The agricultural experiment was carried out in the shadow of the Faculty of Agriculture/Basra University during the agricultural season (2020) using 5 kg plastic containers according to the complete random design and three duplicates per level with the aim of studying the impact of chloride levels in irrigation water on the vocabulary of wheat plant growth, three levels of chloride were used, the first level C1 (140) mg l-1, the second level C2 (325) mg l-1, the third level C3 (710) mg l-1. The results showed that the use of irrigation water with increasing levels of chloride led to a clear reduction in the dry weight production rate of the vegetable part of the wheat plant and an average (13.18, 12.02 and 10.81) gm pot-1, when chloride levels rise from (140) to (325 and 710) mgl-1, control to its lowest significant value of 0.91% at C3, while the percentage of magnesium increased from 0.35% for the control to 0.63% at C1, and the percentage of chloride from 0.53% for the control to 2.31% at C3. While the ratios of potassium and sodium did not show any significant differences and a decrease in the ratio of potassium to sodium, Calcium and potassium absorption decreased and chloride absorption increased significantly, while magnesium and sodium did not show any significant differences compared to the control.
