Abstract :Safflower insert ignore into journalissuearticles values( Carthamus tinctorius L.); can be a potential oilseed crop for the low-rainfall areas of Central Anatolia, Turkey. 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 insert ignore into journalissuearticles values(5-118 and 5-154);, sub plots were weed treatment insert ignore into journalissuearticles values(weed not removed and weed removed manually); and sub-sub plots were row spacing insert ignore into journalissuearticles values(20, 40 and 60 cm);. The hand weeding decreased the weed density by 75.3%, conversely increased the safflower yield by 36.3%. The highest seed yield insert ignore into journalissuearticles values(128.9 kg da -1 ); was obtained for cv. 5-118 at 20 cm. However, for cv. 5-154 the highest yield insert ignore into journalissuearticles values(72.0 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.
