BETTER GRASSES FOR ROADSIDES. EXECUTIVE SUMMARY.

Grasses for roadsides generally evolved from agricultural and soil conservation practices. The growing importance of maintenance costs and environmental aesthetics dictate the need to develop better grasses. Over a thousand varieties or strains, including 36 different species of grass, plus mixtures, were established in plots along eight roadsides throughout New Jersey and three Experiment Station sites over five years. Coarse grasses, including Kentucky 31 tall fescue and redtop consistently produced conspicuous persistent seedheads which detract from the appearance of the grassy landscape. Finer turfgrasses, including certain varieties of Kentucky bluegrasses and four fine fescues established readily and produced fewer, and less objectionable seedstalks. Perennial ryegrass varieties produced an abundance of foliage and seedstalks initially, crowded associated grasses excessively, and disappeared after two years of low intensity management. Outstanding performance of spreading fine fescues at several locations prompted the development of a new variety, 'Fortress', synthesized from locally collected elite plants. Commercial production of it, and a superior Chewings variety, 'Banner' are anticipated. Such grasses should improve the quality of roadside mixtures, particularly when used with 'common-type' varieties of Kentucky bluegrasses such as 'Kenblue'. The importance of seed-free mulch is shown. Better appearance with less mowing can be achieved with mixtures of certain varieties of fine fescues and Kentucky bluegrasses.
