Abstract

This study was carried out in the greenhouse of the greenhouse plant of the Research Department of Horticulture and Garden Engineering Faculty of Agriculture / University of Kirkuk during the agricultural season 2017/2018 to study the effect of drip irrigation depth and salicylic acid spraying on the growth and yield of eggplant hybrids under protected agriculture conditions. There are three species (0, 5 and 10) and two eggplant hybrids (Kyme and Dutch) MILANO with three levels of salicylic acid (0, 50 and 100 mg). The experiment was carried out using the design of dissecting panels within the design of the complete random segments and three replicates. The differences between the averages were tested according to the Duncan Multimode Test Method. The T test was used to extract the differences between the averages at the 5% probability level. The results summarized the following: Mg. L of salicylic acid in all studied traits was plant height (82.65) cm, paper area (9.50) cm2 and the plant yield (1.43) kg, the percentage of protein (6.38)% and the percentage of carbohydrates (3.64)%. While the superiority of the hybrid (MILANO) in the form of plant height at (78.84) cm and the paper area (10.13) cm 2, the percentage of protein (6.01)% and the percentage of carbohydrates (3.50)% and the superiority of the hybrid (KYME) in the plant yield amounted to (1.57) The percentage of carbohydrates was (3.58)% and the depth of the (5) cm in the depth of the irrigation water depth (0) cm in the studied traits of the plant yield (1.77) kg and the percentage of protein was 6.05% The height of the plant was 79.85 cm and the paper area was 5.39 cm2. As for bilateral and trilateral interactions, there were significant differences as a result of these overlaps.
