A pot culture laboratory experiment was conducted during 2014-15 at Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani using six different soybean cultivars to study the critical soil water potential and seed hydration value for germination of soybean varieties under different soil types. The experiment was laid out on clayey, loamy and sandy soil with six soybean cultivars as treatments and replicated thrice in randomized block design. The six soybean cultivars viz. JS-335, MAUS-71, MAUS-158, MAUS-162, MAUS-504 and MAUS-609 were used at two moisture levels at 50 per cent and 100 per cent field capacity. The results indicated that parameters like seed hydration value and seed germination rate were significantly influenced due to different soil moisture levels for different cultivars under study. Amongst six cultivars, MAUS-504 was found better for rainfed areas because of its lowest seed hydration value and was minimum critical soil moisture level for germination. The cultivars, JS-335 and MAUS-71 showed maximum seed hydration value and reduction in germination to a great extend under critical moisture level and showed optimum germination (90 to 95 per cent) under sufficient moisture level (100 per cent field capacity) condition. Under limiting moisture condition, MAUS-504 and MAUS-158 cultivars germinated well while JS-335 and MAUS-71 cultivars resulted in to poor germination.
