Study on the effect of seed moisture content, packaging materials and storage temperature on soybean seed viability, was evaluated by adjusting 2 levels of seed moisture content at 6 and 9 %. Five packaging materials: tin can, plastic bag, plastic vacuum and aluminium foil compared with cloth bag, stored at room temperature (30-32 deg Celsius) and low temperature (15 deg Celsius). Seed samples were drawn monthly for determining seed viability (seed germination), seed moisture content, speed of germination and electrical conductivity. The seed viability of two levels seed moisture contents at low temperature storage was lower than room temperature. At high seed moisture contents, stored in aluminium foil and plastic vacuum, the seed quality would decline after 3-4 months of storage periods at room temperature condition. Seed vigor evaluated by speed of germination and E.C. value. Higher seed moisture content, room temperature storage showed rapidly decreased seed vigor, E.C. value after 3 months of storage duration. Aluminium foil containers however, were suitable for delaying seed deterioration at room temperature storage. On the contrary, at low seed moisture content tin can and aluminium foil containers at low temperature were ideal for controlling the seed deterioration
