Currently there are five major types of sorghum grown: 1) Grain sorghum with dwarf varieties that grow 2 to 5 ft tall for easier combining. 2) Forage sorghum which grows 6 to 12 ft tall, produces more dry matter tonnage than grain sorghum, is coarse stemmed and used for silage.
Large acreages of grain sorghum are also grown in Africa and Asia in areas where the climate is too hot and dry for corn. During the past 25 years, the grain sorghum acreage in the U.S. has ranged from 15 to 18 million acres per year.Grain sorghum acreage is somewhat greater than acreages for oats and barley, but considerably less than the land area planted to corn, wheat, and soybeans.arge acreages of grain sorghum are also grown in Africa and Asia in areas where the climate is too hot and dry for corn.
