Abstract
The present study was carried out at five different villages of Kokrajhar district of Assam where cluster front line demonstration (CFLD) of High Yielding Variety (HYV) of rape seed (TS 46) was conducted by Krishi Vigyan Kendra, Kokrajhar. A total of 652 nos. of front line demonstration (FLD)s were evaluated to find out the yield gaps between HYV toria variety TS 46 and variety grown by farmers. Yield data of both demonstration and farmers practice were recorded and their yield gap, technology gap, extension gap and technology index were analyzed. The yield of rape seed variety TS 46 was registered 22.38 to 50.00 per cent higher over farmer’s variety. On an average technology gap, extension gap and technology index were recorded as 2.28qha-1, 2.08 qha-1 and 20.73 per cent respectively.
