The present study was carried out the evaluating the performance of improved cultivars with scientific package and practices on production, productivity and profitability of Bottle gourd. Frontline demonstrations were conducted during 2015-16 and 2017-18 with evaluation the performance of Narendra Shankar Lauki-4 variety of Bottle gourd in Sattarkattaiya blocks of the district and record the feedback information of farmer’s. The results revealed that average yield of Bottle gourd under frontline Demonstrations were 297 and 311 q/ ha as compare to 256 and 260 q/ ha recorded in farmer’s practice and average yield increase of 16.01 and 19.61 per cent, respectively. It was observed that the benefit cost ratio (B: C) of recommended practice (FLD’s) were 2.10 and 2.15 as compared to 1.88 and 1.87 in farmer’s practice during consecutive years of study blocks. The average extension gap 46 q/ ha and average technology gap 61 q/ ha was recorded. Therefore, the results clearly indicates that the use of improved varieties and package and practices with scientific intervention under frontline demonstration programme contribute to increase the productivity and profitability of pulses in Bihar state.
