Abstract A field experiment was conducted to determine the effect of water quality of (1.2.8 ds.m-1) as a main plot and to test two cultivars dill of Iranian and French as a sub-plot. Fertilizer mixtures from interaction of organic fertilizer and Potassium humate were used as a sub-sub-plot to study growth and yield traits, In addition, an evaluation of the tolerance level of the dill plant for salt stress was conducted for the absence of salt stress tests on the dill plant in middle and southern Iraq. The experiment was designed within the Randomized Complete Block Design (RCBD) according to the Spilt-Split Plot. The results of the study showed that the salinity of irrigation water caused a decrease in all vegetative and yield traits. The quality of fresh irrigation water was excelled in all studied traits. The results showed significant differences between the Iranian and French cultivars in some of the mentioned traits. Where the Iranian cultivar achieved the highest averages in the dry weight of the root system and the percentage of nitrogen while French cultivar has excelled in the number of leaves and total yield, Fertilizer combinations achieved significant differences, where the interaction treatment between potassium humate and rice wastes compost was significantly excelled in most vegetative traits, especially under salt stress.
