Abstract/Contents:Research is being done to determine tall fescue (Festuca arundinacea) cultivar characteristics in relation to sun and shade. The sun research is only two years old and the shade research is one year old. A minimum of six years is needed for reliable data to be obtained. Tall fescue is already known for its excellent drought tolerance and its ability to grow in infertile soils. Tall fescue also has excellent wear tolerance. With these excellent characteristics, tall fescue would seem to be a good choice for turf applications. Research started in November 1981 by seeding 14 cultivars in the full sun plots. In November 1982, those same 14 cultivars were seeded in the full shade plots. All plots were seeded at a rate of nine pounds of seed per 1000 sq. ft. Plots were maintained with weekly mowings at 2 inches and clippings removed. Nitrogen was applied at a rate of one lb. per 1000 sq. ft. from March through November only. Whatever potassium and phosphorous was needed, dictated by annual soil tests, was added. No pesticides were added. Results of the turf quality were based on: (A) uniformity of color and (B) shoot density. A scale from 1 to 9, (9 = best, 1 = poorest, and a 5 rating or better representing acceptable performance) was used. The full sun research plots maintained a high quality rating from January to May and through the spring. Warm weather in July and August saw a drop in ratings and water was required. In early September, pythium attacked the plots and it was found that the Kenmont cultivar resisted pythium best. Other cultivars such as Galway, Brookston, and Clemfine had a high susceptibility to pythium. By November all plots had recovered well. In the shade study all cultivars quality ratings were high until spring, but in July the quality ratings dropped off substantially. During this time, only cultivars Fawn and Rebel produced high enough ratings for a lawn cover. In August, all were hit with rust disease (Puccina spp.) and no resistance was seen by any cultivar. September brought Pythium and only a few shoots survived. By the following March, the plots had recovered.
