Abstract:
The present experiments were laid out at farmer’s field in Lalganj Block of District Mirzapur, Uttar Pradesh to find out the efficiency of eco-friendly Integrated Pest Management (IPM) strategies against gram pod borer, Helicoverpa armigera (Hübner) in chickpea agro-ecosystem during Rabi season of 2013-14 and 2014-15. Among all the IPM modules, Module-2 (M₂) was found superior over all the modules. Results revealed that the minimum per cent pod damage was observed in M₂ (10.1 and 9.9% during Rabi 2014 and Rabi 2015, respectively). Maximum per cent pod damage was recorded in Module-8 (M₈) (24.8% during 2014 and 26.0% during 2015). The effect of these IPM modules was also observed on the yield attributes. Highest grain yield of 2289, 2317 kg/ha was recorded, respectively in M₂ followed by M₅ with 2106, 2182 kg/ha during Rabi 2014 and Rabi 2015, respectively. Thus the highest pooled Benefit-Cost Ratio was also recorded in M₂ (5.78:1) and M₆ (5.32:1) of Rabi 2014 and Rabi 2015, respectively.
