The experiment was performedin strawberry plantation with the aim of examining the effect of foliar application of calcium and potassium on fruit quality, i.e. the fruit size and chemical fruit properties. In addition, the aim was to determine how the treatments affected the ability to store fruits. The experiment analyzed the influence of: 1) calcium carbonate (0.5%); 2) calcium nitrate (0.5%); 3) WAKE-up® Liquid fertilizers (1%); 4) potassium nitrate (0.5%); 5) calcium carbonate (0.5%) + WAKE-up® Liquid (1%); 6) calcium carbonate (0.5%) + potassium nitrate (0.5%); 7) calcium nitrate (0.5%) + WAKE -up® Liquid (1%); 8) calcium nitrate (0.5%) + potassium nitrate (0.5%). The investigation also included control treatment with a standard fertilization program. The treatments were effective in preserving the quality of the fruit after cold storage and increasing the calcium content in the leaf. Also, the application of WAKE-up® Liquid showed an effect on increasing the weight, height and diameter of the fruit, and in combination with calcium nitrate had affect on fruit firmness after harvest. The treatments had impact on the contents of soluble solids and total acids, while had no affect firmness of the fruit after cold storage.
