Abstract: A field experiment was conducted with Phaseolus vulgais L. plants inoculated with one of the four AM-fungal strains viz. Gigaspora albida, Glomus albidum, Sclerocystis sinuosa and Scutellospora erythropa plus Rhizobium and / or one-half dose of phosphatic fertilizer. The root, shoot and leaves of plants were assayed for amino acid, protein, phenol and neutral lipid contents at 45 days after sowing (DAS) and 75 DAS. Comparative assessment revealed that amino acid, protein and phenol contents were maximum in the leaves of dual inoculated plants whereas neutral lipid concentration was maximum in the leaves of plants treated with AM-fungi plus one-half dose of chemical phosphorus at 75 DAS. Results also revealed that the neutral lipids and proteins were found to be higher in different plant parts whereas amino acids and phenols were comparatively lesser. However, when compared with un-inoculated plants, AMF inoculated contained more amino acid, protein, phenol and neutral lipids. Protein, neutral lipid and phenol contents in the leaves were 12-13% more than the non-mycorrhizal plants, whereas amino acid was 18-19 % more than the plants treated with full dose of phosphatic fertilizer as well as untreated control plants.
