The study was carried out during the period 2021-2022 in a young peach plantation on the territory of the Fruit-Growing Institute of Plovdiv. The object of the study was Laskava cultivar grafted on peach seedling rootstock. The aim of the present study was to investigate the effect of the organic product Bioforce on tree growth, on the content of photosynthetic pigments and major nutritional elements in the leaves and on the chemical composition of the fruits. The following variants were studied: soil nutrition with Bioforce in the form of an aqueous solution and an untreated control. The fertilized trees had higher values for the stem cross-section area (86.13 cm2 ) compared to the control ones (68.53 cm2 ). The application of Bioforce lead to an increase in the content of dry matter and sugars in the fruit flesh. The sucrose content was 5.72% in the control and 8.93% in the treated trees. Plant nutrition had an effect on the content of the major nutritional elements in the leaves, the higher values and statistically significant differences being reported for N and P. The application of Bioforce had a favourable effect on the content of photosynthetic pigments in the leaves, which is a prerequisite for the good physiological status of the peach plants.
