Observations of 20-Plus Cover Crop Species

Cover crops span a diverse array of plant types and species, and they can be used at various times of the year in the Southern Great Plains. For the sake of simplicity, we will group them by warm-season and cool-season. Typically, cool-season cover crops are planted in the fall on crop fields or overseeded into dormant warm-season perennial grass pastures. Warm-season cover crops are usually planted in the spring on crop fields. In Oklahoma and Texas, they can also be planted in late summer for fall growth prior to a killing frost. We have experimented with growing cover crops in various environments in the Ardmore, Oklahoma, area over the past several years. Following are some of our observations.

Management of Annual Ryegrass

Ryegrasses are productive, high quality cool season forages that are either perennial or annual in their growth. The perennial ryegrasses are grown throughout much of the midwestern and northern U.S. for pasture and turf. The use of perennial ryegrass in the southern U.S. is limited by the lack of persistent and productive varieties. Perennial ryegrass is sometimes used in the mid- to upper South as an annual because it is more winter hardy than annual ryegrass.
