Abstract

This research aimed to get bacterial isolate from rhizospheric soil of Barak Cenana, one of red rice cultivar. Rhizosphere area is a potential source as plant growth promoting rhizobacteria (PGPR) can be isolated and utilized to support growth and productivity of Barak Cenana red rice in the future. The potential of isolates as PGPR inoculants was determined based on the ability of the isolates to produce siderophores, Indole Acetic Acid (IAA), and phosphate solubilization, by in vitro screening. The results suggested that G4c isolate has potential as plant growth promoting ability, based on the promising observation of siderophores production, the highest concentration of Indole Acetic Acid (IAA) production, and phosphate solubilization. Based on 16S rRNA sequencing by using 785F and 907R primer set, G4c isolates were tentatively identified as Rhizobium pusense.
