The present study was aimed with the formulation of suitable culture media for growth of nitrogen fixing, phosphate solubilizing and potash mobilizing bacteria in a consortium. Among different culture media, MS III media having Glucose (10 g l-1), Mannitol (10 g l- 1), Ammonium sulphate (0.5 g l-1) and Yeast extract (6 g l-1) recorded maximum growth and microbial count of Rhizobium, PSB and KMB. These three beneficial microorganisms found compatible with each other when grown on MS III culture media. Furthermore, a field experiment was conducted to study the effect of seed inoculation of consortium of Rhizobium, PSB and KMB on growth parameters and yield of chickpea. Among different inoculation treatments, seed inoculation with consortium of Rhizobium, PSB and KMB + 75% RDF was found to be the most effective as it recorded significantly highest germination (97.46%), shoot length (16.53 cm), root length (7.45 cm) and plant vigour index (2336.68) at 15 days after sowing, plant height (33.58 cm and 44.95 cm), root length (13.50 cm and 19.53 cm), dry weight of shoot (7.75 g plant-1 and 9.02 g plant-1) and dry weight of root (910.33 mg plant-1 and 968 mg plant-1) at flowering and harvest stage of the crop, number of branches (22.67 plant-1), number of nodules (24.93 plant-1), number of pods (55.47 plant-1), 1000 seed weight (127.86 g), and seed yield (20.48 q ha-1) of chickpea and found statistically indistinguishable with the treatment of seed inoculation with consortium + 100% RDF for growth parameters and seed yield of chickpea. The results indicated 25% saving of nitrogen, phosphorus and potassium dose of chemical fertilizers to chickpea. Moreover, MS III culture medium proved effective with respect to population stability of individual strain and effectiveness of consortium of Rhizobium, PSB and KMB on growth.
