A vast area of Iran is in the warm and dry climatic region of the world. Addition of amendments to soil for increasing water use efficiency, soil water retention and improving soil physical properties is one of the most important ways to cope with water scarcity. Among these materials, natural amendments such as poultry manure and zeolite can be mentioned. These modifiers are actually water storage treatments in the soil and can retain water for a longer time to the plant. One of the basic ways to exploit soils in saline areas is planting halophytes and salinity resistant products. Salicornia is one of the halophytes extremely tolerant to salinity conditions. This research with the aim of evaluating the indigenous specie yield of Salicornia persica under irrigation with different levels of salinity in a sandy soil was conducted in the greenhouses of the College of Agriculture, Isfahan University of Technology, in 2018. The experiment was conducted in a completely randomized design with 3 replications. The experiment consisted of 13 treatments with 4 and 8 percent zeolite treatments and 4 and 6 percent poultry manure at levels of 4 and 6 wt% as water retention treatments in soil. Salinity stress by irrigation water were in 6 levels of 80, 160 and 200 mM for the 4 percent and 400, 600 and 800 mM for the 6 and 8 percent water retention treatments. The 800 mM salinity treatment resulted in the maximum amount of sodium in shoots for both soil water retention treatments. Different levels of salinity stress had a significant and decreasing effect on the shoot potassium to sodium ratio. Generally, the trend reduction of the shoot potassium to sodium ratio by increasing salinity, as well as increased accumulation of sodium ion in the vacuoles and transferring to the shoot in order to regulating osmotic pressure of cells, indicate the salinity tolerance of Salicornia persica . Salicornia persica plant showed to be able to survive very well in high salinity conditions (400 to 600 mM) salinity. The highest rate of water use efficiency in poultry manure treatment was under the irrigation with a salinity level of 600 mM , which was increasing 49 percent relative to the control. The highest amount of soil salinity was in the poultry manure treatment. Evaluation of the soil water characteristic curve showed that with increasing EC in all matric suctions, the amount of moisture retained in soils treated with poultry manure, was higher than the zeolite treatment.
