Oilseeds are considered the second most important crop next to cereals, but there is still a huge gap in demand and supply. So, the production of oilseeds in India is considered to be of great importance. The programme Cluster Front Line Demonstration (CFLD) was initiated by Ministry of Agriculture and Farmer’s Welfare, GOI with the objectives to demonstrate newly released crop production, protection technologies etc at farmer’s field in cluster approach. Therefore, KVK, Golaghat, Assam had conducted CFLDs on sesamum. The present study was conducted to analyse the impact of CFLD programme with the parameters like changes of yield, income, extension gap and technology index with 175 nos. of beneficiary and 175 nos. of non-beneficiary farmers across 70 ha of area covering 12 villages of the district which were selected purposively during 2016-17 to 2021-22. Sample survey and PRA technique was followed for data collection. Proper statistical tools were used to analyse the data. The results revealed that there is an increase in average yield of beneficiaries over the years from 4.5 q/ha to 5.58 q/ha as compared to 3.4 q/ha to 4.34 q/ha of non-beneficiaries with the mean yield of 4.7q/ha (beneficiaries) and 3.41 q/ha (non-beneficiaries). The mean technology gap, extension gap and technology index were 4.96 q/ha, 1.08 q/ha and 49.60 per cent respectively which indicates need for improvement in extension services in educating the farmers for dissemination and adoption of improved technologies. The mean gross return (Rs.40, 650.00/ha), net return (Rs. 21,584.67/ha) and B:C ratio (2.1) were found higher in beneficiaries as compared to non-beneficiaries with mean gross return (Rs.31, 828.33/ha), net return (Rs16028.83/ha) and benefit cost ratio (1.9) Thus, higher benefit cost ratio proved economic feasibility of the improved technology demonstrated in the district.
