Abstract:
Iron is an essential trace element, and its deficiency has become a major global concern affecting the health and nutrition of staple crops. In this study, iron oxide nanoparticles were biosynthesized using a green synthesis approach and characterized by UV-Vis, XRD, SEM, TEM, EDX, and FTIR analyses. The effect of foliar application of these nanoparticles on rice growth and iron accumulation in roots and shoots was evaluated. The UV-Vis spectrum showed an absorption peak at 358 nm, while XRD confirmed their crystalline nature. EDX analysis revealed a high proportion of iron and oxygen, and TEM images showed spherical nanoparticles with an average size of 6.6 nm. FTIR spectra indicated the presence of functional groups involved in nanoparticle formation. Foliar application at 100 mg/L significantly improved plant height, biomass, photosynthetic pigments, and iron content compared with controls. These findings suggest that iron oxide nanoparticles are a promising strategy for enhancing iron translocation and promoting rice growth. Their application could also be extended to other major crops such as wheat and maize to improve development and nutrient uptake.
