In the present study we investigated antimicrobial activity of diethyl ether and methanol extractions of bark and leaves of Ficus religiosa plant against three bacteria (E.coli, Staphylococcus aureus and Pseudomonas aurignosa) and one fungi (Aspergillus niger). The results showed that the methanol extracts of both leaves and bark showed antimicrobial activity on three tested bacteria and no effect on A.niger. In methanol extracts S.aureus showed maximum sensitivity (inhibition zone 28mm) followed by E.coli (inhibition zone 16mm) and Pseudomonas aeruginosa (inhibition zone 12mm). Diethyl ether extracts of leaves were also showed maximum inhibition on S.aureus followed by E.coli and P.aeruginosa. Both methanol and diethyl ether extracts of bark showed antimicrobial activity on three types of tested bacteria and very less inhibition activity on A.niger. But comparatively bark extracts of both the solvents were showed less antimicrobial activity than leaves extracts on the tested microbes.

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.
