Abstract: The Physiological changes such as speed of germination; seedling dry weight and moisture content are occurred in seeds during storage. Literature reported that these changes mainly depend upon the type of storage containers, variety of the seeds used and storage conditions. In the present study three different bags Polythene bag (C1), Cloth bag (C2) and Jute bag (C3) of dimensions 20 cm x 30 cm were used for the storage of soybean seed of four different varieties JS-335 (V1), AMS-99-33 (V2), TAMS-38 (V3) and TAMS-98-21 (V4) under ambient temperature and relative humidity for a period of 18 months. The seeds from each container were removed after 3 months (90 days) and examined for different physiological observations. Maximum speed of germination (20.33) was observed in JS-335 variety, followed by AMS-99-33, TAMS-38 and TAMS-98-21 as 18.67, 14.67 and 13.67 respectively at the end of 540 days of storage. Among the storage containers the seeds stored in Polyethylene bag recorded the highest value of speed of germination followed by Cloth bag at the end of storage and seeds stored in Jute bag recorded lowest value of speed of germination in the variety TAMS-98-21. Thus, JS-335 variety showed least effect on speed of germination during storage as compared to AMS-99-33, TAMS-38 and TAMS-98-21. Maximum seedling dry weight (0.98 gm) was observed in JS-335 variety, followed by AMS-99-33, TAMS-38 and TAMS-98-21 as 0.91 gm, 0.81 gm and 0.74 gm respectively at the end of 540 days of storage. The corresponding moisture content values of soybean varieties JS-335, AMS-99-33, TAMS-38 and TAMS-98-21 when stored in Polyethylene, Cloth and Jute bags were different. Variety JS-335 seeds recorded lower moisture content (9.1 %) as compared to AMS-99-33, TAMS-38 and TAMS-98-21.
