Sorghum sudangrass is a coarse, erect grass with considerable variability in growth characteristics. Leaf blades commonly are similar in shape to those of corn but shorter and wider. Blades are glabrous and waxy.
The greatest dry matter yields for forage are realized when plants are allowed to approach maturity or at least heights of 30 to 50 inches. Although such heights may be considered for silage, green chop or hay, they are not suitable for grazing. Most uniform grazing and least waste are achieved when grazing animals are turned into fields at 8 to 12 inches in height.
All Sorghum and Sudan crops will develop “PRUSSIC ACID” under certain conditions, specifically in very young plants recovering from drought and in plants subject to killing frost.
