Foliar Application of Some Macronutrients and Micronutrients Improves Yield and Fruit Quality of Highbush Blueberry (Vaccinium corymbosum L.)

Foliar fertilization makes it possible to quickly provide plants with essential nutrients, mainly micronutrients, which can significantly improve the quality of yields. The aim this study was evaluate effect foliar fertilizers containing calcium and microelements on yielding fruit highbush blueberry (Vaccinium corymbosum L.). A two-year carried out in western Poland an experimental production plantation. During growing season bushes were treated several times following fertilizers: Armurox, BioCal, Stymjod. experiment assessed bush growth vigor, yield, characteristics, sugar, organic acid, health-promoting substance content. It found that as a result fertilizing fertilizers, leaf blade area plant yield increased significantly. fruits collected from those characterized by higher mass, firmness, TSS This also applies after storage. had no significant content chlorophyll b leaves northern blueberry, coloration, sugars, ascorbic citric acids, phenolic compounds them.
