The sustainability of life on the earth is dependent on the soil characteristics because of soil has crucial role in agriculture so the dynamic nature of soil is a directly affected by soil microbes, In the current scenario increasing population in the world needs high agricultural yield so to fulfill the demand leading to production and utilization of chemical fertilizers and pesticides in the agricultural field but that caused the degradation of soil quality and remove soil fertility so current agricultural researcher are turn their attention to a safer and productive means of agricultural practice such as the use of plant growth promoter rhizobacteria for improving agricultural productivity to address population demand with environmental ecofriendly, plant growth promoter are improve agricultural productivity by direct and indirect mechanism for sustainable agriculture, in this review paper tray to review the mechanism that plant growth promoter rhizobacteria are use to enhance plant growth specifically bacterial trait that are use for increasing crop productivity, worlds current progress in utilization of plant growth promoter rhizobacteria for various application and the integration of biotechnology tool like metagenomics research and nanotechnology current and feature prospect for identification and utilization of such beneficial soil bacteria for agricultural sustainability are fully reviewed so this paper are used as information giver about new technology in agriculture .
