Effect of Different Nitrogen Doses on Quality Characteristics of Sater (Satureja hortensis L.) Plant

Satureja hortensis is an important species among the medicinal and aromatic plants used as thyme. This study was carried out in Kahramanmaras central conditions in order to determine the yield and quality characteristics of Satureja hortensis (0, 5, 10, 15, 20, 25, 30, 35, 40, 45 kg da-1) at increasing nitrogen doses. The experiment was set up in the research area of Sutcu Imam University, Faculty of Agriculture, Department of Field Crops according to the Factorial experimental design in randomized blocks with 3 replications. According to the results of essential oil analysis and macro-micro nutrients; essential oil yield was determined as 5.19-20.79 L da-1, protein ratio was determined as 11.12-22.70%. Twenty three different components were determined in the essential oil and the main components are; carvacrol was determined as 31.64-39.03%, ɣ-terpinene as 32.38-38.27%, p-cymene as 6.34-10.71%, carene as 2.90-5.60% and myrcene as 3.06-3.91%. Plant nutrients in dry herba; phosphorus was determined in the range of 2361.00-4552.00 mg kg-1, iron 107.45-222.85 mg kg-1, zinc 25.18-47.82 mg kg-1, manganese 22.16-46.92 mg kg-1, potassium 12790.00-22615.00 mg kg-1, calcium 10225.00-21235.00 mg kg-1, copper 9.15-17.73 mg kg-1, sodium 33.41-75.55 mg kg-1 and nitrogen was determined in the range of 2.21-4.50%.
