The morphometric characters and enzyme profiles of two Indigofera species were studied in the present investigation. The above parameters of the two plants were discussed under Arbuscular Mycorrhizal (AM) inoculated and uninoculated conditions. The results revealed that the phosphatases, polyphenol oxidase and antioxidant enzyme, peroxidase were higher in plants subjected to triple inoculation of both AM fungi and Plant Growth Promoting Rhizomicroorganisms (PGPRs) (Bacillus coagulans and Trichoderma viride) when compared to Glomus aggregatum and B. coagulans + T. viride inoculated plants and uninoculated (control) plants. The study also indicated that these bioinoculants could be used to improve the growth and biochemical parameters of these plants which in turn could improve the bioactive principles of these medicinally important leguminous plants.
