‘Ioreed,’ ‘Frontier,’ and ‘Common,’ three cultivars of reed canarygrass, Phalaris arundinacea L., each grown at four rates of N, were evaluated for dry‐matter yield, percentage of crude protein, and in vitro dry‐matter disappearance (IVDMD). Nitrogen was applied at 75, 150, 300, and 600 kg/ha/yr. There was a large increase in dry‐matter yield and percentage of crude protein in response to increased N fertilizer, but IVDMD was not affected by N rate. Differences between cultivars were small for all traits. Interactions between N rates and cultivars involving dry‐matter yield existed but did not change the ranking of cultivars.
