Online published on 15 December, 2016. Abstract The laboratory experiment were conducted to study the influence of seed pelleting on storability of radish cv. Pusa chetki during 2014–2015 at National Seed Project, Seed Unit, University of Agricultural Sciences, Dharwad. In the present study fresh seeds of radish were first pelleted with micronutrients like ZnSO4 (@ 3 g/kg), FeSO4 (@ 2 g/kg), Borax (@ 2 g/kg) and ZnSO4 (@ 3 g/kg) + Borax (@ 2 g/kg) and pesticides like Imidacloprid (@ 2.5 ml/kg), Vitavaxpower (@ 2 g/kg) and control (unpelleted) along with a filler material (Talc powder @ 250 g/kg) and maida (Starch gruel @ 10%) as a binding material. Pelleted seeds are packed in polythene bag (700 gauge) and stored at ambient condition. Seeds pelleted with ZnSO4 observed the significantly higher germination (93.67%), longer root length (16.70 cm), higher seedling vigour index (2825) and seedling dry weight (0.715 dS/m) till the end of ten months of storage period. While, FeSO4 pelleted seeds recorded the lower germination percentage (91.54), lowest root length (15.81 cm), seedling vigour index (2653) and seedling dry weight (0.767 dS/m). Seeds pelleted with Vitavaxpower gave significantly higher germination (93.50%), root length (16.89 cm), seedling vigour index (2879), seedling dry weight (83.93 mg), lower EC (0.716 dS/m) and maintained good seed health throughout the storage period over control.
