Abstract:
In the production of cereals under pivots, the adventitious ones constitute an important constraint by the harmful effects
which they cause with the cultures.
The fight against these undesirable plants necessarily passes by their identification. This work proposes to
inventory and follow, in a farm of the area of El Goléa, the evolution of the adventitious flora present in a culture under
durum wheat pivot variety siméto (weeded stations and not weeded stations) like of except pivot.The study, made it
possible to emphasize a richness specific (37 species) pertaining to 12 botanical families to their head comes that from
Asteraceae and 07 kinds, with however of the differences in contribution of these families and species to the total flora.
30espèces is listed exclusively inside the culture and 7 species are only of except pivots, with 3espèces non given, that
is to say in total 40éspèces.
