This study was conducted during season of 2019/2020 at at Abu Al-Khaseeb district in Basrah/Iraq to study the effect of two amino acids proline at three concentration ( 0, 50,100) mg l-1 and cysteine at three concentration (0, 25, 50) mg l-1 and interaction between them on cabbage plants grown on saline soil at EC18.50 (dS.m-1). The results indicated that proline and cysteine significantly increased growth characteristics, physiological attributes and yields compared to the control. The interaction between proline at 100 mg l-1 and cysteine at 50 mg l-1 led to the highest levels of plant growth, yield. Proline and cystiene increased the endogenous proline and the activity of (catalase (CAT) and peroxidase (POD) enzymes ) under salinity stress.The use of amino acids such as proline at 100 mg.l-1 and cysteine at 50 mg.l-1 had an important effect on cabbage plants to mitigate the adverse effects of salinity stress.
