Contribution à l’étude des adventices dans la wilaya de Ain Témouchent (cas des parcelles de blé dur Triticum durum)

Abstract

The knowledge of the weed flora is a determining element for the implementation of any strategy of weed control in order to inventory the weeds of cereals (in particular durum wheat) of the region of the wilaya of Ain Temouchent and to have a knowledge on their biology and their ecology four plots of cultivated fields of the species Triticum durum were the object of phytoecological surveys. 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.
