Krishi Vigyan Kendra functions as change agents to bring about desirable improvement in productivity of agriculture, animal husbandry and fisheries and enhance the income of farmers apart from creating employment opportunities. To achieve its mandate, as one of the methodologies, the KVK – CARI started adopting one or two villages at a time and implemented ‘Transfer of Technology (TOT) programmes, in an integrated manner so that a holistic development could be ushered in with an overall upliftment in socio-economical status of farming community as well as in production of food and profitability. Much emphasis has been laid on diagnosis of problem of farmers, developing their skills in improved technologies to mitigate identified problems, changing of attitude from unscientific to scientific cultivation and in management of farming systems, regular monitoring of the progress and assessment of impact for refinement and improvement and thereby achieving maximum sustainable development in all fields.
Krishi Vigyan Kendra, Bhadohi conducted 124 demonstrations on mustard variety - NRCHB-101, ND-8501, Pusa- Jagannath and Pusa –Vijai during two consecutive years from 2013–14 to 2014–15. The critical inputs were identified in existing production technology through meetings and discussions with farmers. Delayed sowing, use of higher seed rate resulting into dense plant population, uneven plant population, uncontrolled weeds, ignorance about fertilizers and lack of plant protection measures were the predominant identified causes of low productivity of oilseeds in district Bhadohi. In the same sequence the other parameters like technological impact, economical impact and extension gap were analyzed for Impact assessment of front line demonstration on mustard crop and feasibility of demonstrated technologies at grass root levels. The results of two years study revealed that the yield under demonstration plots was 21.50 q /ha as compared to 16.65 q /ha in traditional farmer practices plots. This additional yield of 4.85 q /ha and the increase in average mustard productivity by 29.13 per cent may contribute to present oilseed requirement on national basis. The average of technology gap, extension gap and technology index were found to be 9.27 q /ha, 3.05 q/ha and 34.63 per cent respectively. The results clearly indicate the positive effects of FLDs over the existing practices. Benefit: cost ratio was recorded to be higher under demonstrations against control treatments during the years of experimentation.
