'Debreceni Botermo'/Prunus mahaleb L. maidens were fertilized with different organic fertilizers and soil amendments in an organic nursery. A mycorrhizal inoculant, Micosat, was added to the non-fertilized control and to combinations fertilized with various bioproducts. Under assessment was the effect of nutrient delivery on the growth and development of maiden fruit trees focussing on tree height, thickness of the tree trunk, the number and the length of lateral shoots in each treatment combination. It was found that the introduction of mycorrhizal fungi into the soil without fertilizer application significantly improved the growth and development of apple and sour cherry maidens. Mineral fertilizer application (NPK) combined with mycorrhizal inoculation had a negligible effect on the above features. In the presence of bioproducts such as granular manure, Humus Active + Aktywit PM, BF Amin, Vinassa and Florovit Eko, the mycorrhizal fungi were more biologically active than in the absence of these products. 展开更多
