The purpose of this study was to determine response of safflower cultivars to weed and the row spacing. The experimental design was used a split-split plot arrangement in a completely randomized block with 3 replications. Main plots were cultivars (5-118 and 5-154), sub plots were weed treatment (weed not removed and weed removed manually) and sub-sub plots were row spacing (20, 40 and 60 cm). The hand weeding decreased the weed density by , conversely increased the safflower yield by . The highest seed yield ( kg da -1) was obtained for cv. 5-118 at 20 cm. However, for cv. 5-154 the highest yield ( kg da -1) was obtained at 20 or 40 cm row spacings. Plant height, number of branches plant -1, number of heads plant -1 and head diameter were always more closely associated with high yields of each cultivar than seed weight. Planting of the cv. 5-118 was recommended at 20 cm row spacing because of better competetion with weeds and it’s higher yield than cv. 5-154. This cultivar is also more suitable to hand harvesting due to it’s spinelessness. Yazlık Ekimde Aspirin (Carthamus tinctorius L.)
