Abstract/Contents: | Kentucky bluegrass cultivars 'A-34', 'Baron', 'Bonnieblue', 'Newport', and 'Pennstar' were each seeded at 65, 194, 388, and 1033 pure-live-seed count per dm2 on May 12, 1977. A cutting height factor (1.3 and 2.5 cm) and fungicide factor (preventive fungicide-applied and check) were superimposed over the experimental area. A visual estimate of the area per plot occupied by annual bluegrass was taken five times over a 3 1/2 year period. We found less annual bluegrass at the 2.5 cm cutting height than at the 1.3 cm height. There were significant seeding rate and cultivar effects on annual bluegrass encroachment which lasted for the 3 1/2 years of observation. In general, a cultivar or seeding rate that allowed annual bluegrass encroachment in the first two months, retained that proportion for the entire test. The fungicide-applied and check plots had equal quantities of annual bluegrass at the beginning of the test but these amounts diverged until the check plots had significantly more annual bluegrass after 3 1/2 years. |
