Abstract
This study was conducted to investigate the sulfur effects on the yield of safflower (Carthamus tinctorius L.) and the chemical properties of soil after sulfur treatment. Sulfur application was conducted with two chemical forms of sulfur powder and potassium sulfate. Sulfur powder was applied to the soil with levels of 0, 10, 20, 40 kg/10a and potassium sulfate was applied to the soil with levels of 10, 20 kg/10a as sulfur content. After sulfur application in soils, pH and available content of soils tend to decrease after experiment, whereas the contents of and active Fe increased in soils. By the application of sulfur, the yields of safflower seed were increased by about percent compared to the control. It is apparent that seed yield and plant growth of safflower were increased by the sulfur application.
