Sweet BMR – Palatable Choice for Cattle This BMR hybrid has exceptional sweetness and is a cut above other full season forage sorghums. The stems are larger than sorghum sudan hybrids, resulting in excellent resistance to lodging. It also retains its large, dark green leaves throughout the growing season. This hybrid is partially sterile, thus does not produce significant amounts of grain. This causes a substantial build-up of nonstructural carbohydrates in the stem and leaves. Consequently, the entire plant is more palatable to cattle.
