Abstract: The objective of this study was to determine the effect of irrigation method and row spacing on yield and several yield components of Local dark sesame in Sanliurfa (Turkey) in 1998 and 1999. Experiments were designed in a split plot. The main plots were two irrigation methods (sprinkle and drip) and the split plots were four row spacings (500-300, 700-300, 800-400 and 700-700 mm) with three replications. The results showed that the yield, plant height and number of capsules per plant were significantly affected by irrigation methods and row spacing. Means of sesame yields in two years were 1440 and 1732 kg ha-1 sprinkle and drip irrigation, respectively. The highest yield was observed at 500-300 mm (1913 kg ha-1) treatment of plant density and the lowest yield was at 700 mm (1220 kg ha-1) row space.
