Abstract/Contents:1988 update of two tests to evaluate tall fescue varieties under Kentucky climactic conditions. First test was established in 9/82 and includes 46 named and experimental varieties in six replications. Three replications are maintained at a 1.5 inch height and three replications at a 3.0 inch height. Three pounds of nitrogen per 1000 square feet are applied annually during the fall and early winter. Evaluations for 1988 were taken in May and June. Results at 1.5 inches: The top 5 cultivars, Apache, Olympic, Jaguar, Mustang, and Adventure, had: 1) 5-year average (1982-87) visual quality ratings of 7.8 or 7.9 (1 to 9; 9=best quality), 2) from 0.9 to 3.0 tall fescue tillers per sq. in. (measured 12/87), 3) from 67-88% tall fescue on 6/9/88, and 4) less than 14% Kentucky bluegrass on 5/12/88. Olympic had the best overall performance. SoFm blend and Triumph faced poorly in all categories with visual quality less than 5.2, low tillering rates and, low % tall fescue with high % Kentucky bluegrass. Results at 3 inches: In general, overall performance for all varieties was worse at 3 inches. Apache, Jaguar, 52W, Mustang, Olympic, and Adventure were the top 6 cultivars with visual qualty ratings of 7.0 to 7.3, 0.2 to 0.8 tillers per sq. in., less than 13% tall fescue and greater than 18% Kentucky bluegrass. Triumph and SoFm blend again showed the worst overall performance. The first test was concluded in 1988. The second test was established in 9/83 and is included in the National Tall Fescue Variety Test. Fifty-four experimental and named cultivars were seeded in three replications at the rate of 4.65 pounds per 1000 square feet and are maintained at 1.5 inch height. Three pounds of nitrogen per 1000 square feet have been applied annually during the fall and early winter. Annual and 5-year average visual quality ratings are provided for 1984-88 with a least significant difference value in 1988. 5-year average ratings (1 to 9; 9=best quality) ranged from 3.3 for Kenhy to 6.3 for Finelawn 5GL. Falcon, Adventure, Unknown, Arid, Mustang, and Apache all had ratings of 6.0 or greater.
