To establish the optimum nitrogen level for rice planting after Italian ryegrass cultivation, one experiment was conducted on a normal paddy soil (Jeonbug series soil taxonomy) with six different nitrogen treatments for two years from 2009 to 2010. The treatments were including no nitrogen fertilization (Free N), 50%-Basal N, 75%-Basal N, 100%-Basal N, 150%-Basal N and 100% of basal fertilization with 30 kg N ha<sup>-1</sup> (100%+ N30-Basal N) for decomposing of Italian ryegrass stubble. The highest rice yields were 8,420 obtained by 100%-Basal N. 150%-Basal N and 100%+N30-Basal N produced a rice yield of 8,190 kg ha<sup>-1</sup>. Those of 50%-Basal N and Free N were produced 8,020 and 7,370 kg ha<sup>-1</sup>, respectively. The correlation between rice yield and nitrogen treatment showed a quadratic relationship in high significant. According to this regression, the highest level of nitrogen treatment was 73 kg ha<sup>-1</sup> and the highest rice yield was 8,405 kg ha<sup>-1</sup>. Nitrogen uptake rates were relatively higher with lower amounts of nitrogen fertilizer treated.
