Introduction

Computerization in education is perpetual need of today. Computers store large quantum of data that can be retrieved and used wherever necessary. They can also be used as an interactive media in transfer of technology system, which aids farmers and extension workers to access in formation of their need and to communicate with each other. Positive advantages in web education over distance learning process are that farming community can access it from any part of the world. Web education has also the added advantage of updating its data base on weather conditions, market situation in hourly basis which is not possible distance education as the process need a long time with regard to the availability of human resource and static course material to be developed for a particular time frame. The distance learning process being conventional in nature and also in place for quite a long years has abundance of resources and infra structural facilities however in web education, the professional resources are less in number and still arm journalism is yet to gain popularity among them. So web based interactive knowledge network system in transfer of technology is a present need which has to be addressed with due attention to improve the quality of existing communication system.

Introduction
Agriculture is an age-old income generation activity in India. It plays a vital role in India’s economy. One in every two Indians relies on agriculture for livelihood. Over 58% of the rural households depend on agriculture as their principal means of livelihood. Over the period of time, the contribution of agriculture and allied sector in Gross Domestic Products (GDP) in India has declined to 14.4% in 2018- 19 from 51.8% in 1950-51. At current prices, the contributions of industry and services sector are 31.5%, and 54.1%, respectively as against the contributions of industry and services sector were 15.1% and 33.1%, respectively in 1950-51. This decline in share of agriculture and allied sector is result of the shift from traditional agricultural economy to industry and service sectors, this performance are very meagre if we consider the size of the employment in this sector. Presently, more than 50% of the total workforce of the country is employed in agricultural sector contributing to only 14.4% of GDP. With production of agriculture activity 26of $375.61 billion, India is 2nd larger producer of agriculture product in the world after China which has contribution of $991 billion in agriculture sector. GDP of industry sector is $560.97 billion and world rank is 6th. In services sector, India’s world rank is 8th and GDP is $1500 billion (FAENI, 2018- 19). Interestingly, contribution of agriculture sector in Indian economy is much higher (7.4%) than world’s average (6.4%), while contribution of industry and services sector is lower than world’s average (30% for industry sector and 63% for services sector).

Agricultural extension services play a pivotal role in facilitating better management of produce by providing farmers with knowledge, resources, and support to improve their agricultural practices. These services act as a bridge between agricultural research and farmers, disseminating information on innovative techniques, technologies, and best practices tailored to local conditions. Through workshops, training sessions, field demonstrations, and one-on-one consultations, extension agents empower farmers to adopt sustainable production methods, optimize inputs, and enhance crop yields while minimizing environmental impact. By promoting efficient post-harvest handling, storage, and marketing strategies, extension services help farmers reduce post-harvest losses, improve product quality, and access lucrative markets. Additionally, extension programs often incorporate valuable information on crop rotation, integrated pest management, soil conservation, and water management practices, enabling farmers to make informed decisions for long-term agricultural sustainability. Ultimately, agricultural extension services serve as catalysts for innovation, productivity, and resilience in the agricultural sector, contributing to food security, economic development, and rural livelihoods.

ABSTRACT

The conventional agricultural extension service in India is mainly provided by extension workers visiting farmers to provide agricultural advisory services. This system of extension service provision faces a number of challenges including the few number of extension workers and limited resources. The effectiveness of an impact-driven, radio-based extension service delivery system that has been introduced in some rural areas of India. The system aims to enable extension workers to reach many farmers with minimum efforts. However little is known about the effectiveness of this new extension service delivery system. In rural areas, farmers have started sharing agricultural related information and best practices. Some farmers have also started to change their farming practices. This brings a new finding that farmers can adopt and practice easily what is aired by their fellow farmers in the community radio stations.

Introduction 
Agricultural extension systems are vital in bridging the gap between research and practical application by farming communities. By providing farmers with access to the latest technologies, practices, and knowledge, these services help improve crop yields, optimize resource use, and promote sustainability. Beyond just technical advice, agricultural extension often involves helping farmers adapt to new market trends, climate changes, and government policies. Extension agents typically work directly with farmers through meetings, oneon- one consultations, and community-based demonstrations. Dr. Rajendra Prasad Central Agricultural University, originally known as Rajendra Agricultural University, was established as India’s first Imperial Agriculture Research Institute. The foundation stone was laid by Lord Curzon on April 1, 1905, with financial support from American philanthropist Henry Phipps, Jr. Located in Pusa, Bihar. It is an Institute of National Importance. The University focuses on teaching, research, and extension, with the Directorate of Extension Education founded in 1977. This Directorate bridges the gap between technology generation and dissemination by coordinating with the State Department of Agriculture, ICAR, and other research and training institutes. It aims to deliver the latest agricultural information to farmers through its colleges and Krishi Vigyan Kendras (KVKs), as well as plan and monitor extension activities based on research results. Public spending on Agricultural extension is one of the key policy instruments of the government to provide growth and alleviate property in rural areas. A comprehensive analysis of farming systems is essential to identify areas that need training, highlight technology gaps, address the adoption gap, and recognize production constraints. The goal is to develop and showcase alternative sustainable farming practices that enhance farmers’ productivity and profitability while conserving biodiversity and improving environmental health. Additionally, farmers should be connected to the rapidly evolving global market by providing them with relevant information and guidance to help them adapt to new opportunities and challenges.

Meaning, Concept & Definition of Education

1. “Education is the process of developing capabilities of the individuals so that they can adequately respond to their situations”.

2. The modern definition of Education- “It is the production of desirable changes in human behavior- in knowledge (things known), attitudes (things felt) and skills (things done), in all of them or in one or more of them”.

3. Education is the process of giving training and instruction to people to develop their knowledge, abilities, skills, character and mental powers.

Knowledge: It includes-facts, concepts, principles and relationship.

For example: Extension worker educates a farmer on cultivation practices in sweet corn. (Things known)

Attitude: An attitude can be loosely defined as a feeling towards some object, person, and situation or idea. For Example

Introduction

Agriculture is an important sector of Indian economy and it contributes about 17.4% to the country’s Gross Value Added (GVA) for the year 2016-17 provides employment to over 54.6 % of the population. There has been a continuous decline in the share of agriculture and allied sector in GVA from 18.6% in 2013 14 to 17.4% in 2016-17. Falling share of agriculture and allied sector in GVA is an expected outcome in a fast growing and structurally changing economy. However since 54.6% of the population is still dependent on agriculture and engaged in improving the agricultural production and overall income. The agricultural production system required timely and adequate agriculture credit to fulfill farmers need. Agricultural Finance ensures provision of multiple types of services dedicated to support both on- and off-farm agricultural activities and businesses including input provision, production, and distribution, wholesale, processing and marketing.

Introduction

Poverty has been described as a situation of “pronounced deprivation in well being” and being poor as “to be hungry, to lack shelter and clothing, to be sick and not cared for, to be illiterate and not schooled. Poor people are particularly vulnerable to adverse events outside their control. They are often treated badly by institutions of the state and society and excluded from voice and power in those institutions.” Lack of access to resources is a unifying characteristic of poverty in all its manifestations. The poor lack ownership of or access to assets such as land, water, forest, dwelling units, credit, literacy, longevity, voice and capital-both physical and social. Those who are severely below the poverty line are largely involved in subsistence type activities for which they get exploitatively poor returns despite suffering extreme physical hardship and undertaking grave risks so as to earn a meager income. Since earnings are below even the margins of existence, expenditure and survival needs exceed income. This often results in the need to borrow small amounts of money at usurious interest rates of as much as 120 per cent per annum (Mehta, 1996) when borrowing is not possible, hunger is suffered. Their inability to change the power relationships results in scarcely available common resources (such as even drinking water) or public funds meant for poverty alleviation being misappropriated and diverted through manipulation by the locally powerful or corrupt. Since there are no mechanisms for grievance redressal this could result in social tension, despair or a combination thereof.

History is the continuous record of past events

Heritage is the inherited values carried from one generation to other generation

Agricultural heritage refers to the values and traditional practices adopted in ancient India which are more relevant for present day system.

Agricultural Heritage in India

Agriculture in India is not of recent origin, but has a long history dating back to Neolithic age of 7500-6500 B.C. It changed the life style of early man from ‘nomadic hunter of wild berries and roots’ to ‘cultivator of land’. Agriculture is benefited from the wisdom and teachings of great saints. The wisdom gained and practices adopted have been passed down through generations. The traditional farmers have developed the nature friendly farming systems and practices such as mixed farming, mixed cropping, crop rotation etc. The great epics of ancient India convey the depth of knowledge possessed by the older generations of the farmers of India. The modern society has lost sight of the importance of the traditional knowledge which had been subjected to a process of refinement through generations of experience. The ecological considerations shown by the traditional farmers in their farming activities are now-a-days is reflected in the resurgence of organic agriculture.

Introduction

Agriculture denotes as the key development in the rise of sedentary human civilization, where by farming of domesticated species creates food surpluses that enables people to survive and showing them the way of earning. Thus our country is enhancing agro-based industries. Industrial agriculture based on large scale monoculture, which is dominated by agricultural output. Hence it is the dynamically economic improvement of our country with the help of agriculture basing on modern information technology. Information technology means the latest version of information facilities like computer, mass media and Internet. Information technology (IT) or Information communication technology (ICT) is a broad subject concerned with technology and other aspects of managing and processing information.

Information technology contributes much to agriculture and rural development. It facilitates rural activities and provides more comfortable and also saves the rural life with equivalent services to those in urban areas such as provision of distance education, tele-medicine, remote public services, remote entertainment etc. IT initiates new agricultural and rural business such as e-commerce, real estate business for satellite offices, rural tourism, and virtual corporation of small-scale farms. It also supports policy-making and evaluation on optimal farm production, disaster management, agro-environmental resource management etc using tools such as geographic information systems (GIS). It also helps in improving farm management and farming technologies by efficient farm management, risk effective information or knowledge transfer etc realizing competitive and sustainable farming with safe products.

Introduction Market-led extension is a strategic approach aimed at providing farmers with valuable and high-quality information to enhance their decision-making processes in both production and marketing. This approach acknowledges the global nature of modern markets and encourages farmers to transition from being mere producers in local markets to becoming sellers in broader, potentially international markets. To make this shift successful, it is essential to equip extension workers, those who offer agricultural guidance, with the necessary skills and knowledge about market dynamics (Ahmad and Slathia, 2011). This involves a shift in their approach, moving from solely focusing on increasing productivity to emphasizing profitability. It also involves transitioning from subsistence farming to a more commercial orientation, from single-commodity farming to diversified crop production, and from local markets to global export markets.

Agricultural innovations are crucial for addressing the pressing challenges of food security, environmental sustainability, and economic development. Around the world, innovative practices and technologies are transforming agriculture by increasing productivity, enhancing resilience to climate change, and improving livelihoods. This article provides an in-depth exploration of notable agricultural innovations, spanning traditional practices, cutting-edge technologies, and holistic approaches. By examining these innovations and their impacts, we can gain valuable insights into how agriculture is evolving to meet global needs.

Introduction

Agriculture is undergoing a profound transformation driven by technological advancements, sustainable practices, and innovative approaches. Innovations in farming have the potential to enhance productivity, resilience, and sustainability, thereby addressing global challenges such as population growth, climate change, and food insecurity. This article examines pioneering agricultural innovations from different continents, highlighting their applications, benefits, and implications for the future.

Agro-inputs are either biological or chemical or inorganic compounds used in the production of agricultural and allied products. Some of the agro-inputs used in India are :

• In-organic fertilizers
• Pesticides which include insecticide, fungicide, nematicide and herbicide
• Seeds which include varieties, hybrids and genetically modified plant materials
• Vegetatively propagated planting materials
• Bio-fertilizers
• Organic inputs which include compost, vermicompost, enriched farm yard manure, oil meals and farm yard manure
• Bio-pesticides
• Bio-control agents
• Plant Growth regulators
• Micro-nutrients
• Farm machinery and agricultural tools and implements
• Animal feed
• Poultry feed.

The production and distribution of above mentioned agricultural inputs create agri-business opportunities. The agricultural input production inputs and distribution firms may be big companies like Madras Fertilizers, SPIC, FACT, EID Parry, Monsanto, Syngenta or MAHYCO and the like. They may also be small business firms like vermicomposting, coir pith decomposing.

Formed 1 April 2003 took over implementation of National Agricultural Insurance Scheme (NAIS) from General Insurance Corporation of India.

Also transacts other insurance businesses directly or indirectly concerning agriculture and its allied activities.

Abstract

Entrepreneurship essentially involves economic and dynamic activities, risk- assuming and idea generation that help in developing, organising and managing a business opportunity for profits. Entrepreneurship in agriculture is not merely confined to farm activities but also involves activities interlinked and interdependent with core and peripheral agricultural activities. Impediments in the pathway of agricultural entrepreneurship in West Bengal are characterised by fragmented landholding, low financial resources and thereby debt stickiness & dependence on short-term agricultural loan. Though disbursements of short-term credit have increased substantially, the rate of increase is low. For most farmers, insurance for financial or crop crisis is unheard or have hardly any implication. The paper tries to explain the performance of various agricultural insurance schemes in terms of coverage and the benefits being delivered in India and in West Bengal. The paper analyses whether the recipients consider the schemes as an effective risk mitigation tool or merely a habit of credit-dependence in West Bengal through a diffusion model. The paper concludes with the focus on possible entrepreneurial opportunities that may offer more customised agri-insurance policies, where regional disparities could be considered and individual interests be given little more importance.

Agricultural Journalism

Journalism refers to the production and distribution of reports on recent events. The word journalism applies to the occupation, using methods of gathering information andutilizing literary techniques. Various forms ofjournalistic mediums include: print, television, radio, Internet and in the past: newsreels. The activity or profession of writing for newspapers, magazines, ornews websites or preparing news to be broadcast. The difference between Farm journalism and general journalism.

Definition

Agricultural journalism is a specialized branch of journalism that deals with the techniques of receiving, writing, editing and reporting from information through the media like newspapers, periodicals, radio, TV, advertising etc. and the management processes connected with such production. It is the timely reporting and editing with words and photography of agricultural news and information for newspaper, magazine, radio and television.

It is otherwise known as Farm journalism

Farm journalism is very important for communicating with farm people. More and more of the extension staff’s writing is being read or listened to in newspapers, magazines, brochures, pamphlets, bulletins, circular letters, wall newspapers, and radio scripts. The written work makes working as a consultant with farmers more fascinating.

Principles of Farm/Agricultural journalism

Meaning and Definitions

Agricultural journalism refers to the specialized field of journalism focused on reporting, analyzing, and disseminating information related to agriculture, farming, rural development, and related topics. It plays a crucial role in educating and informing the public, policymakers, and stakeholders about the agricultural sector, its challenges, innovations, and contributions to society.

Here are a few definitions of agricultural journalism.

Agricultural Livelihood Systems (ALS) refer to the complex set of interactions between farming practices, economic activities, social structures, and environmental factors that influence the livelihoods of communities,
particularly in rural areas. In regions like India, where a significant portion of the population depends on farming for sustenance and income, understanding ALS is crucial for planning sustainable rural development and poverty alleviation. The meaning of Agricultural Livelihood Systems extends beyond just crop cultivation. It includes a variety of interlinked activities such as livestock rearing, agroforestry, fisheries, horticulture, and non-farm support services like input supply, processing, and marketing. These systems are influenced by agro-ecological conditions, landholding patterns, socio-economic status, access to infrastructure, and institutional support. A household’s livelihood strategy may be entirely agriculture-based or may combine farming with offfarm and non-farm income-generating activities. The approach to Agricultural Livelihood Systems is holistic and peoplecentered. It emphasizes understanding the livelihood strategies of farming households in the context of the resources they possess, the constraints they face, and the opportunities available to them. Rather than focusing solely on increasing agricultural productivity, the ALS approach takes into account sustainability, equity, resilience, and diversification. These systems encompass a mix of agricultural and non-agricultural activities that contribute to the
overall wellbeing of individuals and households.

Introduction

Agriculture, in most developing countries is the major industry. More than 50 percent of the labour is working in this sector and its industrial and commercial branches. In these countries, also more than 50 percent of the households‘ incomes are spent for low quality and value foods. Inefficiency of the agricultural products marketing system is the starting place of these problems.

1.    A series of activities involved in moving the agricultural goods and services from production point to ultimate consumers is known as–

(a) Agricultural marketing

(b) Agricultural selling

(c) Marketing

(d) Agricultural finance

2.    The study of all the activities, agencies and policies involved in the procurement of farm inputs by the farmers and the movement of agricultural products from the farm to consumers is known as :–

(a) Personal selling

(b) Agricultural marketing

(d) None of these

Traditionally, agriculture in India was practiced on a subsistence basis; the villages were self sufficient, people exchanged their goods, and services within the village on a barter basis. But, with the development of means of transport, storage facilities and other infrastructure, agriculture has become commercial in character. The hills of India produces a wide range of goods starting from temperate fruits like apple to subtropical fruits like guava and cash crops like saffron, kala zeera, buckwheat etc. that are demanded at every corner of the country and even the world. The hills in India lacks infrastructure because of which farmers are not able to fetch a better price for their produce.

Agriculture is the dominant activity in the hill economy, which confronts multiple risks and uncertainty. The low yield of food and cash crops, fodder, fuel and other minor forest produce and their stagnant growth affected the agrarian economy and in particular the household food security. The scattered land holdings, traditional mode of production, low use of modern inputs and lack of market incentives are the primary causes of the poor performance of agriculture in J&K. Increase in Seed Replacement Rate (SRR) of major crops, Popularization of hybrids, Soil and Water conservation measures, and Public-private partnership are important aspects need to be considered for agriculture development in hilly areas of J&K. Strengthening of markets, Innovative marketing techniques and On-line trading can help in a big way for solving the problems of marketing in such areas.

Agricultural sector need efficient functioning of its markets to stimulate economic growth and incomes of the large rural population dependent on agriculture. More than three-fifths of India’s population draws their livelihood from agriculture that adds just one-fifth to its GDP. There should be obvious serious concerns about efficient functioning of this sector both in terms of its output / productivity and its marketing. While output and productivity are supply side factors, markets provide an intermediate link between producers and final demand by consumers. An efficient marketing system is pertinent for optimization of the resource use, output management, improving farm incomes, growth of agro -based industry and enhancing value addition. The efficient markets are also important for the stable consumer prices, higher returns to the farmers and reducing post harvest losses. Efficiently functioning markets add to welfare of producers as well as consumers. For markets to work efficiently it is pertinent to link the farm gate with retail outlets so as to reduce losses and marketing costs. However, it requires an institutional framework and infrastructure to prepare the produce in the form demanded by the consumers.

Mechanization should not be an end in itself and therefore, in a free choice situation, Governments should refrain from making policies which will stipulate by which means or by how much, agriculture will be mechanized. The type and degree of mechanization should be decided by the producer to best suit his business and his own particular circumstances, and the choice of suitable methods will therefore be just one of a number of choices that the farmer has to make. The decision on if and how to mechanize is often a complicated mix of reasons with economic reasons paramount. The introduction of machines will not only make agriculture more acceptable but will also provide opportunities for the use of higher intelligence, skill and initiative. This chapter attempts to work out the comparative economics of some of the machinery that are useful for hill regions.

For the sustainable development of agricultural mechanization, it is needed to locally fabricate widely used agricultural tools, implements and machinery. However, the prevailing policy does not favour production of agricultural machinery locally (high custom duty of raw materials, no support in promotion, irregular power supply, high electricity cost, poor research & testing support etc.). Hence there is need of reform in policy and program to encourage and support local fabricators to fabricate/manufacture agricultural machinery locally. There is need of testing and standardization of agricultural machinery to reduce the accidents related to agricultural machinery and to provide quality standard agricultural machinery to the farmers.

Mechanization is viewed as package of technology to increase land productivity by improved timeliness of operations, reduced crop losses and improved quality of agro-produce to increase efficiency of inputs used through their efficient measurement and placement, to increase labour productivity by using labour saving and drudgery reducing devices and reduce cost of cultivation. echnology and machinery enhanced the ability, quality, accuracy and efficiency of the human being. By using technology in any field the rate production and quality automatically increases. The country witnessed unprecedented growth in agriculture which has helped India to graduate from hunger to self sufficiency in food grains by increasing the food grain production from 51 million tonnes to 208 million tones. The estimated contributions of improved agricultural tools and equipment in augmenting total food production of India is encouraging; savings in seeds: 15-20%; savings in fertilizers: 15-20%; savings in time: 20-30%; reduction in labour: 20-30%; increase in cropping intensity: 5-20%, and increase in productivity 10-15 per cent. The major issues before Indian agriculture with respect to mechanization are; tractorization vs mechanization, custom hiring and contract farming, horticultural mechanization, effective extension activity, sugarcane mechanization, hill agriculture and industry institution interaction. The main technologies which can be taken to farmers’ field for enhancing productivity and production Aqua-ferti seed drill, two row powered seeder, okra planter, tractor mounted inclined plate planter, tractor mounted rotary tiller (Rotavator), tractor mounted zero-till drill, tractor mounted raised bed planter, tractor mounted sett cutter planter for sugarcane, pneumatic planter, vegetable transplanter, low land manual rice seeder, self-propelled rice transplanted, self-propelled power weeder, tractor operated aero blast sprayer, tractor mounted vertical conveyor reaper, maize dehusker-cum-sheller, tractor operated straw reaper (combine) and tractor operated fodder harvester. These technologies need to be introduced after necessary modifications and adjustments, depending upon the agroclimatic and terrain and soil conditions, through proper mode e.g. as individual /group ownership, on custom hiring basis or mechanization package for contract farming.

Agricultural Meteorology, also known as Agrometeorology, is a fascinating scientific field that explores the intricate relationship between weather, climate, and farming. It essentially bridges the gap between understanding the atmosphere and the practicalities of growing crops, raising livestock, managing forests, and even fisheries. The core idea is to figure out how environmental factors like light, temperature, water, and wind impact every stage of agricultural production, from initial planning to harvest and marketing. 1.2 Scope of Agricultural Meteorology At its heart, agrometeorology investigates how various weather elements— temperature, rainfall, humidity, sunlight, wind, and even atmospheric pressure and CO2 levels—directly and indirectly affect agricultural systems. This includes how weather influences crop growth and development, impacting crucial processes like photosynthesis, respiration, and

In an era defined by increasing climate variability and the urgent need for sustainable food production, the science of Agricultural Meteorology has risen to unprecedented importance. This final chapter, “Agricultural Meteorology: A Science for Global and National Food Security (in the context of climate change),” synthesizes the principles and applications we have explored, highlighting their critical role in ensuring food security at both global and national levels, particularly within the challenging framework of a changing climate.
We have seen how weather and climate intricately influence every aspect of agriculture, from planting to harvest, and how extreme events can decimate livelihoods and threaten food supplies.1 Now, we will focus on how the interdisciplinary field of agricultural meteorology – the study of the interactions between meteorological and hydrological factors and agriculture in the widest sense – provides the knowledge and tools necessary to navigate these challenges.
This chapter will underscore how understanding and applying agrometeorological principles, including crop-weather relationships, climate risk assessment, and the use of decision support systems, are essential for developing climate-resilient agricultural practices. We will explore how this science aids in optimizing resource management, predicting and mitigating the impacts of weather-related hazards, and ultimately, in building sustainable and secure food systems for the future, both globally and specifically within the Indian context.

In an era defined by increasing climate variability and the urgent need for sustainable food production, the science of Agricultural Meteorology has risen to unprecedented importance. This chapter, “Agricultural Meteorology: An Essential Associate for Natural Farming,” synthesizes the principles and applications we have explored, highlighting their critical role by providing timely, location-specific insights into weather and climate - factors that directly influence crop growth, soil health, and ecological balance. Unlike conventional farming, which often relies on synthetic inputs to manage uncertainty, natural farming depends heavily on understanding and adapting to natural rhythms. Here, agrometeorology becomes an indispensable ally.
Natural farming systems are sensitive to changes in temperature, rainfall, humidity, wind, and solar radiation. Agrometeorology helps farmers monitor and interpret these parameters, enabling them to make informed decisions such as when to sow, irrigate, mulch, or harvest — all without chemical interventions. For instance, knowing the onset of monsoon or forecasted dry spells helps in planning sowing operations or preparing natural plant protection measures like cow dung-based formulations.

Meteorology is a branch of physical sciences, which studies the physical properties of earth's atmosphere, and it is a combination of physical and geographical sciences. It is an applied science using the principles of physics to understand the physical state and behaviour of atmosphere.

In meteorology, weather describes the physical state of atmosphere of a particular place in a given point of time, usually for a shorter duration. On the other hand, climate describes the state and dynamics of the same set of weather variables of a particular place for a longer period.

Important Points to Remember

• Microbiology is the study of living organisms of microscopic size majority of which are too small to be observed with naked eye, include bacteria, fungi, algae and protozoa and the infectious agents at the borderline of life that are called viruses.
• However, a few members of some microbial groups like algae and fungi are clearly visible without the aid of microscope.
• It is concerned with their form, structure, reproduction, physiology, metabolism and classification. It includes the study of their distribution in nature, their relationship to each other and other living organisms, their effects on human beings and on other animals and plants, their abilities to make physical and chemical changes in our environment and their reactions to physical and chemical agents.
• Most microorganisms are unicellular in which all the life processes are performed by a single cell. All living cells contain protoplasm which is a colloidal organic complex consisting of largely proteins, lipids and nucleic acids.
• The major groups of microorganisms include Prokaryotic and Eukaryotic microorganisms.

4.1. Introduction
The agricultural sector plays a vital role in a nation’s economic development. It has been a key driver of prosperity in advanced economies and remains essential for the progress of developing nations. In regions with low per capita real income, agriculture and other primary industries are given high priority. As Dr. Bright Singh emphasizes, “An increase in agricultural production, along with a rise in the per capita income of the rural population, fosters industrialization and urbanization, thereby boosting demand for industrial goods.”
The historical trajectory of England provides clear evidence that the Agricultural Revolution preceded and laid the foundation for the Industrial Revolution. Similarly, in the United States and Japan, agricultural advancement has played a pivotal role in fostering industrialization. Many developing nations, in their pursuit of economic growth, have recognized the limitations of an excessive focus on industrialization as a sole strategy for achieving higher per capita real income.
Industrial and agricultural development are not substitutes but rather complementary forces that mutually reinforce each other in terms of both inputs and outputs. Empirical observations indicate that enhanced agricultural productivity and output significantly contribute to a nation’s overall economic progress. Therefore, prioritizing the further development of the agricultural sector is both rational and essential.

Agricultural policies shape the landscape of farming and food production globally. They encompass a range of interventions by governments to influence agricultural practices, food security, trade, and rural development. This article delves into the various types of agricultural policies, their historical context, and their socio-economic and environmental implications. It examines case studies from different regions to highlight the diverse approaches and outcomes of these policies. Additionally, the article discusses the challenges and opportunities in formulating and implementing effective agricultural policies, particularly in the face of global issues such as climate change, food insecurity, and market volatility. By understanding the impact of agricultural policies, stakeholders can better navigate the complexities of the agricultural sector and promote sustainable development.

14.1. Commission for Agricultural Costs and Prices (CACP)

Set up in January, 1965 in name of Agricultural Prices Commission (APC) on recommendations of Food grains Prices Committee headed by Shri L.K.Jha.

Prices for different agricultural crops by GOI on the recommendations of CACP are announced as minimum support prices, statutory minimum prices, procurement prices and issue prices.

Introduction

India has made impressive strides on the agricultural front during the past three decades. Much of the credit for this success should go to the several million small farming families that form the backbone of Indian agriculture and Indian economy. Policy support, production strategies, public investment in infrastructure, research and extension for crop, livestock and fisheries have significantly helped in increasing the agricultural productivity, food production and its availability. Notwithstanding these achievements, producing additional food with limited land, and providing economic access to food at the household level for ensuring food security would continue to be a major challenge for the nation. India has experienced considerable changes in the crop mix, yield and production since the inception of the Green Revolution. The Green Revolution phase displayed a high yield growth per unit of input. The first post-Green Revolution phase (from late-1960s to mid-1980s) was marked by the continued growth in returns from land through the intensification in use of chemical inputs and machine labour. The second post-Green Revolution phase (beginning the mid-1980s) was characterized by high input-use and decelerating productivity growth. It calls for an examination of the issues related to the trends in agricultural productivity, particularly with reference to individual crops in recent years. In the present paper, the temporal and spatial variations in the productivity status of major crops in India have been analyzed using the TFPG estimates. Some policy measures have also been suggested for sustaining TFP of the crops.

The recent earthquake in Nepal brings back memories of 26th January 2001. While the nation was busy in celebrating Republic Day, an earthquake shattered Gujarat especially Kutch and Saurashtra regions. A large number of buildings and houses collapsed within moments. Thousands were injured and many lost their lives and many more became homeless.

Kutch received quick responses from all over the world and a large number of individuals, institutions, government and semi-government bodies, professional experts, religious and social organizations etc. sprang into action to bring back some normalcy in the lives. However, long-term rehabilitation program based on scientific planning is most vital after such disasters.

I. Crop Wastes

Crop residues are the main sources for recycling of the organic and plant nutrients removed from the soil during the growth of crops. These residues have competitive uses such as fuel and cattle feed. There was an estimated demand of 583.6 million tonnes of dry fodder against the supply of aljout 398.8 million tonnes (Singh, 1997). Besides the use of crop residues as animal feed, industrial uses of crop residues also pose competitive demands. The potential of crop residues of some principal crops was worked out by Bhardwaj (1995). It was assumed that not more than one third of the total crop residues (273.63 million tonnes) was available for recycling as plant nutrients (Table 21). Out of a total 5.61 million tonnes (N+P2 O5 +K2 O) available in the form crop residues, only 2.47 million tonnes can be mobilized either through composting or in situ incorporation or mulching. Based on these estimations, Sekhon (1997) projected that approximately 4.82 and 5.79 million tonnes of N+P2 O5 +K2 O will be available from recycling of crop residues by the year 2011 and 2025 with utilizable value of 2.21 and 2.26 million tonnes respectively (Table 22).
