Impact of different intercroppings in the management of pod borer, Helicoverpa armigera Hüb. in chickpea

Abstract

The effect of different intercropping on the larval population of gram pod borer in chickpea was assessed on the basis of pod borer larvae and yield (q/ha). The chickpea intercropped with coriander recorded minimum number of pod borer larvae per meter row and maximum yield (q/ha) of chickpea followed by chickpea + mustard, chickpea + pea and chickpea + linseed. All the intercropping combinations scored lesser population of pod borer and higher yield as compared to the chickpea sole crop.
