Abstract: In this study, the cultivation substrate was the main factor (sandy, clay, compost) and drought stress in four control levels and -0.3, -0.6, -1, and -1.5 MPa of soil water potential in three replicates in the form of a split plot.will come This study was conducted at the Experimental Farm of the faculty of desert of Semnan University located in Iran during the winter and spring seasons of 2004.First, the physical and texture properties of soils, chemical properties and exchangeable ions, and some biochemical properties of enzymes such as urease are measured.Duncan's test will be used under SPSS conditions to compare the means and relationships between growth components and the effects of drought stress.The evaluated traits include potato yield, plant height, number of plant branches, number of tubers per plant, potato tuber weight average, tuber size, and production leaf area.The results have shown that the evaluated traits are significantly influenced by the type of soil texture., and water stress and the mutual effect of these two factors.So, under non-limited water resources conditions, clay sand produces the highest yield under full irrigation but water-saving irrigations are not recommended due to considerable loss (50%) in potato yield.
