Abstract: The present study was carried out to evaluate the performance of technological interventions like improved variety, line sowing, seed treatments with fungicide and biofertilizer, balanced nutrition and weed management on productivity and profitability of black gram. Black gam is an important kharif pulse crop in Sahibganj district of Jharkhand covering over 5218 ha with average productivity of 6.5 q/ha which is well below the state average (9.25 q/ha) and national average (9.7 q/ha). Unavailability of improved variety as well as non-adoption of improved cultivation practices in the district is one of the possible reasons for lower average productivity of black gram in the district. To enhance productivity of black gram through improved variety and cultivation practices cluster frontline demonstrations (CFLDs) were conducted during kharif season from 2016-17 to 2019-20. Performance of black gram variety PU 31 in 160 locations along with improved cultivation practices like line sowing, treatment of seed with fungicide and biofertilizer, balanced nutrition and weed management were evaluated in Barharwa and Rajmahal blocks of the district. It was observed that the yield of black gram in CFLD under rainfed conditions ranged from 9.48 to 9.60 q/ha whereas in FP it ranged between 6.35 to 6.53 q/ha. The per cent increase in yield with Improved Practices (IP) over FP was recorded in the range of 46.15 to 49.2. The extension gap and technological index were ranging between 3.0 to 3.13 q/ha and 26.15 to 27.07 per cent, respectively. The trend of technology gap reflected the farmer’s cooperation in carrying out demonstrations with encouraging results in subsequent years. The benefit cost ratio was 2.03 to 2.16 under demonstration, while it was 1.54 to 1.76 under farmer’s practice. Therefore, the results clearly indicate that the use of improved variety and package of practice with scientific intervention under cluster frontline demonstration programme contribute to increase the productivity and profitability.
