A 2-year field experiment was conducted to study the influence of three planting methods (Happy Seeder, Straw Chopper + Zero Tillage, and Conventional tillage) and four nitrogen rates (control, 75, 100, and 125% of recommended nitrogen) on the chemical and biological properties of soil. The results revealed that after soybean harvest, dehydrogenase activity and population of Bradyrhizobium sp. (LSBR 3) and plant growth promoting rhizobacteria (PGPR) were increased significantly in Happy Seeder sowing and Straw Chopper + Zero Tillage sowing than conventional sowing and population of Bradyrhizobium sp. significantly increased up to the 100% nitrogen level. There was no significant effect of different planting methods on soil chemical properties. Organic carbon and available nitrogen were increased significantly with an increase in the nitrogen level up to 100% nitrogen (N).
