Persistence of alfalfa under continuous grazing in pure stands and in mixtures with tall fescue

Some alfalfa (Medicago sativa L.) germplasms and cultivars have shown long-term persistence under continuous grazing in pure stands in the southeastern USA, but interspecies competition with tall fescue (Festuca arundinacea Schreber) may result in stand declines. We tested the persistence and forage productivity of alfalfa cultivars and a germplasm that differed in grazing tolerance under continuous grazing in pure and mixed stands with tall fescue (.)
