Özet

Tea (Camellia sinensis L.), which holds strategic importance for agricultural production in the Eastern Black Sea Region, is not only a primary source of income for regional producers but also holds critical industrial value. One of the important byproducts of pyrolysis, which utilizes waste tea fibers from tea processing to produce charcoal, is wood vinegar. The aim of this study was to determine the optimum concentration of tea wood vinegar on tea seedling development as an alternative input that could contribute to reducing the use of synthetic fertilizers in fresh tea production. This study was conducted in the greenhouse of Recep Tayyip Erdoğan University in 2025 using a randomized plot design with three replications. Applications were made at 10-day intervals to two-year-old tea seedlings of the Zihni Derin variety in potted medium (peat:vermiculite ratio of 3:1). Control 1 (K1, untreated), control 2 (K2, commercial wood vinegar), and five different tea wood vinegar doses (1/500, 1/1000, 1/1500, 1/2000, and 1/2500) were compared. Significant differences were observed in the morphological and physiological characteristics of the plants as a result of the treatments. Specifically, in terms of shoot development, the highest shoot length (22.1 cm) and shoot diameter (3.3 cm) were observed at the 1/500 dose, while the highest leaf count (15.3) and lateral shoot count (3.3) were observed at the 1/1000 dose. Chlorophyll content (33.8 SPAD) was measured at the 1/2500 dose, and leaf area (14.2 cm²) was measured at the K2 treatment. It was concluded that the application of 1/1000 diluted wood vinegar may be more effective in increasing the amount of shoots to be harvested in tea compared to other doses in mitigating the negative effects on global warming by reducing soil pollution and biological activity losses caused by excessive use of synthetic fertilizers.
