Cereal crops are essential for providing nutrients and energy in the daily human diet. Additionally, they have a crucial role as significant constituent of cattle feed, hence enhancing meat production. Drought, being an abiotic stressor, adversely affects growth yield numerous on global scale. This issue poses pressing obstacle to maintaining cereal crop production ensuring food security. Nanoparticles become valuable resource improving productivity under ongoing rapid climate change escalating drought conditions. Among these, silica nanoparticles (SiNPs) demonstrated their potential agricultural applications regions with limited water availability. Drought stress has detrimental effects crops, impacting growth, metabolic, physiological processes, hampering nutrient absorption, disrupting cellular membranes, damaging photosynthetic apparatus, reducing antioxidant activities by altering gene expression. SiNPs help preserve regulate balance, improve resulting substantial enhancement plant water-deficit also protect system enhance its efficiency, facilitate accumulation phenolics, hormones, osmolytes, activities, expression, thus empowering plants increased resistance stress. Moreover, decrease leaf loss promoting stomatal closure, primarily fostering abscisic acid (ABA) mitigating oxidative damage activating defence reactive oxygen species (ROS). However, number studies examine In this review, we highlighted promising resilience changing morpho-histological traits, properties, expression maintain security drought-prone areas. study will aid researchers using environmentally benign way order fulfill supply needs.
