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 farmersâ€™ 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 farmersâ€™ 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.
