Abstract:
The present study conducted on Demonstration of yield, profitability and cost economics of cluster bean var. MDU1 at farmers’ field under Ramanathapuram district, Tamil Nadu during the year 2015-16, 2016-17 and 2017-18. The objective of the present study is to assessing the performance of newly released high yielding variety and adoption of new innovation technology. The present study results revealed that yield of cluster bean var. MDU1 ranging between 128.80 to 132.35 q/ha with a mean yield of 130.45 q/ha when compared to farmer practices (90.52 q/ha). In the case of powdery mildew incidence registered the lowest range in demonstrated plot (1-6%) whereas it was recorded the highest in farmer practices (15-20%). The extension gap ranged from 38.8 to 41.45 q/ha. The technology gap of demonstrated plot ranged from 39.65 to 43.20 q/ha. Technology index of demonstration varied from 23.05 to 25.11 per cent. Regarding cost economics, net returns found to the highest in demonstrated plot for three years ranged between Rs. 21500 to Rs. 35400. Benefit cost ratio (B:C) recorded the highest ranged from 2.50 to 2.66 under demonstrated practice, while it was the lowest range from 1.84 to 2.18 under farmer practices. The demonstrated plot had exhibited 43.34 per cent mean yield enhancement demonstrated plots. Hence, demonstrated technologies have proved more remunerative and economically feasible and this will be extended more areas at Ramanathapuram district during ensuing season.
