In the present study 50 cluster frontline demonstrations each consisting of 0.4 ha area, on black gram crop were conducted during kharif 2022-23 and 2023-24 at farmers’ fields. Results of frontline demonstrations indicated that average yield of Vigna mungo L. under demonstrated plots where improved technologies like improved variety, seed rate, seed inoculation, optimum sowing time, land preparation, sowing method, fertilizer dose and technical guidance were demonstrated was 8.1 q ha-1 whereas the yield under farmers’ practice was 5.9 q ha-1. A considerable 34.4 and 41.6 percent increase in the yield of kharif blackgram in demonstrated plots was observed during 2022- 23 and 2023-24 over farmer practice plots. In addition to increase in yield of black gram, mean technology gap, extension gap and technology index was found to be 2.2, 2.1 q ha-1 and 29.0 per cent, respectively. It was further observed that in terms of economics, demonstrated blackgram plots fetched average net returns of ₹ 42,350 ha-1 with B: C ratio of 2.9 higher in comparison to farmers’ practice (₹ 24,600 ha-1 with B: C ratio 2.0). Impact of technological interventions in terms of productivity enhancement in kharif black gram reveals that demonstrated technology of blackgram gave average productivity by 46.7, 79.6 and 40.0 per cent more over district, state and national yield, respectively. Yield gap of black gram analyzed with average yield of district, state and national reveals that wide yield gap was observed in blackgram crop during study period. This yield gap can be narrowed down by encouraging the farmers to adopt sustainable technological practices for enhancing the production and productivity.
