Abstract: The application of organic treatments has a favorable impact on the rhizosphere soil microbial population and on soil physico chemical properties. The present investigation was carried out at North-Eastern Hill University, Department of Botany to study the effect of different organic treatments combinations (soil+vermicompost, plant compost+vermicompost+soil in different ratio) on potato plant. Potato was planted in the pots with different types of treatment combinations in different ratios plant+soil compost (1:2) showed the highest fungal population and soil+vermicompost (1:2) recorded the highest bacterial population. A significant variation in bacterial population was observed according to Tukey’s test at p = 0.005. Application of different organic treatment combinations favorably influenced the physicochemical properties of soil and exhibited a significant variation among various combination ratio according to Tukey’s test at p = 0.005. Organic carbon and available phosphorus was found to be highest in soil+plant compost+vermicompost at1:2:1 ratio. The study indicated that the application of organic amendment at different combinations favorably influence the microbial population and physicochemical properties of rhizosphere compared to soil where no organic amendments were applied.
