Abstract
The influence of fertilizer on protein content of brown rice was investigated on the samples in high yield (average yield of brown rice: 694kg/10a) at farmers' field. With respect to amount of fertilized nitrogen, basal dressing and top dressing at Young panicle formation stage did not increased the protein content. However, the amount of top dressing after heading stage, both top dressings at young panicle formation stage and heading stage, and total dressing showed positive correlations with the protein content at the 1% level of probability. On the other hand, phosphorus and potassium did not affected the protein content.
