Abstract

The use of plant growth promoting rhizobacteria (PGPR) as biofertilizers is an alternative sustainable agricultural practice to improve soil health, grain quality, increase crop productivity, and conserve biodiversity. In the present study, eight PGPRs were isolated from the soybean fields of the Hadoti region, Rajasthan, out of which five were proved to be potential PGPR for various plant growth-promoting activities. The phylogenetic analysis revealed that the potentials PGPRs belong to species of Ochrobactrum sp., Achromobacter sp., were proved Alcaligenes sp., Bacillus sp., Bacillus subtilis. Seed bacterization with the isolated cultures in the current study ensures that isolated PGPRs can serve as a sustainable alternative to enrich soil quality and promote crop production. Plant growth-promoting the potential of the isolated cultures can be analyzed further for agricultural benefits on a larger scale.
