Three types of stubble tillage were compared to a control which consisted of not cultivating the stubble after harvest. The treatments were: chiselling (15 cm), shallow ploughing (7 cm) and rototillering (5 cm). In autumn all treatments were ploughed at 25 cm depth. So far, stubble tillage has not had any significant effects on weeds or yields. However, there was a tendency of stubble tillage having an impact on perennial weeds.
