Wheat is the most important food on earth. Therefore, to produce high quality products with efficient utilization, the micronutrient groups are needed. This investigation was conducted to determine the effects of soil and foliar application of Fe, Zn, and Cu on the quantity and quality characteristics and nutrients accumulation in wheat. Experimental treatments were made to a control, Fe, Zn, Cu, FeZn, FeCu, ZnCu, FeZnCu in two groups (soil application and foliar application), carried out as a completely randomized block design in four replications at Arak University in Iran. Amounts of soil application of those elements were: 5 kg.h-1 Sequstrine 138 Fe, 20 kg.h-1 ZnSo4, and 10 kg.h-1 CuSo4. Foliar application was the concentration of 2 per thousand in stages of tilling and stem elongation. According to the results, grain yield, dry matter, the concentration of Fe, Zn and Cu, protein percent, wet gluten, gluten index, bread volume, hardness index and water absorbtion traits were significant (P<0.01). Our researchers ensured that treatments showed higher groups compared to the control of Fe, FeZn in the soil application (14.57 and 12.23%, respectively) and FeZnCu in the foliar application (7.82%) for grain yield and treatments of Fe, FeZn in soil application (16.28 and 13.99%, respectively), and FeZnCu in the foliar application (9.67%) for dry matter. The soil application of Cu had the highest effect on protein percentage (15.43%), wet gluten (43.24%), bread volume (556.09%), hardness index (51.01%), and water absorbtions (68.02) of wheat. The highest coefficient of variation belonged to wet gluten and gluten index, which would be employed in the wheat bread breeding program to improve the baking quality characteristics in breeding materials.
