Sorghum bicolor, commonly called sorghum and also known as broomcorn, great millet, Indian millet, Guinea corn, jowar, or milo is a species in the grass genus Sorghum cultivated chiefly for its grain. It is native to Africa and the Indian Subcontinent. The grain is used as food by humans, while the plant is used for animal feed and ethanol production. The stalk of sweet sorghum varieties, called sorgo or sorgho and taller than those grown for grain, can be used for forage or silage or crushed for juice that can be boiled down into edible syrup or fermented into ethanol.
