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