Popis:	Effect of hydrogen uptake positive (Hup+) strain ofRhizobium sp. (pigeon pea) and VAM fungus (Glomus fasciculatum) was studied on the symbiotic parameters of pigeon pea (Cajanus cajan) cv. AL-15 at various levels of phosphorus. The Hup+ Rhizobium strain showed more nodulation, plant biomass and plant nitrogen content than its Hup− counterpart. VAM infection in pigeon pea roots helped in translocating phosphorus from the soil and improved nitrogen fixation. Similarly, addition of phosphorus was found to play a positive role in enhancing all these parameters. Dual inoculation of Hup+ Rhizobium strain and VAM significantly increased nodulation, nitrogenase activity, plant nitrogen and phosphorus content and plant biomass compared to single inoculation of either organism and dual inoculation with Hup− and VAM fungus.
