Abstract

Bio-inoculant (Consortium of Rhizospheric Microorganisms) serves as an energy source for improving the growth and productivity of various agricultural crops in dry areas. Because Bhokar is located in a hilly area, the soil lacks the necessary microbiota for phosphate solubilization, symbiotic or asymbiotic nitrogen fixation, manufacture of plant growth hormones, siderophore, and other biogeochemical processes. As a result of the overuse of pesticides in agriculture, the remaining microflora population is reduced. The presence of Rhizospheric microbiome from the Bhokar agricultural area has been discovered in the current experiment. Three separate agricultural soil samples (Sample A, B, and C) were collected and examined at the VNMK University's Soil Testing Department in Parbhani, MS, India. The pH of Samples A and B is somewhat alkaline, at 8.08 and 8.33, respectively. Sample A had a high concentration of organic carbon at 1.0 percent, while sample B had an average organic carbon concentration of 0.58 percent. Electric conductivity, CaCO3 concentration, nitrogen, phosphorus, potassium, copper, iron, magnesium, and zinc concentrations were all measured in both samples. From the soil samples collected, 43 morphologically distinct species were isolated. Phosphate Solubilizing Microorganisms (PSM), Rhizobium sp., Pseudomonas sp., Azotobacter sp., Trichoderma sp., Aspergillus sp., and Penicillium sp. were isolated using selective media. In the Bhokar agricultural areas, all of these isolated microorganisms will play an important role in improving growth, crop productivity, and controlling plant diseases.

Keywords:Bio-inoculant, Rhizospheric microorganisms, biochemical study, soil samples, PSM.
