Sorghum
Sorghum is a genus of numerous species of Poaceae|grasses, some of which are raised for grain and many of which are used as fodder plants either cultivated or as part of pasture. The plants are cultivated in warmer climates worldwide. Species are native to tropical and subtropical regions of all continents in addition to the South West Pacific and Australasia. Sorghum is in the subfamily Panicoideae and the tribe Andropogoneae (the tribe of big bluestem and sugar cane).
For more specific details on commercially exploited Sorghum see commercial sorghum.
Cultivation and uses
Numerous ''Sorghum'' species are used for food (as grain and in Sweet sorghum| sorghum syrup or "sorghum molasses"), fodder, the production of alcoholic beverages, as well as biofuels. Most species are xerophyte|drought tolerant and heat tolerant and are especially important in arid regions. They form an important component of pastures in many tropical regions. ''Sorghum'' species are an important food crop in Africa, Central America, and South Asia and is the "fifth most important cereal crop grown in the world".[Sorghum, U.S. Grains Council.]
A ''sorghum'' species, Johnson grass|Johnson Grass, is classified as a noxious weed.
The reclaimed stalks of the sorghum plant are used to make a decorative millwork material marketed as Kirei board.
Some species of sorghum can contain levels of hydrogen cyanide, hordenine and nitrates lethal to grazing animals in the early stages of the plant's growth. Stressed plants, even at later stages of growth, can also contain toxic levels of cyanide.
In India, and other places, Sweet Sorghumstalks are used for producing bio-fuel by squeezing the juice and then fermenting into ethanol. Texas A&M University in the United States is currently running trials to produce the best varieties for ethanol production from sorghum leaves and stalks in the USA.
