This study was carried out to clarify the relationship between nitrogen fertilizer and the free amino acid composition of brown rice. Glutamic acid was the most abundant among the free amino acids tested in brown rice. Glutamic acid, aspartic acid, asparagine, arginine, alanine and glutamine were the six major amino acids contained in brown rice. The amounts of free amino acids extracted from brown rice showed a significant negative correlation with the total nitrogen content of brown rice. Furthermore, the total amount of free amino acids, glutamic acid, aspartic acid, asparagine, glutamine and alanine contents of rice grains produced without nitrogen fertilizer applications were higher than those of rice grains produced with nitrogen fertilizer applications. It was observed that the total amount of free amino acids and glutamine content of brown rice tended to increase with the decrease in 1000-grain weight
