Soil microbiology is a millennium dollar important field in the agriculture sector in terms of growth, development, and high yield. Earlier efforts were in the direction of use of chemical fertilizers to get fast and quick results. But during the last decades, some harmful effects of these seem to be showing discouraging results for rhizospheric microflora. Plant growth-promoting rhizobacterial world is an amazing and magical invisible world with promising results. Commonly available PGPR genera include bacterial strains such as Agrobacterium, Arthrobacter, Azotobacter, Azospirillum, Bacillus, Caulobacter, Chromobacterium, Flavobacterium, Micrococcus, Pseudomonas, etc. If their colonization is encouraged by creating favorable conditions for their growth, then the cost of an external phytohormone, growth enhancers, and nitrogen fixers can be minimized. This review focuses on some of the significant characteristics of direct mechanism of action of PGPR which should be focused more and should be implemented successfully under various agricultural lands where cultivation practices are literally difficult.
