Drought stress limits wheat ( Triticum aestivum L.) productivity by disrupting plant growth, photosynthesis, and other metabolic activities. During recent times, the use of micronutrient-based nanoparticles (NPs) has emerged as a potential strategy to mitigate drought stress. However, comprehensive studies comparing their individual and combined effects on wheat under varying drought conditions are limited. This knowledge gap includes the lack of physiological and biochemical assessments of the integrated use of different NPs as well as insufficient understanding of their role in regulating oxidative stress and improving grain yield and quality of wheat under drought conditions. This study investigated the ameliorative role of different nanoparticles (NPs), namely iron (Fe), zinc (Zn), and silicon (Si), on wheat under different levels of drought stress. A pot experiment was conducted to assess the impact of these NPs on plant growth, indicators of oxidative stress, activities of antioxidant enzymes, and yield attributes of wheat. Present results revealed a significant reduction in growth, biomass accumulation, and yield attributes under drought stress. On the other hand, the use of NPs led to a marked improvement in morpho-physiological growth, biomass, and yield, suggesting their potential to alleviate the negative impacts of drought on wheat. Among the treatments, the combined use of Fe and Zn-NPs (T 5 ) showed most promising results for wheat growth under drought stress, w...
