ABSTRACT

Hydroponics is a plant growth system that provides a more precise control of growth media composition. It offers people the ability to grow food in places where traditional agriculture simply isn’t possible. As Fiji has a warm tropical climate, the development of the tropical fruit and vegetable industry through hydroponics farming to meet local consumption and export market is a lucrative opportunity. The potential for hydroponics farming is enormous and is in demand to sustain production at reliable and consistent level in Fiji. Potential areas for the setting up of hydroponic farms in Fiji include Savusavu, Nadi, Navua, Sigatoka Valley and Labasa. These areas have established theirlogistical status with the market. A wide range of commodities are grown through hydroponics technology which complements the need to harness the “too hot” and “too wet” weather of tropical Fiji. The pristine environment and availability of resources such as water and other hydroponic farming input are added bonus to establishment of such venture. Hydro nut Hydroponic farming system are constructed as simplest form made of bamboo and coconuts using coconut husk as a growing media and worm casting and humus tea are used as fertilizer. It offers some significant benefits over traditional farming, and as word about these benefits spreads, more people will turn to hydroponics for their agricultural needs. As hydroponics allows produce to be grown locally and requires fewer areas to import their crops, there is a reduction in both price and greenhouse gas emissions due to reduced transportation requirements. This saves time and produces healthier, disease and pest free, lusher plants in about half the time as traditional agriculture farming system.

INTRODUCTION

Backyard poultry production is an age old practice in rural India. Rural poultry farming in India contributes to about 40% of the national egg production. In ancient time poultry birds were reared for different purposes such as for its fighting ability. In old civilization, the cocks are known for their morning alarm and the selection is also done for these traits. Their fighting ability is more responsible for their spread than there nutritive value of the chickens. Backyard poultry farming is now gaining considerable momentum in the country and enables rural community to participate, in the economic, political and social sustainable development of the rural communities.

Backyard poultry farming is being recognized as important component of socio- economic improvement among the weaker section of society; specially rural youth, landless labour, small and marginal farmers. Backyard poultry generates self-employment, provides supplementary income with protein rich food at relatively low cost. Backyard poultry farming is the one among different enterprises in the present situation which gives some assured income to rural youths of the country. Before 1950, poultry keeping in India was largely a backyard venture. During last 3-4 decades Indian poultry industry has shown excellent growth. Poultry farming is a profitable venture as a means of livelihood and income prosperity for rural youth and farmers. The small and marginal farmers may choose backyard poultry farming alternative method for generating good income with their limited land and water use. Keeping in view of demand of poultry eggs and meat in the country and its potential for income and employment generation among rural youth, there is a need to increase the poultry production in the country.

INTRODUCTION

Livestock is an integral part of agriculture in our country. In the decade, India’s population has grown drastically by 13% to 1.2 billion people. Meeting the nutritional needs of this swiftly growing is a gargantuan challenge. Researchers and young farmers have an important role to play in the India Government strategy to relieve pressure on food resources. The dairy industry is a large and important sector in India. We are the highest milk producers in world and milk is an integral source of nutrition and household income. But per animal production is very low as compared to developed countries. The challenge is to improve production and reproduction of dairy animals. Indian farmers feed their animals with imbalanced ration. Supplementation of mineral and vitamins in feed not only improves health status but also in turn increase the income of dairy farmers. The economic contribution of dairy sector seems to be quite substantial in the agricultural economy as well as in the national economy. Keeping in view the growing importance of dairy sector in the changing national and global economic scenario, the dairy farming vocational training programs are organized in the Extension Center of LUVAS at Jind. To undertake this work, 856 young dairy farmers of the area who have successfully completed dairy farming vocational training programmes during the year 2010 to 2013 were selected for the collection of data.

ABSTRACT

Indian agriculture is an economic symbiosis of crop and cattle population. Millions of family dairy farming dominates India’s dairy industry, contributing 62 percent of total milk produced in the country. So, encouraging family dairy farming in rural areas is necessary to increase the milk production at national level and increase the socioeconomic status of landless and marginal farmer. In rural areas there is a major problem of milk marketing. In urban scarcity of quality milk, other side in villages especially faraway from city there is surplus milk and farmers are not interested to rear more dairy animals. Marketing of surplus milk is main problem because milk is a highly perishable item and farmers not having time and also due to less quantity of surplus milk (3-5 liter) they are not interested to go market. For this we can work in group and collect milk at one place from all members and one person go to market for selling of milk. Extra milk can be used to manufacture other milk products like ghee, peda, paneeretc by other member. Some members also engaged in other work like treatment of animals, collect information of different schemes from related offices. While engaging with rural communities, we recognised that village women are the primary caretakers of cattle and play a significant role in dairy farming. As a result, the Village Woman Dairy DevelopmentProgramme - an initiative focusing on empowering village women engaged in dairy farming. Benefits in dairy farming depend on cost of feeding, medicines, labour and income from sale of milk. Milk price is fixed and not in farmers control so we increase the income through reducing the cost of milk production. Approx 70% cost of milk production on feeding of animals. To reduce cost of feeding and medicine we fed balanced ration to dairy animals. Also reducing cost of production by feeding locally available unconventional feeds through total mixed ration feeding and urea mineral molasses block supplementation.

ABSTRACT

The present study was carried out to assess the knowledge level of dairy Entrepreneurs of Patna District and to find the co-relation between the socioeconomic variables and the training needs. This study was conducted by personally interviewing 100 dairy farmers, sent for training at B.V.C. Patna by different Agencies. Majority of the respondents (58.20%) had medium level of knowledge flowed by 26% respondents with high level of knowledge, while some of the respondents (15.80%) had low level of knowledge about dairy entrepreneurship. The study of co-relation between socio-economic variables and training need of the respondents showed that variables like education (0.469), social participation (0.500) and the knowledge (0.734) were significantly and positively co-related with the training need. Whereas variables like age (0.063) family size (0.193) and land holding (0.072) were found to be positively but non-significantly co-related with the training needs while, the caste (-0.093) was found to be negatively and non-significantly co-related with the training needs at 0.05% level of probability. Therefore it is imperative on the part of change agency to utilize the variables gainfully so as to give needed push to knowledge level in the area of Dairy entrepreneurship development.

ABSTRACT

Dairy farming plays a significant role in rural economy. It provides more avenues for increasing rural incomes and sustaining livelihood. Milk and other dairy products are a major source of protein and calcium for vast vegetarian population of India and demand is likely to double within a decade. Many of the educated youth in rural areas are going back to dairy farming as a natural choice with passion, getting involved deeply, continuously learning and innovating in the process. However these young and intuitive farmers face many challenges especially with regard to technical input and availability of green fodder round the year. In order to address these problems, this study was conducted in Muktsar district of Punjab. The young farmers selected belong to age group ranging from 24-35 years. Seventy percent of the respondents were graduates, among them 25 percent being technocrats. About 65 percent had medium family size (5 members). Eighty five percent of respondents had small land holding ranging from 5-8 acres. For majority of the respondents’ dairy was the primary occupation. Sixty percent of the respondents had obtained 45 day artificial insemination (AI) training from Dairy Development Board, Punjab and themselves did AI on their farm. Many (75 percent) had herd size of 35-40 animals. Majority of the farmers had hired labour for milking and daily care of animals with family members involved in management of the farm. Most of them (65 percent) believed in preparing their own silage and breed improvement. The study revealed that many educated youth in dairy farming were of progressive and scientific temper with entrepreneurship potential but were facing many impediments like low milk yield (4.5 – 6.5 kg/ animal/day), poor breed up gradation, green fodder shortage, a large number of services per conception (3 in majority cases) with artificial insemination (AI), low competence of veterinary service providers in remote rural areas in addition to high veterinary costs, difficulty in marketing milk from crossbred dairy cows due to low preference. It was felt that if sincere and sustained efforts were made by all the stakeholders involved, dairy farming had the potential for all round socio-economic development of rural areas.

ABSTRACT

Documenting the traditional knowledge system for technology development considers as the first step towards a sustainable agriculture. A study was undertaken in some villages of operational area of KVK, Nalanda district to investigate and document the traditional knowledge system of dairy farmers in the area of Breeding, Feeding, Health care and Management. The findings revealed the materials and practices related to animal husbandry from the study area. The majors among them were like use of Eucalyptus leaves in controlling Haemorrhagic septicemia (Gala ghotu), allowing animal to remain stand in mud for few hours, spread out tobacco leaf power on the infected part of FMD disease, applying brine solution on the animal’s buttock for the treatment of mastitis, feeding banana stem juice in order to controlling diarrohea in dairy animals. Papaya fruits fed to the cattle increases fertility in them, spraying of chhoa for controlling termites, incorporation of tobacco leaf, betel leaf and curry leaf enhances the shelf life of ghee at least by 2 months, use of Eucalyptus leaves in controlling Pneumonia in cattle.

ABSTRACT

Human resources are one of the most strategic and critical determinants of growth. A country cannot make rapid social and economic advancement unless it has enterprising people with necessary knowledge, skill and attitudes. Entrepreneurship development not only helps individual to become self reliant but also adds to wealth creation process, thereby paving the way to past growth and development of the nation. Rural entrepreneurship is required to capitalize on the opportunities available and to create job, mainly for rural youth and the farm family. In order to achieve this we are promoting mushroom production and processing as an enterprise for rural youths and farm family through their capacity building activities like training, consultancy, forward and backward linkages and to some extent by making available the much required inputs in the initial stages as the scenario of mushroom production in state is far from satisfactory. With the vast opportunities both at the international and national levels lying at the door steps of India, nothing less than a mushroom revolution in the coming decade will help to achieve the targets of nutritional security of people. During last year we have trained 215 farmwomen and youth in mushroom production and processing out of which 110 trainees started producing it at small scale and selling in the local market. Three villages of Patna district have been developed as “mushroom village” namely Sadikpur, Chaknawada and Mahmadpur. A sample of 100 mushroom growers of Patna district was taken for present investigation. All of them agreed that growing mushroom is a beneficial enterprise as it is capable of recycling agricultural wastes and generating employment opportunities. But, they revealed that important constraints in recommended practices of mushroom cultivation are spawn availability, perishable nature and marketing of mushroom in local villages because of poor infrastructural facility and lack of institutional finance available to them. So, in order to encourage mushroom Production at household level in villages, it is required to uplift farmers, initiating new applications, providing them with adequate marketing information and sufficient agri-business finance knowledge. Two of the most important problems in India, unemployment and malnutrition, will be addressed to a larger extent by promoting the cause of mushroom growing and its utilization as health food.

ABSTRACT

Agriculture is an important component of Indian economy contributing over 14% to the National GDP and employment to about 52% of the workforce. The small farm families form the backbone of Indian agriculture. The sustainability of small farms needs to be continuously supported with appropriate technologies and also with promoting off farm employment opportunities in the rural sector. The role of KVKs’ in preparing the next generation farmers’ through imparting training to update their knowledge and skills in modern agricultural technologies related to technology assessment; refinement, demonstration and training of extension personnel to orient them in the frontier areas of technology development. Sh. Narender Singh s/o Sh. Jagdish Rai, Graduate, 42 years old youth from Dharania Village came in contact with KVK, Fatehabad in 2008 and got training from this centre. He was motivated to diversify his traditional system of agriculture with integrated farming system of Dairy Farming, Vegetable, Seed production, inter cropping of Guar in cotton. He also used neem cake and bio control agents in poly houses for management of root knot nematode. He is recycling cow dung from the dairy farm and producing bio gas for domestic consumption with the diversification of farming system. The total expenditure was Rs. 5,55,645 and gross return was Rs. 13,63,100. The farmer benefit cost ratio is 2:45.

ABSTRACT

India is the second largest producer of vegetables in the world after China with an annual production of 162.19 million tonnes from an area of 9.2 m ha. The requirement of vegetables in the country has increased a lot to meet the nutritional requirement of an estimated 1200 million population expected by 2020-21. Although the productivity levels of vegetables have increased manifold, it would not be sufficient to feed the ever increasing population. Production per unit area of land, time and inputs can be increased by improving efficiency of the rate and extent to which solar energy is harvested for conversion to economic produce. In multiple cropping systems, the possibility of more efficient use of resources like sunlight, nutrient and water per unit area is higher leading to higher production stability. It can be very much successful in high imput requiring crops like vegetables. Intensive cropping involving multi-tiered vegetable crops like pointed gourd + elephant foot yam + cowpea grown on the single piece of land at the same time can generate profits up to Rs 1,30,000 per acre. India ranks first in the youth population. If the energy of these dynamic youth is properly utilized in the field of better agricultural practices, especially vegetable cultivation, it will help improve the national productivity of vegetable crops and generate employment as a whole. Thus, intercropping involving multi-storied/ multi-tier cropping system can serve as well-established practice for sustained supply of vegetables throughout the year through which rural youth can generate high income for sustainable livelihoods and increased per capita income.

ABSTRACT

India is one of the leading coconuts producing country in the world. Yet, it does not figure in the list of leading exporting countries of desiccated coconut. The study makes an attempt to examine the Economics of production and marketing of desiccated coconut. The study was conducted in Tiptur taluk of Tumkur district. The primary data was collected from the 10 desiccated coconut entrepreneurs from Tipturtaluk of Tumkur district of Karnataka. The study reveals that desiccated coconut units were utilizing 78.9 per cent of their installed capacity. The net return per tonne of coconut processed by desiccated coconut units was lakh Rs. 32.1, lakh Rs.81.1, and lakh Rs. 114.5 in case of small, medium, and large sized units respectively. On an average Rs. 144.01 lakhs was needed for the establishment of desiccated coconut unit. Out of which the investment on land (53.64%) was a major cost followed by machinery (26.15%), building (15.11%), and power installation (5.11%). The break even analysis showed that all categories of units had processed more than breakeven level. The investment made on desiccated coconut units was realized back within 2 to 3 years. The major constraints faced by desiccated coconut units were lack of skilled labor, limited market for desiccated coconut, higher requirement of working capital, and use of obsolete machines. Motivating the entrepreneurs to improve the quality standards, and modernization of desiccated coconut units need to be considered to improve the performance of desiccated coconut sector.

ABSTRACT

Sweet Corn (Zea mays var. saccharata var. rugosa) also called Indian corn, sugar corn, and pole corn is a kind of maize having high sugar content (12 – 15%). It is a very delicious and rich source of energy, vitamin A and vitamin C. It is consumed as raw, boiled or steamed green cobs/ grain. Cooked/ processed sweet corn has significant antioxidant activity which has been suggested to minimize the chance of heart disease and cancer. In addition to this, it is also utilized in preparation of soup, salad and other famous recipes. Besides green cobs, the green fodder is also available to the farmers for their cattle. It requires deep fertile and good drainage loam or sandy loam soil with neutral pH. It germinates best at the temperature range from 20^°C - 25^°C. Green cobs are harvested after 20 days of pollination during kharif but the days may accorded by season to season. It is ready to harvest in 70-75 days during kharif season and 105 – 110 days during rabi season. After harvesting, green cobs should be immediately transported to the cold storage in refrigerated trucks to avoid the conversion of sugar to starch because loses flavor at high temperature. Being a short duration crop (70-80 days), farmer can earn 2.0 to 2.5 lac rupees per hectare because it require less input i.e. water, manpower and other crop management practices. Therefore, it can generate a good employment for rural youthdue to high demand in hotels for preparation of various dishes.

The Indian food industry is poised for huge growth, increasing its contribution in world food trade every year. In India, food processing is gaining importance as now it is being considered as profit industry. The increased demand for processed food in the domestic market and Indian foods getting popularized in the global market has put food processing industry on high priority list by the entrepreneurs. Accounting for about 32 percent of the country’s total food market, the food processing industry is one of the largest industries in India and is ranked fifth in terms of production, consumption and export. The total food production in India is likely to double in the next ten years with the country’s domestic food market estimated to reach US$ 258 billion by 2015. The food industry in India has been attracting a lot of attention from foreign investors in the area of processing, development of infrastructure for storage and transportation and retail marketing and scenario is changing rapidly.

Marketers make consistent attempts to innovate tools and strategies to overcome the challenges they face in the business arena. Business innovations are broadly classified under two heads, namely Product / Service innovation. Marketers need to design creative solutions to overcome challenges typical of the rural environment such as physical distribution, channel management, promotion and communication. India’s rural markets offer a sea of opportunity. The urban rural split in consumer spending stands at 9: 11, with rural India accounting for 55 percent of private retail consumption. Indeed the market can be tapped with focused attention and strategy. Currently the Indian retail market is estimated at Rs. 13,30,000 crore and almost half of this growing retail market at present lies in rural India, which is a tremendous growth sector that needs to be tapped with care. This paper examines how the corporate sectors with their innovation and creativity tapping the Indian rural market with their retail marketing.

ABSTRACT

Rural youth are the future of the agricultural sector in the country. A rising number of rural youth are migrating to urban areas from villages in search of better employment as well as better life. They are migrating towards cities due to limited resources, weak infrastructure, and unemployment in rural areas. Thus, the number of young people in rural areas is falling and the exodus of rural youth means fewer small-scale farmers for today and tomorrow. Agribusiness may prove important tool to stop the exodus of rural youth from rural to urban areas. Agribusiness provides the various employment opportunities in the areas of agricultural inputs, crop production, agro chemicals, fruit and vegetable cultivation, agricultural marketing and processing of agricultural produce. Agribusiness helps in remunerative farming which increases the level of income, employment and living standard of people in rural India. The present paper will discuss the role and importance of agribusiness in attracting and retaining rural youth in farming.

ABSTRACT

In 21^st century, the world has turned into a global village. This herculean task has been made possible with the advent of ICT tools. When we think of ICT, the most omnipresent tool that comes in our mind is mobile phones. With the increasing rate of mobile phone penetration in the urban as well as in rural areas, it is now possible to connect the farmers leaving in the far-flung areas with the institutes, who are working for the betterment of farming community. Today, mobile phones play a significant role in everybody’s life, besides being an efficient way to stay connected with the family; it also paves a way to bridge the gap between the availability and delivery of agricultural inputs and agricultural infrastructure. Mobile phones provide basic connectivity, mobility and security to owners, it works using the radio spectrum, so no need to rely on physical infrastructure, requires basic literacy only, also its services are available in local language; short message service (SMS), multi-media service (MMS) and voice communication are the added benefits. It allows transfer of data which can be used in the context of applications for the purpose of health, education, commerce and governance. Mobile phones are increasingly affordable due to factors like increased private sector competition and innovative payment methods. Due to high access, its reach, good adoption and real-time interaction mobile phones offer efficient solutions to governments’ communication challenges. Mobile phones helps the farmers in agriculture decision making, as they provide information related to crops, weather forecasting, seeds, fertilizers, bio-pesticides, soil fertility, pest and disease diagnosis, demand and supply of agricultural products, different schemes and technologies. Mobile based initiatives like SMS services related to weather forecast, disease forecast, and market information are issued to farmers by different organizations like IFFCO Kissan Sanchar Limited (IKSL) and Reuters Market Light (RML). Farmers can raise queries related to agriculture and allied sectors using their mobile phone to a farmer call centre which has been operating in every state of India. There are many such initiatives, which are working to provide valuable services, and also it provides opportunities to further explore the potentialities of mobile phones as a tool for transforming the farming scenario of India.

ABSTRACT

The main function of extension is to bring a desirable change in human behavior. The extension workers, thus are essentially educators and their most important job is to communicate useful and practical research findings to the farmers in such a way that they understand, accept and adopt. In order to achieve this objective, the extension agencies are disseminating new technologies through different means including mass media like radio, T. V, and print media. Considering the wide areas of coverage, exposure and frequent use by people, the mass media such as television, newspaper and radio play an important role in the transfer of technology. Mass media are increasingly becoming a veritable instrument and tool for transforming agriculture. Hence, mass media play a vital role in agricultural extension. There is a gap between the agricultural researchers and the farmers. A lot of findings from the research institutions and laboratories are not used by the farmers, either because of the information did not reach them, or the received information was not implemented by them. To overcome this problem, mass media play a vital role in diffusing scientific knowledge among the mass. This is used to link researchers and extension workers and collecting the feedback from farming communities. Further, agricultural technology information acquired by farmers through mass media. Generally, the agricultural technology information includes techniques of applying fertilizer, insecticides and fungicides to crops, improved methods of cultivation and conservation techniques of planting, maintenance, harvesting and storage of crops. There are also new technologies of animal husbandry as well as processing and marketing various agricultural products. Hence, mass media is the most effective means of reaching people with new ideas and persuading them to utilize these innovations. The appropriate use can create knowledge and catalyze behavioral change among farming communities for better family farming.

ABSTRACT

ICT innovations are bringing new information services to rural areas on which, farmers, as users, will have much greater control than ever over current information channels. A greater opportunity to access the services of ICT innovations is crucial requirement for the sustainable development of the farming system, which is the demand of the time. ICT when applied to the rural and agricultural conditions can improve the linkages between research and farmer sub-systems. The variety of new ICT tools for agriculture is impressive, but the tools need to be placed in an overall context of agricultural information and service needs. By looking at the critical information needs of agriculture and farming communities, the focus should be on applicable and relevant ICT tools for the specific purpose to serve the rural community without compromising with their individual applications towards understanding of their overall role in promoting productive, equitable, and sustainable agriculture. Extension workers well equipped with the ICT can prove more efficient in gathering, storage, retrieving, adaptation and dissemination of broad range of information needed by farmers, thus transforming them from extension workers into knowledge workers. Emergence of such knowledge workers will result in the realisation of the much talked about bottom-up, demand driven technology generation, assessment, refinement and transfer.

ABSTRACT

This study critically examined the access of women farmers to Information and Communications Technology (ICTs) as against their male counterparts. The study was conducted Kapasiaupazila of Gazipur district. A total of 120 respondentswere selected using proportionate random sampling technique and interviewed through structured questionnaires. Data collected were subjected to descriptivestatistics, Chi-square and rank test. The results indicated that the women folk, despite their dominancein agricultural activities, were dominated in terms of access to and full participation in the use of ICTs. In terms of access to agricultural information through ICTs, it was evident that, people in the study area capture the advantages of increased number of ICTs to access information related to their farming business. Most of respondents valued ICTs as easy, fast and convenient way of communicating agricultural information and also allow more contacts among the farmers for family farming along with increase income of the family people in the community. Chi-square analysis on the relationship between socio-economic characteristics of the respondentswith their access to ICTs showed that age, education and innovativeness have significant relationship with therespondents’ access to ICTs. Kruskal Wallis rank test showed that there was a significant difference inthe gender access to and the uses of ICTs (P d” 0.005) with the male dominating the female gender. Chi-squareanalysis revealed that age and educational background and innovativeness of the respondents had significantrelationships with their access to ICTs (P d” 0.005). On the other hand religious/cultural barriers, language barriers and cost of possessing and accessing ICTs were the main reasons for gender disparity in gaining access to ICTs.

INTRODUCTION

According to the World Bank, youth present an opportunity for a sustainedeffort to participate in nation’s development process because they possess greaterenergy and potential and have the capacity to drive positive change. Stimulating growthof employment in the agricultural sector remains paramount priority in countries with alarge agricultural sector, as improvements in agricultural productivity can generatemore and better jobs in most developing countries (World Bank, 2008). Youth who possess non-farm skills are 1.4 times more likely to move out ofagriculture. Their age has significant role in favor of shifting out of agriculture, becauseoccupational mobility was higher among younger farmers (Sharma and Bhaduri, 2012). India has the largest youth population in the world. About 70 per cent of India’spopulation is below the age of 35 years, making India the youngest nation in the World. According to some estimates, the proportion of population under 25 years in India is 51per cent. Some experts refer to this large proportion of youth as “demographicdividend” because greater proportion of the population is young and in the workingage-group which can lead to economic growth. However, out of the youth population of460 million, only 333 million youth in India are literate and unemployment rate ishighest (10.6 per cent) among youth (CIA World Factbook, 2012).

ABSTRACT

Information and Communication Technology (ICT) has become one of the basic building blocks of modern society. Young people are the world’s largest resource in development. Forty percent of the world’s population is under 20 years of age while 66 per cent of the total population in the country is below the age of 35 and this youth play very important role in adoption of ICTs. Present study is concerning with Information and Communication Technology, importance of ICTs on youth and rural peoples of our country, the importance of ICTs is not the technology as such, but its enabling function in facilitating enhanced access to information and communication across large distances. It involved development and need of Information and Communication Technology. It also focused on strategies for sustained ICTs growth in India and development ranking of some selected countries. India has been ranked 121^st among 157 countries in terms of progress in the realm of information and communication technology.

ABSTRACT

Small holdings in developing countries have long been associated with poor farming practices, intensive labour and low income, which make the sector unattractive to a new generation of farmers. Lack of youth interest and involvement in agriculture affects the sustainability and survival of family farms. This interest in farming is further strengthened by ICT providing access to markets and information to boost production. Researchers found that youngsters easily grasp the ICT applications, acquire information, and jump onto new market opportunities. Considering the above facts the present paper will address the issue of the role that ICT can play in invoking the interest of youth in farming.

ABSTRACT

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

ABSTRACT

With the developing world still depending on agriculture to a great extent and rural people depending on it for their livelihood, it comes as no surprise that family farms have been the focus of development in recent times. Family farms have been legacy for most of the farmers and along with it being principal livelihood option for many, the increasing need of agricultural extension services for these farms become more important. But at the same time, the huge gap between the number of famers or farm households and the extension personnel is a reality. And to bridge this gap, Information and Communication Technologies (ICTs) can play a significant role. Another purpose it serves is making agriculture attractive to the young people engaged in farming, mostly by compulsion. ICTs like web portals, mobile phones and social media are the most popular and most widely used and can enhance the interaction among researchers, extension personnel and farmers. The youth today are hooked to the internet and their 1^st major activity on the web is social networking. Also, mobile phones are the most popular form of ICTs as has been proven by the sheer number of subscribers worldwide. And these tools, used appropriately, can change the whole structure of agricultural communication. ICTs can be an important part of communication strategies, connecting the youth to peers and professionals. It is true that the ‘apps won’t plough the fields’ but they will definitely help the youth do the job better. ICTs can prove to be a great catalyst in engaging agricultural community in family farms making agriculture attractive and sustainable again.

ABSTRACT

Information Technology includes computers and communication technology along with associated software. I.T. can be defined as the technology of creation, processing, storage, retrieval and transmission of data and information. Transmission of data and information between through local national, regional and global telecommunication channels are not new to us. Computer networks have been the real facilitators of data and information interchange in the individual and corporate levels. LANS and WANS are the good examples of it. Developing countries have a critical stake in how successfully they cope with the trade, environmental, energy, healthy, agricultural, industrial, population and other challenges facing them as they enter the information age. The World is experiencing an explosive growth of IT at the moment. There have been tremendous impacts of I.T. on the trade, commerce and industries of the globe.

ABSTRACT

A detailed survey was carried out in all the 19 rural blocks of Birbhum district of West Bengal. Pisciculture is a powerful income generating activity (IGA) by the women Self Help Group (SHG) members related to poverty reductionand employment generation for a vast section of the rural society. Self Help Groups are non-formal cooperatives that are causing a silent revolution in rural India through micro credit and various other economic activities involving women are the major change agents. Nearly, thirty thousand SHGs have been formed in Birbhum district of West Bengal that had made a notable success in micro finance. This study has focused on the functioning of 38 women SHGs of Birbhum district comprising 644 members mainly belonging to Below Poverty Line family. Totally 38 SHGs have been selected for the study. Each group had it unique name and consists of about 10 to 18women members. Information was elicited from all the members of 38 women SHGs, which together formed 644 members, constituting the study sample. The data were collected with the help of semi-structured interview survey schedule. The survey was carried out during the year 2009. Different social class of these fisher women members of the SHGs were assisted under Swarnjayanti Gram SwarojgarYojana. These SHGs were found to save a portion of their meager income and pool that money for their inter-lending among them at an interest decided by the SHG. The survey revealed that cash credit and project loan was used for better sustainability and enhancement of income from pisciculture. Most of the cultural water bodies i.e. ponds were under lease condition. Self Help group members particularly belonged to scheduled caste community actively take part in retail marketing of fish in rural areas. Empowerment of women was undertaken through training and other assistance given by local Panchayat, NGOs and Govt. Officials. The SHG women members increase in self-confidence, leadership qualities, skill to undertake pisciculture and marketing, knowledge of book keeping, enhanced income, linkage with bankand protest against social injustice.

ABSTRACT

Information is the data that have been put into a meaningful and useful context and communicated to a recipient who uses it to make decisions. Information is needed because of it affects individuals living activities. The present age has rightly termed as an ‘information age’. Information cannot provide finance, inputs or infrastructure. But, it can help in creating awareness about technologies and mobilise people to use them. It also helps in imparting training to people, organising community and ultimately the development of the whole nation.

The present study was undertaken to assess the information needs of young farm women (18-35 age group) with respect to kharif paddy cultivation. The study was conducted in Bolpur sub-division of Birbhum district, West Bengal. Results of this empirical study indicated that farm women wanted to know more about selling of product, pest control, nursery raising and disease management. The study also revealed that most preferred sources of information for the young farm women personal localite sources.

ABSTRACT

Women are vital human resources and play a significant role in agricultural and allied sectors undertaking both on-farm and off- farm activities. Yet their contribution has not been recognized and they are considered as invisible workers. Considering this, the present study has been conducted to analysis the constraints faced by farm women in agriculture and allied sectors. A total of 100 farm women were selected as respondents through proportionate random sampling. The selected respondents were interviewed personally using pre-tested well structured interview schedule. The finding showed that the major constraints that farm women faced were limited access to productive resources like land, credit, input, extension services, storage and technical assistance, their absence from decision-making process, less wages and their illiteracy also hindered their progress. Women perform all un-mechanized agricultural tasks and perform multiple tasks, which add more burden to them.

ABSTRACT

Agriculture can act as a catalyst in accelerating growth and reducing poverty. Agriculture can be an important engine of growth and poverty reduction. But in spite of its futuristic capabilities, the sector is underperforming because the productivity is reduced because of the constraints faced by the women in agriculture and allied sector. The women are the backbone of agricultural workforce but worldwide their hard works have mostly been unpaid. They have to perform most tedious and back breaking part of work in agriculture, animal husbandry and at homes. The tribal women play a significant and crucial role in agricultural development and allied fields including in the main crop production, livestock production, horticulture, post harvest operations, agro / social forestry, fisheries, etc. Tribal women have to manage, often, complex and multiple livelihood strategies. Their activities typically include producing agricultural crops, tending animals, processing and preparing food, working for wages in agricultural or other rural enterprises, collecting fuel and water, engaging in trade and marketing, caring for family members and maintaining their homes. Women’s participation in rural labour markets varies considerably across regions, but invariably women are over represented in unpaid, seasonal and part-time work, and the available evidence suggests that women are often paid less than men, for the same work.
