1 2001 NTEP Tall Fescue Test 2002 Results Dan Weisenberger Objective Rationale How It Was Done To evaluate commercial and experimental varieties of turf-type tall fescue under high maintenance conditions in central Indiana. Turf-type tall fescue has many attributes such as very good drought tolerance, very good heat tolerance, moderate cold tolerance, and good wear tolerance that make it a good choice for many turf sites. Tall fescue will form a dense, attractive turf stand when properly maintained. By determining the performance of the 160 varieties, we will be able to offer sound information on which varieties of turf-type tall fescue to plant in Indiana. One hundred and sixty varieties of turf-type tall fescue were seeded on 5 Sep 2001 at the William H. Daniel Research and Diagnostic Center on a silt loam soil. Seeding rate was 5.2 lbs per 1000 ft 2 and seed was spread using a hand shaker jar. After seeding the experiment was lightly raked and a starter fertilizer ( ) was applied at the rate of 1.5 lbs P 2 O 5 per 1000 ft 2. The area was covered with a germination blanket following seeding to prevent washing of seed and mixing of varieties. The plots will be maintained under a high maintenance regime, typical of a home lawn. The mowing height will be 2 inches, mowed twice per week. The annual fertilization will be 3.5 lbs. N per 1000 ft 2 with 1 lb applied in mid-may, 1 lb in mid-september, and 1.5 lbs. in early November. Irrigation will be applied to prevent any sign of stress. Data collected in 2002 included genetic color, leaf texture, percent living ground cover, brown patch, and visual quality ratings from Apr to Nov. All data taken were visual observations of turf characteristics and performance. Visual quality ratings were taken using a scale of 1 to 9 with 1 = no living turf, 5 = acceptable turf, and 9 = ideal turf. Results to Date There are no statistical differences in average visual quality among the top 30 cultivars (Table 1). Brown patch can be a severe disease on turf-type tall fescue. When rated on July 8 there were no statistical differences between the top 104 cultivars. There were no statistical differences between the top 65 cultivars for percent cover when rated on May 28. It is still early in this test to make definite recommendations for IN. When making cultivar selections, it is best to consult the NTEP web page at for complete performance data from around the country on cultivars, placing special emphasis on how cultivars perform in IN, IL, KY, MI and/or OH (depending if you are located in northern, central, or southern IN) under the specific maintenance regime you intend for that grass. 36
