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.

The continuous rise in global population demands more food production under limited land resources accompanied by climate change. More oversupply of quality seeds to meet ever-growing food demand is a highly challenging task. Seeds with low vigour level limit the growth and yield of crops at varied field conditions. Hence, an experiment was conducted to develop a technique for the fast and homogeneous growth of kabuli chickpea seeds. The priming treatments evaluated in the present study enhanced the various seed quality parameters of kabuli chickpea significantly when compared to control. Hydro-priming for 4 hours (at 20°C) and air drying for 72 hours showed better results compared to rest of the treatments both in fresh seeds which recorded higher first count (66.38%), germination (92.50%) root length (11.85 cm), shoot length (6.16), mean seedling length (18.01), dry seedling weight (747 mg), seedling vigour index-I (1665), higher speed of emergence (0.3992) and old seeds with higher first count (61.88%), germination (74.13%) root length (8.15 cm), shoot length (5.85 cm), mean seedling length (14.00 cm), seedling dry weight (611 mg), seedling vigour index-I (1056), higher speed of emergence (0.3814). The aged seeds have recorded 29 % increase in germination percentage in contrast to 8 percent increases in fresh seeds. Kabuli chickpea seeds could be subjected to hydropriming, an affordable, alternative, and eco-friendly technique for improving seed and seedling vigour of kabuli chickpea.
