The study was conducted in Al-Youssoufia region which located in North West of Baghdad city during the growing season of 2018-2019. The experiment was aimed to demonstrate the optimum concentration of amino acid proline that reduce the effect of drought stress. By using three time for irrigation (4, 8, 12) day and four concentrations of proline (0, 20, 40, 60) mg. L-1 and their interaction on some growth characteristics: Root length, dry weight, nitrogen, phosphorous and potassium content, carbohydrate percentage and peroxidase activity in vegetative part. Data were statistically analysed to find out the least significant difference (LSD) between treatments at 0.05 level. The results indicated the increase of proline concentration from (0 to 60) mg.L-1 caused significant decrease in the average of growth characteristics and peroxidase activity unite.mg.proline-1 with increase in the average of irrigation periods under drought stress.
