Russian. Raspberry (Rubus idaeus L.) is a traditional berry crop in Russia. Cultivation of seedlings of promising raspberry varieties in container technology allows extending the period of planting material, as well as to plant in the ground throughout the vegetation period. In order to obtain high-quality planting material, it is necessary to select fertilizers that will have a positive effect on the parameters of the above-ground and underground parts of the seedlings during container cultivation. For this reason, we used a new generation of fertilizers in the experiment. According to the results of the research, it was found that the number of shoots in the varieties when using different fertilizers do not differ greatly. A significant effect of variety features, fertilizers and interaction of factors on the volume of the root system has been proved. The total length of shoots is significantly influenced by varietal characteristics. The maximum root system volume (640 ml) and shoot length (136,8 cm) were established in the variety Vajolet. In Georgia the shoot length (90,3 cm) and root volume (399 ml) were minimal. Osmocote fertilizer (766 ml) had the best effect on root system volume. Fertilizer for fruit crops was the least effective for root system development (374 mm). Vajolet and Przehyba with Osmocote had the highest root volume (902 ml and 827 ml). The worst root system development in Georgia with fruit-berry fertilizer (190 ml) and OMU (298 ml), in Przehyba with OMU (303 ml).
