Effects of Fertilization on Vegetative Growth, Yield and Fruit Quality of Black Chokeberry (Aronia melanocarpa Elliot)

Black chokeberry (Aronia melanocarpa Elliot) is a deciduous fruit shrub from Rosaceae family that does not have a long cultivating tradition in Bosnia and Herzegovina. Therefore, the aim of this research was to determine the effect of variety, quantity and combination of fertilizers on characteristics of vegetative growth, yield and fruit quality of black chokeberry of Nero cultivar, in agro - ecological conditions of the Una – Sana Canton (Bosnia and Herzegovina). The experimental site fertilized with the combination of mineral and organic nitrate fertilizers gave the best results in morphometric characteristics of fruit, yield and vegetative characteristics of growth. Fruits from the control site had the highest values when it comes to the most of the following characteristics: dry matter content, ash, total acidity, vitamin C and total phenolic content. Statistical analyses showed that factors of quantity and the manner of fertilization influence significantly most of examined parameters in this research (P ≤ 0.05).
