Maturity Groups of Sudan Grass

Sorghum x drummondii (Steud.) Millsp. & Chase

Classification of Sudan grass based on the duration of the period from emergence to heading, which determines the strategy for utilizing the variety in crop rotation.

In the reference 49 varieties crop Sudangrass, where this is mentioned in the description.

Sudan grass maturity groups are determined based on the phenological indicator of the duration of the "emergence-to-heading" period, measured in days. In scientific practice, early-maturing forms include specimens with a period of 39–40 days, early-ripening ones — 45–47 days, medium-early — 51–55 days, and mid-maturing ones — 58 days or more.

The choice of maturity group is a determining factor in the economic efficiency of the crop. Late-maturing varieties possess a higher green mass yield, whereas early-maturing ones provide an early green forage supply, the possibility of 2–3 cuttings of aftermath per season, and guaranteed seed ripening in various climatic zones.
