영문 초록

The study was aimed with establishing an efficient management system for nutrition and soil water in tea plantation of Jeju, Korea. Effect of irrigation conditions with different soil water pressures (control, 10-30, 30-50, and 50-100 kPa) on tea shoot growth and quality and soil properities was evaluated. Tea shoot yield was higher at irrigated treatments than at control, however there was little difference among irrigated treatments. Total free amino acids and theanine contents at irrigation were higher, with the tendency of increase as irrigation was delayed, than those of control. On the contrary, fiber showed opposite tendency. Irrigation increased the content of K, Mg, Na, Zn, Cu, and Fe of inorganic elements compared with control, whereas decreased Mn content. NO3-N contents of soil and soil solution were affected by irrigation conditions.
