The Cluster Front Line Demonstration (CFLD) programme on Sunflower was carried out during 2017-18 in operational area of Krishi Vigyan Kendra, Samastipur. The plots were selected from different villages/clusters (each of 0.2-0.4 ha) from the district. The variety ‘KBSH-44’ was used in both the demonstrated plots and farmers field. Fertilizer, herbicides, irrigation application and plant protection measures were taken as per improved package of practices. During the CFLD programme, it was found that the seed yield of sunflower was 12.06 q/ha in demonstration field as compared to seed obtained from farmers field (9.78 q/ha). The technology gap was found to be 5.94 q/ha. The 2.28 q/ha extension gap was found in that year. The technology index was 33.0 %. Higher gross returns (Rs 42210/ha), net return (Rs. 18370/ha and benefit-cost ratio of 1.77 were found in demonstrated field as compared to benefit-cost ratio of 1.42 in case of local check. The significant yield is attributed due to introduction of new variety in cluster mode which facilitated better crop management.
