At the Fruit Growing Institute in Plovdiv, Bulgaria through pot experiment was made an attempt to establish the impact of different fertilizer rates on growth characteristics and nutritional status of plants from 'Bigarreau Burlat’ cultivar, grafted on MaxMa14 (P. mahaleb x P. avium) rootstock and grown in containers. The following variants were tested: Variant I - Control (non-fertilizer), Variant II - N₁P_0,25K_0,5Мg_0.1, Variant III - N₂P_0,5K₁Мg_0.2 and Variant IV - N_3.2P_0.8K_1.6Мg_0.32. The results show that, at the three fertilized variants are obtained plants with a height of 129 to 148 cm and a stem diameter of 11.3 to 12.8 mm, as with increasing the fertilizer rate increases plant height. It was found that plants of the control variant are characterized by lower average height values (68 cm) and stem diameter (8.2 mm) compared to the fertilized plants, the differences being statistically significant. It is concluded that fertilization with Kristalon by YARA in fertilizer rates N₁P_0,25K_0,5Мg_0.1; N₂P_0,5K₁Мg_0.2; N_3.2P_0.8K_1.6Мg_0.32 results in the production of cherry planting material suitable for fruit orchards.
