This study was carried out to find the effect of the pinching and planting density on yield of petal and grain in safflower (Caythamus tinctorius L.). The planting density was high effective branch number per ㎡ compared with pinching, and effective flower bud was most in 270 ea/㎡ in three line planting density, but in case of pinching was few at 186~223 ea/㎡. Grain yield was increased with 231 kg/10a at double line planting density compared with in 220 kg/10a of control. Petal yield of double line and three line planting density was 25.4 kg/10a and 26.9 kg/10a, it was increased 15, 22% compared with 22.0 kg/10a of control, respectively.
