The paper presents the results of an experiment that involved evaluation of the effects of application of new types of fertilizers and employment of new ways of fertilization in the production of hazelnut planting material. The experiment was set up on eutric cambisol soil type ameliorated with 100 t/ha of manure. Fertilizer was not applied in the control variant, whereas the NPK (15:15:15) variant with 600 t/ha was treated as the standard variant. Other variants included application of slow acting fertilizers (600 t/ha dosage of 4-6 months activity) and liquid fertilizers (11:14:11, by pouring them by 0.5% solution). All applied mineral fertilizers are combined with a new type of organic fertilizer, which actually includes processed poultry manure obtained by larvae of the domestic fly (Musca domestica L.). This fertilizer (OFERT) contains a very high percentage of phosphorus (5.56%), substantial part of it being in accessible form (560 mg/100 g). Two methods were applied in the plant treatment thus eight variants of the experiment involved all forms of fertilization within two variants: at planting and upon planting.
