Abstract/Contents:"It was the intent of this test to determine the severity of the competition/allelopathic effects of perennial ryegrass on the establishment of another variety of perennial ryegrass and on both tall fescue and Kentucky bluegrass. This test was not designed to separate competition effects from allelopathic effects but it was conducted in a very thin, nitrogen-deficient stand of perennial ryegrasss in which intra-plant competition was minimized." "Two pounds per 1000 sq. ft. of Adelphi Kentucky Bluegrass, Jaguar Tall Fescue, and Pennant Perennial Ryegrass were seeded in a split plot design with three replications and three seeding methods: (1) slit-seeding using a Salasco Seeder, (2) broadcast seeded and top-dressed with approximately 1/8 inch of topsoil, and (3) prepared (tilled) seedbed. One-half of each plot was treated with Roundup (glyphosphate) ten days before seeding (April 10, 1992)." Includes two tables which provide the percent turf cover and percent establishment for each plot. This test "indicated that allelopathy may be a serious problem when mono-stands of perennial ryegrass are established. Although variety differences, soil types, and seeding season differences exist, this test would indicate that, if one is renovating a mono-stand of perennial ryegrass, the area should not be slit-seeded with either Kentucky bluegrass or tall fescue unless the perennial ryegrass is first killed with Roundup. Also, if preparing a seedbed from a pure stand of perennial ryegrass, the ryegrass should be killed with Roundup before tillage."
