Abstract:
Sorghums (Sorghum bicolor) are warm-season grasses native to Africa. They were introduced into the United States in the 17th century. They are grown primarily under dryland conditions or with limited irrigation in the semiarid
southwest and the Great Plains. Grain sorghums generally are cultivated in areas that are too hot and dry for corn because of their ability to withstand drought. Development of early maturing varieties and other
genetic improvements have made it possible to grow the
crop in areas where it could not be grown before.
Worldwide, sorghum mainly is food for humans; but,
in the U.S., grain sorghum serves mainly as feed for
livestock. The U.S. is a major sorghum producer and
exporter, and the crop is second only to corn as a feed crop.
