dc.description.abstractField evaluation of microbial consortia developed in the Department of Agricultural Microbiology, College of Agriculture, University of Agricultural Sciences, Dharwad was done in green gram crop in field of MULLaRP scheme during kharif 2017. The microbial consortia included Gluconoacetobacter sp., Azospirillum sp. (ACD 15), P-solubilizing bacteria (Pseudomonas striata), K-solubilizing bacteria (KSB-27), Zn-solubilizing bacteria (ZnSB), plant growth promoting rhizobacteria (JK-16), pink pigmented facultative methylotrophs (PPFM-33 and PPFM-58), lactic acid bacteria (LAB 82, LAB-75 and LAB LS-36), Si-solubilizing bacteria (SiSB) and actinomycetes strains (AUDT-502, AUDT-248, A-34, PSA-5, PSA-7 and UPM-34) with 100 per cent and 75 per cent recommended dose of fertilizers. The consortia were inoculated to green gram by seed treatment (4 ml kg-1 seed), soil application (2.5 l acre-1 with 250 kg vermicompost) and as foliar spray (4 %). The consortia inoculated treatment along with 50 per cent recommended fertilizer dose showed significantly highest plant height (63.75 cm plant-1), number of leaves (32.67 plant-1), nodulation (58.49) and nodules dry weight (1.17 g plant-1) and also highest nutrient content and its uptake as compared to uninoculated control (Package of practices only). The treatment with 50 per cent NPS along with microbial consortia recorded highest number of pods (29.75 plant-1), total dry matter (15.84 g plant-1) and grain yield (16.68 q ha-1) as compared to full dose of recommended chemical fertilizers and also higher B: C ratio (3.28) was noticed in this treatment. The present investigation has come out with the result that inoculation of selected microbial consortia enhanced the growth, yield, soil health and nutrient uptake by green gram. I recommend application of rhizosphere consortia-2 (Gluconoacetobacter sp., Pseudomonas striata), KSB-27, ZnSB, plant growth promoting rhizobacteria (JK-16), PPFM-33 and LAB-75) which could reduce 50 per cent of recommended NPS (nitrogen, phosphorous and sulphur) fertilizers thereby reducing input cost on chemical fertilizers.
