In recent years, there is gradual realization of the role of women in the field of agriculture & allied areas. Besides domestic work, they are involved in various types of field works relating to production of crops, milk, fish meat, egg, mushrooms & honey bee and other material. Employees in agriculture sector of the country, contributes nearby 80% of all economically active women (Bhatt, 2013). Therefore, rural India is now going through a process of “Feminization of Agriculture”.

Women are critical to the well-being of farm households. Besides child bearing and rearing, women are expected to prepare all meals, maintain the household jobs and assist in crop and animal production. Perhaps, ironically, it is because women who have so many responsibilities that they have been over-looked by agriculturalists and policy makers–it has been more convenient to label men as farmers and women as child raisers and cooks. Rural women form the most important productive work force in the economy of majority of the developing nations including India.

In spite of several efforts there still exists gender gap in the field of agriculture and allied areas. Closing the gender gap is not only the right thing to do; it is the smart thing to do for improved agriculture and food security for all. This was a key message for family farming interventions to close the gender gap.

World wide women play a major role in agriculture; including fisheries, forestry and livestock production. The nature and extent of their involvement is different in various agro production systems. Their role is diversified from management to landless labourer. In overall farm production, on an average women’s contribution is estimated at 55 to 66 per cent of the total labour (Singh, 2013).

Learning Management Systems (LMSs) have become central to digital education by providing platforms for content delivery, communication, assessment, learner tracking, and academic administration. Integrating Generative AI into these systems can transform conventional LMS environments into more intelligent, adaptive, and responsive learning ecosystems. This chapter examines the integration of GenAI with LMS platforms and other educational technologies to support personalized instruction, automated content generation, intelligent assessment, student support, and learning analytics. AI can generate explanations, quizzes, summaries, learning activities, and feedback while using learner-performance information to recommend individualized pathways. Integration with digital whiteboards, productivity platforms, chatbots, interactive content, and other EdTech tools can provide students with immediate assistance and multiple explanations of difficult concepts. For educators, these systems can support course design, assessment development, progress monitoring, and instructional decision-making. However, implementation involves technical challenges such as API compatibility, computing requirements, real-time data processing, legacy-system integration, infrastructure limitations, and shortage of skilled personnel. Regulatory issues involving privacy, intellectual property, misinformation, bias, and liability must also be addressed. Successful LMS integration therefore requires robust infrastructure, governance, interoperability, human oversight, and continuous evaluation.

Plant diseases caused by variety of pathogens pose a serious challenge and economic threats to various agricultural crops all around the world. It has been evidenced that despite wide use of chemical pesticides in crop production, the losses due to pests and diseases are significant. Phytonematodes are one of the major groups of organisms that live in diverse habitat and continue to challenge variety of agricultural crops all around the world. Since early times the major agricultural crops have been plagued by these noxious nematodes that feed on various plant parts viz. roots, rhizome, sucker, tubers, seedlings, stem, leaves, buds, crowns and cause damage worth more than 100 billion dollars annually. The major crops severely affected by these pests are, vegetables, fruits, sugarcane, sugar beet, cotton, oil seed, pulses, tobacco, tea, coffee, cereals, spices, medicinal and aromatic plants.

Introduction

Organic farming per se is not a new concept rather is an age old practice of cultivation crops without synthetics. However, in modern usage it is a type of farming without synthetics but at the same time taking advantage of all the modern agriculture technologies like soil testing, nutrient management, ecofriendly pest management, etc. developing and developed world have different incentives for taking up organic farming. Growing health consciousness among the people of developed world is the prime motive behind interest in organic farming. However, conversion of “by default” organic agriculture into “certified organic” is perspective in the developing world so that farmers get price premium. Whatever the case may be, the area under organic farming as well as demand for organic food/product is increasing both in developing as well as in the developed world.

Organic production is a systems approach. Although many aspects of vegetable production remain the same in both “organic” and “non-organic” or “conventional” systems, there are differences. The major components of production which differ between these two systems include transplant production, soil fertility management, and insect, disease, and weed management. “Organic” usually refers to a crop management system that promotes biodiversity, biological cycles, and soil biological activity. Organic production concentrates on natural processes and how to manage them. Other materials and products are additions to, not replacements for, management. An organic system takes time to develop. It may be achieved in stages, for example by starting with organic soil amendments and other soil improving procedures. Then, try biological control of pests, some companion plants, etc. Eventually, the entire system will be changed. It will take years to convert to a healthy organic system.

Due to increase in population, rapid urbanization, industrialization and shrinking land holdings, there is tremendous pressure on availability of land resources for agriculture, which results in decreased arable land area year after year. The huge gap between present production and future requirements necessitates intensive vegetable production and availability at affordable prices. Vegetable production can be enhanced either by increasing productivity, use of improved cultivars and ago-techniques, bringing additional land under vegetable crops or by promotion of protected cultivation. By adopting protected cultivation, year round availability of quality produces both for domestic use and export can be assured.

Several biotic and abiotic stresses are the major factors responsible for low productivity and poor quality in large number of vegetable crops under open field cultivation more specifically during rainy and post rainy season. The increasing demand of off-season and high quality vegetables in various markets of the big cities had call the attention of the vegetable growers for diversification from traditional ways of vegetable cultivation to modern methods of vegetables cultivation in an agri-business entrepreneurial models. Under the new era of FDI (Foreign Direct Investment) in retail these kinds of models are having high potential for betterment of the farmers opting for quality and offseason vegetable cultivation through protected cultivation. Protected cultivation structures are useful for combating both biotic and abiotic stresses that limits the productivity and quality of vegetable crops. This requires careful planning, attention and details about timing of production and moreover, harvest time to coincide with high market prices, choice of varieties adopted to the off season environments, and able to produce economical yields of high quality produce etc.

Data-centric artificial intelligence has transformed medical imaging, clinical prediction and electronic health-record analysis, but purely data-driven models face limitations involving generalization, bias, privacy and interpretability. This chapter examines the transition toward knowledge-aware and hybrid healthcare systems that combine machine learning with clinical knowledge, ontologies and knowledge graphs. It discusses explainable AI, clinical reasoning and the integration of structured knowledge into intelligent decision support. Applications include acute-care support, precision medicine, genomic oncology and population-health management. Ethical issues, regulatory compliance, fairness and privacy-preserving technologies are also considered. Future directions include quantum computing, large language models, multimodal integration and equity-focused healthcare-system development.

Introduction

Rice is the staple food for over half the world’s population. China and India alone account for ~50% of the rice grown and consumed. Rice provides up to 50% of the dietary caloric supply for millions living in poverty in Asia and is, therefore, critical for food security. Globally, share of Asia continent in rice production is more than 90% followed by America (5.2%), Africa (3.4%) and Europe (0.6%). It is becoming an important food staple in both Latin America and Africa. Record increases in rice production have been observed since the start of the ‘Green Revolution’. However, rice remains one of the most protected food commodities in world trade. Rice is a poor source of vitamins and minerals, and losses occur during the milling process. Populations that subsist on rice are at high risk of vitamin and mineral deficiency.

The Indian population of 1.32 billion is projected to reach 1.53 billion by 2030 A.D. Goyal and Singh (2002) estimated a demand of 146 million tonnes of rice (taken as 50% of total cereals) by the year 2030. On the other end of the scale, 3^rd projection puts rice demand to be 156 million tonnes by 2030 (ICAR, 2010). To meet this, it is immensely necessary to increase the productivity levels without adversely affecting the natural resource base. Achievement of the targeted production would be an uphill task in the coming decades with the shrinking natural resource base, deteriorating soil health and soil productivity, declining input use efficiency, plateauing of yields in irrigated ecologies and lack of a major yield breakthrough in rainfed ecologies. Further, slowdown in the growth rate of cereal production and growing population pressure have emerged as formidable challenges for the future food and nutritional security in India. These challenges will be more extreme under emerging situations of natural resource degradation, high energy demands, volatile markets and risks associated with global climate change (Jat et al., 2016; Lal, 2016). Since, rice is the staple food for our country’s food security primarily depends on this wonderful crop. Globally rice is cultivated now in 167 million ha with annual production of around 769 million tonnes (499.3 million tonnes, milled rice) of rough rice and average productivity of 4.6 tonnes/ha (3.62 t/ha, milled rice) of rough rice (FAO STAT, 2017). In Asian countries, >90% of the rice is produced and consumed. The other continents in which rice is grown are Africa (7.78% of the global area), South America (6.4%) and North America (1.4%).

Composting means decomposing organic wastes. It is a safe, non-polluting and microbiological method for disposal and recycle of organic wastes by converting those to balanced plant food materials, commonly known as compost, the organic fertilizer. In other words, the mineralization and partial humifi cation of organic materials by the action of microorganisms under suitable condition is called composting (Figure 6.1). The organic wastes undergo different physical and chemical changes with the help of microbes like bacteria, fungi, actinomycetes, etc. During composting the population of pathogenic microorganism reduces while that of benefi cial microorganism increases.

I. Rock Phosphate

Rock phosphate is natural source of phosphorus. It occurs as natural deposits of rock in Morocco, U.S.A., Egypt, Poland, Russia, Tunisia, Algeria, Brazil, Nauru and some Islands in the Pacific and the Indian ocean. It contains 20 to 35 percent phosphoric acid (P2 O5 ) but this phosphorus is in insoluble form. In India, some of rock phosphates occur in Udaipur and Jaisalmer districts (Rajasthan), Purulia (West Bengal), Singhbhum (Zharkhand) and Mussorie (Uttrakhand). Most of these phosphates are classified as low grade phosphate since its phosphoric acid content is less than 20-25%. The total reserve of low grade rock phosphate is estimated to be around 165 million tonnes of which nearly 70 million are reported to occur in Rajasthan. The other economically viable deposits are in Mussorie (Uttarakhand), Jhabua district (Madhya Pradesh), Singhbhum (Zharkhand) Kasipatnam (Andhra Pradesh) and Purulia district (West Bengal). Rock phosphate is the basic raw material for manufacture of superphosphate and other kind of phosphatic fertilizers. It is reported above that India has mostly low grade rock phosphate. Hence India has to spent huge amounts of foreign exchange to import high grade rock phosphate containing around 32-35%, P2 O5 for manufacture of phosphatic fertilizers.

Tuber crops are rated as one of the richest sources of energy, besides being a treasure house of vitamins and minerals. The highest rate of dry matter production per day per unit area makes tuber crops important in the food economy, especially in meeting rural feed security. The tuber crop produce can also be processed into various food products to suit the taste and need of the urban, semi-urban and rural folk as well. Better post harvest management and diversification for production of value added products is one of the dependable methods to make tuber crops lucrative to both farmers and entrepreneurs.

India has the highest livestock population in the world with 50% of the buffaloes and 20% of the world’s cattle population, most of which are milch cows and milch buffaloes. The dairy industry in our country is considered as one of the most successful development programmes in the post-Independence period. In the year 2006-07the total milk production in the country was over 94.6 million tonnes with a per capita availability of 229 gm. per day. The industry had been recording an annual growth of 4% during the period 1993-2005, which is almost 3 times the average growth rate of the dairy industry in the world. Milk processing in India is around 35%, of which the organized dairy industry account for 13% of the milk produced, while the rest of the milk is either consumed at farm level, or sold as fresh, non-pasteurized milk through unorganized channels. Dairy Cooperatives account for the major share of processed liquid milk marketed in the India. Milk is processed and marketed by 170 Milk Producers’ Cooperative Unions, which federate into 15 State Cooperative Milk Marketing Federations. Over the years, several brands have been created by cooperatives like Amul (GCMMF), Vijaya (AP), Verka (Punjab), Saras (Rajasthan). Nandini (Karnataka), Milma (Kerala) and Gokul (Kolhapur). Uttar Pradesh, Punjab, Haryana, Rajasthan, Gujarat, Maharashtra, Andhra Pradesh, Karnataka and Tamil Nadu are the milk surplus states in India.

Introduction

The green revolution is exemplified by too much adoption of high soil disturbance, modern varieties, energy exhaustive technologies, high amount of capital investment and simplification of farming systems (Meeus, 1993), resulting in uniform and featureless landscapes (Nassauer and Westmacott, 1987) in the most intensively farmed arable areas. In post-green revolution epoch, we had experienced a period of remarkable escalation in food productivity, despite rising land values and increasing land scarcity. Farmers from both developing and developed countries get exposed to several production constraints for achieving a sustainable, cost-effective and assured return from their field. Depending upon the circumstances and the scale of farm activities, farmers face varying degrees of climate risk, biotic invasion, and economic uncertainty. Thus, from the context of economical ambiguities, volatile food prices, social pressure to buffer ups and downs of agricultural production and achieving food security for ever growing population and curtailing poverty, farmers must be equipped with novel cultural practices to achieve a sustainable and assured cost-effective grain production. Research experiments throughout the globe found that the principal indicators for unsustainability of agricultural systems are: (1) intensive tillage induced decrement of soil organic matter (OM), structural degradation of soil, accelerated water and wind erosion, reduced water infiltration rates, surface sealing and crusting, soil compaction, (2) insufficient return of organic materials into soil, and (3) monocropping.

There are many distribution networks which an organization may use depending upon the nature and usage of the product. Generally, there are two types of distribution networks which are being widely used the first is direct selling to the customer and the second is to have intermediaries in between which ensures that the product is available to the final consumer. In this indirect method the company is not in direct touch with the customer and this gap is filled by the middleman. The middleman not only provides the product to the customer but he also provides continuous feedback to the organization about the product and market demands. 

Abstract

The geochemical signature and vulnerability of groundwater of the East Coastal aquifers of  India from Pondicherry to Nagapattinam were determined. The coastal aquifers are fragile and this situation becomes more intense in aquifer systems like that of the Pondicherry to Nagapattinam region. A total of 136 water samples were collected during pre and post monsoon of 2008 and 2009 respectively. Out of which 45 samples for each pre and post monsoon from shallow groundwater and 23 samples for each pre and post monsoon from deeper groundwater.. The samples collected were analysed for major, minor cations and anions. Selected samples were also analysed for stable isotopes (d¹⁸O and dD). The analysed samples were studied for; their utility for different purpose, the nature of the geochemical classification, their variations in ion ratios, extent of sea water intrusion and the percentage of mixing, The study reveals that chief mechanism controlling shallow groundwater is the salts precipitated in the pore spaces during the Pre monsoon were leached and dissolved during the subsequent monsoon apart from sea water intrusion. Southern part of the study area  is more vulnerable than the Northern part of the study area.

The Para rubber tree (Hevea brasiliensis) is the most important commercial source of natural rubber, a strategic raw material. Rubber is an indispensable commodity used in the manufacture of over 50,000 products worldwide. This crop has therefore emerged as a key plantation species in various countries. The global area under rubber  cultivation is about 9.6 million hectares producing 9.2 million tones annually (IRSG, 2014). Among the major natural rubber producing countries, India occupies 4th position in terms of production with 0.91 million tones and more significantly the first position in average productivity of 1823 kg/ha/year. The major rubber producing countries are Thailand, Indonesia, India, Malaysia, Vietnam and Sri Lanka. Rubber is also commercially cultivated in Philippines, Nigeria, Cameroon, Cote de Ivoire, Liberia, Brazil, Cambodia, Nigeria, Cameroon, Guatemala, Myanmar, Mexico, China, Ghana, Democratic Republic of Congo, Gabon, and Papua New Guinea.Increase in production and improving productivity of NR continues to be the subject of considerable research efforts, particularly in the context of the widening gap between demand and supply of natural rubber. Over one million small farmers  in India owning less than 0.5 ha. of land depend on rubber cultivation for a livelihood.

A) Conventional breeding techniques
Conventional breeding techniques for spices involve various methods to improve traits such as yield, quality, disease resistance, and adaptability. Here’s an overview of conventional breeding techniques applied to specific spices:
1. Black pepper (Piper nigrum)
• Selection: Choose superior plants based on traits like yield, quality of peppercorns, and disease resistance.
• Hybridization: Cross-breed different varieties to combine desirable traits.
• Mutation breeding: Induce mutations to develop new traits or enhance existing ones.
2. Small cardamom (Elettaria cardamomum)
• Selection: Select plants with high yield, better quality, and disease resistance.
• Hybridization: Cross different varieties to improve traits such as pod size and essential oil content.
• Seed production: Improve seed production and quality through selection.
3. Large cardamom (Amomum subulatum)
• Selection: Identify plants with higher yield and better resistance to pests and diseases.
• Hybridization: Develop hybrids to enhance flavour and size of the cardamom pods.

ABSTRACT

Madhya Pradesh is declared as mega diversity state in India. It also harbours diversity in human population as 1/4^th of its population is tribal. These tribal people are practicing agroforestry since time immemorial. The state is divided into 11 agro climatic zones. The paper provides the agroforestry systems and species suitable for these zones. The traditional practices and the innovative agroforestry systems developed are also given. Agroforestry systems that are suitable for problematic soil have been briefly discussed. Efforts of different institutes like TFRI, JNKV and projects like TDET, ORP on Agroforestry, AICRP on AF in developing different system and their recommendations are also provided in this paper.

INTRODUCTION

Environment remained in its pristine purity and congeniality till man stayed in the hunting and food gathering stage. But, as he entered in the pastoral age and domesticated animals, he gradually passed from the nomadic stage to settled cultivation. When, he cleared the first patch of earth and upturned the first sod and lifted the first bucket of water, the long story of his interference with environment started. Clearing trees for farming, disturbing the moisture regimes and furrowing the land endangered the phenomenon of erosion leading on to the problem of reducing the soil fertility. At the same time, the art of Agroforestry emerged, though in the most rudimentary fashion, which in varying form and emphasis has continued till today. Coming to recent times, the increasing pressure on land as well as on forests, rising demand for fuel and fodder and finally the requirement of timber for multifarious purposes have strengthen the need of agroforestry as an alternate land use system especially at natural resource conservation front (Singh, 1999). Pathak (2000) opined that agroforestry is a land management system that optimizes the overall land productivity and reduces resources depletion through the utilization of positive interactions between crops-trees-animals in its temporal and spatial dimensions. In this way, agroforestry operates in a given socioeconomic frame work; it is not a static but a dynamic structure.

Introduction

Multiplication of plants is termed as propagation. Nowadays, propagation practice has been totally modernized. Propagation practices have advanced from field to in-vitro. Starting from scion stick of 15 to 20 cm length, the plants are multiplied even using cell, tissue and embryo. In modern horticulture trade, plant propagation is a soaring business. It is highly profitable, employment generative, recreative and creative business.

Several improvements have been noticed over the period of time in the basic techniques of plant propagation, using either conventional or tissue culture approaches. The propagation under protected environment by creating artificial conditions such as light, temperature and humidity under controlled irrigation through drip irrigation and fertigation has enhanced the potential of plant propagation and has made it possible to propagate the plants around the year.

In tropics, many crops are grown for their edible roots or tubers. Broad group of “tuber crops” encompasses a wide range of starchy food crops, some of which are true botanical roots and some others are stem tubers or corms. In global scenario, they are in a neglected state mainly due to their negative image as poor people’s food. They are highly perishable and are normally consumed locally in fresh or home processed state. It is time to bring out the positive attributes of these important foods and the increased contribution they can make to the nutritional welfare, food security and economic wellbeing of people, especially in developing countries.
