The present study was carried out by KVK Senapati, Manipur at eighteen villages covering an area of 180 ha to evaluate the yield gaps between improved practices and farmers practice of rapeseed- mustard crops. A total of 425 nos. of front-line demonstration (FLD)s were evaluated to find out the yield gaps between high yielding varieties of rapeseed- mustard and variety grown by farmers. The average yield under demonstration recorded 851.75kg/ ha as against an average yield of 566.12 kg/ ha under farmers’ practice. In the demonstration plot, the increase in yield resulting from technological intervention was 33.47% compared to the methods used by farmers. The benefit cost ratio ranges from 1.77- 1.89 in recommended practices and 1.51- 1.66 in farmer’s practice. The average extension gap, technology gap, and technology index were noted as 285.62 kg/ha, 371 kg/ha, and 29.37 percent, respectively. The study indicated that the yield of grain and economic returns were greater with the recommended methods compared to those used by farmers. Consequently, the rapeseed-mustard cluster front line demonstration proved effective in enhancing productivity and transforming farmers' knowledge, perceptions, and skills.
