Influence of cultivar and fertilization treatment on the yield and leaf nutrients content of apple ( Borkh.).

Fertilisation strategy can have a big impact on apple ( Borkh) yield, with considerable environmental and economic implications. This research paper presents the yield and leaf nutrients content of three apple cultivars fertilised with three treatment regimes over 2 years (2020-202) in Bosnia and Herzegovina. The specific apple cultivars investigated were: Jonagold Decosta, Red Idared and Gala Schnitzer®Schniga, each fertilised with three treatments: T (control‒without fertilization); T (300 kg ha NPK (6:18:36) + 150 kg/ha N (calcium ammonium nitrate‒CAN)) and T (foliar nutrition‒mixture organic-mineral fertilizer commercially named "FitoFert Kristal" (0.
