Rice quality, yield, and nitrogen use efficiency can be improved through nitrogen fertilizer strategy, such as the rate and the timing of application. The objective of this study was to find the suitable way of nitrogen application for improving the rice yield, quality , and NUE under the condition of the high yield. The two-year trail was run from 2003 to 2004 at the field experimental farm. Using Wuxiangjing14, Changyou1, Fengyouzhangzhan and Kyou818 and planted with a total applied nitrogen a...
