Abstract: The Cluster Frontline Demonstration (CFLD) on lentil var.WBL-77 was conducted by Krishi Vigyan Kendra (KVK), Kokrajhar to find out the grain yield, technological gap, extension gap, and economics during 2020-21 and 2021-22. In both year, lentil variety WBL-77 was used in the demonstration plot and considering local variety as check in the farmer's plot. The result of the study revealed that the yield of lentil was found to be 10.0 q/ha and 9.50 q/ha, respectively under the demonstration plot as compared to 7.0 q/ha and 6.50 q/ha, respectively under the farmer's plot and the yield increased by 42.85 and 46.15 percent, respectively during the year, 2020-21 & 2021-22. The technology gap, extension gap and technology index were found to be 2.0 q/ha & 2.5 q/ha, 3.0 q/ha & 3.0 q/ha, 16.6 % & 20.83%, respectively during 2020-21 & 2021-22. The net return (Rs. 31314.00 /ha & Rs.34074.00 /ha, respectively during 2020-21 & 2021-22) and Benefit Cost ratio (2.59 & 2.87, respectively during 2020-21 & 2021-22) were found to be highest under demonstration plot in both the years. The results depict that the seed yield of lentil in the Kokrajhar district could be enhanced by using lentil var. WBL-77 over local variety and CFLD could be an effective tool to minimize yield gaps.
