Microwave Synthesis of Fe2 O3 and ZnO Nanoparticles and Evaluation Its Application on Grain Iron and Zinc Concentrations of Wheat (Triticum aestivum L.) and their Relationships to Grain Yield

Fe2O3 and ZnO nanoparticles were synthesized by a fast microwave method. Nanostructures were characterized by X-ray diffraction  and scanning electron microscopy. The goal of bio-fortification is to develop plants that have an increased content of bioavailable nutrients in their edible parts. The micronutrients magnesium (Mg), manganese (Mn) and copper (Cu), boron (B) and calcium (Ca) are essential for plants and the humans and animals that consume plants. Increasing the micronutrient density of staple crops, will greatly improve human nutrition on a global scale. In order to investigate the effect of Iron and Zinc on nutrient uptake of two line of wheat. The experimental design used for this research was a factorial experiment under complete randomized block design with three replications and two variety of wheat including Roshan back cross (V1) and C-78-14 line (V2), three levels of Iron from Fe-EDDHA (Sequestrene138) including no application (F0), Fe sulphate (F1) and Nano Fe2O3 (F2) and three Levels of  Zinc as zinc sulphate (ZnSO4) including no application (Z0), 25 kg/ha-1 (Z1) and 50 kg/ha-1 (Z2) were used. The result is showed that application of nanoparticles increased the study of parameters such as magnesium, manganese, copper, boron and calcium. Highest levels of grain yield with 5.13 ton/ha-1 was obtained in C-78-14 variety.
