Seed Yields of Birdsfoot Trefoil, (Lotus corniculatus L.) as Affected by Pre‐Harvest Clipping and by Growing in Association With Three Adapted Grasses1

Synopsis Spring and early summer clipping of birdsfoot trefoil reduced seed yields in comparison to unclipped stands. The association of Kentucky bluegrass, orchardgrass or timothy reduced lodging and increased seed yields of birdsfoot trefoil. Kentucky bluegrass was superior to the other grasses. Two years after seeding, birdsfoot trefoil stands were thicker when grown with a grass than when grown alone. Tall‐growing orchardgrass and timothy tended to delay maturity of the birdsfoot trefoil. After the first harvest year, forage yields were slightly higher when the birdsfoot trefoil was grown with a grass.
