An investigation on nutritional status of Tea (Camellia sinensis L.) grown in Eastern Black Sea Region of Turkey

Abstract

This investigation was carried out to determine the nutritional status of tea (Camellia sinensis L.) in the Eastern Black Sea Region of Turkey. For this purpose 35 soil samples were taken from 0-40 cm depth different area and 35 tea leaf samples were collected from different plantation. pH, organic matter, texture, N, P, K, Ca, Mg, Fe, Cu, Zn and Mn contents were determined on these soil samples. N, P, K, Ca, Mg, Fe, Cu, Zn and Mn contents were determined in leaf samples. According to the results, soils were Clay (C) and Clay Loam (CL) texture, generally; strong and medium acid reactions and high organic matter content; N, P, K, Ca, Mg, Fe, Cu, Zn and Mn contents of soils were determined as 0.12-0.37%; 3.80-20.26 mg kg-1; 87-325 mg kg-1; 980-3460 mg kg-1; 80-390 mg kg-1; 10. 42-44.79 mg kg-1; 0.73-16.76 mg kg-1; 0.69-18.72 mg kg-1 and 14.80-82.42 mg kg-1, respectively. N, P, K, Ca, Mg, Fe, Cu, Zn and Mn contents of leaf samples were determined as 3.80-9.87%; 0.06-0.40%; 1.46-2.68%; 0.33-0.86%; 0.15-0.38%; 540-1070 mg kg-1; 10-26 mg kg-1; 30-56 mg kg-1 and 111-465 mg kg-1, respectively. © 2006 Asian Network for Scientific Information.
