The effect of native dominant AM fungus Glomus aggregatum isolated from the rhizosphere soil of Indigofera aspalathoides Vahl. Ex DC and plant growth promoting rhizo-microorganisms (PGPRs) viz., Bacillus coagulans and Trichoderma viride on the growth and biochemical parameters of the medicinally important I. aspalathoides was studied in pot culture. Infection percentage and number of spores in the rhizosphere soil were higher in plants treated with triple inoculation (Glomus aggregatum + Bacillus coagulans + Trichoderma viride). Dry matter content of I. aspalathoides was high in dual inoculation (G. aggregatum + B. coagulans) whereas plant height, protein and amino acid contents were higher in triple inoculation. The macro- and micronutrients of the test plant except manganese were also higher in G. aggregatum and PGPRs treated plants than the uninoculated control. Total chlorophyll, carotenoids, lipid and phenol contents were higher in triple inoculation of I. aspalathoides than the other treatments. The inoculation of efficient AM fungus in combination with the two PGPRs had positively influenced the growth and biochemical constituents of I. aspalathoides whereas B. coagulans and T. viride as individual inoculations did not show significant effect on the test plants.
