1.1 Some Useful Formulas Related to Farm Machinery

Farm machinery is a range of mechanical implements used in agriculture production from land preparation to harvesting and processing the produce. It includes various ploughs, tractors, broadcaster, harvester and post harvest processing machineries. The purpose of using machines in agriculture production is to handle the mass production, improve the efficiency and to save the labour costs. The types of implements used in fodder production are tillage, sowing, intercultural, plant protection and harvesting equipments.

25.1 Introduction

Farmers must be able to take appropriate decisions at appropriate time. Incorrect judgement and decisions will return in failure of execution of farm plan and in turn economic loss. The farm management decisions can be broadly categorised into two ways.

19.1 Introduction

The farm management comprises of two words: ‘farm’ and ‘management’. Literally ‘farm’ means a piece of land where crops and livestock enterprises are taken up under a common management and has a specific boundaries. ‘Management’ means the act or art of managing, the agricultural production or enterprises etc.

1. Introduction

The status of mechanization in India is at a very low level for horticultural crops. The farmers usually go behind the use of traditional methods for different farm operations (Fig 1) and practices for cultivation of horticultural crops, their handling, storage, and processing. This results in less yields, high cost of cultivation and high crop losses from harvesting till processing. The use of different available hand tools, machinery and hi-tech technologies in the production and processing of the crops will lead to increased yields and decrease in losses to a great extent (Mandhar, 1999).

Farm mechanization plays a crucial role in the evolution and efficiency of f loriculture, the cultivation of flowers and ornamental plants for gardens and f loristry. The introduction of advanced machinery in floriculture enhances productivity, reduces labor costs and ensures the consistency and quality of f loral products. Mechanization encompasses various stages of the floriculture process, including soil preparation, planting, irrigation, pest control, harvesting and post-harvest handling. Equipment such as automated seeders, transplanters greenhouse climate control systems, drip irrigation setups and harvesting machines streamline operations, leading to higher yields and reduced manual labor. Moreover, mechanized techniques facilitate precision farming, enabling growers to optimize resource use and minimize environmental impact. The use of drones and sensor technologies allows for meticulous monitoring of crop health, ensuring timely intervention and reducing losses due to pests and diseases. By incorporating mechanization, floriculture can meet the increasing global demand for flowers and ornamental plants while adhering to sustainable agricultural practices. Additionally, the adoption of mechanized processes supports the scalability of floriculture businesses, making them more competitive in the market. Thus, farm mechanization is instrumental in transforming floriculture into a more efficient, sustainable and profitable sector, aligning with modern agricultural trends and consumer expectations.

Farm Mechanization refers to the use of various mechanical, electrical, and hydraulic equipment and technologies in agriculture to perform tasks that were traditionally done by hand or with animal power. These machines and tools are designed to make farming operations more efficient, productive, and cost effective. Farm mechanization encompasses a wide range of equipment, from tractors and plows to harvesters and irrigation systems.

It’s important to note that while farm mechanization offers numerous benefits, it also presents challenges, such as the initial cost of machinery, the need for maintenance and technical knowledge, and concerns about the displacement of rural labor. As a result, the adoption of mechanization in agriculture varies widely by region and type of farming operation

Present Status of farm Mechanization in India

In India, farm mechanization has been a key focus for increasing agricultural productivity and reducing labor-intensive farming practices. Here are some key points on the status of farm mechanization in India:

1. Government Initiatives: The Indian government, through various agencies, has been promoting and supporting the adoption of farm mechanization. Schemes such as the “Sub-Mission on Agricultural Mechanization” (SMAM) have been launched to provide subsidies and f inancial incentives to farmers for purchasing agricultural machinery and equipment.

7.1. Farm planning

Decision making process in farm business

Involves organization and management of limited resources to realize specified goals continuously.

Selecting most profitable course of action from among all possible alternatives.

22.1 Farm Planning

It refers to setting the objectives and actions to be taken in directing or controlling the organisation of farm business and it precedes all other managerial functions on the farm to achive the desired results. It is deciding in advance to the production management problems viz. what to produce, how to produce, when to produce, financial management problems viz how to borrow, how much to borrow, when to borrow, from where to borrow and marketing management problems viz, where to buy, and sell, when to buy and sell, how to buy and sell ete. Farm planning governs the survival progress and prosperity of farm organisation in a competitive and dynamic environment. It is a continuous and unending process. Farm planning is as old as farming itself but mainly it uses the farmal planning.

1.1 Introduction

Water is the basis of all forms of life. It supports life system not only to the plants but also to all other animals. The embryo from the conception till birth floats in the liquid medium. Cell, the basic unit of life, contains as high as 95- 98% water. Cellular metabolism is controlled by content of water. Majority of this water requirement of the crops is met from different forms of precipitation. However, when the water requirement is not fully met from precipitation, then growth of the crops is affected. This results in reduction of yield of the crops. The reduction in yield depends on the amount of scarcity of water requirement of the crops. Water requirement of crops depend on many factors. It depends on the type of crops, irrigation schedules practiced, soil texture, position of groundwater table below the effective root zone of the crop and management practice followed in crop cultivation. The pulses, oilseeds, vegetables which are also otherwise termed as dry land crops need less water compared to rice which is a water loving crops and perennial crops like sugarcane and banana.

Water requirement of crops is partly met by the upward flux of groundwater. The capillary rise of shallow water table in the form of upward flux helps in meeting the water requirement of crops to some extent. The upward flux depends on the type of the soil, effective root zone depth of the crop, depth of water table below effective root zone depth of the crop and potential gradient of soil moisture suction. The residual soil moisture helps in supporting water requirement of crops also. The heavy soil like clay has more moisture retention capacity than the light soils like sandy soil. The residual soil moisture held in clay soil is released slowly and supports soil moisture to the crops for a longer period than the sandy soil which has less soil moisture retention capacity. After meeting the water requirement of crops from all sources including different forms of precipitation, ground water contribution by capillary rise and residual soil moisture, if there is any shortage of water, then this shortage should be met from other sources which is called as irrigation.

12.1 Introduction

Farm ponds are used for multipurpose including as a viable source for supplemental irrigation to rainfed crops, a good place of entertainment, a vital place for wild life habitats, livestock and fish and aquatic plants. Like any other structure, the farm pond needs regular repair and maintenance for effective operation. The purpose of construction of the pond will be fruitful and the life span of the pond will be enhanced if proper care and maintenance are taken. In this chapter some salient discussions on care and maintenance of the pond are mentioned.

12.2 Maintenance Against Silting

The farm ponds constructed in medium to deep black soils are subjected to getting silted up. Hence, periodic desilting to restore the original storage capacity is required. If the pond is used for supplemental irrigation to crops, then desilting may be done once in every 5 to 10 years depending on the amount of silt getting deposited in the pond.

The breaches and rill formed in the spoil bank and shoulder bunds should be immediately repaired. The inlet and outlet structures should be maintained periodically. The silt deposited in the silt trap should be removed periodically. In areas where silt carried by the runoff is more, a vegetative filter near the inlet structure may be used. The pond may be desilted manually if it is small in size otherwise mechanical measures may be used to desilt. It is easy to desilt the pond when it is dry. A Simple and inexpensive method to desilt the pond is to stir the water of the pond and then allow the desilted water move away from the pond through the outlet (Belgaumi, et. al., 1997). Fig. 12.1shows a badly maintained pond with excess silting and weed infestation causing severe reduction of its storage capacity.

Agricultural processing, often referred to as agro-processing, is the transformation of raw agricultural materials into products that are suitable for consumption or further manufacturing. This process adds value to agricultural products, enabling them to be stored, distributed, and marketed more effectively.

Agricultural Processing can Involve a Range of Activities, Including

Cleaning and sorting: Removing impurities, dirt, and unwanted materials from the raw agricultural produce.

Grading and quality control: Sorting products based on size, shape, and quality to ensure consistency and meet market standards.

Preservation and storage: Using various methods such as drying, freezing, canning, and refrigeration to extend the shelf life of perishable agricultural products.

ABSTRACT

Communication is now one of the central issues in developing societies. Knowledge expansion, information technology and technology dissemination are the three very important dimensions of any development system be it agriculture, industry and whatever. Revolutionary changes in communication policies, techniques and strategies are needed in order to make information is a fundamental right to the poor rather than making communication a privilege enjoyed by the rich and powerful. Transfer of agricultural technology generally aims at speedy diffusion of novel agricultural information from the place of invention to the place of adoption. In the current Information and Communication Technology (ICT) era, human dependency on computer and allied modern electronic gadgets for executing day to day activities is inevitable. All fields are being influenced by the interventions of ICT and agriculture is in no way an exception to it.

Indian agriculture is predominantly a rainfed agriculture under which both dry farming and dry land agriculture is included. Dry farming was the earlier concept for which amount of rainfall (less than 500 mm annually) remained the deciding factor for more than 50 years. In modern concept, dry land areas are those where the balance of moisture is always on the deficit side. In other words, annual evapo-transpiration exceeds precipitation. In dry land agriculture, there is no consideration of amount of rainfall. It may appear quiet strange to a layman that even those areas which receive 1100 mm or more rainfall annually fall in the category of dry land agriculture under this concept. The success of crop production in these areas depends on the amount and distribution of rainfall, as these influences the stored soil moisture and moisture used by crops. The amount of water used by the crop and stored in the soil is governed by the water balance equation: ET = P-(R+S). When the balance of the equation shifts towards right, precipitation (P) is higher than ET, so that there may be water logging or it may even lead to run off (R) and flooding (S). On the other hand, if the balance shifts to the left, ET becomes higher then the precipitation, resulting in drought in the various severity. Taking the country as a whole, as per meteorological report, severe drought in large area is experienced once in 50 years and partial drought in five years while floods are expected every year in one part of the country or the other, especially during rainy season. In fact the balance of the equation is controlled by the weather, season, crops and cropping pattern. Out of 142 million ha of net sown area in the country, rainfed agriculture is practiced in 95 million ha (67%). Nearly 67 m ha of rainfed area falls in the mean annual precipitation range of 500-1500 mm.

9.1 Farm Tools and Equipment for Horticulture and Plantation Crops

Agriculture in India is one of the most prominent sectors in its economy. Agriculture and allied sectors like forestry, logging and fishing accounts for about 14% of the GDP and employed 60% of the country’s population. About 43% of India’s geographical area is used for agricultural activity. Despite a steady decline of its share in the GDP, agriculture is still the largest economic sector and plays a significant role in the overall socioeconomic development of India. Nearly 80 percent of the farm population operates smallholdings, the average size of holding being 1.16 ha. Out of a total geographical area of 329 m ha, about 142 m ha constitute the net sown area. Nearly 63 percent of this area is rainfed and its contribution to the overall production is 44%.

A farm tractor is a versatile, heavy-duty agricultural vehicle designed to perform a wide range of tasks on the farm. Tractors are a cornerstone of modern agriculture, and they come in various sizes, power ranges, and configurations to meet the diverse needs of farmers and agricultural operations. Tractors are used for tasks like plowing, planting, cultivating, harvesting, and transporting goods on the farm. They are indispensable tools that have greatly increased the efficiency and productivity of agriculture.

The choice of tractor type depends on the specific needs of the farm, the type of crops grown, the terrain, and the available budget. Farm tractors continue to evolve with technological advancements, incorporating features such as GPS guidance, advanced hydraulics, and climate-controlled cabs to enhance efficiency and operator comfort.

Introduction

Agriculture is a major sector in Indian economy. It is one of the biggest production sector contributing more than 20 percent of GDP for India’s economy. Its is the largest provider of employment in Rural India. Over 70 percent household depends on agriculture. Its provides raw materials to industries and market for industrial product(Kekane, 2013).

Therefore, agriculture is a main sector for the planning of social and economic development of the country. Rapid growth of agriculture is essential not only to achieve self reliance at national level but also for household food security and to bring about equity in distribution of income and wealth resulting in rapid reduction in poverty line (Shrivastava et al. 2010). Agriculture is considered as the biggest unorganized sector where large numbers of women are working for their livelihood. The farm women comprise a quarter of the word’spopulation . Women also make up 41 percent of the word’s agriculture labour force, a ratio which rises to 49 percent for low income countries (ILO,2018).

Women play an important role towards the growth of the agricultural sector and its other associated areas. They perform multifarious tasks in agriculture and its allied fields. They are playing an important role in most of the farm operation like land preparation, seed treatment, sowing, planting, weeding, intercultural operation, irrigation of crop, application of manures and fertilizers, protection of crop, harvesting, threshing, storage etc. There is hardly any activity in agricultural production, except ploughing in which women are not actively involved. In some of the farm activities like processing and storage, women are dominant so strongly those men workers numerically insignificant (Patil and Babus 2018).Naidu et al. (2020) found that 63 percent of women are engaged in sowing of seeds and transplanting followed by in harvesting operation (61%), wedding (59%), winnowing (27%), manure and fertilizer application (25%) on regular basis.

Today around 25% of rural population in India are between the age group of 15 and 29 (2001 Census).  The Tenth Five-Year Plan (2002-2007) has estimated that India's labour force will increase faster than the ability of the economy to create new working opportunities. The country is adding 2 million young people to the ranks of the unemployed every year. The Plan document estimates that open unemployment could be as high as 5% at the end of the Tenth Plan period, from 2.8% at present.  This is likely to entail tremendous costs, including social unrest and dislocation resulting with large number of youth are unemployed or underemployed.
 
In India and in many developing countries the majority of the work force is employed in agriculture. However, stagnating agricultural productivity and rural environmental degradation have made agriculture a last option.  As the environment on which their livelihoods depend becomes more and more degraded, rural youth face diminished prospects of employment.  Not only do these youth lack income, they lack a means of gaining respect and a sense of belonging in their communities.  Unable to find decent employment, youth often look for employment in the urban informal sector, with poor working conditions and pay.  But without training in skills suited to the rural labour market, these youth have few opportunities in rural areas.  Inadequately trained to compete successfully in rural labour markets, they often suffer worse levels of poverty and marginalization in rural areas.

India is on the move, but in part.  
For, the farm sector is lagging behind.
It may soon become a drag on the economy.
Hence, farm development requires renewed efforts,
Farm youth must get critical attention.
Matter brooks no delay.

Farming is still the only source of human subsistence. No alternative is in sight. This ancient family occupation has survived over the ages through a process of transfer from father to son, generation to generation. But, in recent times, with an unprecedented externalization of farming, and under the pervasive influence of Liberalisation, Privatisation and Globalisation, this process of transfer of occupational knowledge within the community is seriously dislocated. Also, the earlier institutional arrangements for formal education in farming like district agricultural schools, gramsevaks training units and farmers training centres have now disappeared. In the meantime, even as more rural youth are becoming literate, formal education system is seen to have shed all aspects of agricultural education. Thus, the rural drop-outs are missing both formal and informal orientation in farming since a comprehension of ‘modern’ farming is beyond the middle level farmers. As such, farm youth today are neither here nor there, with regard to farming.

Abstract

Extension and Advisory Services (EAS) are delivered by millions of extension professionals representing the public, private and civil society located across the globe and have been helping in addressing farmers’ needs over the years. However, public sector has been a major agency dealing with EAS in India and is facing several challenges and constraints to fulfill the demands of farmers on timely basis. The challenge today is to change the organizational culture to incorporate innovation as a core value and to institutionalize the emerging paradigms. Further, different strategies and measures need to be taken to ensure timely and quality EAS by reorienting extension priorities. This paper has highlighted on strengthening extension and feedback mechanism, improving research- extension linkages, capacity building, public-private partnership (PPP), developing infrastructure, mass media support and use of Information and Communication Technologies (ICTs) etc. to improve the efficiency as the time demands. The paper concludes that reorienting extension priorities is very essential with a vast network of various stakeholders by adapting effective approaches like utilization of social media, human resource development, PPP, farmer groups etc. during and post pandemic scenario. Further, empirical efforts are also needed to develop reliable, location-specific, participatory, gender-sensitive and inexpensive extension methodologies and materials to meet the emerging demands. Further, developing countries like India have to invest in terms of various resources like financial, human resource etc. for promoting higher productivity and sustainability through EAS.

Introduction

Farming system conceptually is an integrated set of activities that farmers perform in their farm with available resources and circumstances to maximise productivity and net farm income on a sustainable basis. The system approach suggest a judicious mix of enterprises and activities based on the cardinal principle of minimising the competition and maximising complimentarity taking into account the components of soil, water, crops, livestock, labour, capital, energy and other resources. With all the resources, enterprises and external forces interacting in the system, the farmer operate at the centre of the farm household to take decisions observing variability, profitability, stability and sustainability. It is not the technology alone, but a set of social, political, institutional and economical forces influence the decision making process in a farming system leading to a model or acceptable combination of enterprises for overall development of the farm household.

Though science and technology have played a vital role in finding out innovations in the farming system approach through addition of new enterprise leading to profitability; new technologies ensuring stability and sustainability, the basic philosophy of the approach based on set principles is being pursued since initiation of agriculture in the civilisation.

In general farming system approach is more of a thought, a movement, a philosophy than simply choosing enterprise or combination of so to improve upon the standard of living. The interaction of bio-physical and socio-economic values plays an important role in up-scaling farming system approach and the adoption behaviour largely depend on the human values rather than material gain.

With the changing scenario, several factors like increasing instability in production, market price, high cost of production inputs, labour and negative impact of climate change, degradation of natural resources directly or indirectly warrants the use of sustainable rather regenerating technologies, compatible and noncompetitive farm enterprises to bring in sustainability and enhancement in production and income. For more than a century, programmes and activities have been designed to address the vulnerability of rural poor and are often targeted towards improving agricultural practices as means of increasing productivity, efficiency and ultimately income. In majority of the TOT cases technology has taken the centre stage even though the basic fundamental question like ‘whether the farmer adopt the offered technology and, if they do, whether they do it in ideal combination and for a considerable length of time needed to produce designed result remains unanswered. More importantly, in general the technology in isolation can not be recommended to all categories of farmers operating under varying situations. On the other hand acceptance and continuity of the technology is a dynamic process and varies both with the quality of the technology being promoted and the adoption behaviour of the individual farmer.

Social research concentrates more on socio economic variables to find out effects of the events that take place in social system. The magnitude of variation in the variables assumes to bring variation on the effect. The variables relating to farmers of small farms are many and they are specific to farming system of the coastal ecosystem. Such variables were grouped under personal, social, economic, communication behaviour, marketing behaviour, farming behaviour and training. The sub variables under each heading were given in the following table.

Farmers' rights and advocacy are essential for the sustainability and advancement of agricultural communities worldwide. These rights encompass access to land, seeds, resources, and fair market conditions, along with the recognition of farmers' contributions to food security and biodiversity. Advocacy for farmers' rights involves mobilizing stakeholders, influencing policy, and fostering grassroots movements to ensure equitable treatment and support for farmers. This article delves into the historical context, key components, challenges, and effective strategies for advocating farmers' rights, underscoring the importance of a collective approach to empower the agricultural sector

Introduction

Farmers are the backbone of global food systems, playing a crucial role in feeding populations and maintaining biodiversity. However, they often face numerous challenges, including land tenure insecurity, lack of access to quality seeds, limited financial resources, and unfavorable market conditions. Recognizing and advocating for farmers' rights is vital to address these issues and support sustainable agricultural practices. This article explores the historical development of farmers' rights, their key components, the challenges farmers face, and effective strategies for advocacy, emphasizing the importance of collective action to empower the agricultural sector.

1. Introduction

Over the years, Agriculture Extension has been at the fore front within the delivery of adequate data to the farming community not just for increasing productivity however additionally to reinforce their standard of living. Keeping in-sight of the demand for agricultural growth, evolutionary modifications had been made in transfer of technology to succeed in the farming community effectively. The Information and Communication Technology (ICT) is one among the required counterparts which made the agriculture extension more realistic and quite interesting.

Developing nations like India are though capable to get self-sufficiency in food production after green revolution however they’re in risk to keep this self sufficiency as they are possibly to face food shortage in near future due to rapid population growth. Thus, the demand of continuous increasing population is often fulfilled with the assistance of ICT as a tool of revamping extension network of the country. ICT is an emerging tool for development of farming communities.

Information and communication technologies have unique feature that provide opportunities to harness them in ways which are extraordinary from traditional media. ICT provides two-way communication between rural communities and development organizations. ICTs also improves the capacity to look for information and increase the number of information available, provide quality information, reduces uncertainty and enhance market participation.

Agricultural practices have been undergoing changes over a period of time throughout the world. The intensive agricultural practices followed during the past four decades in our country resulted in food security and self-sufficiency. This was achieved through development of input responsive varieties coupled with use of chemical fertilizers and plant protection chemicals. Agriculture is an important sector for economic development in India. Crop production is an important income source for millions of farmers in some cases with few cropping alternatives due to ecological constraints. All over the world majority offarmers rely on pesticides and fertilizers to increase yields. Pesticide use in most Indian agriculture is an essential part of production technology. Therefore farmers in developing countries are perceived as overusing pesticides, both in quantity and quality, with mixtures of chemicals, known locally as cocktails, being the favoured form of application (Crissman et al., 1994).

The prosperity of any country depends upon the prosperity of its people. Food, clothing, shelter, health, education, security, roads, electricity and drinking water are the today’s basic needs. Farmers produce food. About 70 % of Indian population is engaged in farming. Therefore, prosperity of India would depend upon the prosperity of its farmers. This in turn depends upon the adoption of improved technology and judicious allocation of resources (land, labour, capital, machinery etc). Human race depends more on farm products for their existence than anything else since food and clothing – the prime necessaries are products of farming. Even for industrial prosperity, farming forms the basic raw material. To sustain and satisfy as many as his needs, the farmers include crop production, livestock, poultry, fisheries, beekeeping etc. in their farms. Earlier subsistence was the important objective of farming. Farmers took many activities such as planting of fruit trees in their farms or on the common lands just for the welfare of mankind without expecting anything in return. The kind of farming where subsistence and welfare of mankind were the main objectives is designated as mixed farming. Farming today is also a mix of enterprises. However, higher profitability without altering ecological balance is important in farming. A set of agricultural activities organized while preserving land productivity, environmental quality and maintaining desirable level of biological diversity and ecological stability is designated as “Farming System”. Here the emphasis is mainly on a system rather than on gross output.

In other words “farming system” is a resource management strategy to achieve economic and sustain agricultural production to meet diverse requirement of the farm household while preserving the resource base and maintaining high environmental quality. The farming system in its real sense will help to lift the economy of agriculture and standard of living of the farmers.

Introduction

Nature is dynamic; it causes inheritable changes in all living organisms. For thousands of years, farmer around the world have been selecting and conserving varieties of different crop plants that they cultivated. This process has generated a rich wealth of varieties in each crop plant, seen to be most abundant in countries near the equator and India is no exception. In the world there are Mega centers of biodiversity of which aware present in India, this is because in India, the different soils and agro-climatic situations are present, so Indian farmers grow a large number of crops. Generation of Indian farmers, with their continued selection and conservation, has created a rich wealth of varieties in many crops. Therefore India is the original home of many crops such as rice, little and kodo millets, red gram, moth bean, jute, pepper, cardamom, many vegetables and fruit species. These plants were identified from the wild, selected and cultivated by Indian farmers over hundreds of years. The present wealth of varieties in India includes both crops that originated in the country and those that were introduced from the other countries during the distant and recent paste are soybean, sunflower, oil palm and kiwi fruit.

The Indian economy is predominantly rural and agriculture oriented. In agriculture, 85% of the holdings are less than two hectares and the declining trend in the average size of the farmer holdings, poses a serious problem. Majority of them are dry lands, which depend on erratic monsoon rains. The rest of the area is cultivated with supplemental irrigation. The farmers concentrate mainly on crop production, which is invariably subjected to a high degree of uncertainly income and employment.

In India the cultivable land is 143.8 million hectares and there is very little possibility of extending it further. Therefore, to meet the requirement of food grains for increasing population, the only option open is through time and effective space utilization in agriculture. The time concept relates to increasing the intensity of cropping under assured irrigated conditions, whereas space utilization pertains to building up of vertical dimension through multi-tier cropping and farming system approach. Thus by making use of these time and space concept either in irrigated or in rained areas, the productivity per unit area per unit time can be substantially enhanced. Therefore the only way to increase an agricultural production in the small/marginal units of farming is to increase the productivity per unit time and area. This may be achieved of quicker maturing varieties with equal yields or by improving techniques of culture, fertilizer use, weed and pest control.

A ‘system’ is a set of interrelated, interacting and interdependent elements operating together for a common purpose and capable of reacting as a whole to external forces. It is unaffected directly by its own output and it has a specified external boundary based on the inclusion of all significant feedbacks. A ‘farm’ is a system because several activities are closely related to each other by the common use of the farm labour, land and capital, by risk distribution and by the joint use of the farmer’s management capacity.

Farming System Approach (FSA)

Farming systems refers deliberate raising of crops,forest and fruit trees, animals including fisheries, piggery and duck farming, sericulture, mushroom, on a given unit of land to increase the productivity and profitability, to upgrade natural resource base and to achieve overall improvement in the environment

The philosophy behind shifting from cropping system to the farming system mode involves

1. In situ recycling of organic residues including farm wastes generated at the farm to reduce the dependency on chemicals
2. Decrease in cost of cultivation through enhance input use efficiency,
3. Effective use of bye-products/wastes of one component for the benefit of other component/components
4. Upgrading of soil and water quality and bio-diversity,

Introduction

Global warming directly ref lects on rising sea levels due to melting of ice caps and natural expansion of sea water as it becomes warmer. Consequently, areas adjoining the coast and wetlands could be frequently flooded and the distribution pattern of monsoon rains may alter, through more intense downpours, storms and hurricanes. The meteorological data available at the Annamalai University, for the tail end of the Cauvery river delta region of Tamil Nadu State, India, shows that the average annual rainfall during the last 10 years segment has increased by 233 mm compared to the average of the previous 10 years segment (1588 mm and 1355 mm, respectively). In contrast, annual evaporation has reduced by 453 mm (2153 mm and 1700mm, respectively) (Kathiresan, 2011). The year 1990 was the hottest year in the last century with all other five of the warmest years in the century falling within the last 22 years. This trend indicates that f lash floods in wetlands and droughts in uplands have become more frequent. Such a changing climate warrants reinforcement of climate resilience in farming to protect the livelihoods of farmers and the biodiversity. The sub-project of the National Agricultural Innovation Project implemented by Annamalai University in Tamilnadu, sponsored by ICAR has identified three types of clusters in each of the four disadvantaged districts, based on the prevailing agro-ecology viz. wetland clusters, rainfed upland clusters and coastal shore farming clusters. The constraints for farming and livelihoods in these clusters are identified as frequent floods, inundation, drought, weed problems, crop failure, and lack of diversification (Kathiresan, 2009a and Kathiresan, 2010). Farming systems that would be resilient to such climatic and farming constraints designed through rigorous institutional and on-farm experiments (Kathiresan, 2007; Kathiresan, 2009b and Kathiresan, 2012) were disseminated for adoption by the farmers in these clusters.

Farm economic efficiency of a specific area is an important factor of productivity and growth, where resources are scare and opportunities for developing and adopting better technologies have lately declining. No doubt, conventional farming is risky and farmers are reluctant to invert heavily in crop production. Modest increments in productivity are no longer sufficient to justify the investment of scarce resources as farming sector is small scale and resource poor, but integrated farming system assumes greater importance for sound management of farm resources to enhance the farm productivity, reduce the environmental degradation, improve the quality of life of resource poor farmers and to maintained sustainability. Farming system refers to the farm wherein two or more enterprises are integrated with the farm resources for achieving the fuller utilization, realize maximum profit and stabilize returns.

Various components of farming systems are as under

1. Cropping system

A system is set of elements which depend on each other and interacting among themselves. Farming system consists of several enterprises like cropping system, dairying, piggery, poultry, fishery, bee keeping, etc. These enterprises are interrelated. The end products and wastes of one enterprise are used as inputs in other. The wastes of cow, dung used as FYM in crop production and straw is used as feeding material for cow. Bullock is used for field preparation.

Cropping system is an important component of a farming system. It represents cropping pattern used on a farm and their interaction with farm resources, other farm enterprises and available technology which determine their makeup.

Cropping pattern: means the proportion of area under various crops at a point of time in a unit area. It indicates the yearly sequence and spatial arrangement of crops and fallow in an area. It indicates the early sequence and spatial arrangement of crops and fallow in an area. Crop sequence and crop rotation are generally used synonymously. Crop rotation refers to recurrent succession of crops on the same piece of land either in a year or over a longer period of time. Component crops are so chosen so that soil health in not impaired.

In agriculture, crop production is the main activity. However, the income obtained from crops may hardly be sufficient to sustain the farm family throughout the year. Assured regular cash flow is possible when the crop is combined with other enterprises. These other enterprises or components are called allied components.

Background

Farming system is a complex inter-related matrix of soils, plants, animals, implements, labour and capital, inter-dependent farming enterprises. The farm is viewed in a holistic manner (multi-disciplinary approach). Farming system approach requires commonly homogenous type of farmers. It is an inter-disciplinary, participatory and bottom-up planning approach. It is an approach for developing farm household systems. It is built on the principles of productivity, profitability, stability and sustainability which complement component oriented approach to development.

A farming system is composed of several farm activities, such as cropping systems, horticulture, livestock, fisheries, forestry, and poultry, as well as the tools the farmer has at his disposal to raise these things profitably. However, a lot of definitions generally express the same concept, which is that it is a technique to achieve profitable and sustainable agricultural production in order to meet the varied needs of the farming community while sparing the natural resource base and environmental quality.

In India since ages, the dryland farmers adopted a kind of mixed farming involving traditional annual crops and livestock consisting of one or two cows / bullocks and few poultry birds. This traditional system though of small scale provided some kind of risk minimisation particularly in the years of scanty rainfall causing agricultural drought. (https://coabnau.in/uploads/1587050523_ Agriculturalheritage.pdf) Discouraged by their marginal impact on farm economy, dryland farmers switched over to the lure of ‘productive’ mono-cropping with certain commercial crops like cotton etc. The continuous mono-cropping resulted in impoverishment of soils and low crop yields which took farmers into the labyrinth of poverty.

The arid regions of India, spread over 3,17,090 sq. km account for 12% area of the country. The western Rajasthan carries the onus of nearly 62% of arid area. Dryland farming is the main occupation of the people in Indian arid zone. More than 70% of the population in the region is engaged in dryland farming on more than 90% of cultivable lands. The average farm family in Indian arid zone consists of 6-8 members possessing 4-6 hectares of land. The over-exploited fragile natural resources are predominantly under mixed farming - pastoral as well as arable. Farming is almost entirely rainfed in this zone with low and unstable yields.

Farming system is an integrated set of activities that farmers perform in their farms with available resources and circumstances to maximize the productivity and net farm income on a sustainable basis. The farming system conceptually is a set of elements or components, i.e., soil, water, crops, livestock, labour, capital, energy and other resources that are interrelated and interact among themselves. At the centre of the interaction lies the farmer exercising control and choice regarding the types of results of interaction. The income of cropping alone from small and marginal farm is insufficient now to sustain the farmers family. A judicious mix of any one or more of these enterprises should complement the farm income and help in recycling the farm residues / wastes. The selection of enterprises must be based on the cardinal principles of minimizing the competition and maximizing the complementary between the enterprises. Of late, the researchers on multidisciplinary approach greatly realized and started developing the various farming systems models in accordance with the agro-eco systems zones.

Farming System thus may be defined as a complex interrelated matrix of soil, plants, animals, implements, power, labour, capital and other inputs controlled in part by farming families and influenced to varying degrees by political, economic, institutional and social forces that operate at many levels. The farming system therefore, refers to the farm as an entity of inter-dependent farming enterprises carried out on the farm. The farm is viewed in a holistic manner and the farmers are subjected to many socio-economic, biophysical, institutional, administrative and technological constraints.

Start with a 1:2 molar ratio of vector: insert DNA when cloning a fragment into a plasmid vector. This ratio will vary with other types of vectors, for example, cDNA and genomic cloning vectors. The following example illustrates the conversion of molar ratios to mass ratios for a 3.0kb plasmid and a 0.5kb insert DNA fragment.

Abstract

FASTA, which stands for “Fast All”, is a sequence alignment tool developed by William R. Pearson and David J. Lipman in 1985. It is commonly used to identify similarities between DNA and protein sequences. FASTA employs a “hashing” strategy to locate matches for short stretches of identical residues with a length of k, referred to as k-tuples or k-tups. This method enables FASTA to quickly search large databases for sequence similarities, making it a popular tool for identifying homologous sequences, predicting gene functions, and analyzing evolutionary relationships. This chapter elaborates some basics of FASTA.

Maintenance

When an animal is being fed for growth, fattening, milk secretion or other productive function, a considerable part of its feed is utilized for supporting body processes which are vital, irrespective of new tissue or product is being formed. This demand for feed is referred to as the “Maintenance requirement”; because it includes the amount needed to keep intact the tissues of animal which is not growing, working or yielding any product. There would be tissue break down with the accompanying loss in weight, leading to undesirable consequences, provided such need for feed is not met.

The fasting catabolism

The fasting animal doing no external work and not producing in any way is still carrying on a variety of internal physiological processes, which are absolutely vital for life. Obviouslythe nutrients required to support theseinternal activities must come from the break down of body tissue itself. This destruction of body tissue is termed as the “Fasting catabolism” and this can be measured in terms of the waste products discarded through the various paths of excretion.

Energy catabolism of fasting

The energy expended in the fasting animal is converted into heat, which can be measured in direct or indirect calorimeter. For measuring fasting catabolism at its minimumvalue, it becomes imperative to eliminate all the influences leading to increase heat production above the minimum expenditure compatible with the maintenance of life in so far as possible. Such a minimum value is called “Basal-metabolism” or BMR.Theconditions essential fora true minimumvalue of fasting catabolism can most nearly be attained in human being are specified as following :
