The weed flora of all the plots was recorded and the ratio of the number of monocotyledonous species to the number of dicotyledonous species (M/D) was determined. The results of the study for all the species surveyed show that annuals dominate; perennial weeds are well represented, as well as biennials. Most of these species are of Mediterranean origin.nventory- weeds, biology, ecology, durum wheat
