Harvest Management |
Do not cut or graze until forage reaches 18" in height. Cut at 24" to 36" for best quality and yield. Cut 6" to 8" above ground level for fastest regrowth. Condition with a crimper at a slight diagonal to speed drying and regrowth. Wilt to 50% to 60% moisture for storage in a bunker or concrete stave silo and 45% to 55% for a sealed storage system. Forage should be about 85% to 90% plant moisture at cutting. Chop at 1/4" to 1/8" cutting length to improve packing. |
