Abstract: This study was conducted to determine the suitable sowing date and intrarow spacing for safflower (Carthamus tinctorius L.) under Harran Plain's arid conditions during the 1998-1999 and 1999-2000 winter growing seasons. Four sowing dates (mid-October, early November, mid-November and early December) and 5 intrarow spacings (5 cm, 10 cm, 15 cm, 20 cm and 25 cm) were applied. Dinçer-118 was used as the safflower cultivar. Seed yield (1191.7-667.5 kg ha^{-1}), oil content (35.48-25.66%), oil yield (389.4-175.9 kg ha^{-1}), shell rate (50.37-39.33%) and 1000-seed weight (36.71-29.22 g) were investigated and all parameters measured were significantly affected by the treatments. The results obtained showed that the most suitable sowing date and intrarow spacing for safflower on Harran Plain were November and 5 cm, respectively.
