Determination of quality parameters of blueberies grown in different growing media under greenhouse

The aim of this study was to determine the yield and quality parameters of 10 different northern highbush blueberry varieties in 3 different growing media. In the study, 2-year-old potted plants of Bluegrop, Bluegold, Bluejay, Chandler, Darrow, Duke, Jubilee, Patriot, Brigitta and Elliott blueberry varieties were planted in different media under greenhouse in pots. Morphological and pomological characteristics of the plants were observed. Yield, pH, total soluble solids (TSS), titratable acidity (%) and some berry parameters were determined. In the study, the average plant height varied between 60.0 cm and 161.3 cm. The fruit yield per plant were obtained as 115,6 g in growing media-1 (GM-1) and 784,7 g in GM-2 depending on the growing media characteristics. The lowest berry weight (0.68 g) was determined in GM-1 and the highest berry weight (2.27) was determined in GM-3. Within the scope of the study, the pH values of the berry samples varied between 2.55 and 3.29, the total soluble solid (TTS%) varied between 7.0% (GM-3) and 12.5% (GM-2), and the titratable acidity (TA) varied between 0.97% (GM-3) and 1.69% (GM-1). Considering the yield and quality parameters obtained in the study, it was seen that the organic media evaluated as GM 2 gave the best results. The differences that emerged depending on the varieties were evaluated in relation to the variety characteristics.
