영문 초록

This study aimed to evaluate the effect of fertigation rates on shoot growth and quality in young tea (Camellia sinensis L.) plants growing in pots under plastic house and adult tea plants growing in open field. Fertigation rates were adjusted at 100, 75, 50, and 25% of recommended application by common practice for 1st year and 60, 45, 30, and 15% for 2nd and 3rd years. There was no difference in tree height and canopy width of young trees with different fertigation rates, however higher occurrence of physiological disorder was observed in higher rates than 30%. Soil pH and Ca and Mg content had a tendency of decrease as fertigation rate increased, which was contrary to EC. The number of new shoots and yield of adult trees with fertigation were higher than those of control, however there was no increase in shoot length and the number of leaves per shoot. Similar tendency was observed in quality of tea leaves; T-N, amino acids, and theanine contents were higher than those of control, however catechin, caffeine, tannin, fiber, and vit. C contents were not affected by fertigation. Na, Zn, Cu, and Fe contents were lower in leaves of control than those of fertigation, however Ca, K, Mg, and Mn contents were not affected by treatments. The results indicated that 30% fertigation rate might be applied to tea cultivation as an efficient method for fertilizer application.
