The main objective of this study was to investigate the proper water regime of sesame crop under different irrigation methods in sandy soil in Egypt, Bostan West Delta. Two successive growing seasons of sesame production were conductedduring2013 and2014 by the use of splitplot design. The irrigation regime treatments were to apply 80%, 100% and 120% of the crop evapotranspiration. The three methods of irrigation were drip surface, drip subsurface and sprinkler methods. The irrigation intervals were 2 days and 4 days for the drip and sprinkler systems respectively. A seasonal water consumptive use by sesame were 490, 465 and 525 mm/season for drip surface, drip subsurface and sprinkler irrigation system respectively. Average irrigation applied water was 2641m3 /fed, 2496 m3 /fed and 4193 m3 /fed by the drip surface, drip subsurface and sprinkler systems respectively. The corresponding average seed yields were 557, 555 and 585 kg/fed. Significant difference was found in seed production due to the irrigation system and the irrigation regime. The average oil yields were 237, 244 and 249.8 kg/fed for the same previous order. The WUE of seeds and .oil affected significantly by both the irrigation systems and irrigation regime
