The study was carried out during the period 1.10.2024-1.8.2025 at the Institute of Fruit Growing - Plovdiv. The object of the research is the local walnut cultivar Izvor 10, grafted onto a common walnut rootstock (Juglans regia L.). Variants of the experiment are: Variant I - Walnut plants grown in the field (control) and Variant II - Walnut plants grown in containers (50 l) with a peat-perlite mixture (2:1). The following indicators were reported: stem cross-section, vegetative shoot length, canopy volume and content of photosynthetic pigments in the leaves. Growing conditions have a significant impact on the growth characteristics of young walnut plants. Higher values for stem cross-section, vegetative shoot length and canopy volume were found in plants grown in containers, with differences compared to the control variant being statistically proven. Container growing had a positive impact on the content of photosynthetic pigments in the leaves of walnut plants, which in turn is a prerequisite for better photosynthesis.
