Effect of Spraying Iron, Zinc and Copper Nanoparticles on the Yield and Quality of Grain for Two Cultivars of Bread Wheat

This experiment was carried out in the winter season 2023-2022 and aimed to study the effect of some micro-nanomaterials in the method of leaf spraying on two cultivars of bread wheat (Al-Fayyad Genotypes V1) early growth and (Dijla Al-Khair Genotypes V2) late growth and using the Randomized complete block design in the experimental station of the Faculty of Agriculture, University of Kirkuk. With three replications, nanofertilizers were included for the micro-elements. The micro-nanomaterials (iron), (zinc) and (copper) were used separately and together with each other. The results showed that there were non-significant differences in the Grain yield with a higher average value of the Dijla Genotypes (5.68 tons.ha -1 ). As for the content of protein, wet and dry Gluten, and the percentage of extraction, of the Fayyad Genotypes was significantly higher in values (11.90%, 30.41%, 10.48%, 78.70%), respectively, compared to the lowest value of the Dijla, which was (11.57%, 28.56%, 10.00 %, 78.16%) respectively. As for the impact of fertilizer additives, the results indicated that there are significant differences between the average traits (Grain yield ton haare -1 , protein content %, wet Glutin %, dry Glutin % and extraction %), as the triple addition of the elements outperformed the other additives and gave the highest values (7.891, 12.633, 32.801, 11.49, 79.99) while the control treatments gave the lowest values.
