Winter hardiness and management of velvet bentgrass (Agrostis canina) on putting greens in northern environments

Abstract

This is a report from the first experimental year of the project ‘VELVET GREEN - Winter hardiness and management of velvet bentgrass (Agrostis canina) on putting greens in northern environments’. The report is divided into three parts, the first giving results from evaluation of winter hardiness of velvet bentgrass under controlled conditions, the second describing experimental layout and preliminary results from two field trials with fertilizer levels, thatch control methods and topdressing levels; and the third describing experimental layout and preliminary results from a lysimeter study on irrigation stategies for velvet bentgrass on greens varying in rootzone composition.
