Abstract
Improper use of chemical fertilizers in agricultural production, especially in hydroponic cultivation, not only does not increase crop yield, but also reduces the quality characteristics of the fruit, which in turn leads to high water consumption. Therefore, it is necessary to reduce the amount of nutrient solution in greenhouse production systems. In this study, some quantitative and qualitative characteristics of albion strawberry cultivar in deficit fertigation conditions with three levels (100, 140 and 180 ml) in pots with a diameter of 19 cm and a combination of cocopeat and perlite culture medium With a ratio of 1:1, was examined. According to the results, low solubility treatment on traits such as plant height and width, number of leaves, fruit shape, fruit pH, soluble solids, fruit flavor, titratable acidity and firmness of fruit texture showed a significant difference. The majority of morphological traits measured decreased under deficit fertigation stress. The highest total yield, soluble solids, fruit flavor were observed in 140 ml deficit fertigation treatment and also the highest titratable acidity and pH of fruit juice were observed in the control treatment. According to this research, deficit fertigation can be used as a reliable method to increase the quality of greenhouse products.
