A pot culture experiment was conducted to investigate the effects of dual inoculation of Arbuscular mycorrhizal (AM) fungi (Glomus fasciculatum ) and Rhizobium species on the growth and nodulation of Pigeon pea ( Cajanus cajan L. ). Four treatments were conducted i.e., 1. Inoculation with Glomus fasciculatum alone. 2. Inoculation with Rhizobium alone. 3. Inoculation with Glomus fasciculatum and Rhizobium in combination. 4. Control i.e. without inoculation. The results revealed that Glomus fasciculatum markedly increased the plant growth in terms of plant height, number of leaves, plant fresh weight and dry weight. But maximum growth was observed in the plants dually inoculated with Glomus fasciculatum and Rhizobium. Higher counts of nodules were observed in the plants inoculated dually with Glomus fasciculatum and Rhizobium in comparison with the plants inoculated with Rhizobium alone.
