The field experiment was carried out at the Researches Station and Agricultural Experiments/College of Agriculture/Al-Muthanna University during the summer agricultural season 2020 on Okra plant. To study foliar spraying application of Proline from three levels (0, 40 and 80) mg.L −1 and gave P 0 , P 1 and P 2 respectively, Zinc sulphate (0, 20 and 40) mg.L −1 and given these Zn 0 , Zn 1 and Zn 2 . Using the randomized complete block design (R.C.B.D.) and each treatment was treated in three replicates. Means were compared using L.S.D at 0.05 level of significance. The results of the experiment showed The treatment of P 2 spraying with proline concentration (80 mg.L −1 ) was superior in the percentage of Nitrogen, phosphorus and potassium in leaves, Number of branches, Leaves area and Plant yield (g) (3.09%, 0.44%, and 2.88%, 9.04 branch plant −1 , 0.723m 2 , 303.39 g.plant −1 ) respectively. The results also showed that Zn 2 treatment was elevated (40 mg.L −1 ) on all measured indicators (3.29%, 0.37%, 2.83%, 8.76 branch plant −1 , 0.763 m 2 , 334.35 g.plant −1 ). the outperformed was in the significant effect of interaction treatment proline and zinc sulphate P 2 Zn 2 on all measured indicators.
