In recent years, due to salutary effects of its fruits, the black chokeberry [Aronia melanocarpa (Michx.) Elliott] has gained popularity in Serbia and it has been grown on a variety of soil types. A three-year study was conducted in order to assess the establishment and early growth of the black chokeberry on an acid soil and a calcareous soil. Experimental plots were established in the spring of 2009. Young plants on their own rootstocks, which originated from the same source, were planted. The plants were grown as shrubs and they received conventional mineral and organic fertilizers. The following parameters were measured in five replications in the second and third years of the experiment: number of shoots, height and width of the shrub, and fruit yield. In the third growing season, the contents of following elements: P, K, Ca, Mg, Fe, Mn, Zn, Cu were analyzed in black chokeberry leaves and fruits.
