The effect of shading on shoot yield and T-N(Total-Nitrogen), T.A.A(Total Amino Acids), tannin, free amino acids and free sugars content of tea shoot was examined under different shade periods. The results are summarized as follow. The soil of experimental field was higher in organic matter(40.3g/kg), available phosphate(1,149mg/kg) and C.E.C(18.9cmol⁺/kg) compared to the general field, but lower in pH(5.1) compared to the general field. The yield of tea leaves was increased with the passage of shade treatment periods. The yield of tea leaves was the lowest in the 14 days shading as 163kg/10a, while the yield was the highest in the 27 days shading as 315kg/10a. The contents of total nitrogen, total amino acid was decreased with the passage of shade treatment period, while the content of tannin, caffeine and vit. C was increased from 21 days to 26 days shading, but decreased from 27 days shading. Most of free amino acid contents such as aspartic acid, theanine, serine, glutamic acid and arginine was decreased with the passage of shade treatment periods : however, the content of valine, isoleucine and leucine was increased. The content of free sugar was the lowest in the 16 days shading as 690.0mg/100g while the content of free sugar was the highest in the 24 days as 885.0mg/100g. Consequently, 22~23 days shade treatment periods is considered to be the best shade periods in terms of high quality as well as crop yield.
