Paper doi abstract bibtex The competitive ability of five prominent weeds species that have the potential to interact in soybean cropping systems of Argentina (Amaranthus quitensis, Chenopodium album, Digitaria sanguinalis, Setaria verticillata and Tagetes minuta) was evaluated in two greenhouse experiments (Exp. 1 and Exp. 2). Crop and weeds were grown in all pairwise mixtures using an additive competition design. Competitive ability was evaluated through competitive indices based on species total biomass. Both experiments showed asymmetric competitive interactions between species, resulting in a competitive network predominantly transitive involving up to four from six species in Exp. 1: Glycine. max \textgreater C. album \textgreater D. sanguinalis \textgreater (A. quitensis, S. verticillata and T. minuta) and up to three from six species in two pathways in Exp. 2: G. max \textgreater D. sanguinalis \textgreater (C. album, S. verticillata and T. minuta); and G. max \textgreater A. quitensis \textgreater (C. album, S. verticillata and T. minuta). The hierarchical relationship between species found in this study has implications on weed population dynamics in the context of community assembly framework. We discuss engineered management practices that consider the use of the crop and weed competitive ability to modulate the community structure and the rationalization in the use of herbicides directed to avoid environmental damage.
