영문 초록

To select the proper fertilizer for the production of Okro tea, four types of fertilization (Urea-Fused phosphate-Potassium chlaride, Urea-Fused phosphate-Potassium sulfate, Ammonium sulfate-Fused phosphate-Potassium chloride, Ammonium sulfate-Fused phosphate-Potassium sulfate) were applied. The soil fertility of the experimental field was higher in organic matter (47.9g kg-1) and available phosphate(1.065mg kg-1), but lower in pH(5.4) compared to the common field. The growth and yield were more excellent in the second treatment (Urea-Fused phosphate-Potassium sulfate) compared with other treatments. The amount of chemical components such as total nitrogen, total amino acid, chlorophyll and vitamin C were higher in the second treatment compared with other treatments. Sixteen kinds of free amino acid including theanine as a good taste component of Okro tea were isolated and measured by HPLC. Theanine content, the second treatment. was the highest value of 120~290mg/100g compared to other treatment. `rhe tea appearance and interal factors were better in the second treatment than in other treatments. Consequently, Urea-Fused phosphate-Potassium sulfate is considered to be the best kind of fertilizers for both quality and yield.
