Application and Perspective of Plant Growth Promoting Microbes in Development of Sustainable Agriculture

Abstract

Microbial communities in natural soil environments exhibit a cooperative link with crop productivity via. Plant Growth Promoting Microbes (PGPMs). One particular group of microbes known as Plant Growth Promoting Rhizobacteria (PGPR) is capable of alleviating the effects of biotic and abiotic stress factors either directly or indirectly. The PGPR injections have emerged as a beneficial tool for environmental sustainability as these are efficient in increasing seedling growth matrics as well as against certain plant infections that too with minimum usage of toxic pesticides. Plant Growth Promoting Bacteria (PGPB) have the ability to chelate iron, phosphate solubilization, creation of ACC deaminase enzyme under saline stress, generation of phytohormones and many others. This enormous potential makes them a truly unique microbiological candidate for bioinoculants, capable of promoting plant growth under both favourable and adverse situation.
