Abstract: The objective of this research was to increase the ethanol production of sweet sorgum stalks by panicle removal. This field experiment was conducted using a randomized complete block design with three replicates. The first factor was stages of panicle removal (50% booth, 100% flowering, and 50% grain filling) and non-panicle removal as control. The second factor was the variety of sweet sorghum (White Local Belu, Numbu, Kawali and Sugar Graze). Variables measured were seedling emergence, stages of 50% booth, 100% flowering and 50% grain filling, stalk fresh weight, juice production, sugar content (brix), ethanol content and ethanol production. Results showed that panicle removal increased the ethanol content and ethanol production of the three varieties except var. Numbu. Panicle removal at stage of 100% flowering or 50% grain filling resulted in the highest stalk ethanol content and ethanol production. Var. Sugar Graze gave the highest ethanol production (2084.51 L ha-1) when panicle was removed at 100% flowering or 2080.43 L ha-1 when was done at 50% grain filling stages. The ethanol content of var. White Local Belu was lower than those of the other three improved varieties. Keywords: Ethanol, Panicle removal, Sweet sorghum [Sorghum bicolor (L. ) Moench, Varieties
