IMPACT OF THE SEED TREATMENT , PACKING MATERIALS AND STORAGE TEMPERATURE ON VIABILITY OF SOYBEAN

An attempt was made to know the effect of different treatments on seed viability. Experiment was conducted by using three factors like seed treatment with fungicides, storage containers and storage conditions. Among the fungicide treatment the maximum germination (88.94 %), root length (16.07 cm), shoot length (19.83 cm) and seedling dry weight (1.69 g) was observed in X2 seeds compared to X1 and X0. Among the packing materials the significantly maximum germination (93.72%), root length (18.29 cm), shoot length (18.59 cm) and seedling dry weight (1.76 g) was observed in vacuum packed seeds (C3) followed by polythene bag (C2), gunny bag (C4) and cloth bag (C1). As per the storage conditions the cold storage (A2) showed maximum germination (90.86%), root length (17.60 cm), shoot length (22.42 cm) and seedling dry weight (1.73 g) compared to the ambient storage (A1). The interaction effects between all twenty four treatments, X2C3A2 showed maximum germination (97.96%), root length (24.20 cm), shoot length (30.57 cm) and seedling dry weight (2.05 g) after two months of storage. Among the fungicide treatment X2, among the packing materials vacuum packing (C3), among the storage condition cold storage (A2) and among the interaction X2C3A2 showed significantly maximum germination, root length, shoot length and seedling dry weight throughout the storage period.
