Due to extended periods of below-normal rainfall and rising temperatures, drought is a significant global issue for agricultural productivity. Hydrological, agricultural, meteorological droughts all pose different problems with regard the availability water important crops, which in turn impacts plant development yield. Depending on crop species stage maturity, stress degrades metabolism physiological processes, resulting decreased growth yield losses that can range from 30% 90%. Acclimatization adaptation are two basic techniques plants use survive drought. Rapid alterations processes chemical composition, including modifications osmotic pressure, root leaf size, antioxidant systems, part acclimatization. Xerophytism succulence characteristics drought-resistant have evolved assist preserve cellular integrity balance water-limited environments. Even these tactics, majority crops—such as maize, rice, wheat—remain extremely vulnerable stress. To lessen effects drought, researchers looked into number strategies, both conventional cutting-edge methods. Conventional techniques, like application growth-promoting bacteria (PGPB) morphological modifications, remain essential improving resilience. Recent breakthroughs provided innovative alternatives such nanoparticle (NP) treatments biochar, enhance Biochar enhances soil moisture retention nutrient accessibility, whereas nanoparticles augment absorption bolster molecular resilience under Furthermore, microbial inoculants absorption, facilitating arid conditions.
