Biogenic synthesis of iron oxide nanoparticles using Moringa oleifera and chitosan and its evaluation on corn germination

Abstract:

To stimulate sustainable nanotechnology in agriculture, we have developed an easy, low-cost, and eco-friendly method for the synthesis of iron oxide nanoparticles (MHCFe) using Moringa oleifera leaves and chitosan. The effect of these iron oxide nanoparticles on corn seeds germination was evaluated. The biogenic synthesis was performed by using a one-pot chitosan-moringa hydrothermal treatment. Structural characterization was carried out by Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Magnetic properties were evaluated using a vibrating sample magnetometer (VSM). The synthesized iron oxide nanoparticles loaded with nitrogen, phosphorus, and potassium (NPK) were used to study the germination rate and early growth of corn seed. The combination of moringa and chitosan has a positive effect on the Index-speed germination and growth parameters of corn plants and no toxic impact on seed germination.
