Impact of seed cum fertilizer drill on the yield of green gram in South Bastar, Chhattisgarh

The study was carried out during rabi season in four villages of South Bastar, Chhattishgarh during 2012–13. Frontline demonstrations (FLDs) on use of seed cum fertilizer drill for sowing green gram were carried out on an area of 5 ha by the active participation of farmers. FLDs recorded higher yield as compared to farmers’ local practices. The increase in yield, technological gap, extension gap and technology index were observed during the demonstrations. The improved technology gave higher gross return, net return with higher benefit-cost ratio than farmers’ practices.
