摘要

Component yields and forage quality were evaluated in established stands of alfalfa seeded alone and in binary mixtures with smooth bromegrass, orchardgrass, or timothy. Forage yields and quality were determined at three annual harvests in the third and fourth years after seeding. Weed yields in alfalfa seeded alone were significantly greater than those in the alfalfa-orchardgrass mixture. Average weed content was 24, 17, 2, and 15/100 for the alfalfa seeded alone, alfalfa-bromegrass, Alfalfa-orchardgrass, and alfalfa-timothy, respectively.
