ABSTRACT
Climate change greatly affects different biogeochemical cycles that directly alter the normal weather pattern. This poses a serious challenge to the global community as it failed to satisfy food requirement of human and animals. With decreasing crop production and an ever-increasing population, it creates a threat to the harmony of life at multiple levels. To curb this imbalance between nutritional requirements and total population requires novel approaches in the field of agricultural science. In the need of the hour, certain stress conditions such as salinity and water stress make the situation worse for sustainable legume crop production. However, certain microorganisms inhabit the root nodules of legumes, collectively called Rhizobacteria, and have a robust mechanism to fight against abiotic stress conditions. In this chapter, efforts are made to understand certain biochemical and physiological changes that occurred in legumes under salinity and water stress conditions. Further, compilation of research efforts using microbial inoculants in legumes under said stress conditions are covered in this chapter.
