A laboratory experiment was conducted during 2014-15 at Department of Soil science and Agricultural Chemistry, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani using different six soybean cultivars to study the water diffusivity value for germination of soybean varieties under different soil types. The pot culture experiment was laid out on clayey, loamy and sandy soil with six soybean cultivars as treatments 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 germination percentage, seed hydration value and seed germination rate were significantly influenced due to different soil moisture levels for different cultivars under study. Amongst six cultivars, JS-335 showed lowest germination percentage while MAUS-162, MAUS-504 and MAUS-609 showed maximum germination percentage in all three soil types. Amongst the clay, loam and sandy soils loam soil found better in supplying the soil moisture for seed germination.
