N. M. A. Fadam | R. M. Hamad
This study was carried out in the wooden canopy of the Department of Horticulture and Landscape Engineering - College of Agriculture - University of Anbar for the period from 4/8 to 11/15 of 2021 to study the effect of foliar spraying with chelated iron، the nutrient solution Prosol and the amino acid proline on some vegetative and chemical growth characteristics of pomegranate seedlings cultivar Salimi The foliar spray with chelated iron at levels 0، 30 and 60 mg. L-1 represents the first factor and is symbolized by F0, F1 and F2 sequentially, while the foliar spray with nutrient solution Prosol at levels 0, 50 and 100 mg. L-1 represents the second factor and symbolized by S0, S1 and S2 sequentially، while foliar spraying with proline at levels 0, 100 and 200 mg. L-1 represents the third factor and is symbolized by P0, P1 and P2 respectively. The results showed that the addition of chelated iron F2 led to a significant superiority in the rate of increase in plant height، number of main branches, dry weight of the root system, carbohydrates in branches and zinc content of leaves in sequence, as it reached (90.56 cm, 5.19 seedling branch-1، 88.07 gm plant-1, 12.08%, 149.84 ppm) sequentially. As for the effect of the nutrient solution Prosol, the study showed that treatment S2 was significantly superior in these traits، as it reached (80.56 cm, 5.37 seedling branch-1, 87.03 gm plant-1, 12.25%, 158.75 ppm) sequentially, as for the effect of foliar spraying with the amino acid proline The results showed that treatment P2 was significantly superior in all traits، as it reached (77.11 cm, 5.30 seedling branch-1, 86.76 gm plant-1, 12.14%, 144.43 ppm) sequentially.
