Developing plant growth promoting rhizobacteria as bio-inoculants to enhance crop yield under stress condition

Abstract

Stresses are the prime factor for limiting agricultural productivity, during growth and development process plants inevitably experience a variety of abiotic stresses, such as drought, salt, and extreme temperature in which drought is most devastating abiotic stress. Recently searching for plant growth promoting rhizobacteria (PGPR) for sustainable crop production and proven to be an good alternative to chemical and to control abiotic stresses. The technique of growth promotion by PGPR that may be either direct or indirect effect on the plant productivity. Plants-microbe interaction is essential for the ecosystem. when stress level increases in environment, it becomes more essential to characterize and decipher plant–microbe association in relation to defense against environmental challenges. By isolating, characterizing and inoculating with effective bio-inoculants of rhizobium and Pseudomonas fluorescens can reduce abiotic stress in my crops and gives higher yield. Bio-inoculants help to cope up with adverse environment condition and providing stress free condition resultant increase the production and productivity of crop.
