Abstract
Abiotic stresses especially drought affect agriculture lands; thereby they impinge on plant growth and cause in reduction in crop productivity and quality. As reported, drought stress contributes a chief proportion in demolition of cultivated land area and further crop productivity. Plant growth-promoting rhizobacteria (PGPR), a biological agent in agriculture that helps to lessen drought stress, has been considered the most promising approach to enhance production and yield in drought-affected regions. Hence, to mitigate drought stress, adopting an eco-friendly approach to meet future needs is the best way to go in. The present chapter deals with role of important benign microbes and their elicitors in alleviation of drought stress and promotes plant growth promotion.
