Effect of seed coating, storage periods and storage containers on soybean (Glycine max (L.) Merrill) seed quality under ambient conditions

Abstract
Soybean seed is classified as “poor storer” as it loses viability under warm and humid conditions and is invaded by storage fungi. The seed of soybean variety PS 1347, obtained from Breeder Seed Production Centre, G. B. Pant University of Agriculture and Technology, Pantnagar was used for storage study. Root length (cm), shoot length (cm), seedling fresh weight (g) and seedling dry weight (g) decreases with the increase in seed storage periods. Out of all chemical treatments, Flowable thiram @ 2.4 ml/kg (T2) and Polymer + vitavax 200 @ 2g/kg seed (T5) were found effective to maintain Seedling root length, shoot length, seedling fresh weight and seedling dry weight by producing vigorous seedlings. Seeds stored in cloth bags exhibited higher seed infection than in seed stored in polythene bags, irrespective of seed treatment and period of storage. Treatment T4 (Vitavax 200 @ 2 g/kg seed)and T5(Polymer + vitavax 200 @ 2 g/kg seed) exhibited minimum percent seed infection of Aspergillus flavus. Cloth bag was not found safe for longer storage of soybean seeds under ambient storage at Pantnagar.
