Front Line Demonstration helps in speedy and wider dissemination of the improved proven technology to the farming community. The pod yield of cluster bean under demonstration plot was an average of 6600 kg/ha, while, in farmer’s local practices plot with an average of 5100 kg/ha. The pod yield was increased from 29 per cent over farmer’s practices. In control BCR is 2.3 and 2.6 is in treated. Hence to motivate the farmers for adoption of MDU 1 variety with ICM practice.
