Vegetation period of Sudangrass

Sorghum x drummondii (Steud.) Millsp. & Chase

The vegetation period of Sudangrass ranges from 85 to 130 days and is a determining factor for scheduling harvests and assessing crop productivity. Its duration critically affects feed quality and the plant's ability to produce regrowth.

In the reference 12 varieties crop Sudangrass, where this is mentioned in the description.

To evaluate varieties, observations are made of interphase periods, the most important of which are 'emergence to heading,' which determines green mass yield formation, and 'heading to flowering,' which significantly influences the total duration of the vegetation period. Early-maturing varieties allow for faster harvesting, while late-maturing ones are characterized by more intensive biomass accumulation due to a prolonged active tillering phase.

The optimal period for obtaining high-quality feed with a high protein content is the phase from the end of jointing to the beginning of heading. Timely mowing during this period promotes intensive regrowth, allowing for 2–5 cuts per season. The duration of interphase periods depends directly on agroclimatic conditions: high temperatures accelerate plant development, while sufficient moisture levels contribute to the lengthening of the vegetation period.
