Objetive: the presence of weeds in a cereal field is detrimental for several reasons. In this study, we chose four adventitious species to test their allelopathic effect on the germination of seeds and the development of seedlings of the durum wheat variety "Simeto".

Design/Methodology/Approach: we tested the allelopathic effect at the laboratory level, by mixing weed seeds and durum wheat. In these trials, the allelopathic effect was measured.

Results: the inhibitory effect of these adventitious species manifests itself much more on the development of the seedlings, especially on the aerial parts.

Findings/Conclusions: the bindweed (Convolvulus arvensis L) is the most inhibiting.
