Plant Growth Promoting Rhizobacteria (PGPR) as Green Bioinoculants: Recent Developments, Constraints, and Prospects

The quest for enhancing agricultural yields due to increased pressure on food production has inevitably led the indiscriminate use of chemical fertilizers and other agrochemicals. Biofertilizers are emerging as a suitable alternative counteract adverse environmental impacts exerted by synthetic facilitate overall growth yield crops in an eco-friendly manner. They contain living or dormant microbes, which applied soil used treating crop seeds. One foremost candidates this respect is rhizobacteria. Plant promoting rhizobacteria (PGPR) important cluster beneficial, root-colonizing bacteria thriving plant rhizosphere bulk soil. exhibit synergistic antagonistic interactions with microbiota engage array activities ecological significance. promote facilitating biotic abiotic stress tolerance support nutrition host plants. Due their active endorsing activities, PGPRs considered hazardous fertilizers. biofertilizers biological approach toward sustainable intensification agriculture. However, application increasing several pros cons. Application potential that perform well laboratory greenhouse conditions often fails deliver expected effects development field settings. Here we review different types PGPR-based biofertilizers, discuss challenges faced widespread adoption deliberate prospects using
