Soybean Production in Mississippi
What are the recommended maturity groups for Mississippi?
Traditionally, determinate varieties (Group V and later) have been planted in the southern states while the northern states planted indeterminate varieties (Group IV and earlier). Research conducted in Texas, Arkansas, and Mississippi shows advantages to using earlier maturing varieties in the South as well. In 1980, maturity Groups VI and VII varieties were planted to 90 percent of soybean acres in Mississippi. However, today more than 90 percent of Mississippi soybean acres are planted with maturity Groups IV and V varieties.
