OFT (ON FARM TRAIL) 13-14

With due consideration to meteorological information of the local area, its land situation, soil characters, socio economic conditions of the farmers and indentified problems of the area, kvk has conducted on farm testing (OFT's) on farmers field to solve some burning problems. In doing so, the technologies evolved from the laboratories and research station of SGCARS, Jagdalpur and other institutions were taken as probable solutions. The KVK conducted 62 on- farm trials from 2006-07 to 2010-11 involving improve technologies on various aspects of agriculture including varietals evaluations, nutrient management, cropping system/ farming system, resource conservation, weed management, insect/ disease management and organic farming management.
