The present investigation was carried out in green house of Department of Agricultural Microbiology, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh (India) during the year 2015-16. The co-inoculation of Rhizobium + PSB at 45 DAS significantly increased no. of root nodules per plant, biomass of nodules, shoot biomass accumulation and N accumulated by shoot over control plants. Plants were allowed to grow up to 45 days under sand culture, data of plant biomass revealed that the highest dry shoot weight was (0.156 gm/plant) associated with combination of Rhz-10+PSB-142 followed by isolate Rhz-10+PSB-184 (0.137 gm/plant). Similarly, highest dry wt. of nodules was observed 1.70 mg/plant due to combinations of Rhz-10+PSB-142 followed by isolate Rhz-10+PSB-118 (1.52 mg/plant), while the highest number of nodules (6.33 per plant) associated with combination of Rhz-10+PSB-142 followed by Rhz- 10+PSB-118 (5.66 per plant). The shoot N accumulation study of the same sand culture experiment indicated that highest shoot N-uptake associated with combination of Rhz- 10+PSB-142 (4.57 mg/plant) followed by Rhz-10+PSB-184 (3.94 mg/ plant). Hence, is concluded that combination of Rhz-10+PSB-142 is the most potent N2 fixer for kulthi cultivation in acidic soils of Chhattisgarh.
