  • Effect of rice bran applied alone or in combination with chemical fertilizer on growth and edible quality of rice was investigated. The experiment consisted of 11 treatments: 3 levels of rice bran (RB) (500, 250 and 100kg $10a^{-1}$), 100 and 50% recommended fertilizer (RF) combined with above-mentioned 3 levels of RB, and 100 and 50% RF only. The rice brans were applied at 10 days before rice transplanting. Results showed that plant height 30 days after transplanting was significantly higher at 100% RF treatment than the RB treatments. However, plant height during heading stage was not significantly different between the 100% RF and the RB treatments. At higher RB treatments, ripened grain decreased, while panicle number and plant height increased. In the case of rice yield, 50% RF + RBtreatments exhibited similar or slightly higher yield than 100% RF. These results suggested that the recommended fertilizer can be reduced by 50% in case of applying RB. In terms of nutritional quality, protein content on rice grain increased at higher RB treatment, while amylose content at 50% RF + RB treatments ($17.3{\sim}17.8%$) decreased compared to that of RF ($17.9{\sim}18.1%$). Results showed significant effects of RB application on rice growth and quality.
