The experiment evaluated the possibility of ecological fruit production of two apricot cultivars. Trees grafted on Myrobalan seedlings were planted in the spring of 2004 in the Experimental Ecological Orchard in Nowy Dwór-Parcela near Skierniewice (central Poland). The experiment was conducted in accordance with the principles of organic fruit-growing. Under organic orchard conditions, the trees of the cultivar ‘Wczesna z Morden’ grew more strongly than the trees of the cultivar ‘Harcot’. Fruit yields varied over the research years; however, the total yields for the period 2008–2014 were low. The ‘Wczesna z Morden’ trees were more productive. Spring frosts and windy and rainy weather during flowering had an adverse effect on the setting of fruit and apricot yield. Fruits of the cultivar ‘Harcot’ had a larger mass; however, a higher proportion of fruit damaged by the brown (Monilinia) rot of stone-fruit trees was observed in the crop.
