Abstract: Water availability for agriculture is being reduced as a consequence of global climate change, environmental pollution and growing demand for other uses. Therefore, great emphasis is placed on crop management for dry conditions with the aim of increasing water use efficiency. To see how restricted irrigation systems effect water use efficiency and corn yield, field experiment was conducted for 2 years 2007and 2008 in an semi arid area in North of Syria at the National Research Center in Tel Hadia, partial root-zone drying (PRD), an innovative irrigation system in which both halves of the root system are alternately dried and well watered, was compared with two deficit irrigation levels 85%, 65% and full irrigation 100% from field capacity. Results indicated that there are high significant differences between irrigation treatments (p
