Treatment of the Harmful Effect of Hydrogen Peroxide using the Amino Acid Selenocysteine and Sulfur Element on the Concentration of Nutrients in Yellow Corn Plant (Zea mays L.)

Abstract

A field experiment was conducted during the fall season (2022) in the fields of the College of Agriculture - University of Diyala in order to demonstrate the effect of the amino acid Selenocysteine and the sulfur element and the interference between them in treating the harmful effect of hydrogen peroxide and its effect on the nutrients (N, P, K, S) of the yellow corn plant (Zea mays.L). The experiment was carried out according to the randomized complete block design (RCBD), a regular factorial experiment with three replications, and the experimental parameters included the following: Three levels of spraying with acid with hydrogen peroxide (0, 5, 10) mg. liter-1 and three levels of spraying with the amino acid Selenocysteine (0, 50, 100) mg. liter-1, 2concentrations of liquid sulfur Zolfast (0, 2.5) g. Liter-1 and H2O2 was sprayed first, then the experimental factors were sprayed later, the corn crop was grown, and the results showed that spraying hydrogen peroxide with a high concentration (H10) led to a decrease in the studied characteristics, And when spraying the plant with acid (Sec), the studied characteristics increased with increasing concentrations of spray, and also these characteristics increased when spraying sulfur, and the bilateral interferences between the study factors gave a significant increase in the proportion of nutrients (N, P, K, S), and the triple interaction between The three factors of the study (H2O2 + Sec + S) treated the damage of hydrogen peroxide through the presence of an increase in the proportion of all studied characteristics when spraying the plant with amino acid and sulfur (H10, Sec100, S2.5) and when not spraying them (H10, Sec0, S0).
