Effect of mycorrhization treatment on the yield and quality of highbush blueberries in conditions of replantation

In the years 2010 - 2016, the effect of mycorrhization treatment in the cultivation of the Highbush blueberry (Vaccinium corymbosum L. "Bluecrop") on the yield and fruit quality was examined. The bushes were growing in replanted soil (after 30 years of blueberry cultivation) and in so-called virgin soil - not previously used for orchards. The mycorrhizal vaccine was used one-time during the growing season at the point when the plants were planted permanently. It was shown that the mycorrhizal treatment had a positive effect on the yield of the Highbush bluebeny bushes and on improving the quality of the fruit, in particular under stress conditions for the plants (replanted soil). The yield and quality of the blueberry fruit growing in the soil after the previous 30-year-old cultivation of this species has usually not deteriorated.
