The aim of the present study was to determine the influence of mineral and peat soil condition on the growth, yield and nutrient uptake of some half-highbush blueberry cultivars. The peat soil experimental site was located in a harvested (milled) peat field. Four half-highbush blueberry ( Vaccinium spp.) cultivars (five- and six-year-old plants) were used in the experiment: "Aino", "Alvar", "Arne", and "Northblue". Environmental conditions exercised a considerable influence on biological processes of half-highbush blueberry, at the same time, a genotype-based variation was observed. Cultivar "Northblue" had a higher yield in mineral soil and "Aino" had the highest yield in peat soil considering the average of two years. The peat soil condition in the harvested peat field provided a better supply of nutrients for blueberry bushes compared to mineral soil and this, in its turn, secured better growth and a higher yield of blueberry bushes.
