Red River is an improved crabgrass that thrives during the summer months. Crabgrass is a high quality, high yielding summer annual forage that is excellent for grazing and haying. This variety of crabgrass produces a highly digestible forage (up to 73% NDFd) and high crude protein content (25-30% early season; 15-20% mid-summer; 10% late season). Areas of adaption extend from Nebraska, south and east to the Gulf and Atlantic coasts. Great for revitalizing summer pastures.
