The study was conducted in Barpeta district of Assam where front line demonstrations on HYV of Toria i.e. TS-36 was conducted by Krishi Vigyan Kendra, Barpeta on farmers field. A total of 63 FLDs were evaluated to find out the yield gaps between demonstrated Toria var. TS-36 and variety grown by farmers. Yield attributes of both demonstration and farmers’ practice were recorded and their yield gap, technology gap, extension gap and technology index were analysed. Toria yield of demonstration variety (TS-36) registered 29.70 to 42.85 per cent higher over farmers’ variet. On an average technology gap was recorded to be 1.93 q/ha. While average extension gap was observed to be 3.51 q/ha. Average technology index was recorded as 16.07 per cent.
