The storability experiment was conducted on onion seed of Arka Kalyan variety in the Laboratory of Department of Seed Science & Technology at College of Agriculture, Raichur. Onion seeds were primed with KNO3 (2%), ascorbic acid (50mg/L), alpha tocopherol (0.5%), glutathione (0.05%), combination of ascorbic acid, alpha tocopherol and glutathione (A+T+G) (0.5%+0.3%+0.05%) and chitosan (0.25%) and stored in polythene bag (700 gauge) under ambient condition for a period of 10 months. The results revealed that among the seed priming treatments, the seeds primed with combination of ascorbic acid, alpha tocopherol and glutathione (T6) recorded the highest germination, speed of germination, seedling dry weight and seedling vigour index (79.50%, 18.16, 15.78 mg and 1068, respectively) at the end of 10 months of storage. At the end of the storage period, T6 recorded lowest electrical conductivity and highest dehydrogenase enzyme activity and alpha amylase activity (0.556 dSm-1, 0.831 OD value and 17.56 mm, respectively)
