| Cadmium(Cd) uptake by cocoa has recently attracted attention, after the European Union (EU) decided to establish values for tolerable Cd concentrations in cocoa products. Bean Cd concentrations from some cocoa provenances, especially from Latin America, were found to exceed these values. Cadmium uptake by cocoa is expected not only to depend on a variety of soil factors, but also on plant and management factors. In this study, we investigated the influence of different production systems on Cd uptake by cocoa in a long-term field trial in the Alto Beni Region of Bolivia,where cocoa trees are grown inmonocultures and in agroforestry systems, both under organic and conventional management. Leaf, fruits and roots of two cultivars were sampled fromeach... |

| There is a growing interest in the use of functional approaches for the study of weed assemblages, to disentangle underlying processes determining their composition and dynamics. Functional approaches are based on the assumption that weed community composition and dynamics can be best explained by a set of species traits expressing their response to agricultural disturbance. This knowledge should help develop more sustainable, ecologically based weed management systems. Trait‐based data required for this kind of analysis are available from various sources, but most of them either cover mainly non‐weedy species or, in the case of weed‐focussed trait databases, they cover a limited number of species. In this work, we present a trait database for 240 weed... |

| In recent years, the limitations of top-down approaches for development-oriented research have become apparent. Therefore, scientists have started to explore alternatives such as participatory research. By involving many stakeholders throughout the different stages of innovation development, participatory research helps tackling the multi-faceted challenges the global food system is facing today. Since almost a decade, the Research Institute of Organic Agriculture (FiBL) has been running a large program called “Farming Systems Comparison in the Tropics” (SysCom) in Bolivia, India and Kenya. Besides maintaining four Long-Term farming systems comparison Experiments (LTE), Participatory On-farm Research (POR) is a strong component of SysCom. In POR, we aim... |

| 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... |

| 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... |

| Conservation tillage could provide environmental benefits to organic farming. However, potential weed problems often tend to discourage farmers from adopting it. The effects of tillage (reduced vs. conventional), fertilisation (slurry vs. manure compost) and the application of biodynamic preparations (with and without) on crop yield and on weed cover, diversity and biological attributes were investigated in a cropping sequence of wheat, sunflower and spelt. Total weed cover and perennial cover in reduced tillage treatments were two to three times greater than in conventional treatments. Monocotyledon cover in reduced tillage was three times that in conventional tillage in spelt, whereas the dicotyledon Stellaria media dominated in sunflower. Weed diversity... |
