Maize (Zea mays L.), an important crop used for animal feed and human consumption, is currently threatened by water shortage. Recently, the usage of nanomaterials has attracted worldwide attention due to their applications in various fields. This research aimed evaluate comparative efficacy different metal oxide nanoparticles mitigating drought stress maize. Iron oxide, manganese copper were biosynthesized from leaf extract Conocarpus erectus L. characterized via UV-Vis, XRD, FTIR, SEM. The synthesized initially optimized at concentrations (0, 25, 50, 75, 100 ppm). doses each nanoparticle then applied maize plants under levels (50% FC, 75% 100% FC). Compared control, application significantly improved growth parameters 30% 50% 27% 26% FC. chlorophyll content also 35%, 32%, 29% as compared respectively. antioxidants (CAT, POD, SOD, APX) 37%, 34%, 31%, Moreover, use resulted a significant decrease cellular oxidative (MDA, H2O2) 23% 50%FC, Biosynthesized FeO NPs, MnO Cu NPs have demonstrated potential maize, suggesting promising approach enhance performance water-limited conditions. Further recommended explore long-term impacts practical these findings sustainable agriculture.
