Inventaire sur les mauvaises herbes des cultures maraichères dans la Wilaya de Ain Temouchent

Abstract

In order to inventory the weeds of the vegetable crops (in particular tomato, bean, pea and onion) of the region of Ain larbaa (wilaya of Ain Temouchent) and to have a knowledge on their biology, cultivated field was the object of phytoecological surveys. The floristic analysis of all the surveys carried out counts 26 weed species belonging to 14 families. The ratio of the number of monocotyledonous species to the number of dicotyledonous species is significant, which confirms the predominance of dicotyledons with 25 species. The biological type for all the species recorded shows that annuals dominate. Perennial weeds are well represented (3 species), as well as the presence of biennials (1 species). The onion crop is the most vulnerable to weed competition.
