Effect of Foliar Application For Proline, Zinc Sulphate on Growth and Yield of Okra Plant (Abelmoschus Esculentus L.)
Abstract 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 P0, P1 and P2 respectively, Zinc sulphate (0, 20 and 40) mg.L−1 and given these Zn0, Zn1 and Zn2. 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 P2 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, 0.723m2, 303.39 g.plant−1) respectively. The results also showed that Zn2 treatment was elevated (40 mg.L−1) on all measured indicators (3.29%, 0.37%, 2.83%, 8.76 branch plant−1, 0.763 m2, 334.35 g.plant−1). the outperformed was in the significant effect of interaction treatment proline and zinc sulphate P2Zn2 on all measured indicators.
