We examined the influence on yield and the quality of tea when the amount of fertilizer was reduced by half for six years. In first crop of tea, the yield of plucked new shoot has decreased immediately after fertilizer reduction. Among the crude tea elements, the content of the amino acid decreases at the examination latter term. Among the crude tea qualities, the taste became a little inferior tendency. In second crop of tea, the yield of plucked new shoot decreased immediately after beginning of the exanimation. But after year fourth, the influence was lost. In the crude tea element, the content of the amino acid has decreased. And it was a tendency that the content of tannin increases a little. The taste was a little inferior tendency in the crude tea quality.
