A Field experiment was conducted in kharif season 2016-17 at experimental farm of Department of Soil Science and Agricultural Chemistry, College of Agriculture, Badnapur using mungbean as a test crop to studies on effect of potassium and zinc solubilizing microorganism on nutrient uptake and microbial population of mungbean. The experiment was laid out on Vertisols with five treatment combination, replicated four times in randomized block design. The treatment consists of T1 Absolute control (No fertilizer application), T2 RDF (25:50:00 N, P2O5 and K2O ha-1 kg ha-1), T3 (RDF + Rhizobium + PSB + KSB), T4 (RDF + Rhizobium + PSB + KSB + ZSB), T5 (RDF + Rhizobium + PSB + KSB + ZSB). The results emerged out clearly indicated that various microbial population like, actinomycets, fungi and bacteria was increased due to application of potassium and zinc solubilizing microorganism. It was inferred from the results that application RDF + Rhizobium + PSB + KSB + ZSB (T5) found superior over control application. The KSB and ZSB application showed synergistic effects on other nutrients (N, P, K, Zn, Fe) uptake. Soil fertility was also found to be improved due to application of potassium and zinc solubilizing microorganism to mungbean.
