Yield Gap Analysis and Impact Assessment of Rapeseed- Mustard through Cluster Front Line Demonstrations in Khowai District of Tripura, India

The present study was carried out by KVK Khowai Tripura to know the yield gaps between improved practices under frontline demonstration and farmers practice of rapeseed- mustard crops. The productivity ranged from 8.00 to 10.50 q/ ha with average yield under demonstration recorded 9.24 q/ ha under improved technology on farmers field as against a yield ranged from 5.50 to 6.50 q/ ha with a mean of 5.88 q/ ha recorded under farmers practice. However, in the demonstration plot the yield enhancement due to technological intervention was 36.21% over the farmers practice. An average net returns of Rs 18,644/- at demonstrations plot, while the average net returns from farmers practice is Rs 7046/-. The additional cost of Rs 5565/- gave additional net return; it is Rs. 11,510/- per hectare, respectively. The increase benefit cost ratio was also estimated; it ranged from 1.38 to 1.87 in recommended practices and 1.22 to 1.47 in farmers practice. An extension gap of 3.36 q/ ha was found between demonstrated technology and farmers practice, technology gap was observed 3.23 q/ ha, whereas technology index 24.86%. Therefore, CFLD of rapeseed- mustard was an effective for increasing the productivity and cropping intensity (%) of rapeseed- mustard and changing the knowledge, attitude and skill of the farmers. This created greater awareness and motivated the other farmers to adopt improved practices of rapeseed- mustard.
