Organic and inorganic fertilizers play an important role in improving the nutritional quality of coriander plant (Coriandrum sativum L.). This study consists of 3 different fertilizer applications to coriander: Control-T0 (no fertilizer); organic fertilizer- T1 (300-600 mL/da); chemical fertilizer-T2 (2-3 L/da); vermicompost-T3 (1.5 L/da). It was conducted in three replicates in a randomized block design to evaluate the effect of different fertilizer applications on the morphological, biochemical and antioxidant potential of coriander plants. It has been observed that fertilizer applications have a significant effect on the morphological, biochemical and antioxidant properties of the plant, and especially organic fertilizer and vermicompost applications have higher phenolic and flavonoid contents (1.82, 2.14 mg GAE/g DW and 2.57, 2.46 mg QE/g DW, respectively). In the HPLC analysis, linalool was determined as the main compound and the highest concentration of 76.44% was obtained as a result of organic fertilizer application. Antioxidant potential was evaluated by DPPH radical-scavenging assay and the most effective antioxidant activity was determined from organic origin fertilizer (organic-IC50: 27.35±2.52 µg/mL, vermicompost-IC50: 29.42±2.41 µg/mL) applications.
