Determination of Water and Yield relationship is important in irrigation schedule and design. Determination of Water and Yield relationshipwere studied by employing line source sprinkler irrigation system. It includes three duplications, Four treatment distance form irrigation line of I1 (no water stress) to I4 (severe water stress) which were paralleled to irrigation lines. The experiment were conducted in SWRI experimental stations in Meshkin-dasht, Mashhad and Ahwaz during 2007-2011. Soil water content in I2 (soil surface to 60cm) was monitored. Irrigation depth was determined for increasing soil water content to FC. Yield and water application was measured during growth stage. In Karaj, Mashhad and Ahwaz Maximum yield respectively was 4667, 4126 and 4230 Kg/ha,Minimum yield respectively was 3147, 2875 and 1341Kg/ha. The yield response factor (Ky) In Karaj, Mashhad and Ahwaz respectively was 0.44, 0.36 and 0.79.
