Abstract


The storage experiment was conducted for a period of  ten months (July 2006-May 2007) under the ambient (250C and 70% RH) and cold conditions (40C and 50% RH) in the laboratory of Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad, using chilli seeds cv. Byadagi dabbi pelleted with botanicals (Arappu leaf powder, pongamia leaf powder and neem leaf powder), chemicals (KH2PO4, KNO3, K2SO4 and captan + imidachloprid) in comparison with unpelleted seeds as control. Gum arabica was used as adhesive and wood ash as filler material for pelleting. The treated seeds were stored in 700 gauge polythene bags. Seeds pelleted with captan (3 g/kg) + imidachloprid (2 g/kg) stored in cold condition recorded higher germination (80.3%), root length (8.26 cm), shoot length (4.66 cm), vigour index (1033), seedling dry weight (0.172 g) and lower EC (0.845 dSm-1) followed by seeds pelleted with neem leaf powder at the end of the 10th month of storage period.
