| Several agricultural practices can be used to control weed population thus avoiding the use of herbicides. Tillage, fertilization and growth of a green manure are found among them. In the context of a mid-term experiment set up in an organic field in Gallecs (Barcelona), we analysed the effect of chisel vs mouldboard ploughing, application of fertilizer and growth of a green manure on the density of weeds and on composition of the weed community. We evaluated weed density and community composition in April 2012 (spelt crop), February 2013 (green manure cover) and May 2013 (chickpea crop) and also analysed the sources of variation of density for the most abundant species in all periods. Our results show that, under the cereal crop, mouldboard plough had a... |

| Weed abundance, species richness and diversity in conventional and organic dryland cereal fields in Catalonia (NE of Iberian Peninsula) were compared to assess the effect of intensification on the floristic composition and structure of weed vegetation and to evaluate the role of organic farming in preventing the continued loss of biodiversity caused by intensive farming practices. Between 1 and 3 closely paired fields (blocks) were selected at 10 agricultural sites. Each pair contained one long-established organic farm and one conventional farm. Weed abundance, taking into account the spatial pattern, was surveyed in spring 2003 and 2004 by means of a relative abundance index for each species, ranking from one to six. Results show that abundance, species... |

| The adoption of non-inversion tillage practices has been widely promoted due to their potential benefits in reducing energy consumption and greenhouse emissions as well as improving soil fertility. However, the lack of soil inversion usually increases weed infestations and changes the composition of the weed community. Weed management is still a main drawback for the wider adoption of reduced tillage practices. However, it is not entirely clear whether these changes in weed communities are a consequence of non random filters on the functional attributes of weed species and may thus affect the potential weed-crop competition relationship. Here, we analyse the changes in weed diversity, community composition, and the functional attributes of weed... |
