The fertilizing system combined with 3 kinds of coated urea was examined in order to maintain the tea yield and quality by the 35kg/10a reduction of fertilizer nitrogen amount. In the test period 6 years, there was no difference between the ordinary fertilization and this experimental one in the yield of first and second crop of tea. And the content of total nitrogen and free amino acid in the plucked new shoot(crude tea) was also equivalent. This fertilization system is effective both to maintain the tea yield and quality and to reduce the environmental loading.
