Most canola crops in Western Australia are swathed to harvest grain. After harvesting grain, the remaining canola plant material is dropped back onto the ground behind the harvester to form 'header rows' at about the same position where the swathed material was harvested. When wheat or barley are grown after swathed canola crops, frequently 'waves' appear in the crops. Growth of cereal plants is relatively good where the header row existed, but is much poorer between the rows from which the canola crop w
