The study assessed the yield gaps in black gram (Vigna mungo L) under rainfed farming situations in Mandi district of Himachal Pradesh. A total of 224 demonstrations covering 60.60 ha area were conducted consecutively for four years under Cluster Front Line Demonstrations (CFLDs) programme during kharif 2015 to kharif 2018. Improved cultivars of black gram viz. Palampur 93, Him Mash1, Pant U 19, and UG 218 were demonstrated along with integrated crop management technologies. The study revealed a statistically significant difference in mean seed yield between demonstration plot and farmer’s plot in all the demonstrated cultivars during all seasons under study. Overall, seed yield of 611 Kgha-1 with 22.69 percent higher productivity and average profitability of Rs. 30,264 ha-1 was obtained under the demonstration plot in the pooled data over the farmer’s practice. The technology and extension yield gap in pooled data under the four-year CFLDs programme was 874.18 Kgha-1 and 124.91 Kgha-1 respectively. The use of high yielding varieties with improved technology packages also enhanced water use efficiency. Overall technology index of 55.56 percent revealed satisfactory performance of technological interventions which can be further boosted in the region by bridging the gaps with more efficient research and extension services.
