Abstract/Contents:"Turfgrass mixtures are used for such reasons as variations in the site or the need for a quick-growing species in the seeding. Kentucky bluegrass, red fescue, and colonial bentgrass were seeded in combination in greenhouse cultures, with and without perennial ryegrass, annual ryegrass, and redtop. The first three species were used in equal number to provide all or the major portion of the seed mixture. Seeding rates ranged from 20 to 60 seeds per square inch. Perennial ryegrass, annual ryegrass, and redtop were included at increasing percentages of mixture and at fixed percentages with varied rates of seeding. Plant samples were taken 8 to 12 weeks after seeding, and the weight of the two largest plants, total weight, and number of shoots were determined. Kentucky bluegrass plants grown in competition with colonial bentgrass at three rates of seeding were significantly larger than those grown in competition with red fescue. Also, colonial bentgrass was reduced in size when grown in competition with red fescue rather than Kentucky bluegrass. The largest plants of Kentucky bluegrass grown in competition with perennial ryegrass were significantly smaller than those grown in competition with red fescue. Also, red fescue grown in competition with perennial ryegrass tended to be smaller than those grown in competition with red fescue. Also, red fescue grown in competition with perennial ryegrass tended to be smaller than those grown in competition with Kentucky bluegrass. Annual ryegrass was more competitive than perennial ryegrass and redtop was less competitve [competitive]. All permanent-type grasses appeared to compete with themselves at rates of seeding used. The study shows Kentucky bluegrass is a very poor competitor in the first 8 to 12 weeks of seedling growth. Red fescue is a stronger competitor and colonial bentgrass a weaker competitor than recognized."
