- Abstract
The pod borer (Helicoverpa armigera) is a major pest of chickpea accounting for 15-80 percent pod damage in the crop. The pod borer pest, collar rot, wilt and root rot diseases are major constraints to increase production in quality and quantity. The on-farm trial (OFT) was undertaken by Krishi Vigyan Kendra, Banda under judication of Banda University of Agriculture and Technology, Banda, Uttar Pradesh on the improved package and practices of chickpea in the district for the two consecutive years viz. 2018-19 and 2019-20 at the farmer's field, including control. Different Integrated Pest Management (IPM) components i.e. proper tillage, line sowing and inter cropping with mustard/linseed, HYV JG 16, Seed treatment by biopesticide i.e. Trichoderma spp. and Rhizobium culture for wilt and root rot disease management and better nodulations for nitrogen fixation, respectively. Management of pod borer insect through IPM approaches included installation of bird perches @ 50/ha, nipping before flowering, pheromones traps @ 20/ha, and spray of Azadirachtin (1500 ppm) @ 5 ml/lit at flowering time, spray of Indoxacarb 14.5% SC @ 500 ml/ha water at 50% flowering and at 50% pod filling stage during 2018-19 and same technology with Emamectin benzoate 5% SG @ 500 g/ha water at 50% flowering and at 50% pod filling stage were also comprised during 2018-19 under on farm trial. The performance of improved technology was found most effective in management least number of affected plants/m2 as well as least number of pods/plants in chickpea were recorded 17.5 and 4.4 per cent, respectively. The application of IPM strategies recorded mean grain yield of 12.15 q/ha, which was 14.90 per cent more over farmer's practice. The integrated approaches gave higher mean net returns of Rs. 46152/ha in chickpea, which was 34.96 per cent more over farmers practices. On an average benefit-cost ratio 2.36 was found under demonstrated technologies while it was 1.95 in farmer's practices. It was much encouraging to the farming communities and paved the way for implementation and evaluation at grass root level.
