Foliar Applications of ZnO and SiO2 Nanoparticles Mitigate Water Deficit and Enhance Potato Yield and Quality Traits

The yield and quality of field crops are affected by abiotic stresses such as water deficit, which can negatively impact crop growth, productivity, quality. However, nanotechnology holds great promise for increasing yield, maintaining quality, thus mitigating stresses. Therefore, the current study was conducted to examine influences 0, 50, 100 mg L?1 zinc oxide (ZnO) nanoparticles 25, 50 silicon dioxide (SiO2) on traits potato plants grown under deficit conditions (100%, 75%, 50% ETc). Water significantly reduced (average tuber weight, number plant tubers, yield) (tuber diameter, crude protein, mineral content). it enhanced dry specific gravity, ascorbic acid, starch, total soluble solids. Foliar applications ZnO SiO2 treatments improved plants. Moreover, significant positive correlations were found among traits. Thus, be concluded that using NPs at improves productivity negative effects in arid regions.
