Sorghum-Sudangrass

Sorghum

Technical Data Sheet

Description

With usage as hay, silage, pasture, or green chop, Sorghum-sudangrass has very high yield potential under adequate rainfall or irrigation. Yields are highly dependent on the timing and distribution of moisture throughout the growing season. Spring vs. summer planting will also affect the results of sorghum-sudangrass plantings with spring seedings resulting in higher production. In areas with hotter temperatures, sorghum-sudangrass will typically outperform corn plantings.
