Characterization of Root and Foliar-Applied Iron Oxide Nanoparticles (α-Fe₂O₃, γ-Fe₂O₃, Fe₃O₄, and Bulk Fe₃O₄) in Improving Maize (Zea mays L.) Performance.

ABSTRACT: Iron (Fe) oxide nanoparticles (NPs) improve crop growth. However, the comparative effect of root and foliar-applied different sources of Fe oxide NPs on plant performance at morphological and physiological levels still needs to be discovered. In this study, we characterized the growth and physiological responses of hydroponic-cultured maize seedlings to four sources of Fe (i.e., α-Fe₂O₃, γ-Fe₂O₃, Fe₃O₄ NPs, and bulk Fe₃O₄) and two application methods (root vs. foliar). Results showed that Fe concentration in root and shoot increased by elevating the level of NPs from 100 mg L^-1 to 500 mg L^-1. Overall, the responses of maize seedlings to different sources of Fe oxide NPs were as fol
