An experiment was conducted at the Department of Seed and Science and Technology, College of Agriculture,UAS, Raichur to study the effect of repeated mid storage exposure to gamma irradiation and fumigation on seedlongevity of soybean (Glycine max) and green gram (Vigna radiata L.). The experiment consisted of seven treatmentswith different dosage of gamma irradiation and fumigation including control. Among the different treatments, significantlyhigher seed germination (89.8 and 71.4 %), germination rate index (7706 and 4702), peak value of germination (22.7 and12.1), shoot length (16.20 and 13.56 cm), root length (20.23 and 15.05 cm), seedling vigour index (3258 and 2051),seedling dry weight (0.409 and 0.323 g), dehydrogenase enzyme activity (2.632 and 0.319 OD value) and alpha amylaseenzyme activity (27.40 and 21.78 mm) with lowest abnormal seedlings (1.1 and 11.4 %), dead seeds (5.5 and 11.9 %) andmean germination time (1.59 and 2.51) was recorded by T7 (fumigation with aluminium phosphide @ 3 tablets / tonne ofseed) compared to all other treatments and control at one and four times repeated mid storage exposure to gammairradiation and fumigation. Whereas, seeds exposed to the gamma irradiation showed a significant reduction in seedgermination, germination rate index, peak value of germination, shoot length, root length, seedling dry weight, seedlingvigour index, dehydrogenase enzyme activity and alpha amylase enzyme activity with an increase in gamma irradiationdosage (200 to 1000Gy). While, the seed quality parameters such as, abnormal seedlings, dead seeds, mean germinationtime and electrical conductivity increased with increase in gamma irradiation dosage and also with repeated mid storagegamma irradiation and fumigation.
