А pot experiment was conducted to investigate the impact of different fertilizer rates on growth characteristics and nutritional status of plants from Redhaven cultivar, grafted on GF677 (P. amygdalus x P. persica) rootstock and grown in containers. Variants of the experiment were: Variant I - Control (non-fertilizer), Variant II - N1P0.25K0.5Мg0.1, Variant III -N2P0.5K1Мg0.2 and Variant IV -N3.2P0.8K1.6Мg0.32. The results show that, at the three fertilized variants are obtained plants with a height of 164 to 177.26 cm and a stem diameter of 12.10 to 12.65 mm. The highest average values for stem diameter (12.65 mm) were found in low-fertilized plants. The control plants reached average values of 59.13 cm in height and 5.86 mm in stem diameter and in comparison to all fertilized variants the differences were statistically proven. The results obtained show that the fertilization influenced the content of N, P, K, Ca and Mg. It is concluded that fertilization with all three fertilizer rates (N1P0.25K0.5Мg0.1; N2P0.5K1Мg0.2; N3.2P0.8K1.6Мg0.32) are suitable for the container production of peach planting material for establishing fruit orchards.
