The presented study was carried out in private field, in Al Hashimiyah, Babylon province, during 2020 autumn season to study the effect of anatomical, chemical and phenotypic variation of eggplant (cv. Barcelona) under different levels of salty irrigation water and stimulate plant productivity by spraying α-Tocopherol and their interaction on studied indicators. Experiment was included two main factors, the first factor was three levels of salty irrigation water (1.5, 3 and 4.5 ds.m-1) and the second factor was spraying eggplant with three concentrations of α-Tocopherol (0, 75 and 150 mg.L-1). Three sprayings were applied during the season and time between each spraying was two weeks. Results showed that there were significant effect of the two studied factors on the phenotypic traits as the 1.5 ds.m-1 level of salty irrigation water was significantly increased (plant height, leaf area, the number of branches, dry weight of total vegetative, the number of fruits in each plant, the yield of each plant and total yield per unit area) compare to 4.5 ds.m-1 level which gave the lowest values of studied indicators. Spraying 150mg.L-1 of α-Tocopherol was also increased the studied indicators significantly, while, the interaction treatment between the two factors of the experiment was increased the above studied indicators significantly.
