Sweet sorghum is any of the many varieties of the sorghum grass whose stalks have a high sugar content. Sweet sorghum thrives better under drier and warmer conditions than many other crops and is grown primarily for forage, silage, and syrup production. Sweet sorghum syrup is known as sorghum molasses in some regions of the United States, though in most of the U.S. the term molasses refers to a sweet syrupy byproduct of sugarcane or sugar beet sugar extraction. Cultivation Sweet sorghum has been widely cultivated in the U.S. since the 1850s for use in sweeteners, primarily in the form of sorghum syrup. In 1857 James F. C. Hyde wrote, "Few subjects are of greater importance to us, as a people, than the producing of sugar; for no country in the world consumes so much as the United States, in proportion to its population." The price of sugar was rising because of decreased production in the British West Indies and more demand for confectionery and fruit preserves, and the United States was actively searching for a sugar plant that could be produced in northern states. The "Chinese sugar-cane" as it was called was viewed as a plant that would be productive and high-yielding in that region. In the early 1860s, the American Civil War not only disrupted both interstate and maritime commerce but also diverted commodities from civilian to military purchases; these factors rendered some food and fiber supplies, including sugar cane and the sugar and molasses made from it, unreliable and expensive. In particular, the South was under naval blockade by the Union navy, making importation of Caribbean cane sugar and molasses expensive and scarce via blockade running. Under these conditions, some farms grew sweet sorghum for syrup to substitute for cane sugar and molasses, which helped ensconce sweet sorghum in Southern food culture. At the same time, anti-slavery families boycotting sweeteners made under slavery as "blood-stained" could grow sorghum and make the syrup in the North, so it was not solely a Southern foodstuff. By the early 1900s, the U.S. produced of sweet sorghum syrup annually. Making syrup from sorghum (as from sugar cane) is heavily labor-intensive. Following World War II, with the declining availability of farm labor, sorghum syrup production fell drastically. Currently, less than are produced annually in the U.S. In Central India it was introduced in the early 1970s by Nimbkar Agricultural Research Institute for
