The aim of the present study was to investigate the influence of different bioferilizers on the yield, fruit quality and storage properties of ‘Sampion’ apples. Foliar sprays of AlgaminoPlant and Goëmar BM 86 were conducted once or three times, whereas HumiPlant was used for ground spraying. An assessment of the total yield, mean weight of fruit, fruit firmness (FF), soluble solids content (SSC), titratable acidity (TA) was performed at harvest as well as after the storage period (150 days). The obtained data indicate an overall beneficial effect on the yield and its quality. Foliar sprays increased the total yield of the investigated apple trees. Goëmar BM 86 and HumiPlant significantly enhanced the mean fruit weight as compared to the control. Apples treated with Goëmar BM 86 showed the highest fruit firmness and soluble solids content, however titratable acidity was at the lowest level. Treated apples revealed a lower organic acids reduction after the storage.
