The effect of sulfometuron-methyl as chemical ripener on growth and yield of three sweet sorghum cultivars was investigated. The results revealed that for three sweet sorghumcultivars, growth and yield of Ethanol 2 cultivar were largest and followed by KKU 40 and Cowley cultivars, respectively. Sulfometuron-methyl mainly affected on growth and yield of sweet sorghum. As different sulfometuron-methyl concentration levels, the increasing doses of sulfometuron-methyl concentration were decreased the growth and yield of sweet sorghum. Juice extract yield, brix degree and stem fresh weight yield of sweet sorghum were the largest at 1,000 mg lit-1 sulfometuron-methyl concentration when compared to the other concentration and control treatment. However, it was recommended that the most suitable application of sulfometuron-methyl was 1,000 mg lit-1 concentration with Ethanol 2 cultivar. In addition, all of the growth parameters, It was not found the interaction between sulfometuron-methyl concentrations and sweet sorghum cultivars.
