| Abstract/Contents: | In 1980, 84 cultivars of Kentucky bluegrass were obtained from the USDA and were established in a low-maintenance Kentucky bluegrass trial at the turfgrass research area at the Iowa State University Horticulture Research Station at Ames, Iowa. Each cultivar plot was replicated three times in the study. The are received 1lb nitrogen (N)/1000 ft2 in September and received no other fertilization during the year. The area was not irrigated. In 1981, a second lot of the same 84 cultivars was obtained from the USDA and a high-maintenance trial was established on an adjacent site. This area was irrigated as needed. Both areas were uniformly mowed at a 2 in mowing height and standard weed control methods were used on both locations. In 1985, a third Kentucky bluegrass trial was established at the Horticulture Research Station in an area adjacent to the high- and low-maintenance studies. This trial was part of a new USDA study that included 80 cultivars, many of which had been included in the earlier studies. This trial received 4 lb N/1000 ft2/yr like the high-maintenance trial, but was irrigated. Weed control was performed as in the other two trials. The management regime was meant to represent the conditions that exist in many nonirrigated Kentucky bluegrass lawns in the northern region that are treated by professional lawn care companies. These lawns are generally allowed to go into dormancy in the summer and to recover in the fall. Tables are included which rank cultivars in high and low maintenance trials in 1983, give monthly quality ratings for cultivars in 1988 test and give recommendations for kentucky bluegrass cultivars for high- and low- maintenance areas. The observations from these trials have resulted in changes in Kentucky bluegrass cultivar at Iowa State University. Different cultivars are now recommended for high and low maintenances. The improved cultivars of Kentucky bluegrass are clearly the best choice when the area is to be irrigated, or when natural rainfall is sufficient to prevent summer dormancy. Under intense management regimes, the common cultivars prove to be disease prone and they will not perform as well as improved types. However, if the area is to receive a less intense management regime and is expected to go into summer dormancy during dry summers, the common cultivars will likely give more satisfactory results. Parks, school grounds, cemeteries, grassed areas along airport runways, low-maintenance home lawns, and other areas that may spend extended periods in dormancy would be best suited to the common types. |
