Regional Tall Fescue Cultivar Evaluation - Established 1996

Nick. E. Christians and James R. Dickson

This was the first year of data collection from the new tall fescue trial. This is a National Turfgrass Evaluation Program (NTEP) trial. It is being conducted at many locations around the U.S. The purpose of the trial is to study the regional adaptation of 129 tall fescue cultivars. Cultivars were evaluated for seedling vigor in October. The study is established in full sun. Three replications of the 3 x 5 ft (15 ft²) plots were established for each cultivar in the spring of 1996. The trial is maintained at a 2-inch mowing height, 3 lbs N/1000 ft² were applied during the growing season, and the area was irrigated when needed to prevent drought. Preemergence herbicide was applied once in the spring.

Seedling vigor (Svig) was rated on a 9 to 1 scale: 9 = best vigor and 1 = worst vigor. Turf quality was evaluated for May through October and was assessed on a 9 to 1 scale: 9 = best quality, 6 = lowest acceptable, and 1 = poorest quality. Genetic color (Gcol), greenup (Grnp), and leaf texture (Ltex) data also are included.

Initial establishment was poor due to damage in the winter of 1996-97 and none of the cultivars had a satisfactory quality rating for the entire season. The September and October ratings show that several of the varieties were well established by the fall of 1997.
