The present study was undertaken to evaluate the yield gap through CFLDs on blackgram by the active participation of farmers with the objective to harness maximum potential of crops by demonstrating the improved technologies. Krishi Vigyan Kendra, Hamirpur (H.P.) conducted 88 demonstrations on blackgram (Vigna mungo L., Fabaceae) in 16.7 ha area during kharif 2016 and 2017 in different villages of district Hamirpur, Himachal Pradesh. Prevailing farmers’ practices were treated as control for comparison with recommended practices. During kharif 2016 2017, the average yield of blackgram variety Him Mash-I was recorded to be 6.31 and 7.54 qha-1 and that of UG-218 was 5.4 and 6.77 qha-1, respectively. The increase in average yield of Him Mash-I over control i.e. farmers practice (Local Mash) was 30.8 and 21.2 percent in 2016 and 2017while in UG-218 was 14.2 and 9.1 per cent over control for the respective years. The average technology gap in Him Mash-I was recorded to be 5.69 and 4.46 q ha-1 in 2016 and 2017, respectively and 4.60 and 3.23 q ha-1 in UG-218 in the corresponding years. The respective extension gap was calculated to be1.47 and 1.32 q ha-1in Him Mash-I and 0.67 and 0.57in UG-218 in 2016 and 2017. The technology index (%) was found to be 47.4 and 37.2 in Him Mash-Iand 46 and 32.3 per cent in UG-218 during kharif 2016 & 2017, respectively.
