Arbuscular mycorrhizal fungal (AMF) interaction with other microorganisms on the Withania somnifera (L.) Dunal, was carried out under the greenhouse condition and their beneficial impacts were discussed. There is a contradictory statement of mycorrhizal colonization in solanaceae; therefore an attempt was made to explore mycorrhizal association with AM fungus (Glomus macrocarpum), Azotobacter and Phosphate solubilizing bacteria (PSB). Green house experiments on Withania somnifera was carried out with following treatments (1) control (non-inoculated) (2) Glomus macrocarpum (3) Glomus macrocarpum+ Azotobacter (4) Glomus macrocarpum + PSB (Bacillus subtilis) (5) Glomus macrocarpum + Azotobacter + PSBin which triple inoculation (Glomus macrocarpum + Azotobacter + PSB) shows higher shoot, root length and dry weight of shoot and root followed by dual and single inoculation compared to non-inoculated plants. The experimental plants revealed higher in per cent of root colonization, spore number and P uptake of shoot, after triple inoculation compared to control plants.  The result suggests that there is a synergistic interaction with different bio-inoculants and the increase of biomass with the application of these bio-inoculants.

Keywords: Solanaceae, Withania somnifera, bio-inoculants, Glomus macrocarpum, Azotobacter, Phosphate solubilizing bacteria (PSB), Bacillus subtilis.
