Sustainable increase in agricultural production while keeping the environmental quality, agro-ecosystem function and biodiversity is a real challenge in current agricultural practices. Application of PGPR can help in meeting the expected demand for increasing agricultural productivity to feed the world's booming population. Global concern over the demerits of chemicals in agriculture has diverted the attention of researchers towards sustainable agriculture by utilizing the potential of Plant Growth Promoting Rhizobacteria (PGPR). Use of PGPR as biofertilizers, biopesticides, soil, and plant health managers has gained considerable agricultural and commercial significance. 

The bookPlant Growth Promoting Rhizobacteria (PGPR): Prospects for Sustainable Agriculturehas contributions in the form of book chapter from 25 eminent global researchers, that discusses about the PGPRs and their role in growth promotion of various crop plants, suppression of wide range of phytopathogens, their formulation, effect of various factors on growth and performance of PGPR, assessment of diversity of PGPR through microsatellites and role of PGPR in mitigating biotic and abiotic stress.This book will be helpful for students, teachers, researchers, and entrepreneurs involved in PGPR and allied fields. The book will be highly useful to researchers, teachers, students, entrepreneurs, and policymakers.
