The pot culture experiment was carried out to evaluate the influence of different combinations of microbial inoculants
(VAM+AZO+PSB) on soil phosphatase activity and nutrients (N, P, K, Cu, Zn, Fe, Cu & Mn) of Stevia rebaudia plant
rhizosphere on 20th, 40th and 60th day. The study revealed that the combined application of microbial inoculants on soil Alkaline
and Acid phosphatase activity has been found maximum at 60th day in triple inoculated plants than dual inoculated and control.
The results also showed that the soil macronutrients (N, P & K) and micronutrients (Zn, Fe, Cu & Mn) have been found to be
maximum at 40th day and 60th day respectively in triple inoculated plants than dual inoculated and control. The high alkaline
and acid phosphatase activity in triple and dual inoculated soils attributes to the production of more enzymes by the synergetic
interaction of VAM fungi, Azotobacter sp. and Phosphate solubilizing bacteria. This leads to the high yielding in the grown plants.
