Sorghum is a genus of plants in the grass family. Most species are native to Australia, with some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. One species is grown for grain, while many others are used as fodder plants, either intentionally cultivated or allowed to grow naturally, inpasture lands. The plants are cultivated in warm climates worldwide and naturalized in many places.
It is an important crop worldwide, used for food, animal fodder, the production of alcoholic beverages, and biofuels. Most varieties are drought- and heat-tolerant, and are especially important in arid regions, where the grain is one of the staples for poor and rural people.
