Abstract/Contents:1981 update of 3 tests to evaluate tall fescue varieties in Kentucky climactic conditions. Test 1 was established in 1976 and includes 10 cultivars with 3 replications each. These cultivars are maintained at a 2 inch height and without irrigation. Three pounds of Nitrogen per 1000 sq. ft. have been applied annually during the fall and early winter. Both a broadleaf weed and crabgrass preemergent herbicide are applied annually. During 10/81, density and percent of tall fescue tillers were determined from 4" diameter plugs removed from each plot. A table provides tiller results and 1977-81 annual and 5-year average visual quality ratings (1 to 9;9=best quality) with significant differences indicated for 1981. Rebel had highest % tillers (83) and best 5-year average ratings (7.3). Momm Fa-8 had lowest % tillers (45) and worst 5-year average ratings (5.8). Test 2 was established 9/78 and was included as a part of the Southern Regional Tall Fescue Test. Nineteen varieties were seeded in 3 replications. Maintenance and data collection were similar to that described for Test 1. Tables provide number and % tall fescue tillers counted from 4" plugs in 10/81, March to October 1981 monthly, and 1979-81 annual and 3-year average visual quality ratings (1 to 9;9=best quality). % tillers ranged from 39(Goar) to 95(Rebel) while 3-year average ratings ranged from 4.9(Goar) to 7.6(Rebel). Test 3 was established 9/79 and consists of 30 varieties including a group of experimentals from the breeding program of Dr. R. C. Buckner. These plots have been maintained at a 2 1/2 inch height with 1 1/2 lbs. of N per 1000 sq. ft. per year. Although the quality has been excellent, varietal differences have been minimal. It appears that the high height and low nitrogen fertility mask differences that are normally obtained under a higher management program.
