The experiment was conducted to study the effect of insecticides and stages of insecticidal sprays on seed yield and yield components in greengram. The investigation was carried out in Department of Genetics and Plant Breeding, during Kharif 2012. The experiment was laid in factorial randomized block design (FRBD) consisted of 15 treatment combinations involving two factors with three replications. Among the five test insecticides, spraying of malathion @ 2 ml/l recorded significantly more number of pods/plant (20.75), pod weight (20.45g), seed yield/plant (3.17 g), seed yield/hectare (949 kg) and less percentage of infested pods (5.35%) as well as infested seeds/plant (2.66%). It was followed by nimbicidine and methyl parathion. Whereas reciprocal values for these seed yield parameters were noticed in the unsprayed control plants (16.13, 16.53g, 1.84g, 725 kg, 14.13% and 7.89%, respectively). Similar results were recorded in spraying of insecticides at 20 and 10 Days before harvest compare to 20 or 10 Days before harvest. Interaction effect between insecticides and stages of insecticidal spraying were found non-significant for most of the seed yield and quality parameters.
