Performance of Turfgrass Cultivars in Multiple Northern U.S. Roadside Environments

Abstract

Survival of turf along roadsides is a challenge in many states in the central and northern U.S. due to stresses that include high levels of salt from deicing operations, drought stress from a lack of irrigation, and temperature extremes. State departments of transportation recommend mixtures for various roadside environments; however, many of these mixture recommendations are either outdated or are developed without supporting research data collected by an unbiased source. The objective of this study was to assess potential roadside turfgrasses across multiple states in the northern U.S. to generate unbiased data for use by public agencies.
