In recent years spread of common mugwort (Artemisia vulgaris L.) among agricultural crops has increased significantly. The object of this research was to determine the allelopathic effect of the mugwort on winter wheat and winter oilseed rape germination and early growth. For the experiments aqueous extracts of aboveground part and the root biomass of mugwort at different concentrations were used. It was found that the highest total amount of phenolic compounds was in the mugwort leaves. Investigations showed that aqueous extracts of mugwort had no significant (P >= 0.05) influence on winter wheat seed germination while winter oilseed rape germination was significantly (P <= 0.05) inhibited by aqueous extract of mugwort roots at the 1:10 concentration. Winter wheat shoot and root growth was inhibited by all concentrations of aqueous extracts of the mugwort roots compared with the control. Winter oilseed rape shoot growth was significantly (P <= 0.05) stimulated, but the root growth significantly (P <= 0.05) inhibited by the highest concentration (1:10) of mugwort aboveground parts aqueous extracts.
