Abstract: An experiment was conducted to study the effect of seed treatments on storability of onion seeds during June 2019 to March 2020 at National Seed Project (Crops), Dharwad, Post Graduate laboratory of the Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad. The seeds were treated with six different fungicides i.e Captan at 2 g/kg of seed, Carboxin + Thiram at 2 g/kg of seed, Carbendazim + Mancozeb at 2 g/kg of seed, Hexaconazole + Zineb at 2 g/kg of seed, Hexaconazole and Tebuconazole (each at 2 ml/kg of seed). Among the treatments, Carbendazim 25% + Mancozeb 50% WS at 2 g kg^-1 recorded better values of germination and seedling vigor index (70.33% and 659 correspondingly) at the end of nine months of storage. The results of this storage study concluded that seeds treated with Carbendazim 25% + Mancozeb 50% WS at 2 g kg^-1 fungicide recorded highest seed quality parameters in storage as compared to control.
