Today, in many countries mobile phones are being used by farmers, not only as a person voice communication medium but also to provide access to  information through sending message service (SMS), multimedia messages service (MMS) and access to the internet. Across the developing world, there are programmes that give farmers access to research and best practices, weather information and market prices via SMS, Interactive Voice Response (IVR) or call centers.

The ICT enabled extension systems act as a key agent for changing current agrarian situation by improving access to information, sharing knowledge, providing incredible opportunities and enabling the empowerment of farming communities. In order to extend the benefits of ICT’s to the disorganized and disadvantaged farming sector, one of the road maps to achieve them are access of ICT’s to villagers through Mobile telephony.

The transfer of technology keeps the wheels of agriculture development moving. The existing transfer of technology mechanisms and extension programs are either slow or ineffective in bridging the linkages between the research community and the farmers. Information Communication Technologies (ICT) in agriculture is an emerging field focusing on the enhancement of agricultural and rural development. The advancements in ICT can be utilized for providing accurate, timely, relevant information and services to the farmers, thereby facilitating an environment for more remunerative agriculture.

In India, self employment has been recognized as an essential force of development in rural areas. It has emerged as a strategy designed to improve the socio-economic life and mainly focuses on extending the benefits of development to the poorest in the rural areas improving their standard of living and self-realization. SHGs in India are integrating the low income segments with rest of the rural community by ensuring them a better contribution in a more equitable share in the benefit of developments. These Groups are not only speeding up economic growth, but also providing jobs and improving the quality of rural life towards self-reliance. Self-employment needs a very wide ranging and comprehensive set of performance, relevant to all aspects of rural economy and covering rural people including skilled, unskilled and landless labours and artisans of Rural India. The Rural Indians put their entrepreneurial skills in all the rural development performance  but their economic status has not improved to the expected level. They have much potential, despite they are ignorant of converting their skills into reality.

e-SAP is one of the important emerging and efficient dissemination tool for agricultural pest management. e-SAP refers to electronic solution for  agricultural pest management. e-SAP is a ground – breaking application built on the backdrop of agricultural pest management. Its foundation lies on a unique platform that facilitates the storage access and transfer information between all stakeholders in agriculture. It enables rapid and delivery of farm data in various forms including multimedia to researchers, policymakers and other users in real time.

Web-education Technology

“Educating the people through web” this process is called web-education. The World Wide Web provides new opportunities and hopeful future for distance education over the Internet and the distance education is becoming a widespread used for quite a long time through Newspapers, Radio and TV. Now-a-days mostly the World Wide Web (WWW) getting vital role in distance education, e-learning and distance learning since the networking technologies are emerging very rapidly in the media dominant era. The connectivity of the internet to different kind of people around the world is increasing steadily, like TV and Radio. The World Wide Web and other Internet–based collaborative modern communication technology tools have significantly enhanced the ability to train and educate people electronically.

Information Technology can play an important role in disseminating agricultural information to the farmers by using various multimedia sources. Farmers are more desirous and anxious to get quick, accurate and authentic information in the changing scenario of agriculture at local and at global levels. Dissemination of the required and recent agricultural information to the farmers in scattered villages at the variegated geographical situation in India is very difficult task. Transfer of technology to farmers is not a one time exercise because new farm technology is being constantly evolved. A continuous flow of technologies in an appropriate manner is vital to provide quick benefit for the development of the farmers. There has been a technological explosion in the field of agriculture. This demands that the farmer has to know all aspects of technology prior to its adoption. Hence Interactive Multimedia Module (IMMM) has potential to reach the unreached.

Information and Communication Technology is ruling the world in all walks of life and access to mobile phones and internet facility is growing in India at a rapid rate in recent years. However, the access to internet based technologies have confined primarily to the urban areas. Rural communities have not been able to gain to the same extent from IT. As a means of agricultural technology transfer to farmers, information technology has had a limited impact.

Kerala State receives an average annual rainfall of about 3000 mm but with high variability. The demand for water in Kerala is mainly for drinking, agriculture, power generation and aquaculture as well as for prevention of salt-water intrusion. Currently 71 per cent is used for irrigation , 18 per cent for domestic use and the rest is for other purposes. However, Kerala is one of the States with lowest per capita water availability among the Indian states. Basak (1998) reported the per capita water availability in Kerala was only 69 per cent of that of the country in 1981 though the general perception is contrary to this.

The Indian agriculture is on the threshold of a second revolution. It is becoming increasingly clear that the next leap will come from the Information and Communication Technology (ICT). Even though ICT has developed very well, its penetration to the farming community seems to be very less. At the same time, it is difficult for the extension agent to personally attend the queries of every farmer individually. With the decreased number of extension workers, there is a need to use the latest technologies for delivering extension services.

Indian economy is basically an agrarian economy (Saxena, 2012) and the majority less literate and unskilled population living in rural areas does not fit into the employment market. Employing 55% of labour force, agriculture sector is a major employment provider (Chand, 2014). However, the seasonal nature of Indian agriculture leads to seasonal and cyclical unemployment. This situation can be altered by generating employment opportunities through nurturing entrepreneurship in agriculture (Rehman et al., 2012).

The prosperity and growth of a nation depends on the status and development of women as they constitute about 50.00 per cent of the human resource of the country. Women play a significant role in agriculture and allied fields. She also performs several management and decision making roles in farming and home making practices with her male counterpart and sometimes alone.(Sreenivasulu and Punna Rao, 2005). Khelkar (1995) found that 64.55 per cent had medium level of farm management followed by high and low 18.18 per cent and 17.27 per cent respectively.

Women hold up half the sky’ according to Chinese saying. This is true with the Indian scenario as well, since women make up half the country’s population. The rural women in India constitutes nearly 77.00 per cent of the total female population. About 79.00 per cent of rural women workers are involved in agriculture related pursuits as cultivators and labourers. Farm & home are integral parts in the rural society in India and the ‘house wifes’ in the farmstead often plays multiple roles as producer, entrepreneur, workers, consumers, and homemaker. Women are more sensitive than men to the extremes of poverty and its consequences.

World-wide, both in developing and in developed countries;family farming is one of the most predominant forms of agriculture. It includes a wide spectrum of farm sizes and types. In high-income economies, it ranges from very large land holdings that are easily cultivated by one or two family members with the use of labour-saving machinery and hired labour. In low-income economies,with small holdings of a few hectares or less and that are often oriented towards subsistence with low marketable surplus.

There are 437 tribes in India and Andhra Pradesh is inhabited by 33 tribes. Of these, 13 tribal groups  inhabit in high altitude zone of Visakhapatnam. Livelihood security is the ability of a household to meet its basic needs like food, health and shelter, basic education and community participation. Livelihoods can be made up of a range of on-farm and off-farm activities which together provide a variety of procurement strategies for food and cash.

The College of Food Technology was established in the year 1976 at Parbhani as one of the constituent College of VNMKV, Parbhani. Food Technology College involves the knowledge of application of different fields of food Science and also includes transfer of Food Science technology to the students to make them well equipped with knowledge and skills required for employment in public  and private sector.

In the semi-arid tropics, where small farmers depend heavily on rain-fed agricultural systems, variability in precipitation has a dramatic impact on crop production and livelihoods. Because small-scale agriculture depends on rain-fed cultivation, it is vulnerable to factors such as flooding and drought. Unfortunately, the frequency of unexpected heavy rainfall or flood events has increased in many areas of Africa, including Southern Zambia. About 75% of farmers in Zambia engage in small-scale farming, with an average farm size of 2 ha (VAM Steering Committee Zambia, 1998). Most of these farmers cultivate maize, which is a staple food in Zambia, and stable maize production and increased productivity are important both for food security and to provide a livelihood to farmers.

Tank irrigation is passing through a critical juncture in India today. Tank irrigation contributes significantly to agricultural production in India in general, and in Andhra Pradesh, Tamil Nadu and Karnataka, in particular. The tank irrigation system is one of the vast networks of thousands of water bodies that constituted a distinctive landscape which was medieval in origin but still the basis of livelihood in the dry Southern plains(Mosse, 2003, P-4). Tank is a small reservoir constructed across the slope of the valley to catch and store water during rainy season. Water is controlled by sluices attached to the tank bank and is delivered to paddy field by distributing channels. Tank is considered as a common property resource. The National Sample Survey Organization defines common property resources as the resources that are accessible to and collectively owned, managed by identifiable community and on which no individual has exclusive property rights (NSSO, 1999).

Cassava is one of the leading staple food crop which is consumed as food and rest is used in industries and as feed to animal. Cassava has the potential to increase farm income, reduce rural and urban poverty and help to close the food gap (Nweke et al., 2001). It is used in many sectors like food processing, textile industries, glucose production etc. Salem stands first in area and has about 650 sago and starch industries acting as a prime reason for the intensive area under the cassava cultivation in Salem also 60 per cent of the starch produced in India comes from Salem District alone. Nearly 200 products can be made from cassava which leads to implementation of several interventions in the district which helped in imparting knowledge on cassava value addition techniques and improve adoption. Present study was undertaken to analyse the perceived impact by focusing on the effect of interventions of CTCRI and TNAU among the women growers in enhancing group approaches and empowerment through entrepreneurship activities.

Sustainability issues have infused sanity in utilizing interventions without much damage to the environment. The wisdom of the practitioners, who had over generations developed their own eco-friendly practices, is being appreciated. Recent researches have aimed at documenting, rationalizing, and blending the Indigenous Knowledge with the so called Scientific or Western knowledge so as to take care of the sustainability issues. Many researchers have contributed to this pool of knowledge by documenting many of the technologies, crop wise, area wise and operation wise and so on.

Climate change referred as, a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods (IPCC, 2001). In other words, it is any long term conspicuous deviation from usual prevailing climate bringing variations in normal temperature, rainfall, atmospheric circulation with abnormal expression in extreme climate such as floods, droughts, extreme temperature etc.

In conventional agriculture, spatial variability over the landscape is ignored and fertilizers, herbicides, insecticides, fungicides etc. are applied at a uniform rate throughout the crop field. Precision Farming emphasizes on the infield variability which is first recognized, located, quantified and recorded, then managed by applying farm inputs  in specific amounts at specific time and at specific locations.

Livestock sector plays a vital role in the welfare of India’s rural population by acting as an important source of income and employment in the rural sector (Dastagiri, 2004). India possesses the largest livestock population in the world and ranks first with (520.6 million), and accounts for the largest number of cattle (world share 16.1%), buffaloes (57.9%), second largest number of goats (16.7%) and third highest number of sheep (5.7%) in the world (FAOSTAT) and sustaining all these in less than 5% of world’s and one-third of Asia’s agricultural land area (MOA, 2003).

The agricultural production is inherently a risky business characterized by seasonality; perishability and variability which make it susceptible to vagaries of climate and markets and thus farmers face a variety of agricultural risks. In response to these risks over a period of time, several risk management mechanisms have been evolved. Risk management strategies refer to ex-ante measures taken before such an event has taken place, whereas risk coping strategies are, ex-post strategies dealing with the consequences of the event (World Bank Report, 2005). Invariably, farmers use both ex-ante and ex-post strategies. It is interesting to note that so far agriculture risk management has been in terms of risk avoidance and risk reduction and mostly these risks are addressed at farm or production level. Currently there has been a shift in agriculture risk management from risk avoidance and risk reduction strategies to risk mitigation strategies. Similarly, there exist shifts from production to market orientation in agriculture. To understand this phenomenon involved, it is felt necessary to study the agricultural risk management behaviour farmers. Keeping this discussion as focal point, the study was conducted with an objective to assess risk management behaviour of farmers.

Rationale of the Study

Greens are the cheapest of all the vegetables within the reach of poor man, being richest in their nutritional value. The problem of malnutrition is assuming seriousness in the vulnerable groups viz., adolescents, pregnancy, lactation and school children, not because of poverty but because of ignorance, illiteracy and callousness of the people. The lack of knowledge especially on the nutritive value of these green leafy vegetables among the public in general is the main drawback in their lower consumption. (Jyoti, 2008)

Introduction

To meet the food needs of the burgeoning population, India will need to produce 300 million tonnes of food grains by 2020. At present more than 75% of the total food grains produced in the country are of rice and wheat. Use of nitrogenous fertilizers has contributed much to the remarkable increase in production of rice and wheat in India that has occurred during the past three decades. During the last half-decade or so while fertilizer N consumption is touching new heights, the production of both rice and wheat is showing a trend of plateauing.

Introduction

It is well-known that soil testing is agronomically sound, beneficial and environmentally responsive tool for monitoring the nutrient as well as pollutant status of soils, and also for making precise fertilizer recommendations for various crops and cropping sequences. Soil testing with associated plant and water analysis is the only tool known which helps to control soil fertility. Nutrient supplying power of soils, crop responses to added nutrients and fertilizer and amendment needs can safely be assessed through sound soil testing programme. Monitoring of soil fertility, against depletion and accumulation of certain elements in toxic proportions over time, is also possible through appropriate soil tests. This also helps to economize on cost of fertilizers and also in increasing fertilizer use efficiency.

Introduction

The Indian agriculture is very complex and carrying out multi-functionalities of providing food, nutrition and ecological security besides employment and livelihood for over 700 million people. Indeed, India has made a marvelous achievement in attaining self-sufficiency in food grain production after the introduction of Green Revolution which eventually resulted in maintaining all-time high buffer stock in warehouses of our country. Such rosy picture in production trends turned to be bleak in the past few years.

Introduction

“Non-monetary inputs are defined as those cultural operations which help to achieve high yield at no extra cost and whose cost does not change with the level of output”.
 
After the advent of green revolution, nutrient management has received the significant attention by farmer as well as researchers; as a result of which and coupled with the requirement for high yielding varieties, consumption of plant nutrient (N, P and K) increased tremendously. Variability was observed in fertilizer consumption between the states. 

Plant mineral nutrition is a sub branch of plant physiology which addresses issues on uptake of elements that plant needs to absorb from air or water or soil to grow and to live. Besides function of nutrient elements in plants, it also includes deficiency symptoms and how to address deficiency symptoms in a plant. Plant mineral nutrition and mechanism of uptake has two major aspects:

Introduction

Nitrogen (N) fertilization assured centre stage for enhancing food production in developing countries especially after the introduction of high yielding and fertilizer responsive crop varieties. Almost half of the human population relies on N fertilizer for food production (Ladha et al., 2005), and about 56 percent of the N fertilizer is used for producing rice, maize, and wheat (IFA, 2002). It has contributed an estimated 40% to the increase in per capita food production over the past 50 years (Smil, 2002). However, excess use of chemical N fertilizer may negatively affect surface water, as well as groundwater, and the atmosphere (through leaching and runoff) through volatilization of N (Galloway et al., 2008).

Water and nutrients are the most important, and readily manageable, variables for producing a profitable crop. Efficient management of water and essential plant nutrients is imperative for achieving sustainable agriculture and maintaining necessary increase in food production to feed the burgeoning population while minimizing economic losses and environmental impacts. Technology here can play a catalytic role in striking a common ground between these environmental and economic goals. Recent advances in sensor technologies indicate that efficient nutrient management in crop fields can be attained through the application of Precision Agriculture (PA)-based geo-spatial technologies such as global positioning system, geographical information system, remote sensing,

With the introduction of high yielding varieties and use of high analysis fertilizer in intensified agriculture under irrigation condition resulted in green revolution in our country. But continuous use of chemical fertilizer in indiscriminate manner without assessing soil also had adverse effect on productivity and environment. Though use of high analysis fertilizer ensured the high production but also resulted in acceleration of mining of native sources of nutrient. This has led to appearance of hidden hunger of several other essential nutrients and sustainability of our agriculture has become venerable.

Introduction
 
The major challenges in 21^st century are food security, environmental quality and soil health. Besides, shrinking land holdings and increasing cost of inputs in India merit adoption of scientific use of plant nutrient for higher crop productivity. The soil fertility and fertilizer use project initiated in 1953 following a study by Stewart in 1947 which was the first systematic attempt in India to relate the knowledge of the soils to the judicious use of chemical fertilizers. The soil testing programme was started in India during the year 1955-56 with the setting up of 16 soil testing laboratories under the Indo-US Operational Agreement for “Determination of Soil Fertility and Fertilizer Use”. In 1965, five of the existing laboratories were strengthened and nine new laboratories were established to serve the Intensive Agricultural District Programme (IADP) in selected districts.

Introduction

Phosphorus (P) is a major nutrient in crop production, but is also a major constraint due to its low bioavailability in soils. It is 11th most abundant element on earth’s crust and a  vital component of DNA, RNA, ATP and photosynthetic system and catalyses a number of biochemical reactions from the beginning of seedling growth through to the formation of grain and maturity. Many factors influence soil P availability like type of parent material from which the soil is derived, degree of weathering and climatic conditions.

Introduction

Increasing consciousness about conservation of environment as well as health hazards associated with agrochemicals and consumers’ preference to safe and hazard free food are the major factors that lead to the growing interest in environmental friendly forms of farming in the world. Organic agriculture is one such broad spectrum of production methods that are supportive to the environment. The basic requirement in organic farming is to increase input use efficiency at each stage of farm operation.

Indian agriculture has grown over past 50 years from subsistence type of farming to a market surplus one with the present food grain production above 250 million tones (Fig. 1) which was only 50 million tones in 1950. At the same time the country has struggled over the years to meet the fertilizer requirement. More than 50 per cent fertilizer consumption is imported.

Introduction

Crop production system includes the components like soil, climate and plant (genetic) material. Within a particular genetic make up of the crop, productivity of the system is limited either by climatic factors, that is, radiation, temperature and rainfall (water), or by inherent edaphic environment that govern the root development and consequent uptake of water and nutrients. Where soils are cultivated over long periods, the edaphic conditions reach at its low levels. When water, nutrients and CO2 are plentiful, yield is determined by radiation and temperature regimes during the growing season. However, under actual field situations, the yields are limited by factors other than climate, which is water and nutrients. These are not only limited in amounts but also are becoming costlier every year. It is, therefore, important that available fertilizers be used efficiently.

Introduction

Soil resource is as important as water for agriculture as it supplies nutrients to the plants and anchorage for stand and establishment. However, people least bother about its importance despite its role in food security and ecosystem services. Good quality soil is a prerequisite for sustainable crop production. The concept of conservation agriculture (CA) has emerged in the recent past wherein conventional practices are modified to reduce farming cost in addition to sustaining soil health. Improvement in the soil health is achieved by increasing soil organic carbon (SOC), aggregation, infiltration, and also reduction in soil erosion.

Introduction

Soil is a complex system consisting of physical, chemical and biological components. These components dynamically interact making it functional to sustain life. All life forms rely on soil microbial processes for their survival. Microbial diversity in the soil is greater than the diversity of any other group of organisms existing in the earth. Microbes as inhabitant of soil are responsible for diverse metabolic functions that affect soil and plant health (Table 1).

Introduction

Nano science is the study of the properties of structures of the size smaller than several hundreds of nano meter (nm). Nanotechnology consists in techniques for designing and manufacturing these structures as well as applications arising from these. The development of nanoscience and nanotechnology is in line with the trend towards miniaturisation. As nanoscience and nanotechnology developed, they make the barriers between traditional scientific and technological disciplines more permeable.

Introduction

Fertilizers in India, are mostly applied either through broadcasting, foliar application or using seed cum fertilizer drills. With the introduction of micro irrigation systems, the application of fertilizers along with the irrigation water became promising and is gaining momentum. The goal of fertilizer application through irrigation is to maximize the uptake rate of fertilizers in order to minimize the losses.

Introduction

Land serves as storage for water and nutrients for plants and other living organisms, but the land resources are limited. India has about 18% of world’s population and 15% of livestock population to be supported from only 2% geographical area and 1.5% of forest and pasture lands (Rao et al., 2015). The per capita availability of agricultural land has declined from 0.48 hectare in 1951 to 0.16 hectare in 1991 and is likely to decline further to 0.08 hectare in 2035. This decline in per capita land availability in the country is mostly on account of rising population (GOI, 2010). 

Introduction

India has predominantly agrarian economy with just 2.5% of the world’s geographical area, but has about 17% of its population. India’s population has increased from 361 million in 1951 to 1270 million at present: a three and half-fold increase in a span of 63 years. By 2020, India will need about 294 million tonnes food grains (Kumar, 1998). However, only 259.29 m t was produced in 2011–12 (Directorate of Economics and Statistics, Ministry of Agriculture, 2012), implying that about 34 m t additional food grains have to be produced from the same or even lesser land area.

Introduction

Out of the total cultivated area of 142 million hectares (M ha) in India during 2011–12, 100.2 M ha was under cereals (the word cereal derives from Ceres, the name of the Roman goddess of harvest and agriculture) and 24.8 M ha under pulses (splitting seed), the staple food grains in the country (Economic Survey 2013). There is very little scope of bringing additional area under food grains; on the contrary this may decline in future due to the land needed for civil amenities and industrial purposes.

Introduction

India is the largest producer, importer and consumer of pulses in the world, accounting for 25 percent of the global production, 15 per cent trade and 27 per cent consumption, being an inseparable ingredient in the diet of the vast majority of population. Since time immemorial, pulses have been cultivated on marginal and sub-marginal lands, which are characterized by poor soil fertility and moisture stress, and consequently their yield potentials have not been realized. Further, more than 90 per cent areas under pulses are rainfed.

Introduction
 
Soybean (Glycine max L. Merril) is the world’s most important oil yielding legume which contributes 25% of the global edible oil, about two thirds of the world’s protein concentrate feeds for livestock, poultry and fish. India ranks fifth in the area and production in the world after USA, Brazil, Argentina and China. The contribution of India in the world soybean area is 10% but to total world soybean production is only 4% indicating the poor levels of productivity of the crop in India (1.1 t/ha) as compared to other courtiers (World average 2.2 t/ha) which is a major cause of concern.

Introduction
 
Sugarcane is an important cash crop of India. Since 1930-31 the area of sugarcane in the country has increased by about 4.3 times and production by about 9.8 times because of the rise in productivity of sugarcane by about 2.28 times, however, during the last decade there is no perceptible increase in productivity of sugarcane in the country. The domestic demand of sugar is around 22-23 million tonnes annually whereas the production of sugar in India is about 26 million tonnes annually. Data on nitrogen use efficiency of sugarcane from 1998-99 to 2013-14 in India is depicted in Fig. 1 and 2 show a decreasing trend (Anonymous, 2015). However, the escalating price of fertilizers in the market has become a cause of concern to sustain the productivity of the crop.

Introduction
 
Cotton belongs to the genus Gossypium, family Malvaceae. Of the 50 species, only four are cultivated, namely, G. arboreum, G. herbaceum, G. hirsutum and G. barbadense. The G. arboreum and G. herbaceum are popularly known as the desi cottons. The G. hirsutum and G. barbadense evolved in the new world and are known as American or Upland (G. hirsutum) and Egyptian or Pima (G. barbadense) cottons. India is the only country in the world where all the four cultivated species of cotton are grown on a commercial scale besides hybrids (both inter and intra specific) in three distinct agro-ecological regions and wide range of soil types.

Introduction
 
In India, most of the agricultural soils are deficient in one or more of the essential plant nutrients required for raising healthy crops and harvesting potential yield. Acidity, alkalinity, salinity, anthropogenic processes, nature of farming, and erosion are the main factors that can lead to soil degradation either alone or in combination of more than one factors.
