A field experiment on “Effect of microbial consortia on growth, nodulation, yield and nutrient uptake of soybean” was carried out during Kharif 2018-19 under the Department of Soil Science & Agricultural Chemistry.The experiment was laid out under randomized block design (RBD) with 3 replications and 9 treatments comprising beneficial microorganisms of Actinomycetes, Arthrobacter and PGPR (P. fluorescens) in possible combinations applied as seed treatments and additionally P.fluorescens was applied as foliar application at 20, 40 and 60 DAS of the crop growth stages. The crop was supplemented with recommended dose of fertilizers 20:80:20 (N: P2O5: K2O kg ha-1) at basal application. Besides these, two types of control plots were maintined as fertilized uninoculated control (FUI) and unfertilized uninoculated control (UFUI). Results revealed that the significant improvement were noticed in plant growth attributes of nodulation (57 and 43.5%), over control (9.5 and 33.4 nodule plant-1) and its biomass, (71 and 43%),over the control (0.38and 1.12 g plant-1) plant height 47, 38, 32% over the control (16.3, 35 and 45.4 cm) and its biomass, (39, 57 and 65%), over the control 1.22, 3.41and 6.07 g plant-1 leaf chlorophyll content (32 and 31.0 %) over the control (2.65 and 2.92 mg g-1leaf) all at 25, 45 and 65 DAS, nutrient contents (N, P and K seed and stover respectively) 58 and 122%, 65 and 101%, 70 and 86% over the control 98.5, 63.8, 5.2, 7.4, 24.9 and 44.4kg ha-1, yields 44 and 61% over the control 1636 and 3345 kg ha-1 respectively (seed and stover) at harvest of the crop.
