In this study, the use of composted hazelnut husk (CHH) as an alternative substrate for a horticultural crop, tomato (cv. Ancon), was evaluated. Before use, the CHH was separated into three different fraction sizes, 0-2 mm, 2-4 m m and 4-6.35 mm. These fractions were then mixed with soil samples, based on increasing ratios (0%, 2%, 4% and 8%, v/v) and different media were prepared. The experiment was arranged in a completely randomized design with three media, four mixture ratios with four replicates under greenhouse conditions. After a growing period of three months, plant growth and some fruit quality properties were measured. Plants were grown more successfully in 0-2 mm and 2-4 mm CHH fraction sizes and 8% mixture ratio. The effect on fruit quality of CHH fractions showed differences, however; 4% and 8% ratios of 0-2 mm CHH fraction size mixed with soil were found to be more effective on fruit quality properties. According to these results, CHH can be used for tomato growing, especially with 4% and 8% ratios of 0-2 mm and 2-4 mm CHH fraction sizes mixed with soil. For tomato plants, research of different combinations of CHH media is recommended to attain better results.
