Wheat (Triticum aestivum L.) is one of the main cereal crops in the world together with maize and rice. Drought stress is the most important limiting factor of field crops in Iran. Most parts of Iran’s cultivation land is placed in arid and semiarid regions and because of water deficiency, plant stress appears and wheat performance reduces severely in these regions. The experiment was carried out as Completely Randomized Block under spilt – spilt plot design with three replicates, on loomy fine sand soil during 2001-2002 and 2002- 2003 growth season at the Research Center Institute of Zabol, Zahak. Analysis of variance showed that the effect of cut irrigation, nutrient application and variety on all characteristics was significant. The maximum grain nitrogen of treatments w2 (2.528) was obtained. The minimum grain nitrogen of treatments w1 (2.391) was obtained. Analysis of variance showed that the effect of variety on grain nitrogen was significant. The maximum grain potassium of treatments w2 (0.983) was obtained (Table 2). The minimum grain potassium of treatments w1 (0.879) was obtained.
