Effects of fertilizers on the grain yield (t/ha) and the development of mycobiota, especially of the Fusarium species, in winter wheat kernels were observed. Fertilizers were applied in the following variants: T1 - 30 cubic meter of slurry (pre-sowing treatment) and 25 cubic of slurry (top-dressing), T2 - 22.500 kg manure (pre-sowing treatment) and 220 kg of urea (top - dressing), T3 - 300 kg of urea (top-dressing) and T4 - the control without application of fertilizers. The application of nitrogen organic (slurry and manure) and mineral fertilizers (urea), individually or in a combination, affected the following: the increase of the wheat grain yield in treatments with fertilizers from 2.0 (T3) to 2.6 t/ha (T2) in relation to the control (T4); the intensities of infestation of species of the genus Fusarium in treatments with urea (T3), which were higher by 7.4, 2.4 and 1.8% than in treatments T4, T2 and T1, respectively; the intesity of infestation of species of the Alternaria in the treatment T3 (urea), which was lower by 7.5, 2.2 and 1.4% than in treatments T4 (control), T2 (manure + urea) and T1 (slurry, split application), respectively; the intesity of infestation of Fusarium graminearum in the treatment T3 (urea), which was higher by 7.3, 3.0 and 2.1% than in treatments T4, T2 and T1, respectively. Obtained results indicate a negative correlation between the grain yield and the intensity of infestation of species of the genus Fusarium (collectively) and Fusarium graminearum (indiviadually).
