Impact of seed coating with polymers and bavistin on seed quality and storability in tomato (Solanum lycopersicum L.)

The investigations were carried out at Krishi Vigyan Kendra, VPKAS, Almora, Uttarkashi during 2013–14 to explore the effect of seed coating with polymers and bavistin on seed quality and storability of tomato cv. VL Tomato-4. The seeds were coated with polymers, bavistin and polymers dyes- bavistin combinations and stored in polythene bags for 12 months. Seed coating with polymers pink @ 20 ml per kg of seed and bavistin @ 1 g per kg of seed (T₅) recorded higher germination (77.83%), seedling length (15.76), vigour index (1227), field emergence (76.12%), less electrical conductivity of seed leachate (1.511 dSm-1) and seed infection (5.30%) up to 12 months of storage as compared to control.
