abstract:
The paper presents the results of a study on the influence of plough and no-tillage systems in combination with various tillage depths on species composition, number and air-dry mass of weeds in soybean canopy. The three-year study revealed that the no-tillage system and deep cultivation caused an apparent increase of majority of dominating weeds number as compared to the plough and shallow tillage systems. The tillage systems studied in the experiment significantly modified the number and air-dry mass of weeds. Higher values of both traits were recorded under no-tillage cultivation conditions: weed number by 54.6%, and air-dry mass of weeds by 51.7% higher than in objects with plough tillage. The tillage depth significantly differentiated the weed number per 1 m2. In objects with deep tillage cultivation, that trait value was higher by 68.0% than under conditions of shallow tillage.
