Thanks to the recent trends in health awareness, there has been an increasing demand for quality organic fruits. In this respect, due to their nutritional values and health benefits, the significance of strawberries has been much recognized, indicating a need for research on plant nutrition to enhance yield and product quality in organic strawberry production. Therefore, this study scrutinized the optimization of plant nutrition products readily available in the market with a license for organic agriculture on high productivity and crop quality in organic strawberry cultivation. The study investigated five different treatments, including 1) No fertilizer (control), 2) Solid vermicompost from the bottom (Ekosolfarm)+Liquid vermicompost from the top (Ekosolfarm), 3) Solid farm manure from the bottom (Biofarm)+Liquid humic-fulvic acid from the top (Botanica), 4) Solid farm manure from the bottom (Biofarm)+Liquid humic-fulvic acid from the top (Botanica)+Microbial liquid fertilizer from the top (Biosupp Ultron), 5) Solid vermicompost from the bottom (Ekosolfarm)+Liquid vermicompost from the top (Ekosolfarm)+Microbial liquid fertilizer from the top (Biosupp Ultron). In addition, plant growth parameters, yield per plant, fruit weight (g), pH, TSS, Acidity, TSS / Acid, and plant nutrient contents were studied to determine the effects of treatments on fruit yield and quality. As a result of the study, the highest total yield (242.96 g plant-1), the largest fruits (18.43 g), the lowest acidity value, the longest root, the thickest stem and the best nitrogen, phosphorus, potassium, calcium and magnesium contents in the leaves were obtained with the treatment of no. 5 that is "Solid vermicompost from the bottom (Ekosolfarm) + Liquid vermicompost (Ekosolfarm ) from the top + Microbial liquid fertilizer (Biosupp Ultron) from the top ".
