Digitaria ciliaris (hairy crabgrass)
'Red River' crabgrass is a high quality, high yielding summer annual forage used for grazing and haying.
'Red River' crabgrass was a selection released by the Noble Foundation in 1988. 'Red River' is a high yielding summer annual forage and is the first known crabgrass variety released. 'Red River' is a single plant selection found near the Red River region in southern Oklahoma. 'Red River's area of adaption extends from the subtropical areas of Florida and to the humid to semi arid southeastern to south-central USA. This area encompasses part or all of the twenty-one most southeastern states from Nebraska, south and east to the Gulf and Atlantic coasts to similar climates worldwide. Testing at the Noble Foundation showed 'Red River' yielded 25% to 50% more forage than the native types over several years testing. 'Red River' has tested to be 73% digestible. Crude protein levels begin as high as 25-30% early in the season to 15-20% mid summer and 10% late in the season.
