Results of Regional Kentucky Bluegrass Cultivar Trials
Nick E. Christians, David D. Minner, and James R. Dickson
The United States Department of Agriculture (USDA) has sponsored several regional Kentucky bluegrass cultivar trials conducted at most of the northern agricultural experiment stations. Three trials were underway at Iowa State University during the 1998 season. The first, a high-maintenance study, was established in 1995, and received 4 lb N/1000 ft2/yr, and is irrigated as needed. The second trial was established in 1995 and received 4 lb N/1000 ft2/yr, is irrigated as needed and receives 'traffic'. They are mowed at two inches. The third trial was established in the fall of 1995 and was a low-maintenance study that received 1 lb of N/1000 ft2/yr in September and is non-irrigated. The objective of the high-maintenance, irrigated study was to investigate cultivar performance under a cultural regime similar to that used on irrigated home lawns in Iowa. The objective of the second study was to observe cultivar response under conditions similar to those found in irrigated lawns and sports fields that receive substantial traffic wear. The objective of the third study was to evaluate cultivars under conditions similar to those maintained in a park or school ground.
The values listed under each month in Tables 1 and 2 are the averages of visual quality ratings made on three replicated plots for the three studies. 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. The first cultivar received the highest average rating for the entire 1998 season. The cultivars are listed in descending order of average quality.
Data for genetic color (Gcol), spring greenup (Grn), and leaf texture (Leaf) also are included for the high-maintenance, irrigated and for the low-maintenance trials. Genetic color was rated using a 9 to 1 scale with 9 = dark and 1 = light green. Spring greenup was estimated using a 9 to 1 scale with 9 = green and 1 = dormant turf. Leaf texture was assessed with a 9 to 1 scale with 9 = fine and 1 = coarse texture.
Data for the high-maintenance, irrigated traffic study are included in Table 3. The cultivars are listed in descending order according to wear tolerance ratings for the 1998 season. Tolerance was assessed using a 9 to 1 scale with 9 = best and 1 = worst tolerance. The first cultivar listed was the most wear tolerant cultivar. The percentage of fall ground cover (Fcov) data also are included in Table 3.
