The aim of this study was to assess the yield and fruits quality of apple produced in ecological system. In 2022 the influence of different fertilizers on yield and fruits quality at three apple cultivars was carried out. The trees were planted in a spacing of 3 x 2 m, according to the following experimental scheme: Factor A - cultivar, with three graduation (a1 - 'Romus 3’, a2 - 'Idared’ and a3 - 'Golden delicious’); Factor B - fertilization variant, with four graduations (b1 - Biohumus - 0.5 L/tree, soil application + Macys BC 28 - 2 L/ha, foliar application + Cifamin BK - 1 L/ha, foliar application; b2 - Biohumus - 0.7 L/tree, soil application + Macys BC 28 - 2 L/ha, foliar application + Cifamin BK - 1 L/ha, foliar application; b3 - Biohumus - 0.9 L/tree, soil application + Macys BC 28 - 2 L/ha, foliar application + Cifamin BK - 1 L/ha, foliar application; b4 - 'Unfertilized’). As results of the investigations we found that the highest fruit yield and fruits quality was obtained at 'Idared’ (28.66 kg/tree, respectively 215.66 g) cultivar in fertilization variant 3.
