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

The young trees were grown at a spacing of 25 cm × 1.0 m on a podzolic soil. The study focused on the differences in diameter and height of the maiden stock, the branch number, lateral shoots in the crown and their length, among treatments with various bioproducts applied to the maidens once or twice, such as granulated manure, Micosat, Humus UP （humus cultivated）, Humus Active ＋ Aktywit PM （positive microorganisms）, BioFeed Amin, BioFeed Quality, Tytanit and Vinassa. The control maidens were not fertilized at all, or fertilized with NPK （nitrogen, potassium, phosphorus）. The first time when these products were applied in the nursery was mid-May, and the second time was one month later. Repeating the application of humic preparations （vermiculites） and a formulation containing mycorrhizal fungi （Micosat） gave better results than applying them only once, but in the case of BF Quality and the preparation Tytanit treating the plants for the second time did not increase their growth vigour compared to the plants treated only once. And the effectiveness of the biopreparations was different for the treated cultivars changed.展开更多
