According to Indian Institute of Pulses Research Vision document, India’s population is expected to touch 1.68 billion by 2030 and the pulse requirement for the year 2030 is projected at 32 million tones with anticipated required annual growth rate of 4.2 per cent. Pigeon pea occupies a prominent place in as rain fed crop in Jharkhand. To fulfill the domestic demand and to boost the production and productivity 275 cluster frontline demonstration (CFLDs) on pulse in Pigeon pea were conducted at 903 farmer’s field by Krishi Vigyan Kendra, Ramgarh from 2016-2020 in 110 ha areas. The district productivity (870 kg/ha) is below the average national productivity 904 kg/ha, although state average is 1002 kg/ha higher than national productivity. The study found that the yield of pigeon pea in CFLD under rain fed conditions ranged from 11.20 to 12.50q/ha whereas in FP it ranged between 7.20 to 8.90 q/ha. The per cent increase in yield with Improved Practices (IP) over FP was recorded in the range of 25.83 to 35.71 per cent. The extension gap and technological index were ranging between 3.1to 4.0 q/ha and 10.71 to 20.00 per cent, respectively. The trend of technology gap reflected the farmer’s cooperation in carrying out demonstrations with encouraging results in subsequent years. The benefit cost ratio was 1.9 to 2.6 under demonstration, while it was 1.7 to 2.2 under farmer’s practices. The present study resulted to convincing the farming community for higher productivity and returns.
