Abstract
The object of this experiment was to suggest the optimum N fertilization level in Kentucky bluegrass pasture fer turf'of school ground. The field trials were conducted from 2001 to 2003 at Chungnam National University in order to evaluate the dry matter yield and quality on the N levels(100, 150 and 200kg/ha). With increasing the N level, the average DM yield for 2 years in Kentucky bluegrass pasture significantly increased. The average total DM yields was 6,317, 8,495 and 10,361 kg/ha at N 100, 150 and 200 kg/ha level(p<0.05), respectively. CP content and DMD were significantly increased(p<0.05), whereas fibrous constituents were not detected obvious tendency, but CPDM and DDM yields were significantly increased with increasing the N levels for 2 years(p<0.05). Based on the results, considering the total DM yield and quality of herbages which incidentally produced from Kentucky bluegrass pasture in school ground, it can be suggested that the suitable application N level was 200 kg/ha.
