| Abstract/Contents: | Presents a study to "evaluate management practices for tall fescue - Kentucky bluegrass turf. This study was modified in an attempt to determine why the tall fescue was eliminated from the turf on the football field." Results include that "there was no clear cut differences among the nitrogen levels in the amount of bluegrass or tall fescue in the turf during the first growing season. It was believed that residual nitrogen from the application at establishment was sufficient to mask differences that might have occured. By 1963, the second growing season, differences among nitrogen levels in the amount of tall fescue and bluegrass present in the turf were evident. Plots treated with either the 2 or 4 pound rate of nitrogen contained more bluegrass and less tall fescue than plots receiving no nitrogen...As nitrogen fertility was increased the bluegrass portion of the sod increased as the tall fescue component decreased...The number of shoots of Kentucky bluegrass and tall fescue increased as the mowing height was decreased from 3 to 2 inches. The increase was greater if either 4 or 8 pounds of nitrogen were applied than if no nitrogen was used." Presents a study to "examine some of the management and temperature factors which affect the winter injury of turfgrasses." Results include that "the temperature regime of this study proved to be too severe for the bluegrass-tall fescue mixture, and resulted in severe injury. The tall fescue was essentially killed by treatment A, and therefore was not statistically analyzed...Even though the bluegrass was more resistant to the cold treatment than the tall fescue, it was completely killed by treatment C. In 1966 cold treatments were modified. Since it was believed that severe injury in the 1965 study may have resulted from abrupt temperature change, temperatures were raised and lowered at a rate of one and one-quarter degrees per hour for this study...The temperature conditions of this study were found to have no differential effect on the bluegrass, since neither the bluegrass crowns nor shoots changed among cold treatments at any fertility level...Cutting height was found to affect both shoots and crowns of tall fescue and bluegrass at the 4 or 8 pound rate of nitrogen...Bluegrass shoots and crowns were injured more at the three-inch than at the two-inch cutting height...On tall fescue, the height of cut had the opposite effect than on bluegrass...Tall fescue was reduced at all three fertility levels...The bluegrass increased in percent composition after treatment at all three levels." Concludes that "a turfgrass consisting of a mixture of tall fescue and Kentucky bluegrass will gradually change to bluegrass when highly managed in a climate similar to that of Central Ohio. The increase in bluegrass and decrease in tall fescue results, at least in part, from differential winter injury to the two species. To maintain a bluegrass-tall fescue mixture with a minimum shift to bluegrass, no more than 4 pounds of nitrogen per 1000 square feet per year should be used. If the four pound rate is applied, the mowing height should be 3 inches." |
