2001 Tall Fescue Cultivar Trial

Shui-zhang Fei and Rodney A. St. John

This is the second full year of the tall fescue trial that was established in September 2001 and is part of the National Turfgrass Evaluation Program (NTEP). Similar trials are being conducted at many different locations around the US. The purpose of this trial is to evaluate the regional adaptation of 160 tall fescue cultivars under non-irrigated conditions with 2 lbs N /1000 ft² per year and a mowing height of 2.5-3.5”.

The visual quality was evaluated monthly in 2003 from May through October (Table 1).  The values listed under each month in Table 1 are the averages of visual quality ratings made on three replicated plots.  Visual quality was based on a scale of 9 to 1:  9 = best quality, 6 = lowest acceptable quality, and 1 = worst quality.  The yearly average of the monthly data for each cultivar was calculated and is listed in the last column (Mean).  The first cultivar listed in Table 1 had the highest average visual quality rating for the entire 2003 season.  The cultivars are listed in descending order by average quality.  The last row states the LSD (least significant difference), which is a statistical measurement of how widely the datum in each column must vary before they are considered to be different from one another.

Data for genetic color (Gen Color) and leaf texture (Leaf Tex) were also collected in June 2003.  Genetic color was rated using a 9 to 1 scale with 9 = dark and 1 = light green.  Leaf texture was assessed with a 9 to 1 scale with 9 = fine and 1 = coarse texture.
