1999 Iowa Turfgrass Research Report

This was the final year of data from the '93 fine fescue trial. This was a National Turfgrass Evaluation Program (NTEP) trial. It was conducted at many locations around the U.S. The purpose of the trial was to study the regional adaptation of 59 fineleaf fescue cultivars. Cultivars were evaluated for quality each month of the growing season through August. The study was conducted in full sun. Three replications of the 3 x 5 ft (15 ft²) plots were established for each cultivar in September of 1993. The trial was maintained at a 2-inch mowing height, fertilized with 3.5 lbs N/1000 ft² during the growing season, and irrigated when needed to prevent drought. Preemergence herbicide was applied once in the spring.

Visual quality was evaluated monthly in 1998 from May through August. Quality was assessed using a 9 to 1 with 9 = best , 6 = lowest acceptable, and 1 = worst quality. Genetic color was rated in August using a 9 to 1 scale with 9 = darkest and 1 = lightest green.

A new fine fescue trial was initiated in September 1998. Seventy-nine fineleaf fescue cultivars were established for evaluation. The study was arranged in full sun with three replications and individual plot size of 5 x 5 ft. Percentage fall living ground cover data were taken in October.
