Abstract
Improper use of chemical fertilizers in agricultural production, especially in hydroponic cultivation, not only fails to increase crop yield but also reduces the quality characteristics of the fruit, ultimately leading to increased water consumption. Therefore, reducing the nutrient solution is essential in greenhouse production systems. In this study, the quantitative and qualitative characteristics of the Albion strawberry cultivar were evaluated under deficit fertigation conditions at three nutrient solution levels (100, 140 and 180 ml) in 19 cm pots containing 1:1 cocopeat and perlite substrate. According to the results, low solubility treatment significantly affected plant height and width, number of leaves, fruit shape, fruit pH, soluble solids, fruit flavor, titratable acidity and firmness of fruit texture. Most morphological traits measured decreased under deficit fertigation stress. The highest total yield, soluble solids, and fruit flavor were observed in 140 ml deficit fertigation treatment, whereas the highest titratable acidity and pH of fruit juice were observed in the control treatment. These findings suggest that moderate deficit fertigation can be used as a reliable method to enhance the quality of greenhouse products.
