Abstract: In the current farming practices, the use of PGPR as an alternative is likely to increase the soil fertility and produce better crop yield than the conventional mode of farming. This type of agriculture uses special farming techniques. Sustainable agriculture is vital in today’s world as it offers the potential to meet our agricultural needs. In the present farming practice, PGPR and environmental resources can be fully utilized. The alternative scientific technologies are productive, economic, resource serving and appropriate to many farming situations all over India. Thus the technique is ecofriendly and ensures safe and healthy agricultural products. Microbial populations are instrumental to fundamental processes that drive stability and productivity of agro-ecosystems.

Keywords: PGPR, Sustainable agriculture, Conventional method, Biological farming, Mineralization
