Results of Regional Kentucky Bluegrass Cultivar Trials
Rodney A. St. John and Nick E. Christians
The United States Department of Agriculture (USDA) has sponsored several regional Kentucky bluegrass cultivar trials conducted at most of the northern agricultural experiment stations. The trial was established in the fall of 2000. The area received 4 lb N/1000 ft2/yr, and was irrigated as needed. The objective of this study is to investigate cultivar performance under a cultural regime similar to that used on irrigated home lawns in Iowa.
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. Yearly means of monthly data were taken and are listed in the last column (Mean). The first cultivar received the highest average rating for the entire 2001 season. The cultivars are listed in descending order of mean quality. The last row list the LSD (least significant difference), which is a statistical measurement of how widely the means must vary before they are considered to be different from one another.
Data for genetic color (Gcol) and leaf texture (Leafte) also are included. 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. Grcovsp and grcovfa are measurements of ground cover in spring and fall of 2001 and are measured in % of the ground with grass cover. Pctesta is an estimation of the relative establishment rates of the cultivars and again is measured on a % ground cover basis.
