摘要

Overseeding established kikuyugrass swards with tall fescue or perennial ryegrass reduced kikuyugrass cover. Renovation prior to seeding did not aid in the establishment of these two species. Increasing the seeding rate from 79 to 157 kg/ha improved the establishment of perennial ryegrass but Not tall fescue. When kikuyugrass plugs were introduced into established turf, tall fescue reduced the Invasion of kikuyugrass stolons more than perennial ryegrass. Tall fescue reduced percent kikuyugrass Cover, number and spread of stolons, and biomass (compared to perennial ryegrass).
