In 2000, at the Experimental Scientific Station of the Institute of Botany in peat soil of transitional type 11 cultivars of large cranberry (Oxycoccus macrocarpus (Aiton) Pursh) were planted; in 2001 they were mulched with vermicompost. The impact of this fertiliser depended upon peculiarities of a cultivar. Some cultivars positively reacted to the application of vermicompost and developed longer and slightly thicker fruit branches and annual vegetative shoots with considerably higher number of leaves. Yet other cultivars of Oxycoccus macrocarpus negatively reacted to the impact of ver-micompost, i.e., developed shorter fruit branches and annual vegetative shoots.
