Meat and Animal Science Sorghums are warm weather crops that originally came from Africa. They have done very well throughout Wisconsin during the 1987 and 1988 seasons because of their drought tolerance and the above average temperatures for the growing seasons.
Sorghums are either annuals or perennials but all act as annuals in Wisconsin.
This type grows 3.5 to 5 feet tall depending on variety and conditions. It is usually not considered for forage production because of low dry matter yield. They usually grow 8 to 13 feet tall. Major use is for silage. Stems and leaves are similar in size to corn.
