Treatments Comparison of Mineral and Bio Fertilizers in the Apple and Sour Cherry Organic Nursery

Maiden trees of apple cultivars ＇Topaz＇ and ＇Ariwa＇ grafted on M26 rootstock and of sour cherry cultivars ＇Debreceni Botermo and ＇Sabina＇ on mahaleb cherry （Prunus mahaleb L.） were fertilized with bioproducts such as： Fertigo-granulated manure, Micosat-microbial inoculum consisting of mycorrhizal fungi; Humus UP-an extract from vermicompost; Humus Active ＋ Aktywit PM-an extract from vermicomposts with PM （Positive Microorganism）; BioFeed Amin--a plant extract reinforced with amino acids; BioFeed Quality-a seaweed extract reinforced with humic and fulvic acids; Tytanit-titanium; Vinassa-molasses residue from yeast production; Florovit Eko-composed of many environmentally-friendly products. Control maidens were fertilized with mineral fertilizers containing mainly NPK. The maiden trees fertilized with the preparations Tytanit and Humus UP grew less vigorously and produced smaller increases in the length of lateral shoots than those fertilized with mineral fertilizers. On the other hand, bio preparations such as BF Amin, BF Quality, Micosat and Vinassa promoted tree branching and intensified the growth of lateral shoots, stimulating tree growth to a greater extent than the mineral fertilizers.
