Ten cultivars of Italian ryegrass ( Loliumultiflorum ) were assessed over two seasons under a cutting regime and a cattle grazing system. A high correlation between the two managements was obtained in respect of annual production, the ranking order of yield being similar in each case for the range of cultivars. Persistence under grazing was highly correlated to that under cutting when assessed at the end of the experiment. There was, however, some evidence of interaction between the two systems in the performanee of one cultivar. The results are discussed in the context of herbage cultivar evaluation for the purpose of recommending those most suitable for general use.
