Krishi Vigyan Kendra (KVK) - Chirang is an innovative science based organization at the district level established by the Indian Council of Agricultural Research (ICAR) after recommendation of Mehta Committee (1973) with an objective of technology dissemination to the farmer’s fields without any transmission loss. The KVKs have been charged to take up the responsibilities of technology evaluation and impact assessment, demonstration of field technology on the farmer’s field, organizing training courses for the extension workers to update their knowledge level and skill training for the farmers including farm woman as well as rural youth. Objective of KVK - Chirang To demonstrate the improved technology to the farmers as well as to the extension agencies directly in the farmers field with their active participation.To identify the area specific problems of the farmers and prioritization of the identified problems as per their importance. To collect feed back from the farmers and extension agencies and to provide linkages with the scientists for the modification or refinement of the technology. To impart training to farmers, rural youths and extension functionaries for capacity building.To provide new and important information on agriculture and allied sectors to the extension agencies or NGOs for wider circulation to improve their economic condition.
Chirang is one of the major districts of Assam situated at the Northern part of Brahmaputra River under lower Brahmaputra valley zone of Assam. The district is situated in North-West side of Assam surrounded by international boundary of Bhutan in North, Bongaigaon district and a little portion of Kokrajhar district in South, Kokrajhar district in West and Baksa district in East. The geographical area of the district is 1923 sq. km. The district is located between 26.580 N longitude and 90.610 E latitudes. Rivers like Champawati, Aie and Manash are flowing through the district from North originating in Bhutan to the South and join the mighty river Brahmaputra. Besides many tributaries small rivulets and streams are flowing in the districts.

During 2019 she learnt about KVK Chirang from her neighbor woman who was the successful grower of mushroom cultivation and accordingly visited KVK office. When she interacted with KVK scientist, as per her interest on sericulture, scientist told the story about “The art of eri rearing, spinning, weaving is introduced by Bodo people in india . She was pleased and thought that she had stepped in the right place which will help her with low land. In due course of time she attended a number of training programmes on sericulture conducted by KVK. Then She started eri rearing activity by traditional way with 100 gm of eri seed
Ø Since sericulture activities were not new to her therefore she started his eri rearing activity with 100 gm of Eri eggs. And later on other technical support was extended by KVK and department of sericulture.
Ø Availability of eri food plant leads to year round cocoon production and hence castor, kesseru and tapioca plantation encouraged in farmer’s field by providing training on cultivation practices and providing of eri egg and mosquito net for proper scientific rearing under OFT and FLD programme
Ø Total income from Eri rearing Rs. 151000/-per yr and Net income Rs. 121000/-.
Ø Reduction of cost : Rs.45,000/- (Purchasing of food plant and eri egg is reduced)
Eri seed production, establishment of eri spinning and weaving centrewoman can make self dependent by adopting sericulture is a part time agri-business.

Since 2010, Mrs Mushahary used to cultivate field crops like rice, toria, potato etc in her field. She cultivated traditional vegetables in a small area. No scientific technology and good quality seeds were practiced in her field. She used to get annual income of about Rs 90,000.00 from field and other components. Although gradually she had diverted her mind to go for commercial vegetable cultivation, she faced problems like non availability of improved vegetable seed and poor technical knowledge. During 2019-20, she came to visit KVK, Chirang in search of potato seeds and thereby came to know about different high yielding varieties of vegetables and their improved cultivation technology from the scientists. She was very happy and interested to try it by herself.
Ø Skill training on scientific nursery raising of rabi vegetables helping her to produce early and disease free vegetable seedlings through which she is earning a good money.
Ø Demonstration on establishment of nutritional garden though input distribution including seeds, vermicompost, net etc. led her to systematic cultivation of a traditional kitchen garden
Ø Training on cultivation practices and providing seeds and fertilizers of biofortified cauliflower varieties Carotena and Valentena under OFT programme
Ø Demonstration on high yielding IIHR varieties like Arka Abhed tomato variety, Arka Sukomal frenchbean variety etc. from which she is getting good price in market.
Ø Technical guidance on planting material generation of areacanut, assam lemon etc.
Ø Technical guidance on value addition to local fruits and vegetables through skill training
Annual Turn over: Total income of Mrs Mushahary from her field is about Rs. 2,50,000/-per year which is 66% higher than initial income. She is recognized and awarded by District Administration also for her outstanding contribution towards farming. She has not only established herself with a good name but also become a role model to other rural women.
Slatted housed Goat farming: A way of self employment

• Mr. Jwngshat Basumatary after matriculation choosed goat rearing as income generating activity.
• The annual income of his family was around Rs. 2 lakhs which did not meet the family expenses.
• He came to know that the slatted housed scientific goat rearing is a beneficial enterprise.
• Now he rears a herd of 110 goats at his individual efforts
• Goat rearing is one of the important aspects in dry land farming system. In rural areas open grazing is a common practice for rearing of goat flocks.
• Due to the reduction in open grazing there is a need to search another alternate option i.e. stall feeding or slatted floor goat rearing method.
• Krishi Vigyan Kendra (KVK), Chirang conducted training programme on slatted floor goat rearing during 2019. He attended the training programme and came to know about slatted floor shed construction, breed selection, goat breed up gradation, green fodder production, concentrated feed production, disease management and market linkage.
• He initially started slatted floor goat rearing shed with 10 female local goats and 5 castrated goats.
• In the beginning he sold out the castrated male goats for meat purpose. Gradually he started producing crossbred beetal kids using Beetal buck which was provided by KVK under FLD programme.
• Male goat for breeding purpose are being sold for Rs. 12000/- at 4 month of age and Rs. 10000/- for female from his farm.
• At present he is maintaining around 60 adult goats & 50 kids in the farm.
• He is getting an annual income of Rs. 7,87,500 from the sale of 50 goats (9 months age) at an average weight of 10-12 Kg. He is selling FYM to other farmers also.
• KVK identified this goat farm as a model slatted floor goat rearing unit for KVK technical programmes.
• He started mixed fodder cultivation practices like Hybrid Napier, Fodder Sorghum, Rina grass, African tall maize for feeding goats and supplying seed and slips to other farmers.
• He established Mini Concentrate Feed preparation unit and also mineral blocks at farm level to reduce feed cost.
