Context: KVK, is promoting and disseminating the knowledge and technical know-how about new varieties for the quantitative and qualitative production of farmers. Objectives: The study aimed to assess the impact of KVK intervention on the adoption of Yellow Sarson by the farmers. Methods: The study was carried out in Uttarakhand during 2018-23 in the operational villages of Krishi Vigyan Kendra (KVK), Kashipur, district Udham Singh Nagar. Data was collected using structured schedule developed based on the objective of the study. Statistical tools namely frequency, percentage, weighted mean and t-test were calculated to interpret the data. Results & Discussion: It was found that the seed average yield of Yellow Sarson was 12.65 q/ha in demonstration field as compared to seed obtained from farmers field (8.38 q/ha). The highest increase in yield was observed in the year 2022-2023 (64.70 %). The average pooled data results of the demonstrations conducted by KVK, Kashipur from 2018-19-2022-23 showed the average gross cost (Rs /ha), gross return (Rs /ha) and net return (Rs /ha) as 25000 Rs /ha, 61833.1 Rs /ha and 36833.1 Rs /ha, respectively. Benefit cost ratio (B - C) was found as 1.72, 1.82, 2.66, 3.22, 2.58, and 2.82 for the years 2018-19, 2019-20, 2020-21, 2021-2022, 2022-2023 and 2022-2023, respectively. An increase of 16.80 per cent has been found in demonstrations yield as compared with district yield. The substantial yield is attributed due to introduction of new variety in CFLD (Cluster front line demonstration) mode which facilitated better crop management. Significance: The study emphasizes the impact of KVK FLD programmes for the inclusion of new improved variety of Sarson and examines the extent of impact of extension activities in adoption of Yellow Sarson by the farmers.
