Abstract: Storage studies were undertaken in greengram after pre storage treatments and results was performed better in seeds stored in super grain bag in all quality parameter compared to cloth bag during ten months viz., seed moisture content (9.32%), seed germination (80.8%), mean seedling length (24.47 cm), mean seedling dry weight (218 mg), seedling vigour index-I (1984) and seedling vigour index-II (1681), electrical conductivity (0.694 dSm-1), total dehydrogenase activity (1.433 A480nm), seed infection (17.57%) and seed infestation (7.52%). Among treatments studied deltamethrin @ 0.04 ml/kg seed recorded seed moisture content (8.15%), root length (9.41 cm), mean seedling length (26.97 cm) mean seedling dry weight (237 mg), seedling vigour index-II (1929), electrical conductivity (0.611 dSm-1), total dehydrogenase activity (1.600 A480nm), seed infection (8.50%), seed infestation (1.67%). Whereas, spinetoram @ 0.40 ml/kg also recorded better in seed germination (84.3%), shoot length (17.58) seedling vigour index-I (2244) at tenth month of storage. Interaction between packing material and chemical seed treatments on quality parameters were observed as seed germination in P1T3 (87.0%), mean seeding length in P2T2 (28.13 cm), mean seeding dry weight in P1T2 (257 mg), seedling vigour index-I in P1T3 (2356), seedling vigour index-II in P1T2 (2079), total dehydrogenase activity (1.686) (A480nm) and lowest seed moisture content in P1T3 (8.12%), electrical conductivity in P1T2 (0.581 dSm-1), seed infection in P1T3 (8.00%) and seed infestation in P1T2 (1.67%) at tenth month of storage.
