The advantage of chemical weeding over weed harrowing does not always translates into an increase in crop yield, in particular when weed density is low and their competition with the crop is not intense (Garcia-Martin et al. 2007, Pardo et al. 2008, Lacroix at al. 2025).	cache/afs-159817.pdf	txt/afs-159817.txt
