This study was carried out to clarify the effect of sulfur fertilization method on the qualities of safflower (Carthamus tinctorious L.) seed. Sulfur application increased the nitrogen and sulfur content of seed. In nitrogen content, there was no significant difference among sulfur fertilizers, whereas sulfur content was increased by raising ammonium sulfate (AS) amounts by soil application. In application method of AS, there was no significantly difference between foliar application and soil application with 8 kg S/10a. N/S ratio in seed was decreased by sulfur application, and also decreased with the increase of AS amounts by soil application. The contents of lipid and protein were increased by sulfur application. Lipid content was highest in foliar application, and protein content was lowest in AS 4 kg S/10a. By sulfur application, the content of total phenolics and electron donating ability (EDA) were increased by 3.1{sim}4.7% and 3.6{sim}8.5%, respectively compared with control. In content of total phenolics, there was no significant difference among sulfur fertilizers, but EDA was higher in sulfur powder 20 kg/10a and AS 8 kg S/10a than that in other fertilizers. Sulfur application showed positive effects on the qualities of safflower seed. In application effects, AS and foliar application were more efficient than sulfur powder and soil application, respectively.
