| Abstract/Contents: | "This experiment is a continuation of five years of research carried out at the Cambridge Research station. The previous showed that improving nitrogen fertility reduced weed infestation in all turf species. Species differed in their ability to resist weed invasion, perennial ryegrass being the most resistant, but cultivars differed little in their ability to resist weed invasion. In this experiment, Liberty Kentucky bluegrass, Vista creeping red fescue, Yorktown III perennial ryegrass and Jaguar Iitall fescue were sown in pure stands, two-species mixes and three-species mixes, in 1 m x 25 m plots. Nine commercial mixes were also sown: Pickseed Perfection, Pickseed Futura blue, Rothwell Elite, Rothwell Sunny Mix, Oseco 40% Nublue, Oseco HB-3, Canadian Tire All Purpose, Pro Hardware Pro-proven, and Home Hardware mix. A total of 46 treatments were sown, replicated 4 times. Five 5 m x 100 m fertility treatments were imposed across the species strips. These were (1) no nitrogen fertility, (2) 50 kg N/ha applied in November, (3) 50 kg N/ha applied in November and 50 kg N/ha in late May, (4) 50 kg N/ha applied in November and 25 kg N/ha in late May and mid August, and (5) 50 kg N/ha applied every 7 weeks for a total of 4 applications. All plots received the same amount of potassium and phosphorus." |
