Description The greengram (mung) is an important arid pulse crop, its significance lies in crop rotation
and inter cropping as well on account of their ability to enrich soil by fixing atmospheric nitrogen and
healthy diet. The material comprised of two seed lots (good quality=L1 and marginal = L2) of each of
two popular varieties of greengram (Asha and Muskan). The different priming treatment (Hydration
14-16h, 2% CaCl2, 50 ppm GA3, hydration-dehydration+dry dressing with thiram @ 0.25% and 0.5%
KNO3) were applied to all the variety lots and combination to assess their effect on seed quality.
The significant mean sum of squares due to variety, lots and treatments and their interaction
indicated the presence of sufficient amount of variation for most of the parameters studied. Lot L2
seeds showed better improvement over lot L1 for standard germination, shoot length, dry weight,
vigour index-II, DHA, 50% flowering, days to maturity and yield. Whereas lot L1 showed better
improvement in root length, vigour index-I, EC, speed of emeregence, seedling establishment and final
plant stand. The variety Asha showed higher improvement in standard germination, shoot length, root
length,dry weight, vogour index-I, vigour index-II, DHA, 50% flowering, days to maturity , speed of
emeregence and yield. Muskan showed higher improvement in EC, DHA, seedling establishment, final
plant stand and 50% flowering.
Among various treatments hydration-dehydration + dry dresing with thiran @ 0.25% were
found most effective for improving shoot length, dry weight, vigour index-I , vigour index-II, DHA,
speed of emeregence, seedling establishment, final plant stand, 50% flowering, days to maturity and
yield followed by hydration-dehydration. Therefore, it is concluded from this study that the
germination level of marginal/ sub standard seed lots in greengram can be improved by using
presowing seed treatments.
