Abstract
The experiment was conducted during the fall season of the 2023-2024 agricultural season in the tomato cultivation project using modern technologies affiliated to the Basrah Agriculture Directorate in Khor Al-Zubair. With the aim of studying the effect of foliar spraying with proline acid and chelated iron at three concentrations of each (0, 100, 200) mg L-1 and the interaction between them on the growth and yield of potato plants of the Prowin variety. The results showed a significant superiority of spraying with proline acid at a concentration of 200 mg L-1 in plant height, number of aerial stems, number of leaves, leaf area, number of tubers, marketable yield, total yield, percentage of dry matter, starch and specific gravity of tubers. Plants sprayed with chelated iron at a concentration of 200 ml L-1 gave a significant superiority in number of aerial stems, number of leaves, leaf area, marketable yield and total yield. The interaction between the two study factors showed a significant effect on all studied traits except for the percentage of total soluble solids. Plants sprayed with proline acid and chelated iron at a concentration of 200 ml L-1 each gave the best values for marketable yield and the total yield reached (22.25, 24.75) tons/ha with an increase rate of (91.15, 92.29) % compared to unsprayed plants, respectively.
