Our exposure to wide variety of chemicals has increased markedly in the recent past. Most of these compounds are mutagenic as well as potential carcinogens. Emphasis is being laid to develop method for detection of environmental carcinogens so that their use can be avoided.

Despite the fact that mammalian cell structure and human enzymatic pathways differ from those in bacteria, the chemical nature of DNA is common to all organisms; this permits the use of bacterial test systems for rapid detection of possible mutagens.

The Ames test which was developed by Bruce Ames in 1970, at the University of California, U.S.A. is a mutational reversion assay employing several special strains of Salmonella typhimurium, each of which has a different mutation in the amino acid histidine biosynthesis operon.

S. typhimurium, the indicator organism, used in this test is the mutant strain that cannot synthesize histidine (His^-), lack the enzyme to repair DNA so that mutation shows up readily and has leaky cell wall that permit the rapid entry of chemicals. In addition, this S. typhimurium strain carries mutation enhanced plasmid, the combined effect of these characters increase the sensitivity of the organism to mutagenic treatments.

The term growth for bacteria and other microorganism usually refers to changes in the total population rather than an increase in size or mass of an individual organism. As the mechanism of conservation and dissipation of heat generated during metabolism lacks in bacteria, the enzyme system in bacteria gets directly influenced by temperature. The purpose of studying the bacterial growth curve is a) to become familiar with the population growth dynamics of bacterial culture and b) to plot a growth curve and determine the generation time of bacterial culture.

A number of methods are now available for measuring bacterial growth. Some important ones are

1)By colony counting or cell counting

2)By weighing the cells

3)By cell activity (turbidity method)

The science dealing with the measurement of size of any microscopically visible microorganism is known as micrometry which is based on the principle of physics. Before measuring a cell, the diameter of the microscopic field must be established by means of optic devices, namely an ocular micrometer and a stage micrometer.

a)Ocular micrometer : It is a circular disc that is placed in the eyepiece. The disc is graduated in to several small divisions marked from 0 to 100.It is placed inside the eyepiece of the microscope. The distance varies according to the objective of the microscope which can be easily determined by using a stage micrometer.

b)Stage micrometer : It is a glass slide graduated in 1 mm. Again 1mm is divided into 10 large divisions and 100 small divisions (10 x 10 = 100 divisions). These divisions are equally placed therefore 1 small division is equal to 0.01 mm or 10 μm.

Generally microorganisms are so small and colourless in their natural state that it becomes difficult to observe them clearly under microscope. Stains and dyes, which are colouring agents, are used by biologist for better understanding of the morphological and anatomical structures of the organisms under study. Stains are prepared with great care and specification to get satisfactory result, while dyes are not as exacting in their characteristics.

Dyes are of two types, natural and synthetic. The natural dyes are used for histological purposes, whereas the synthetic dyes for bacterial stain. Usually dyes which are derivatives of cyclic compound benzene of benzole, are prepared from one or more substances found in coal-tar, and so are called coal-tar dyes. Chemically dyes are organic compounds containing both chromophore and auxochrome groups linked to benzene rings. Chromophore group provides the compounds the property of colour and thus benzene containing chromophores are called chromogens. It has no affinity to combine with fibres or tissue and as such not called dye. For being a dye, compound should contain an auxillary group which provides the compounds the properties of electrolytic dissociation.

The dyes may be acidic, basic or neutral. The acidic dyes are eosin, acid fuchsine and picric acid whereas the basic dyes are safranin, methylene blue, crystal violet etc. The acidic dyes ionize to give the dye portion of molecule a negative electrical charge. They are salts of sodium, potassium, calcium, magnesium etc. The basic dyes ionize to give the dye portion of molecule a positive electrical charge and are salts of chlorides, sulphates or acetates.

4.1 From Soil

Soil contains varied group of microorganisms such as fungi, bacteria, actinomycetes, algae and protozoa. The type of nutrients available, moisture, temperature and pH of the soil determine the nature of microbial population in soil. Different laboratory techniques for isolation of microorganisms have been detailed in chapter-III. These are used in particular for the isolation of specific type of microorganisms. All the techniques adopted are just to segregate the pathogens/ microorganisms from the mixture of microbial population present in nature.

(a) Isolation of Fungi

Soil contains large number of fungi and constitutes a major place of microbial population. They can be isolated in pure form by following the methods given below:

Under natural habitats microorganisms usually grow in mixed populations containing several species. This is really a problem for microbiologists because a single type of microorganism can not be studied adequately in a mixed culture. In laboratories these populations can be separated into pure cultures. The pure cultures contain only one type of organism and are thus suitable for studying the cultural, morphological and biochemical characters of an individual species. In the present days there are several ways of developing pure cultures in laboratories. Some of which are as follows:

Microorganisms, being ubiquitous, are found in soil, air, water, food, sewage, on body surfaces as well as on degrading and decomposing substances. Their survival and continued growth mostly depend on an adequate supply of nutrients and favourable growth environments. The culture media (nutrients) consisting of chemicals support the growth of microorganisms in a given condition. They are devised in such a way that the organism should get all the nutritional requirements. These are usually prepared in laboratory by weighing and dispensing the individual ingredients. Generally, the common media contain both inorganic and organic nutrients; however, for the cultivation of large number of microorganisms, specialized media are required.

Basically the culture media are of three types: (1) Natural, (2) Semi synthetic and (3) Synthetic.

Microbiology is a branch of science dealing with the study of organisms which are too small to be seen clearly by unaided eye. Roughly the organisms with a diameter of 0.1mm or less, which can not be seen by the human eyes unaided, come under the domain of microorganisms.

Thus, the laboratory work dealing with the microorganisms needs special care to avoid infection and infusion for maintaining good health. In fact all microorganisms should be treated as potential pathogens. Thus, for working with microorganisms aseptic techniques must be followed by students as well as by the laboratory assistants and teachers.

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.

Farming System Development (FSD) is better perceived as a means of facilitating interactive links between the actors (Table-1) who play significant roles in the process. A system perspective is needed in designing and evaluating suitable technologies as well as in designing policy / support system that improve both productivity and sustainability. Considerable challenges do exist in modifying the conventional top-down orientation characteristics of extension services. This requires the fundamental principle of FSD i.e. interactive mode of operation.

Indian agriculture has the challenge of providing national as well as household food and nutritional security to its ever increasing population with the average size of land holdings shrinking due to increasing fragmentation. Modern agriculture is facing multiple challenges of plateauing genetic potential of major crops, declining productivity in vast tracts of rainfed/ dryland areas, ill-effects of green revolution technologies in all intensively cultivated areas, climatic aberrations etc., which is threatening the sustainability of the important agricultural production systems and national food security. The assets of a small and marginal farmer is of various kinds – a small piece of land, a homestead garden, few chickens and ducks, 1 or 2 cows/pig etc which has to be managed judiciously to sustain the production productivity and livelihood of the farmer. Farmers take decisions as to crop and livestock management given their access to knowledge and information, personal circumstances, and in the context of the broader socioeconomic, institutional and political environment. Under such conditions, some farmers are painstakingly trying to make a livelihood out of their small pieces of land. However, unable to produce sufficiently, some have sold off or leased out their land to big commercial farmers. Such farmers have become a daily labour or shared cropper in their own land, or even migrated to cities in search of livelihood.

To overcome the problems of small resource poor farmers under diverse and risk prone environments a more holistic, resource based, client oriented and interacting approach, popularly known as Integrated Farming System (IFS) has been developed. This system defines output as total biomass outcome of the system. Integrated farming system is a reliable way of obtaining high productivity with substantial nutrient economy in combination with maximum compatibility and replenishment of organic matter by way of effective recycling of organic residues/wastes etc. obtained through integration of various land- based enterprises.

Introduction

In India about 8.6 per cent of population enlisted in the category as ‘Scheduled Tribes’ under Article 342 of the Constitution of India, but they constitute almost 16 per cent of the poor. Lakshadweep is the most populous state with respect to proportion of tribal to total population (94.8 per cent) whereas, in Uttar Pradesh tribal population is lowest with only 0.6 per cent of the total. In Odisha tribal constitutes 22.8 per cent of total population. In India literacy rate of tribal is 59 per cent as against that of general category is 69 per cent. Tribal people are observed to be strongly associated with the forests, hills and remote areas, practising a unique life style, having a unique set of cultural and religious beliefs. Over the generations these communities have evolved time tested farming systems, which are purely subsistence in approach and are keeping pace in perfect harmony with nature. Over the recent few decades, however, population growth and lack of harmony between different agriculture and developmental policies have threatened these traditional agricultural systems for extinction. The encroachment of local Governments and private interests on forest and mineral resources has pushed the tribal groups on to increasingly degraded land, thus their survival became a constant struggle.

The primitive societies have passed through several stages of economic development everywhere in the world. Thus one can find the stages of food gathering, hunting and fishing, farming, etc. among the Indian tribes. The tribes living in the forests and hills usually earn their livelihood by means of food gathering, hunting and fishing. Such is the life of Kadar of Kerala, Birhor and Kharia of Bihar and other tribes. The tribes living in dense forests, full of wild beasts, live on hunting, such as the tribes of Naga, Kuki, Bhil, Santhal and Gond. The hunters leave the females to carry out household activities in the morning and return in the evening after hunting. In some tribes there is a usual custom of hunting collectively. The Nagas use spears, arrows and bows. The Bhils are very much specialized in shooting by arrow. The tribes living near rivers and seas usually earn their livelihood by catching fish. The hilly tribes rear the cattle, an example of which are Goojars and the tribes of Chamba. The Todas of Nilgiri rear buffaloes. Some tribes also carry out cultivation, but they are generally shifting from one place to another. So shifting cultivation is an intrinsic part of tribal system and tradition. Among the cultivating tribes are the Santhals and Gonds. Tribal groups mostly do not have land ownership and have a limited option to adopt agricultural operations in forest areas. Considering their sustenance Government of Odisha has passed an Act “Schedule Tribes and other forest dwellers Forest Right Act” in 2006. It permits ownership of tribals on forest land up to 4 ha. for forest use and subsistence agricultural activity without any penalty. Cottage industries, such as weaving cloths, preparing ropes and skins and utensils of different metals are prevalent in many tribes. The Kharia people are very much specialized to cottage industries. Their living standard is very poor in spite of their hard work.

Introduction

The challenge of increased food production to meet food security needs still persists 50 years after the start of the Green Revolution as population growth continues to increase in many developing countries. There appears to be no alternative but to increase agricultural productivity and the associated individual factor productivities (such as water, labor, nutrients, energy and capital) to meet the food demand by 2050 and to alleviate poverty and hunger. Thus, needs technological initiatives for further agricultural intensification. But already happening negative effect of crop production intensification on essential natural resources such as soil, water, biodiversity, and associated ecosystem services has forced agriculture stakeholders to search for novel initiatives that focus on sustainable production optimization rather than just intensification. Furthermore increased food supply is a necessity though not sufficient for eliminating hunger and poverty. What is important is who produces the food, has access to the technology and knowledge to produce it, and has the purchasing power to acquire it. Of the developing world’s 5.5 billion people, 3 billion live in rural areas – nearly half of humanity. Of these rural inhabitants, an estimated 2.5 billion are in households involved in agriculture, and 1.5 billion are in smallholder households (World Bank, 2008 and Herren, 2010). Poor farmers need low-cost and readily available technologies and practices to increase local food production and to raise their income. At the same time, land and water degradation is increasingly posing a threat to food security and the livelihoods of rural people who generally live on degradation-prone lands. There are several other key issues while relating the situation to Indian context.

Introduction

It is obvious beyond doubt that the climate is changing. Climate has also been changing in the past, but its rate of change has been unprecedented in recent past years. It is true that no one could stop the climate from changing, but could do a lot for mitigating some of its effects and formulate adaptation mechanisms to it. Agriculture, especially the small holder producers have been at the receiving end of the climate change effects, resulting into not only in the fluctuating and unstable productivity, loss of natural resources and consequent livelihoods, but also to their survival.

Climate change and food insecurity are two most pressing challenges human beings are facing today and has emerged as the biggest twin challenge of this century. There are evidences that the increase in greenhouse gases caused by human activities is responsible for global warming and consequent climate change (FAO, 2007). Under the six emissions scenarios the global average surface temperatures are expected to increase by 1.1°C - 6.4°C this century [IPCC, 2007]. Climate change has its impact on almost everything on the earth and so on the food production. The agriculture plays a very important role in the economy of most of the nations of the developing world. For India, agriculture is the base of nation’s economy, largely rainfed and dominated by smallholders (Singh 2008 and 2010). As per reports from a number of governments, non-government and intergovernmental organizations, the countries and agriculture especially practiced by smallholders are particularly vulnerable to climatic changes and they have least capacity to adapt to these changes. In most of the developing countries of the world, the agriculture is not merely a matter of cultural practice but it is the source of livelihoods of millions of smallholders and their dependents. Changing climate as predicted will not only affect the agricultural productivity but also heavily hit the lives and livelihoods of the smallholder families and ultimately lead to food insecurity to the concerned nation and the world (Singh et al. 2012). Business-as-usual scenarios of population growth and food consumption patterns indicate that agricultural production will need to increase by 70 percent by 2050 to meet global demand for food. South-Asian countries made tremendous progress in food production in 1960s, 1970s and 1980s. with an impressive growth of food production, India, Pakistan, Bangladesh and Nepal transformed themselves from countries with a chronic food deficit to countries that were almost self sufficient in early 1990s. Except Afghanistan, all these countries had exported some quantities of food grain in late 1990s. The dynamic growth in the agriculture sector has, however, recently been lost. Productivity of major food grains has slowed and has been decline for some crops (Kumar et al. 2008) with food production failing to keep pace with population growth (G. Rasul and A. Schild 2009). As a result, South-Asian countries are now finding it difficult to meet their population most basic food and nutritional needs and remain vulnerable to food insecurity (Tab.1).

Mechanization of agriculture is essential for optimal utilization of vital inputs for crop production system such as soil, water, seed, fertilizer, pesticide and labour force leading to higher productivity and reduced cost of production for greater profitability. Thus with the support of mechanization, the agrarian sector as an enterprise needs to become sustainable and economically competitive which coincides with the objectives of the Integrated farming System concept. Mechanization also imparts capacity to the farmers to carry out farm operations with dignity, comfort and freedom from drudgery, making the farming agreeable vocation for educated rural youth as well. It helps the farmers to achieve timeliness and precisely meter and apply costly input for better efficacy and achieve higher productivity with reduced application of inputs. Small and marginal farmers now make use of high capacity agricultural machines on custom hire basis to enjoy the economic benefits. As such, the broad subject of agriculture can be understood as production agriculture, which takes care the field operations in the crop production system for higher productivity and post production agriculture, better known as post harvest technology which looks for reducing the loss of produce and value addition for economic gains. The IFS outlines the need of sustainability for farmers with limited resources of land, water and economy while mechanization aims at maximizing the profitability in agricultural system with a commercial attitude. Since the availability of labour force during peak hours of need and hike in wage very often creates hindrance in production and post production agriculture, mechanization can be the right answer to harness the benefits of IFS approach.

Commercialization is essential for agricultural development, which, amongst other things, entails mechanization of agriculture to reduce the cost of production and to increase the yield of crops. In some instances, agricultural commercialization may take place even without mechanization. However, due to the ever increasing agricultural labor scarcity in developing countries, an extensive scale agricultural commercialization may not be possible without mechanization.

The various farm operations involved in crop production system are land leveling, tillage for seed bed preparation, sowing and planting, weeding and interculture, spraying, harvesting and threshing. The mechanization of all these operation has been appreciated by the farmers which are discussed in the following paragraphs.

The stages through which the commodity passes from harvest till consumption are considered as post harvest stages. Post harvest management is one important component of agriculture and is the key to make more food and nutrition available to people. In integrated farming system, varieties of foods are produced. However, if they are not stored properly and/or processed, there may be both quantitative and qualitative losses. The produce may be attacked by different extraneous organisms including microorganisms, birds, rodents, etc. These spoilage agents may impair the quality of food, degrade the nutritional value and even make the food unfit for consumption. Besides, value addition of the food produce is another area where the overall profitability of the farming system can be improved. Thus proper management of post harvest operations and value addition are very important.

Importance of post harvest management and value addition

It has been estimated that about 10% of the food grains and about 30-40% of the fruits and vegetables are lost every year in a country like India due to improper post harvest management and lack of value addition. New avenues to increase food production are being explored to meet the demand of growing population of the country. However, prevention of post harvest losses is one basic step that can be taken up to make more food available for the people. In addition, proper post harvest management and food processing can help in the following aspects.

Introduction

Honey bees are the most fascinating creature found in the nature and are very closely associated with our cultural heritage. They have been evolved with structural perfection and behavioral instinct to render their service as the best pollinator and enable to realize the potential yields of several cross pollinated crops under various agro-ecological situations. They are indispensable for human survival. The words of the great scientist Albert Einstein quoted below is very pertinent in this context “If the bee disappeared off the surface of the globe, then man would only have four years of life left. No more pollination, no more plants, no more animals, no more man”.(Thakur, 2011). Thus, starting from honey hunting since time immemorial to traditional bee keeping and its present transformation to scientific bee keeping has been a continuous endeavor of human for harnessing both direct and indirect benefits from bee keeping activities. Bee keeping has been a very popular agro based enterprise which does not compete with any resource of farming system rather acts as an integral component of Integrated farming system. Now-a-days it has not only attracted the attention of a diverse group of people, administrators and institutions for various purposes but also it has been the point of attraction of the rural poor and youth for their livelihood improvement.

Mushrooms have been part of fungal diversity for around 300 million years. A mushroom is a macro fungus with a distinctive fruiting body, which can either be epigeous (above ground) or hypogeous (underground) and large enough to be seen by naked eye and to be picked up by hands. They lack the green matter (chlorophyll) present in plants and grow on dead and decaying organic materials, as phytoparasite or in mycorrhizal association with plants. From these decaying substrate, they absorb their nutrition with the help of fine thread like structures (mycelium), which penetrate into the substratum and are generally not visible on the surface. After the mycelium has grown profusely and absorbed sufficient food materials, it forms the reproductive structure which generally comes out of the substrate and forms fruiting body, commonly known as mushroom. Mushrooms can be divided into four categories (i) Those that are fleshy and edible fall into the edible mushroom category i.e., Agaricus bisporus; (ii) Mushroom that are considered to have medicinal applications are referred to as medicinal mushrooms i.e., Ganoderma lucidum; (iii) Those that are proved to be or poisonous or suspected of being poisonous are named poisonous mushrooms i.e., Amanita phalloides; (iv) those in a miscellaneous category, which include a large number of mushrooms whose properties remains less defined. The toxic/poisonous species commonly referred to as ‘toadstools’ are objects of fear and distrust and have led to certain amount of inhibition and taboo towards mushroom consumption.

Use of mushrooms as food by man has been practiced since time immemorial and probably predates any historical records. The early civilizations of Greeks, Egyptians, Romans, Chinese and Mexican appreciated mushroom as delicacy, knew something about their therapeutic value, often used them in religious ceremonies. Greeks regarded them as strength food for warriors while Romans considered them as ‘Food of Gods’ and Chinese regarded mushrooms as ‘Elixir of life’. Much referred ‘Somrus’ in ancient Indian literature is actually a decoction of mushroom. Archeological and other accounts reveal that ancient man used mushroom in religious ceremonies. The Aztecs of South America referred mushroom as ‘teononacte’ (God’s flesh) and worshipped a group of mushrooms as being divine. The high esteem in which mushrooms were held in different civilizations is also indicated by the restriction of the use of many species to the rulers.

Currently 14000 mushroom species are known to exist. Of these about 50 % or 7000 species are considered to posses varying degrees of edibility and almost 3000 species from 31 genera are regarded as prime edible mushrooms. To date only 200 of them are experimentally grown, 100 of them economically cultivated, approximately 60 commercially cultivated and about 10 have reached to industrial scale production in many countries. Furthermore, about 2000 are medicinal mushrooms with varieties of health attributes. The number of poisonous mushroom is usually reported to be relatively small (approximately 1 %), but there is an estimate that about 10 % may have poisonous attributes while 30 species are considered to be lethal.

Introduction

Agriculture has been the joint venture of both men and women since the time immemorial. Women play a significant role in agriculture and are responsible for half of the world’s food production in most of the developing countries. According to International Food Policy Research Institute (IFPRI), women play a central role as producer of food, managers of natural resources, income earners and care takers of household food and nutrition security. Food and Agriculture Organization (FAO) studies also confirm that women are the mainstay of small scale agriculture, the farm labour force and day to day family subsistence. About 70 per cent of agricultural workers, 80 per cent of food producers and 10 per cent of those who process basic foodstuffs are women and thus making up more than two-third of the workforce in agriculture production. They currently account for 60-70 % of all food production in all the developing countries. Other than agriculture and allied sectors like dairy, poultry, fishery, goatery and sericulture, women are also skilled in handicrafts, wooden works and various other types of small enterprises which boost the rural economy. They are also involved in small scale enterprises like rope making, broom making, bamboo works. All women in rural areas, irrespective to their age, size of their family, size of land holding, caste and community, perform major agricultural tasks. The rural women form the most important productive work force in the economy of majority of the developing nations like India. Agriculture sector employs 4/5^th of all economically active women in the country and 48 per cent of India’s self employed farmers are women (Kumar, 2013). In present scenario, nearly 84 per cent of economically active women in India are engaged in agriculture and allied activities. In a study undertaken by DRWA (Directorate of Research on Women in Agriculture) in low land and rainfed rice in Odisha revealed that under low lying situation, women spent nearly 20 days in uprooting and transplanting, 10 days in intercultural operations and 20 days in harvesting and transportation. In up land rainfed rice women were involved for 40 days mainly in gap filling, weeding, harvesting threshing etc. (Arya, 2008). The rural women of low-income category and lower caste perform more work in farm related field activities while the women of higher income groups perform more work in post harvest processing like storing of food grains, parboiling, winnowing, preparing puffed rice etc. In tribal areas, women participate in all agricultural operations except ploughing. They are seen to do more hard work in the fields than men. Depending upon the socio-cultural variations among different tribal communities, Non Timber Forest Products (NTFPs) are collected by tribal women. They collect food, fodder, fuel, medicinal plants, building materials and other household materials. Every day during off seasons, they go to forest for collecting NTFPs and sell it in the local hats (market) for day to day expenditure of their family. Sal and kendu leaves are also collected by them for their livelihood support. Ladies are the decision makers in farming sector as well as on other domestic affairs because of their greater contribution of household income. Marketing of their produce and also other materials collected from forest by them are exclusively done by the women group. Tribes mostly depend on forest and forest products during the dry period of the year. Now-a-days non-availability of NTFPs has shifted women from self employed to wage employment.

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).
