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.
