Fertilization plays one of the most important roles among agrotechnical practices in cereal production, having direct and indirect effect on important agronomic traits. Nitrogen deficiency is one of the main factors affecting yield and quality of wheat and triticale. The research was carried out in order to assess the effect of N-fertilizer application on the yield, agromorphological traits and quality of two winter wheat and one triticale cultivars. Different types of N-fertilizers soil and foliar were applied at different growth stages, comprising 7 treatment combinations. In both wheat cultivars, foliar application of N had positive effect on the seed yield, protein content and wet gluten. The highest seed yield was observed in the Olga wheat cultivar - 5836 kg/ha with application of treatment 7. The same treatment induced highest yield 4904.67kg/ha and highest protein content - 14.57% in the second wheat cultivar – Podobrena Orovcanka. Treatments 2 and 3 showed the highest positive effect on the triticale seed yield, while foliar application of N did not affect the protein and wet gluten content. The results obtained by this study confirmed that foliar application of N at critical growth stages in wheat and triticale contributes to achieving optimal yield and quality.
