| Intra-row weed emergence in row crops can be reduced by means of a biennial cultivation system that is based on an exhaustion of the weed seedbank in the upper soil layer of crop-free bands established in a preceding cereal crop, year I, prior to the row crop, year II. In this study, a series of field experiments is presented focussing more specifically on the influence of prevention of weed seed shedding and of different cultivation tactics in the system on intra-row weed emergence in the bands in year II. As the system excludes inverting soil tillage between year I and year II, the prevention of weed seed shedding in year I turned out to be a key factor for achieving the desired effect of the system. This was seen with spring barley grown in year I but... |
