In the present study 6 strains of pseudomonas, 4 strains of Azotobacter and 2 strain of Bacillus were isolated from Rice rhizospheric soil samples from different villages of Bardoli, Gujarat, India. Primary screenings were carried for their plant growth promoting activities such as IAA production, Phosphate solubilization, siderophore production, N2 fixation and protease production. The consolidated positive results of PGPR activities were revealed most potential 15 isolates for other PGPR activities such as cellulase production, chitinase production, HCN production and antifungal activity. Overall investigation of the rhizospheric diversity of the rice field of Bardoli region revealed many potential PGPR candidates with significant results which can be utilized as potential biofertilizer for improving soil health and rejuvenization. Looking to overall PGPR activities together, isolate, M2 was found most efficient for all the activities under study.

Key words: Rhizobacteria, PGPR, Biocontrol, Plant growth promoting activities, Biofertilizers
