A master's thesis in the Department of Field Crops at the College of Agriculture at the University of Basrah discussed the effect of phosphate fertilization and iron spraying on the growth, yield and quality of oats. The student Kazem Khairallah Abdul-Zahra’s thesis included a study of the effect of four levels of phosphate fertilization (0, 50, 100 and 150 P2O5 kg H-1) and its symbol (P0, P1, P2 and P3) and four concentrations of iron spray (0, 1000, 2000 and 3000 PPM). ( and symbols for it) F0, F1, F2, and F3. The thesis aimed to study the effect of four levels of phosphate fertilization on the growth, yield and quality of oats. The thesis concluded that the fertilizer level is superior to 150 kg P2O5 H-1 in most growth, yield and quality traits. The increase of iron in the spray solution to 2000 PPM led to an increase in most growth traits and an increase in yield components. As for the interaction between the two factors, the combination F2×P3 significantly outperformed most growth traits and yield.
