5.1 PRODUCTION METHODS OR DIFFERENT TYPES OF PLANTS PRODUCED IN THE NURSERY

The different types of plants produced in the nursery include plants in plastic bags, bare-root plants, stumps, pseudo estacas, root trainers, copper coated trainers and jiffy pellets.

The most common production techniques may not always be the best. Bare-root plants and pseudo estacas are easy to transport to the field, but their survival and growth are usually very poor. Plastic bags are cheap and easily available, but they result in coiled roots and are heavy to carry to the field. Root trainers, copper coated trainers and jiffy pellets are alternative systems which may have higher initial costs for the nursery. However, the farmer will receive the benefit of fast growth and high survival in the field

Classifications of cropping systems

Depending on the resources and technology available, different types of cropping systems can be adopted on farms and which are as below.

Mono cropping /single cropping: Mono cropping refers to growing only one crop on a particular land year after year or practice of growing only one crop in a piece of land year after year. Example, growing only crops during kharif in rainfed areas and this is due to lack of irrigation facilities and crops depend on rainfall alone.

Azolla, a fresh water fem is a rich source of nitrogen especially for low land rice farming. It is found in rice paddies in many tropical countries like China, India, Korea, Philippines and Vietnam. The agronomic importance of Azolla lies in its ability to fix atmospheric nitrogen through the symbiotic association with a blue-green alga, Anabaena azolae. The symbiotic association can fix nitrogen proportional to its biomass produced. When Azolla is grown in paddy f ields and subsequently incorporated as green manure, the nitrogen contained within Azolla biomass is mineralized during the process of decomposition.

Azolla is a genus of small aquatic fern comprising 7 living and 25 fossil species, which is globally distributed. It occurs on still water ponds, lakes, swamps, lagoons and paddy fields in both tropical and temperate regions. Because of its rapid growth, high nitrogen percent and its ability to grow in stagnated waters, it has been used as organic manure in Vietnam and China for centuries. Its use in India and other countries is relatively recent. Azollla pinnata is native to India and widely distributed.

Introduction

Conventional agriculture is highly dependent on fossil fuel based mineral fertilizers to compensate for removal of plant nutrients by crops. Chemical fertilizers are not only in short supply but also are very costly. The preparation and use of organic manures are not being practiced in a scientific manner to harness the plant nutrients removed by plants, animals and humans.

The application of chemical fertilizers to soil alone and in an imbalanced way has resulted in deterioration of soil health and its quality. The use of chemical fertilizers has to be reduced to check the soil and water pollution and simultaneously the role of soil microorganisms has to be augmented by different ways such as greater use of biofertilizers. Moreover, the demand for organic food particularly both in developed and developing countries is on rise which opens up immense possibility to use organic manure and biofertilizers for production of foods grains, fruits, vegetables, spices, tea and coffee. Therefore, the production and the use of biofertilizers assumes greater significance and could be an excellent biological alternative to chemical fertilizers.

The solanaceous group of vegetables (tomato, eggplant, chili and bell peppers) generally take up large amounts of nutrients. The amount of nutrients they take up depends on the quantity of fruit and dry matter they produce, which in turn is influenced by a number of genetic and environmental variables. Tomato (Solanum lycopersicum L.) known as Tamatar in Hindi is one of the most popular and widely grown vegetables in the world ranking second in importance to potato in many countries. Tomato is widely grown in almost all parts of India and is adapted to wide range of soil and climate conditions. Tomato is consumed either as raw or cooked and is also very important crop for processing in the form of soups, juice, ketchup, puree, paste and powder. Tomato adds variety of colours and flavour to food.

Tomato is very well known for its nutritive value. Attractive red colour is due to lycopene pigment, pink and yellow colours are due to presence of anthocyanin and carotene pigments. Tomato is rich source of ascorbic acid, which varies from 15-31 mg per 100 g of fresh weight. Tomato also provides minerals like calcium, iron, magnesium, phosphorus and sodium. Tomato is also rich in medicinal value. The pulp and juice is digestible, promoter of gastric secretion and blood purifier. It is also considered to be intestinal antiseptic. It is one of the richest vegetables, which keeps our stomach and intestine in good condition.

Abstract

India is one among the major fruit producing countries of the world and offers opportunities of women empowerment through quality fruit production, planting material generation and production of value added products. There is a great opportunity to increase and improve the production of tropical, subtropical, and temperate fruits. Underutilized fruits also have a huge potential waiting to be exploited. This will only be possible with a concerted effort by researchers and growers, especially women to improve quality and increase production based on consumer demand and export potential. Women play significant role in fruit production activities. Unfortunately their access to knowledge, technology, finance, information, and training is minimal which hampers productivity of fruit crops. The mode of female participation in agricultural production varies with the land owning status of farm households. Their roles range from managers to landless labourers. In all farm production, women’s average contribution is estimated at 55 percent to 66 percent of the total labour with percentages much higher in certain regions. About 48 percent of India’s self-employed farmers are women. Thus, rural India is witnessing a process of transition which could be described as feminization of agriculture particularly fruit crop cultivation and their post harvest management. Women play an active role in various production and postproduction activities of horticultural crops. The number of women engaged in horticulture has increased continuously in the past two-three decades due to various factors such as migration of men to urban areas in search of non-farm income, increase in the demand of labour force in construction and other sectors. The data on the women involved in horticulture sector are scanty however the involvement of women in various operations of cultivation and post harvest handling and storage is very high because of entrepreneurial nature of horticulture. There is need to adopt collective and SHG approach to take women contributions to socio-economic significance. Thus horticulture, especially the pre-harvest and post harvest management of fruit crops have considerable employment avenues for women and make horticulture an effective subject of women empowerment.

Biofertilizer is still an unclear term. It can be easily found that biofertilizers are identified as plant extract, composted urban wastes, and various microbial mixtures with unidentified constituents, and chemical fertilizer formulations supplemented with organic compounds. Likewise, the scientific literature has a very open interpretation of the term biofertilizer representing everything from manures to plant extracts.  Quality control of biofertilizers involves several major aspects such as isolation and identification of various strains, screening of the pure isolated strains, fermentation and quality control and finished product.

India has the second largest concentration of tribal population after African continent. The tribal population of India is more than 8 per cent of the total population (Anonymous 2001). However, in Maharashtra it is over 9 per cent of the state population. Among the tribal community Bhil community is the largest tribal population in Maharashtra. They live in compact areas, which are generally hilly and undulating terrain. The Bhil are primarily farmers, though they are said to be hunters since the past. Poor condition of soil, small holdings, poor resources and economic condition, traditional methods of agriculture do not provide them a regular and continuous sustenance throughout the year as such they have to depend on other subsidiary sources of earning.

Most of the tribal communities have to live under a difficult economy; the ways of their livelihood are limited and work very hard to get a bare subsistence. Thus, the tribal children from their early age are burdened with a number of economic duties, obligations and they can hardly be spared for school. Proportion of dropout is also higher among tribal children. In fact most of the tribal youth and school going children participate in farming and looking after the economic demands of the family.

ICT refers to tools that facilitate production, transmission and processing of information. It includes the gadgets and processes to access, retrieve, store, organize, manipulate, produce, present and exchange information by electronic and automated means. According to UNESCO (2004), Information Communication Technology includes a range of technologies starting from radio, television, up to modern technologies like mobile phone, multimedia, internet, and satellite based communication systems. Modern information and communication technologies that have resulted from a breakthrough in information technology, when applied to conditions in rural areas, can help to disseminate information, improve farmers’ knowledge, increase their participation and share knowledge with others. Information Communication Technology (ICT) is one of the yardsticks to measure socio-economic development of the country and hence effective usage and management of ICTs tools is the pre-requisite for any development. Telephone is a powerful electronic device. The number of rural telephones was increased by approximately 35 per cent per annum (Jhunjhunwala and Ashok, 2005). This impressive growth in telecommunication sector is being utilized to provide information on demand to the farming community with the establishment of “Kissan Call Centers” (KCCs).  Kissan Call Centres were launched in January 2004 across the country to provide information services to the needy farmers and answer the queries made by them through telephone. In this context, a study was conducted to find out the profile of Kissan Call Centre users.

Abstract

In the present study, the village chicken rearing practices were documented in Kannur and Kozhikode districts of Kerala. A total of 128 native chicken farming households were surveyed. The system of management is extensive backyard type with the provision of shelter at night. Around 90% of the farmers had more than five years of continuous experience in village chicken farming. Majority (73.4%) of chicken present in this region was either reproduced within the household from earlier generations or added from the neighbourhoods of the same Panchayat. Most of the farmers (68.8%) consider that chickens are reared for both egg and meat; while, others (31.3%) deem that they are meant for eggs alone. As many as 87 % of the farmers cull the surplus males before one and half years of age. In contrast, majority of farmers (78.1%) do not cull female birds and usually maintain them till their death.

8.1. Terms and definitions

8.1.1. Extension program

A written statement of situation, objectives, problems and solutions which has been prepared on the basis of an adequate and systematic planning effort and which forms the basis of extension teaching activities in a specific area for a given period.

Programme planning and implementation constitute the core operational dimensions of community mobilization that translate vision, analysis, and community aspirations into concrete actions and systematic interventions capable of achieving meaningful and sustainable development outcomes. The transformation of community needs and opportunities into well-designed programmes requires sophisticated planning methodologies that can navigate complex social, economic, and political environments while building local ownership and capacity for long-term success and sustainability. Effective programme planning represents both an art and a science that combines analytical rigor with cultural sensitivity, technical expertise with participatory approaches, and strategic thinking with practical implementation considerations that must be balanced throughout the planning and execution process. The quality of programme planning significantly

Introduction

Precision farming, also known as precision agriculture, prescription farming, and site-specific farming, is grounded on the principle of managing fields based on their heterogeneity (Nowak 2021). In the past, crop management decisions were made for the entire field, treating it as a homogenous unit, despite significant variations in soil characteristics, weed infestations, and plant growth within a field (Nowak 2021). Precision agriculture integrates modern technology with past experience to manage farming on a grid-by-grid basis (Nowak 2021).

Project Implementation

Project Implementation is the process of putting a project plan into action. It takes place after the planning phase; planning phase includes key objectives, timeline and budget of the project. Execution includes organizing resources and assessing performance to guarantee the project stays within its anticipated scope and budget. It also involves handling any unforeseen issues in a way that keeps a project running smoothly.

Steps for Project Implementation

1. Assess the Project Plan: Before implementing the project, it is essential to create a plan that satisfies the expectations of the management, customers, and other stakeholders. The project manager must assess the project plan and guarantee that all team members comprehend the project and its requirements. The project manager must define the roles and the time required to complete each role. This step sets the standard for cooperation at work.

2. Execute the Plan: At this stage, the real work on the project begins. The project manager regularly discusses progress with his team. It measures progress along a timeline and tracks resource usage.

3. Make required Changes: Sometimes, during the implementation of the project, the manager has to make changes at the request of the customers or in other situations. Make these changes as needed, based on the design plan for solutions. Continue to interact with the team and ask questions to determine areas where they need more support.

4. Examine Project Data: It is crucial to gather and evaluate data throughout the execution phase of the project to assess the advancement of the project in comparison to its initial plan. Now, the day manager can use many project management software and information technology to collect and analyze real time data.

5. Assess the Feedback: After the conclusion of the project, it is crucial to gather feedback regarding the project outcomes from the clients, the project team and other stakeholders. This assists in determining the number of activities in the project that were executed as intended and aspects that require enhancement moving forward.

Project management in recent years has proliferated, reaching new heights of sophistication. It has emerged as a distinct area of management practices to meet the challenges of new economic environment, globalization process, rapid technological advancement, and quality concerns of the stakeholders. Project in general refers to a new endeavour with specific objective and varies so widely that it is very difficult to precisely define it or Project is a unique process, consist of a set of coordinated and controlled activities with start and finish dates, undertaken to achieve an objective confirming to specific requirements, including the constraints of time cost and resource.

Project management involves the use of knowledge, skills, tools, and techniques to design activities to fulfill project requirements. In other words, project management encompasses the skills, tools and management processes needed to successfully implement a project.

Project Management comprises

• Skill. Expert knowledge, skills and experience are necessary to reduce the risk level of a project and thereby enhance the likelihood of its success.

• A set of tools. Project managers use a variety of tools to improve their chances of success. Examples include document templates, records, planning software, modeling software, inspection checklists and inspection forms.

• Sequence of processes. Various Management methods and procedures are necessary to oversee and regulate the time, cost, quality and scope of projects. For example, time management, quality management, cost management, change management, problem management and risk management.

Project Management is adequate when or when should you use project man agement techniques

Project Report

A project report is a written document associated with every investment. It includes the details upon which the project was evaluated and deemed viable. It encompasses information regarding economic, technical, financial, management, and production elements. It assists the entrepreneur in understanding the interests and aids in securing loans from banks or financial institutions.

The project report provides comprehensive details on the necessary land and buildings, yearly production capacity, production methodology, machinery and equipment along with their costs and technical specifications, raw material needs, electricity and water requirements, labor needs, market costs of the project, production, financial analyses, and the financial viability of the project.

Contents of a Project Report

1. General Information: The project report needs to incorporate details regarding the industry relevant to the project. It ought to present information about the industry’s historical background, present condition, challenges, and future outlook. It must include details about the product to be created and the rationale behind the product selection if the proposed organization is a manufacturing entity. It should indicate the demand for the product in local, national, and international markets. It should distinctly outline the business opportunities and provide explanations for initiating the business.

It is not possible that every respondent is willing to and capable of giving honest and true response. Sometimes, it is practically not possible to make the respondent reveal about personal information, but true research requires true response. When direct stimuli fail to elicit true response, then we must use indirect and extractive methods to elicit the required response indirectly from the respondents, which further can be interpreted in the relevant format. This indirect and ambiguous stimulus based methods are known as projective methods. Projective methods are technique of data collection on the person, value, attitude, emotions and motives etc. by using a highly unstructured and ambiguous stimulus (Wilkening, Wilkening & Wilkening, 1973).

Climate change is a complex and dynamic phenomenon that has significant impacts on agriculture, especially in terms of uncertainty and variability. Agricultural dynamics refer to the various factors that affect agricultural production, including climate, soil, water availability, pests, and diseases, as well as market forces and government policies. Climate change has significant impacts on agricultural dynamics. Variations in temperature, patterns of rainfall, and occurrences of extreme weather can influence crop yields and livestock production in both beneficial and detrimental ways (UCAR, 2021). The effects of climate change on farming can differ based on the geographical location and the specific agricultural practices employed (Wikipedia Contributors, 2019). For example, in some areas, increased rainfall may lead to increased crop yields, while in other areas, droughts may lead to crop failures and loss of income for farmers. Additionally, rising temperatures can cause reduced crop yields and decreased quality of some crops.

Uncertainty is a term used to describe a situation where there is a lack of information, knowledge, or predictability about a particular outcome or event. In agricultural dynamics, uncertainty can refer to a range of factors that can affect the production, distribution, and consumption of agricultural products. One of the most significant sources of uncertainty in agriculture is the weather. The productivity of crops can be significantly influenced by weather conditions, including rainfall and temperature and farmers need to effectively adjust their agricultural practices to adapt to these changing weather patterns (Guntukulaand Goyari, 2020). For example, droughts or floods can reduce crop yields, while frost or hail can damage crops(Lamaoui et al., 2018).

Migration is a worldwide occurrence that can be attributed to various factors such as disparities in economic development, regional differences, and varying living standards among socio-economic groups. It is driven by both push and pull factors. Pull factors include opportunities for better employment and higher wages, while push factors encompass the lack of job prospects in underdeveloped areas, droughts, and scarcity conditions. Unlike the biological factors of mortality and fertility, which operate within a biological framework, migration is influenced by the desires of individuals. Although most migratory movements are intentional, there may be exceptional cases where this is not true. Therefore, migration is a response by individuals to economic, social, political, and demographic forces in their environment and serves as an important indicator of social change in society.

1. Introduction

Poultry industry in India stands out as a major success story. It’s phenomenal that India’s poultry production whichstarted justas a backyard venture before 1960s, has shaped up into a proven agribusiness, where its annual turnover exceeds Rs 30,000 crores. Current global ranking of India is that of number three, in terms of egg production (behind China [1st] and USA [2nd]), and of18th position in Broiler production. Today, Poultry is one of the fastest growing industries of the agricultural sector in India at present. The annual growth of broilers and egg production is 8-10% compared to 1-2% for production of agricultural crops [3].

Poultry production forms an important Agrarian Avenue providing valuable animal proteins for the fast-growing human population of the developing India, with promises of additional income to small and marginal farmers.Rural and backyard poultry farming is very common among landless and marginal farmer families in India and is a rewarding source of additional income. It involves low investment with high returns which can be easily operated by women, children and elder members of the farm families. Poor households generate good income through backyard poultry farming which provides meat and egg rich in protein and energy. Agriculture including animal husbandry provides 30-40% employment in terms of man/woman days in a year. Scarcity of land holdings, land fragmentation and seasonal agriculture aresome of the reasons that crop production only is unable to provide cent percent employment to the rural youths (men and women).

Abstract
The global population is projected to reach 9 billion by 2050, with rural youth (aged 15–34) in developing countries of Africa and Asia facing significant challenges like unemployment, poverty, and limited access to resources such as land, credit, and education. Despite agriculture's potential to provide livelihoods and contribute to 32% of global employment, rural youth are increasingly disengaged, perceiving farming as unattractive due to its image of drudgery and lack of profitability. Agri-preneurship, blending agriculture with entrepreneurial skills, offers a solution by fostering innovative, profitable farm businesses. Initiatives like India’s ARYA program and private efforts such as the Green Shoots Foundation promote skill development, encouraging youth to pursue agriculture through training, microfinance, and market linkages. Empowering rural youth with entrepreneurial competencies can enhance food security, reduce rural outmigration, and support sustainable development.

Pest and pathogen incidence is a natural occurrence that frequently goes unreported. However, they become a concern when their spectra expand and cause significant losses. Chemical pesticides are now commonly used in agricultural techniques to lessen the impact of such severe damages. Without a question, the use of chemical pesticides has put human health, ecological health, and sustainability at danger.

In recent years, rainfall pattern is changing and the sustainability of irrigated rice ecosystem is threatened by water crisis. Tanks are often not filling or partially filling due to insufficient rains. In order to safeguard the food security, it is necessary to preserve previous water resources and to utilize the limited water most efficiently. In this regard alternate ways of growing rice using minimum water must be explored. Farmers are adamant to grow paddy crop to meet their domestic needs of food and fodder. In such situation Jalasri method can became one of the alternative for paddy cultivation. The Jalasri method is an appropriate system aimed at reducing the cost of cultivation, saving irrigation water, besides increasing grain yield significantly. Earlier Jalasri method was popular as Madagascar method of paddy cultivation.

Plant nutrients are naturally components of the soil orchestrated by weathering processes and that the abundance of these metals in our soil environment now-a-days is due to numerous anthropogenic activities. In the environment, heavy metals are partitioned among the various environmental compartments such as water, soil, suspended solids and biota. Processes such as dilution, dispersion, sedimentation, adsorption and desorption govern their distribution. They also exist in colloidal ionic particulate and dissolved phases,  have a high affinity for humic acids, organic colloids and oxides coated with organic matter. The soluble forms are generally ions or unionised organo metallic chelates or complexes. The solubility of metals in soil and groundwater is predominantly controlled by pH, amount of metal, cation exchange capacity, organic carbon content, the oxidation state of the mineral components and the redox potential of the system.

Physical Properties of Soil

Physical properties of soil have many important roles in the crop production. The basic requirements for germination, seedling emergence and root development are adequate moisture and aeration, optimum temperature and absence of mechanical hindrance. After germination the further development of plant is also governed by physical conditions of soil. Soil texture, soil structure, soil density, soil consistence, soil water, soil air, soil temperature and soil colour are main physical properties of soils also affecting mechanical behaviour of soils. These are described here.

1. Soil Texture

The weathering divides larger particles of rocks and minerals in to the smaller ones. This process goes continuously. Thus, particles of different sizes ranging from large fragments of rocks to the very fine clay minerals are found in soil. However, for texture particles less than 2mm diameter is considered. The relative amount of these particles indicates the soil type also. Such as sandy soils contain more amounts of coarse particles i.e., sand and clayey soils are rich in fine particles. The rock and mineral particles having diameter less than 2.0 mm and come between specifies size are called as soil separates. International society of soil science (ISSS) and United States Department of Agriculture (USDA) systems are Generally, followed to classify the soil separates. This classification is given in table 3.1.

Nano-material possess unique properties such as dimension, shape, specific surface area, surface mass ratio etc., that are highly influenced by the mechanical and physical properties. It is pertinent to understand the basic physical properties of nano-materials in order to apply them in a wide array of functions. In this context, this chapter is devoted to provide basic information on physical, mechanical and photo-luminescence properties of nano-materials.

Nano-materials are to be extensively studied and characterized prior to their application in material science, biological science, electrical and electronics. In addition to the basic physical properties of the nano-materials, other characteristics such as paramagnetism, ferromagnetism, supermagnetism, optical properties, quantum size effects and electrical properties have to be studied. With a view to provide the fundamental information on these aspects this chapter is dedicated.

In India rice is cultivated under two land situations. In uplands, rice is grown under rainfed conditions and the yield is normally low. In medium or low land conditions rice is grown under wet condition where plenty of rain water or irrigation water is available. Here an intensive tillage is practiced in wet to create a soft puddle condition and then paddy is transplanted. Land submergence is thus an essential condition for successful rice cultivation.

Rice soils are not necessarily soils with water at or near the surface. Many soils have a fairly deep water table, but their surface is kept under submergence maintaining depth of 3-5 cm water. This condition is maintained either by puddling when wet or by having a compacted layer in the sub surface.

A rice soil is characterized by reducing conditions, when it is cropped with rice during wet season and oxidizing conditions during dry season, when the land remained fallow or planted with dry season crops if, irrigation water is available.

The atmosphere near Earth’s surface, often referred to as the boundary layer, exhibits unique properties influenced by the interaction between the surface and the atmosphere. These properties are crucial for understanding weather patterns, climate, and various environmental processes. Ancient Indians use to worship five natural elements i.e. earth, water, air, energy and the sky. Perhaps they were aware of the interactive effects and processes between these 5 elements that govern life on earth. In a sense, meteorology itself is a science based on interactive effects of these natural elements. Microclimatology is all about the effect of the interactions between these 5 elements on life over the earth. For a beginner of microclimatology, it is important to understand the properties of the atmosphere near the earth’s surface and get familiar with the concept and terminology used to describe/quantify the physical processes taking place between the lower layers of the atmosphere and the earth’s surface.
2.1. Energy
The major source of energy in the earth atmosphere system is solar energy (Fig.2.1). The outer surface of the sun is very hot and its temperature is estimated to be around 6000°Kelvin (symbol K).
The Kelvin is the base unit of temperature in the international system of units (SI). The Kelvin scale is the absolute temperature scale that begins at the lowest possible temperature that can be attained (absolute zero) taken as 0 degree K. The magnitude or value of each degree of temperature in the Centigrade scale and Kelvin scale is same. The temperature measured in centigrade scale can be converted to Kelvin scale by adding 273.15. The sun emits heat energy in the form of solar radiation. As the solar radiation passes through the atmosphere, it gets partly depleted before reaching the earth’s surface. The processes through which the solar radiation gets depleted in the

1. Introduction Proso millet (Panicum miliaceum (L.) belongs to the grass family Paniceae. It is a perennial cropthat grows in summer each year as late-seeded summer crop (Figure 1). Its origin can be traced back to at least 2000 B.C. when it was said to be grown in the Central European regions. Proso millet plant thrives in dry areas such as Africa, Central Russia, Manchuria, Middle East and Northern India and North America’s Great Plains. Proso millet was introduced to Canada in the 17th century and used sparingly as a feed crop in the early 1900s (Rajasekaran and Francis, 2021). This is a low-demand crop and is utilised in organic farming systems across Europe and as an intercrop in the United States. Its shallow root system and resistance to atrazine residue make it a great intercrop between two crops that need a lot of water and pesticides. The last crop’s stubbles entrap more heat into the soil which promotes faster and earlier growth of millet. Hence, it can help to evade summer drought and achieve continual crop rotation (Kalinova and Moudry, 2006). It is an erect herbaceous annual crop with a lot of tillering. Its plant can reach a height of 45-100 centimetres. The stem is thin, with prominently enlarged nodes. The roots are thin and fibrous.

1.1 Introduction Among the C4 grasses known as panicoids (subfamily: panicoideae), which also includes nutrient-rich cereals like millets and sorghum as well as commercially valuable crops like switchgrass, napier grass, and guinea grass, are bioenergy feedstocks like sugarcane and miscanthus. Among all, millets overpowered others in terms of biotic/abiotic stress resilience, resource sustainability as well as nutritional benefits. Minor millets, often known as nutritional cereals, are a type of small-seeded grains that are members of the Poaceae family. Up to 35 kinds of grass from 20 genera are well-known for being minor millets. Finger millet, foxtail, proso millet, barnyard millet, kodo millet, and little millet are the most significant small millets that are grown worldwide. India is the leading producer and consumer of millet crops and their products. The total area of small millets in India is around 1.63 m ha, with a production of 1.82 m tones during the year 2016- 17 (Annual progress report 2018-19, ICAR-AICRP on small millets).

SUMMARY

Green manuring is the practice of growing lush plants on the site into which organic matter directly incorporate to the soil while it is still fresh. Green manures, often known as cover crops, are plants which are grown to improve the structure and nutrient content of the soil. They are a cheap alternative to artificial fertilizers and an eco-friendly input for organic farming and can be used to complement animal manures. Growing a green manure is not the same as simply growing a legume crop, such as beans, in a rotation. Green manures are usually dug into the soil when the plants are still young, before they produce any crop and often before they flower. They are grown for their green leafy material which is high in nutrients and protects the soil. It is basically a holistic management system, which promotes and improves the health of the agro-ecosystem related to biodiversity, nutrient biocycles, soil microbial and biochemical activities.

Introduction

Persistent income from agriculture is most important for sustaining the farming sector. Conservation agriculture (CA) is a resource-saving agricultural production system that aims to achieve production intensification and high yields while enhancing the natural resource base through compliance with three interrelated principles, along with other good production practices of plant nutrition and pest management (Abrol and Sangar, 2006). Conservation agriculture is largely promoted as one of the few win–win technologies affordable to farmers, in the sense that potentially it improves farmers’ yields (in the long term) at the same time conserving the environment. CA is described by FAO (http://www.fao.org.ag/ca) as a concept for resource saving agricultural crop production which is based on enhancing the natural and biological processes above and below the ground. As per FAO definition CA is to a.) Achieve acceptable profits, b.) High and sustained production levels, and c.) Conserve the environment. It aims at reversing the process of degradation inherent to the conventional agricultural practices like intensive agriculture, burning/removal of crop residues. Shifting from tillage-based agriculture to no-tillage CA systems removes unsustainable elements in the current tillage based systems and replaces them with CA elements that make the production systems profitable and ecologically sustainable. Conservation agriculture offers an opportunity for arresting and reversing the downward spiral of resource degradation, decreasing cultivation costs and making agriculture more resource – use-efficient, competitive and sustainable.

Abstract
Milk, recognized globally as a complete food, is rich in essential nutrients like calcium, amino acids, and bioactive compounds, offering numerous health benefits such as antimicrobial, antihypertensive, and anti-carcinogenic properties. India, the world’s largest milk producer with 170 million tonnes annually (20% of global production), is witnessing rapid growth in its dairy industry, projected to reach a market value of Rs. 10 trillion by 2025. The sector, driven by modernization, cooperatives, and increasing consumer demand for value-added products like ghee, cheese, and probiotics, presents vast entrepreneurial opportunities in dairy farming, processing, retail, and machinery manufacturing. However, challenges such as poor hygiene, inadequate cold chains, and livestock health issues hinder quality and scalability. Emerging processing technologies and adherence to FSSAI regulations can enhance product quality and market potential, making dairy enterprises a cornerstone of India’s food industry and rural economy.

Agroforestry is a collective name for land-use systems and technologies in which woody perennials including trees, shrubs, bamboos etc. are deliberately combined on the same land-management unit with herbaceous crops or animals either in some form of spatial arrangement or temporal sequence. In agroforestry system there are both ecological and economic interactions amongst the different components (Lundgren and Raintree, 1982). The origin of agroforestry practices, i.e. growing trees with food crops and grasses, is believed to have been during Vedic era (Ancient period, 1000 B.C.), the agro-forestry as a science is introduced only recently. Agro-forestry is the science of designing and developing integrated, self-sustainable, land-management systems that involves the introduction and retention of woody components such as trees, shrubs, bamboos, canes and palms along with agricultural crops including pastures or animals, simultaneously or sequentially on the same unit of land and time, to satisfy the ecological as well as socio-economic needs of people. This practice of growing trees and arable crops together on the same piece of land is an age-old practice with the dry land farmers. Agroforestry results in multiple products, increases income, reduces runoff and soil loss, utilizes off-season rainfall and radiation and gives stability to dry land agriculture. Further it makes the future generation farmers to inherit not only the land of their predecessors, but also the wealth of standing biomass of trees.

National Forest Policy (1988) has set a goal that 33% of the country’s geographical area should be under forest and tree cover. Under Tenth Five Year Plan, the Government of India has set a target to increase the country’s forest cover up to 25%. According to the latest report of Forest Survey of India (2013), the forest cover in the country is 697,898 km², constituting 21.23% of its total geographical area. Out of this, dense forest constitutes 12.24 % and open forest 8.99 %. The only solution to achieve these targets is through the practice of agroforestry. Therefore, in the quest of optimising productivity, the multi-tier system came into existence.

Since the 1960s, the world population has doubled from three to seven billion, and this trend will persist in the coming decades. Because of this rapid expansion, a massive increase in crop production is required to meet the food and energy demands of future generations. Potassium is the third important plant nutrient after nitrogen and phosphorous. It is seventh most abundant element in the lithosphere. Being chemically active metal, it is never found in its pure elemental state in nature. Potassium (K) plays a particularly crucial role in a number of physiological processes vital to growth, yield, quality, and stress resistance of all crops. The K content of Indian soils varies from less than 0.5–3.0%. The average total potassium content of those soils is 1.52% (Mengel and Kirkby 1987).

The role of mechanization has of late earned considerable significance in Indian agrarian sector following the unprecedented hike in labour cost, migration of agricultural labour to the urban localities for better remuneration and most importantly, the rising concern of rural youth today for more comfort as well as social dignity and status. Furthermore, mechanization has been extremely supportive to enhance the efficacy of the vital inputs to agriculture such as high yielding seeds, fertilizer, water, pesticides etc resulting in higher production and productivity. One more significant contribution of mechanization is timely completion of various operations with qualitative and quantitative competence apart from reduction in drudgery; thus motivates the farmer to dare for higher initial investments in anticipation of rich dividends over a period of time.

1. Introduction
The environment and human health are seriously threatened by contaminants,both organic and inorganic, whose prevalence and persistence have beensteadily rising in recent years. In addition to propelling economic and scientificadvancement, the industrial revolutions of the 19th and 20th centuries have alsoled to widespread pollution (Wuana & Okieimen, 2011; Singh et al., 2013).Industrial activity has increased trace metal concentrations in the environment,with sediments acting as key sources and reservoirs for heavy metals. Thesemetals build up in soils and aquatic bodies as a result of scouring, erosion,rainfallleaching, wastewater discharge, and atmospheric deposition (AlonsoCastillo et al., 2013). Additionally, toxic contaminants like phenols, industrialeffluents, domestic wastewater, agricultural runoff, fly ash, fertilizers, andwaste from insecticides, pesticides, and pharmaceutical industries infiltratethe environment and food chain via mechanisms such as bioaccumulation,biomagnification, and bioconcentration (Arora & Bae, 2014; Azubuike et al.,2016).

Introduction

Natural resources, especially those of soil, water, plant and animal diversity, vegetation cover, renewable energy resources, climate, and ecosystem services are fundamental for the structure and function of agricultural systems and for social and environmental sustainability, in support of life on earth. Historically the path of global agricultural development has been narrowly focused on increased productivity rather than on a more holistic integration of natural resource management with food and nutritional security. A holistic, or system-oriented approach, is preferable because it can address the issues associated with the complexity of food and other production systems in different ecologies, locations and cultures. Modern agriculture largely depends on the use of fossil fuel-based inputs, such as chemical fertilizers, pesticides, herbicides and energy intensive farm machinery. While the applications of such high input technologies have undoubtedly increased production and labour efficiency. There is a growing concern over their adverse effect on soil productivity and environmental quality which is emerging to recognize that the farmer has a great social responsibility as a land owner than merely agribusiness considerations. Therefore, there is need to develop agricultural techniques that are ecologically sound, economically viable, and socially responsible. Sustainable agriculture in the context of development helps to achieve production efficiency, protect ecosystem functions, enhance resilience to climate change, ensure healthy communities, satisfies basic needs and ensures optimum use/conservation of natural resources. Organic/biodynamic farming is among the various types of sustainable agriculture. Traditionally these methods has been playing very vital role in the conservation of natural resources in terms of soil health sustenance, environmental protection, food safety, waste recycling, biodiversity conservation with an economically viable approach. The chapter discusses the role of organic/biodynamic agriculture in natural resource conservation.

Abstract

Northeast is famous for its rich bio-diversity and Himalayan scenic beauty. Society is mainly agricultural based but the crop productivity is low in comparison to all India average. Major reasons are lacking of a). Improved cultivation technology at village or at farmers level, b). Agricultural inputs like high yielding seeds, chemical fertilizers and pesticides due to poor infrastructural facility, c). Land tenure system, etc. The agro climatic condition is very suitable to grow different types of vegetables round the year. Hilly areas offer a scope to grow certain vegetables as off-season vegetables and earn a high price. Northeast soils need application of nutrients for improving its productivity. Century old Jhoom cultivation technique, high soil erosions in hilly areas and regular floods in plains also play a vital role in developing reluctance among farmers in using costly chemical fertilizers. Profuse growth of vegetations e.g. grasses; weeds, jungles, etc. are noticed due to regular rainfall throughout northeast. Peoples usually burn these during clearing their fields and backyards for cultivation. These can be converted to good quality compost using vermicomposting technique and added to field for cultivation of different crops substituting chemical fertilizers. Experiments on cabbage, cauliflower, French bean, okra, onion and tomato showed that yield increased considerably with the application of compost in field.

India has made a considerable progress during the last three decades in horticulture production in India producing 300.6 million tonnes of horticultural produce from 24.85 million hectares in 2016-17. The average productivity of different horticultural crops is quite low as compared to the best yields at national and world level, indicating the scope to enhance the yield in different horticultural crops by many fold along with its quality specially in vegetables. Unlike vegetables, flower cultivation is growing at a very fast speed and registered a marked growth along with employment generation through protected cultivation. According to NHB (National Horticulture Board), during the year 2014-15 the area under floriculture production in India was 248.51 thousand hectares with a production of 1,658 thousand tonnes loose flowers and 484 thousand tonnes cut flowers. However, India’s total export of floriculture was Rs. 548.74 crores/ 82.05 USD Millions in 2016-17. This is because of an appealing gap between potential yield and the actual yield of various vegetable crops. In many vegetable crops, the yields realized are even less than 50 % of their potential yield. Due to fluctuating market prices and poor storage infrastructure available for horticultural crops, farmers are not able to get their production cost. Though, there are some crops, fetches high prices during off-season. Several biotic and abiotic stresses are major factors, responsible for low productivity and poor quality in several horticultural crops under their open field cultivation during rainy and post rainy season more specifically, in vegetables. The increasing demand of off-season and high quality vegetables in various markets of the big cities has drawn the attention of the vegetable growers for diversification from traditional system.
