Abstract: The dale portion of a dykeland flat constitutes 20 to 40% of a dykeland field. Producers are looking for legume mixtures that are successful on dales. This study evaluates legume-based forage mixtures with grasses seeded on dales for productivity and persistence under two management regimes. The trial seeded at the Nappan Research Farm included three different legume mixtures seeded with timothy: red clover, birdsfoot trefoil, and a three legume mixture of alfalfa, birdsfoot trefoil, and red clover. The New Brunswick farm sites were seeded with four mixtures which included: timothy or smooth brome in mixture with birdsfoot trefoil and red clover. On-farm timothy and smooth brome grass were shown in this study to be successful companion grasses on dales. Birdsfoot trefoil and red clover produced well in mixture with grasses on dales while alfalfa did not persist when seeded on dales. The two-cut management system produced more forage and had a higher legume content after two production years than the one-cut management regime.
