dc.description.abstract | Pigeonpea (Cajanus cajan (L.) Millsp.) is a major source of protein (22.3%), carbohydrates (57.6%) and fats (1.7%) to the vegetarian population. It also fix atmospheric nitrogen and maintain the soil in better physical condition and richer in nitrogen. Among the various factors responsible for low yield of chickpea as compared to potential yield, the losses caused by biotic and abiotic factors, out of biotic factors, insect pest are more prominent factor. The pigeonpea pod fly, Melanagromyza obtusa (Malloch) is one of the major biotic constraint in increasing production and productivity of pigeonpea crop throughout the country. Injudicious use of pesticides against this destructive pest, further ignites the problem of resistance, resurgence and environmental and ecological imbalances. Present investigation envisaged to study on population dynamics and management of M. obtusa (Malloch) in pigeonpea. Experiments were conducted at Students Experimental farm of Banda University of Agricultural & Technology, Banda. Various observations were recorded viz. population dynamic of M. obtusa, bio-efficacy of insecticides against M. obtusa, percent pod damage and grain damage, yield of pigeonpea and benefit: cost ratio. First appearance of pod fly was noticed in third standard week of the 2021. Throughout cropping period highest pod damage was recorded in eighth standard week and lowest pod damage was recorded in twelfth standard week of 2021. Emamectin benzoate + Dimethoate was the best treatment as it exhibited minimum pod damage and highest yield whereas highest benefit- cost ration were recorded with Dimethoate. | en_US |
