Two experiments were conducted to determine the nutritional quality of orchardgrass (OG) cultivars under hay and rotational grazing systems during the first 2 production years. Crude protein content was higher and fibre content lower in OG managed as rotationally grazed pasture compared with that harvested as hay. The K:Ca + Mg ratio was reduced and Cu deficiency was ameliorated when OG swards contained white clover. Orchardgrass genotypic × sward management effects were also observed. Key words: Orchardgrass, management, potassium, genotypes, quality, pasture, hay
