ABSTRACT

The pot culture experiment was carried out to evaluate the influence of different combinations of microbial inoculants (VAM + AZO + PSB) on soil phosphatase activity andnutrients (N, P, K, Cu, Zn, Fe, Cu & Mn) of Steviarebaudia plant rhizosphere on 20th, 40th and 60th day. The study revealed that the combined application of microbial inoculants onsoil 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.
