Abstract
A study has been conducted in mung bean to determine the effect of different seed invigoration treatments for seed germination, seedling growing, flowering and development of pods. Two varieties of mung bean i.e., Gold and HUM-1L, were selected and seed had been treated with salt, GA3, CaCl2, KNo3, Urea and NaOCl respectively. Treated seeds were grown in different pots atAgricultural Research Farm, School of Agriculture, Lovely Professional University, Phagwara, Punjab. Seed invigoration with urea followed by GA3was found very effectiveforseedgermination with vigorous seedlings in both varieties, whereas seed treated with KNo3 showed negative effect on germination and vigorous growth. During it has estimated that the response for invigoration was vary for genotype to genotype for each treatment. Seed treatment with urea showed better performance than rest the treatments for all characters observed. The present results clearly elaborate that the germination, vigour and crop productivity of revalidated seed lots can be improved by pre-sowing and invigoration treatments.
