With climate change, the frequency of regions experiencing water scarcity is increasing annually, posing a significant challenge to crop yield. Barley, staple consumed and cultivated globally, particularly susceptible detrimental effects drought stress, leading reduced yield production. Water adversely affects multiple aspects barley growth, including seed germination, biomass production, shoot root characteristics, osmotic status, photosynthesis, induces oxidative resulting in considerable losses grain its components. In this context, present review aims underscore importance selecting drought-tolerant genotypes utilizing bio-inoculants constructed from beneficial microorganisms as an agroecological approach enhance growth production resilience under varying environmental conditions. Selecting with robust physiological agronomic tolerance can mitigate diverse Plant Growth Promoting Rhizobacteria (PGPR) play crucial role promoting plant through nutrient solubilization, nitrogen fixation, phytohormone exopolysaccharide secretion, enzyme activity enhancement, many other mechanisms. Applying containing PGPR, improves barley's thereby minimizing caused by scarcity.
