Haygrazers are crosses of forage types of sorghum, sorgo, and sudangrasses. Haygrazers grow rapidly and become stockpiles. Stockpiles are excellent for grazing in summer months. Haygrazers that are fertilized are the highest-quality. They also tend to be deep, well-drained and are planted thicker. The crude protein is between 7-14%, and it can yield 2-5 tons per acre.
