Abstract

The inoculation of legumes with Rhizobium (Bradyrhizobium) strains selected for high nitrogen fixation under stress conditions of temperature, moisture, and other abiotic and biotic conditions including antibiotics particularly. A research trial was conducted on Effect of Rhizobium strains on the growth stages and yield of pigeonpea in Vertisol at the Department of Soil Science, JNKVV, Jabalpur (M.P.) There were twelve treatments (6 exotic, 2 local strain, FUI, UFUI and two Maize control) with four replication laid out in randomized block design. The result shown that Rhizobium strain R1 (BRP20) performed best in pigeonpea at different growth stages (25, 45, 65 and 85 DAS) for nodulation attributes (nodule enumeration, its biomass and leg hemoglobin content) by 72.00, 75.00, 60.00 and 34.00%; 63.50, 19.00, 10.30 and 9.70%; and 60.00, 69.00, 72.00 and 69.00% over that of fertilized un inoculated (FUI); plant growth attributes (plant height ) by 69.30, 20.90, 22.45 and 24.10%; over that
