영문 초록

This study was carried out to improve the rice grain quality of Ilpum cultivar, especially to reduce the chalky rice rate by controlling top dressing of nitrogen application ratio at the tillering and panicle initiation stage. In the rice plant growth, the number of tiller and leaf area index of maximum tillering stage were influenced by basal dressing and top dressing at tillering stage; however those of heading stage were mainly influenced by top dressing at panicle initiation stage. In yield and yield components, they were influence by the top dressing at panicle initiation stage and the rice yield was increased by percentage of the top dressing. The protein content of rice grain was increased as the rate of top dressing at panicle initiation stage was increased. The rate of chalky and damaged rice was remarkably increased as the top dressing ratio was increased, resulting in reducing the rate of head rice rate. As the results, the characteristics of milling and rice quality was improved when the amount of top dress was reduced as 50% at the panicle initiation stage, and the yield of head rice also increased.
