Yield Gap Minimization in Chickpea under Gangetic Plains of Eastern India
Keywords:
Chickpea, Cluster frontline demonstration, Pulses and Yield gap minimizationAbstract
Yield gap of chickpea will be minimized by implementation of suitable location specific agro techniques with timely and careful management. On farm cluster frontline demonstration (CFLD) on chickpea were conducted during rabi season of 2015-16 to 2017-18 in Buxar district of Bihar. CFLD was conducted in 20 ha area each with plot size of 0.40 ha (1 acre) with active participation of 50 farmers in two clusters. CFLD was conducted to popularize the demonstrated technology and quantifying the yield gap analysis in chickpea. Demonstrated technology under CFLD enhanced the plant growth and yield attributes. Seed yield of chickpea was recorded
higher under CFDL (15.51 q/ha) compared to farmers practice (11.81 q/ha) which was 31.32% higher over farmers practice, 40.81% higher over district yield (11.04 q/ha) and 42.81% higher over state yield (10.86 q/ha). Technology gap was recorded 2.75, 2.50 and 2.20 q/ha in year 2015-16, 16-17 and 17-18, respectively. Extension gap was recorded 3.83, 4.05 and 3.20 q/ha during 2015-16, 16-17 and 17-18, respectively. Technology index was recorded 23.75, 22.50 and 21 % during 2015-16, 16-17 and 17-18, respectively. Average net return of Rs 45700 was recorded in demonstration and Rs 29497 in farmers practice. The net return under demonstration was 54.93 % higher over farmers practice. Average benefit cost ratio of 1.73 recorded with demonstration and 1.15 with farmer's practice.
