Cluster Frontline Demonstrations were laid out to upscale improved technologies for enhancing the productivity of blackgram during rabi 2022-23 which was 25 per cent higher as compared to farmer’s practices (6.4 q/ha). The study exhibited reduced mean extension gap (2.32 q/ha) and technology gap (5.07 q/ha) with lower technology index (42.58 %) due to the higher yield realized in VBN 11 demonstration plots. The average mean net return (Rs. 38049.5/ha) and mean B: C ratios (2.09) were higher in improved technologies than the farmers’ practices (Rs.21282.5/ha) and mean B: C ratio (1.57). The present study resulted in substantial increase in productivity and returns to the farming community through the adoption of improved technologies.
