영문 초록

A field experiment was conducted to evaluate effect by split-application method of slow-release fertilizer on the tea plant. The yield of the 1st harvested tea leaves had increased 3% in the slow-release fertilizer(two time split manuring) compared with the traditional manuring(four time split manuring), and that of the slow-release fertilizer to one time split manuring was decreased 14±3%. In case of the 1st harvested leave, the contents of chemical components related to quality such as total nitrogen, total amino acid, caffeine, chlorophyll, vitamin C, fatty acid and theanine were somewhat higher in the slow-release fertilizer(two time split manuring) than those of the traditional manuring, but that of tannin was low. The one time split manuring of slow-release fertilizer had a contrary tendency with two time split manuring treatment. In scoring test, appearance and quality of green tea were more excellence in the two time split maunring compared with one time split manuring of slow-release fertilizer and with the traditional manuring (four time split manuring). Yield of tea was increased, quality of tea was improved and loss of N, P, K was decreased with use of slow-release fertilizer.
