| This study was conducted to investigate the effect of compound fertilizer contained slow release nitrogen such as isobutylidene diurea(IBDU) and methylene urea(MU) on kentucky bluegrasss and the change of nitrogen in the root zone after supplying these at AM turfgrass research institute with soil analysis, chlorophyll content index, leaf area index and dry weight during 6 months from July to December in 2007 year. Fertilizer treatments were designed as following; non-fertilizer(NF), straight fertilizer(CF), methylene urea(MU), isobutylidene diurea(IBDU). The every treatments were arranged a randomized complete block with three replications. Results obtained were summarized as follows: As relative to time after N fertilizers application, ammonium and nitrate in soil were increased, but T-N was decrease. The change of ratio of available Nand T-N by elapsed time after fertilizing was decreased in CF from 30days but increased until 45days. Compared with NF, the turf color index in CF, MU and IBDU was increased 1.5%, 2.5% and 2.3%, respectively, the chlorophyll content 16%, 25% and 26%, the dry weight 31%, 62% and 46% and shoot number 104%, 185% and 148%. The chlorophyll content index of MU and IBDU was increased 7.5% and 8.8% than that of CF, shoot number 40% and 22%, and dry weight 24% and 12% but turf color index was similar to that of CF. These results showed that the MU and IBDU application was supplied nitrogen for a long time in root zone by increasing an available nitrogen, and so promote turf grass growth such as chlorophyll content and shoot number in kentucky bluegrass. |
