The Interaction between Adding Soybean Residue and Hydrogel to the Soil on the Mineral Content of Yellow Corn (Zea mays L.) Plants whose Seeds are Treated with Ascorbic Acid

Abstract

This study was conducted in the warehouse of the Department of Biology / College of Education for Pure Sciences for the 2023-2024 season to study the effect of adding levels of hydrogel (0, 2, 4) gm/kg of soil and residues of the vegetative part of soybeans at levels (0, 4, 8) gm/kg soil in the mineral content of yellow corn plants soaked with concentrations of (0,100, 200 ppm) of ascorbic acid. The results were analyzed using a completely randomized design and a factorial experiment with three replications. The results confirmed the existence of a discrepancy in the effect of soybean residues on mineral elements, as they ranged between inhibition and stimulation, as the residues had a stimulating effect on the calcium and nitrogen elements, While its effect was inhibitory to the element sodium and magnesium, and the addition of hydrogel showed a stimulating effect in all the nutritional elements mentioned above. On the other hand, there was a significant superiority in the content of the elements with an increase in the concentration of ascorbic acid compared to the control treatment without addition. The interactions showed a stimulating effect, especially the interaction of hydrogel levels with ascorbic acid concentrations in the studied characteristics
