Abstract: Field studies were conducted in 2010 at Saint-Augustin-de-Desmaures and Sainte-Anne-de-Bellevue to compare two crops potentially used for ethanol production (sweet pearl millet/sweet sorghum), two harvest dates (August/September), and four delays between mowing and pressing the biomass (0.5, 2, 4, and 6 hours) for biomass and sugar yields and nutritive value of the forage and silage made with the residue. Sweet sorghum is a better source of sugar than sweet pearl millet. The harvest in August produces a forage and a silage of greater nutritive value, whereas the harvest in September maximizes biomass and sugar yields. The delay between mowing and pressing the biomass had no significant impact on yield and sugar concentration of the juice. Silages made from the pressed forage material of both species were well preserved.
