Abstract

Studies show that there exists a gap between potential and production of oilseeds in the country and so is the case in the Union Territory of Jammu & Kashmir. Brown sarson is the sole member of the rapeseed-mustard group that fits well in the predominant paddy-oilseed sequence in Kashmir valley situated in the Northwestern Himalayas, that makes it a major rabi crop in the valley. The production however is still below potential hovering around 7.9 q/ha. The present study indicated an extension gap of 5.3 q/ha and a technology gape of 3.8 q/ha in brown sarson. Nearly 36% of the respondents attributed this to late sowing of crop, 20% to lack of awareness and 12% to lack of quality seed. Interventions including mechanization, supply of quality seed, frontline demonstrations, awareness programmes, processing and marketing facilities will be crucial in bridging the yield gaps in oilseed in Jammu & Kashmir.
