Influence of grass species and mowing practices on weed cover and quality in infrequently mowed grass stands

Infrequently mowed grass areas on institutional grounds and golf courses can reduce mowing costs impart a natural appearance to the property. However, weed encroachment into these compromise aesthetic appeal of stand increase associated with control. The objective this 2-yr field study was determine influence species frequency cover quality. Six or mixtures were established from seed subjected three treatments at 12.5-cm height: one per year (December); two mowings (April December); (April, June, December). Grass treatment influenced quality all rating dates. Treatments showing least over growing seasons included strong creeping red fescue (Festuca rubra L. ssp. Gaudin) tall arundinacea Schreb). greatest autumn bentgrass [Agrostis perennans (Walt.) Tuckerman]. Mowing did not have significant cover. Stand varied among course for individual species. Autumn bentgrass, little-studied native North America, generally provided poor throughout appeared unsuitable use in infrequently courses. Whereas time study, both provide effective suppression likely serve as acceptable plantings mowed, out-of-play locations that are typically viewed distance large properties.
