of technology transfer, outlines its significance for the innovation ecosystem. It also outlines the evolution of India’s technology transfer ecosystem, and emphasizes while understanding its potential to boost India’s economy, encourage entrepreneurship, and strengthen global competitiveness. From initial idea to a market-ready product is complex and multiphased process. The stepwise process is shown in Figure 1. It highlights a structured pathway consisting of five core phases: Idea/Concept, Technology development, Intellectual Property (IP) rights, Technology transfer, and Technology commercialisation.
Phase 1: Idea/Concept stage
This process of technology transfer starts with the Idea/Concept phase, where an invention is created. Each phase plays an important role in transforming raw scientific knowledge into innovative solutions that benefit society and generate economic value. In this phase breakthrough ideas emerge, within labs. Researchers explore and develop initial proof-of-concept or prototypes to validate their ideas. At this stage, the focus is primarily on knowledge creation rather than commercialization. This pathway of technology transition is summarized in Figure 1.

A TTO needs a planned budget of five years to sustain it in the long term. This involves budgeting the infrastructure, manpower, research, and outreach programs. The budgetary needs of a TTO will be based on the size and scope of the TTO and the maturity of the parent institution it caters to. The initial years will be focused on capacity development, the appointment of experts, and the establishment of processes of intellectual property management. The mature TTO will generate income through the returns of the licensing agreements and the collaborative efforts with the industry. Nevertheless, external funding through grants and government schemes plays a vital part, particularly in the initial years. The planned budget ensures long-term stability and development of the TTO.
9.1 Budgetary heads
9.1.1 Operational expenditure
Operational expenditure refers to the ongoing costs incurred by a TTO to maintain its day-to-day operations. This includes the cost of maintaining the office, including rent, power and utility bills, computer and network infrastructure, patent management cost, and administration charges. The filing and legal charges also fall within this category. The overheads will be a heavy burden if not planned with finances properly. A TTO has to be provided with a properly planned operational budget that covers the daily operational expenses. The operational expenses help the office perform effectively, sustain the employees, and effectively manage IP. The operational expenses that the budget normally covers include:

Technology transfer (TT) is entering a transformative phase shaped by globalization, digitization, and the growing role of start-ups in the innovation ecosystem. Traditional linear models of TT where inventions flowed from academic laboratories to industry through licensing are being replaced by dynamic, multi-directional, and collaborative frameworks. This chapter explores emerging trends that will define TT in the coming decades, including open innovation platforms, digital TT ecosystems powered by artificial intelligence (AI) and blockchain, the rise of entrepreneurial start-ups and spin-offs, internationalization of TT through cross-border collaborations, and sector-specific shifts driven by 5G, biotechnology, drones, and green energy. Drawing from global and Indian contexts, the chapter highlights how universities, governments, and industries can leverage these trends to build inclusive, resilient, and sustainable innovation ecosystems.
Three global shifts which will redefine TT
1. Digitization of knowledge: With AI, big data, and blockchain, knowledge and IP can be shared, tracked, and commercialized faster and more transparently.
2. Entrepreneurial ecosystems: Start-ups, incubators, and accelerators are replacing traditional firms as vehicles of commercialization, particularly in deep-tech and frontier technologies.
3. Globalization of innovation: Challenges such as pandemics, climate change, and food security require cross-border TT collaborations, making TT an instrument of both economic and geopolitical significance.

Nursery management is indeed a very important operation in successful growing of vegetables especially those, which are raised through seedlings in properly managed nursery beds. Raising nursery from seed provides an easy and convenient way to nourish tender young seedlings in a well-managed small and compact area. The nursery area can be conveniently protected from natural hazards, seed borne diseases and insect-pests and can be well managed economically. Some of the vegetable seeds are very costly, for which it is necessary to raise nursery in the most-optimum conditions. In areas where land holdings are small (in hills), nursery raising helps in making economical use of land for about one month and provides enough time to mature for previous crop, harvesting, threshing and land preparation for next crop. Most of the vegetable crops like cabbage, cauliflower, tomato, eggplant, sweet pepper, hot pepper, onion, celery, parsley, lettuce, etc. can successfully be raised through seed by growing them in the nursery and then transplanting in the field.

“A vegetable nursery is a place or an establishment for raising or handling young vegetable seedlings until they are ready for more permanent planting.”

Nursery can be maintained either for personal or commercial purpose, and each has its own advantages and disadvantages. Seedlings raised for own planting will be true to type, sound and healthy. On the other hand, seedlings purchased from outside may not be true to type, vigorous and healthy and may not arrive at destination in due course of time.

The collection of cones/fruits and seeds is the first step in the harvest, processing, and storage of seed in which man interacts with nature in determining ultimate seed quality. Successful collection, therefore, depends on understanding seed maturation and dispersal characteristics of each species, knowing local weather trends, and evaluating crop quality. Collection of propagating material is an expensive process and it is therefore also important that areas wherein cones and seeds are to be collected are evaluated to determine whether a sufficiently heavy crop to permit economic collection of seeds is present and whether the seed zone and elevation represented by the candidate area is appropriate for the production of seedlings needed in the reforestation program. Remember that properly collected, processed, and stored seeds may remain viable for a decade, so evaluation of seed needs may be projected well in advance of current harvest schedules through proper planning and organization of seed collection.
