Summary: The article investigates the influence of traditional mineral fertilizers (N60 Р60К60) and biofertilizers on the indicators of preservation, growth, individual productivity and yield of apple fruits in 2022 – 2024 in the intensive semi-dwarf apple orchard of Vinnytsia National Agrarian University. The largest number of planted apple fruits on one tree was found when fertilizing with the Bionorma nitrogen preparation – 330 pieces. This was 23.9% more than in the control variant without fertilizer application, where 251 fruits were planted. Also, many fruits were formed on the variant with complex mineral fertilizer N60 Р60К60 – 317 fruits, which was 20.8% more than on the control. The July and August fruit fall was insignificant compared to June. In particular, 0.3-1.1% of all laid fruits were lost in July. The greatest losses were observed on the control variant without fertilizers and with the application of mineral nitrogen N60, and the smallest – on the variants with the application of biofertilizers Bionorma nitrogen and Bionorma garden. The most intensive growth in fruit diameter was observed on the variants with the application of biofertilizer Bionorma phosphorus and on the control without fertilizers – 48.3% each, from 3.0 to 5.8 cm. A strong negative correlation was found between the number of apple fruits on the tree and their diameter (r = – 0.8029). The largest apple harvest from one tree was established on the variant of applying complex mineral fertilizer N60 Р60К60 – 23.90 kg, which amounted to 39.617 t/ha.
