Abstract

Potential plant growth-promoting properties of Pseudomonas spp. isolated from the Rhizosphere of the Soybean plant

Wadekar SV, Kagne SR

Pseudomonas spp. has gained major attention in the agricultural industry because of its widespread application in various biotechnological processes. It is one of the rhizobacterial groups that have an important role in plant growth promoter and plant health. In the present study, Pseudomonas sp isolated from soybeans rhizosphere and identified based on biochemical reactions. Various tests were performed for the determination of the growth promoter was based on Indole Acetic acid, phosphate solubilization, and seed germination test, etc. Twenty-five isolates were identified as Pseudomonas sp that produced Indole Acetic acid, phosphate solubilization, and promote enhancement of root length, shoot length, or the number of lateral roots. Among those 25 isolates, 9 isolates showed Indole Acetic acid production and phosphate solubilization properties. Based on excellent growth promoter, 4 isolates of Pseudomonas sp were taken for final screening which was S-3, S-16, S-23, and S-24 as potential isolates of Pseudomonas sp that could be applied as inoculants of the soybean plant. The study suggested that all Pseudomonas strains enhanced plant growth in the soybean plant.
