Effect of Arbuscular mycorrhizal fungi (AM fungi) and Rhizobium on the nutrient uptake of pigeon pea plant.

The aim of the present study was to investigate the effect of Arbuscular mycorrhizal fungi (Glomus fasciculatum) and Rhizobium on the nutrient uptake of pigeon pea, a legume. A pot culture experiment was conducted in the Department of Life Science and Bioinformatics, Assam University, Silchar. The results showed that there was an overall increase in the nutrient (N, P, K, Fe, Cu, Zn and Mn) uptake in all the treated plants as compared to control. But dual inoculation with Glomus fasciculatum and Rhizobium had a remarkable effect on the nutrient uptake of pigeon pea plant. Cu was not detected in untreated (control) plant. But all the treated plants exhibited the uptake of copper. The combined application of microsymbionts revealed a synergistic effect in terms of nutrient uptake in legumes.
