... evealed that the direct sowing caused higher infection of spring wheat by the stem base and root diseases. Higher infection of Fusarium spp. and Gaeumannomyces graminis was observed on the treatments without white mustard biomass each year of the study. Percentage of damage plants and the index of infection caused by pathogens of stem base diseases depended on the experimental factors of the studies. Higher infection was observed on the treatments without cover crop cultivation where spring wheat was cultivated in no-tillage technology.
