Changes in Essential Oil Content Tea Seed and Leaves according to the Elevation and Soil Characteristics

Versatile evaluation of agricultural products an important issue of increasing importance with each passing day. Evaluating of other spin-off products except green tea, such as tea seed, tea waste, etc.., that can be increased revenues from a hand unit area, and on the other hand environmental problems cause waste materials can be removed to minimize or may eliminated. The aim of this study was to determine oil content of tea seeds and leaves according to elevation and soil characteristics. According to results, it was not determined essential oil from tea seeds even though trace amounts. According to levation, tea seed oil ratio was different in statistically significant levels. The highest amount of oil ratio was determined 24.30% in the second elevation (asl 800m), while the lowest amount of oil content was determined 19.85% in the third altitude (asl, 1100 m). Negative relationship were determined among the soil characterists of clay, silt, pH, nitrogen content and elevations. According to elevation, essential oil content in dried tea leaves in the room conditions first increased and then decreased again. The highest amount of oil ratio in tea leaveswas determined in the second elevation (asl 800m), while the lowest amount of oil content tea leaves was determined in the third altitude (asl, 1100 m). It was determined strongly negative relationships between clay and oil content in dried tea leaves in the room conditions.
