Abstract: The present investigation was conducted in glass house of Department of Agricultural Microbiology, College of Agriculture, IGKV, Raipur, Chhattisgarh during Rabi season, 2016-17 comprising 9 treatments (treatments were different bacterial consortia and control without inoculate in bacteria and 3 replications in CRD with the objective to find out the effect of non rhizobial nitrogen fixer of bacterial consortia on rhizobium nodulation behaviour in chickpea. The results of nodule study under pot experiment revealed that the highest nodulation was recorded in with T5: chickpea with rhizobium +75%NPK i.e. 39.33 followed 38 plant-1 by T3: (Chickpea +consortia of Rhizobium, Azotobacter, Azospirillum +75%NPK) and least plant nodule was recorded as uninoculated of control with 12.33 plant-1 at 45 DAS. The highest fresh nodule weight was T5 (48.33 mg plant-1) followed by T3 (45 mg plant-1) and fresh weight of control was (18.33 mg plant-1). Dry weight in T5 (22.67 mg plant-1) followed by T3 (19.33 mg plant-1) and dry weight of control was 6.33 (mg plant-1). Further C1 also has maximum root length (27.00 cm) and root biomass (7.30g) as compared to other treatments. Overall results revealed that there is no significant reduction in nodulation by the presence of other non symbiotic nitrogen fixer. However, other plant growth was positively in presence of symbiotic and non symbiotic members in same microbial consortia.
