The study was carried out at NARC Islamabad during August, 2017 to October, 2017 to investigate the impact of salinity on growth 4 olive varieties i.e. Uslo, Coratina, Carolea and Moraila having 3 months sprouted olive cuttings under different saline water in tunnel. Six levels of saline water artificially developed (ECw= 0,2,4,6,8,10 dSm^-1). Completely randomized design was applied with three replications. Olive cuttings were irrigated with six saline water three times in a week. Results of this study indicated that Cortiana Olive variety attained the highest values in stem diameter, root fresh weight, root dry weight and stem dry weight growth parameters while Carolea Olive variety attained the best in roots dry weight, leaf fresh weight, leaf dry weight, shoot fresh weight, shoot dry weight and leaf area under the irrigation of different saline water. Chlorophyll contents were the highest in Uslo olive variety in all saline water application.
