| Organic farming is based on to rely on a higher cropping systems diversity than its conventional counterpart and is regarded as one prototype to enhance the sustainability of agriculture and cereal-rich cropping systems. Nevertheless, organic arable crop rotations in temperate regions consist mainly of sole crops (SC; pure stands), with diverse pastures in farming systems with livestock being an exception (Hauggaard-Nielsen et al. 2001b). In organic farming, nitrogen (N) availability can be limiting especially in the absence of livestock (David et al. 2005ab) and causes cereal yield depressions and lower protein contents. For these reasons, integrating legumes with symbiotic fixation of atmospheric N2 is essential for balancing nitrogen exports from the... |

| Organically farmed pea, lupin and faba bean were compared in terms of dry matter (DM), grain yield and nitrogen (N) production, as well as for their competitive ability against weeds. Adjacent strips of pea, lupin and faba bean were set up at eight sites throughout the Pays de la Loire region. Soil conditions and weed pressure differed between sites. In general, faba bean produced slightly more grain yield and grain N than pea. Lupin was the least productive grain legume and the weakest competitor against weeds, though it provided grains with the highest N contents. However in most situations, pea was shown to be the most efficient until flowering for DM and N accumulation as well as for light interception and crop height. A faster development of... |

| The organic bread wheat market has been diversified over time through the emergence of different sale channels. Processors require organic bread wheat of higher quality and safety in order to meet the consumers’ demand. The overall objective of the AGTEC-Org project was to identify agronomical and technological ways to improve the performance of organic wheat and flour. The findings would contribute to enhanced baking quality and nutritional value of organic flour, as well as prevention of mycotoxin contamination. The project involved 9 research centers or universities from 5 European countries for a total budget of about 1.5 million €. More than 400 experimental treatments were analyzed from 23 agronomic trials and 4 lab-experiments on food technology.... |

| Increasing concerns about environmental impacts and reduction of inputs require a transformation of current cropping systems for better efficiency and sustainability (Cox and Atkins 1979; Jackson and Piper 1989; Vandermeer et al. 1998; Griffon 2006). New agronomic solutions are needed including multiple objectives like i) yield, ii) quality, iii) provision of ecological benefits and iv) the adaptation of production systems to climate change. Organic farming is regarded as a prototype to enhance the sustainability of present cereal-rich cropping systems. Organic farming is in general assumed to rely on higher crop diversity than its conventional counterpart. Nevertheless, organic arable crop rotations in temperate regions consist mainly of sole crops (SC)... |

| There is a lack of results on the advantages and limitations of combining different crop diversification strategies both in time and space, which makes it difficult for famers and advisers to find relevant information for the transition towards more diversified cropping systems. A network of ten field experiments (diverIMPACTS project) was built across seven European countries, covering a range of pedo-climatic conditions and different farming systems: arable and vegetable systems under both conventional and organic management. Each field experiment tests one or several diversified cropping systems, which combine three diversification strategies with low input practices. These diversified cropping systems are compared to reference systems, which are less... |

| The total organic area in the EU-27 had an annual average growth rate of nearly 15% from 1998 to 2006 with winter wheat being the most important cereal crop. Wheat yield in organic farming is around 30% to 70% of yield of conventional farming but higher premia for organic wheat may to some extent compensate for this. Bread wheat is grown in a variety of crop rotations and farming systems and four basic organic crop production systems have been defined. Nitrogen deficiency and weed infestation are considered to be the most serious threat in organic wheat production. Organic wheat producers will have to fulfil the technological needs of bakers although the requirements differ widely from small artisan bakers to large enterprises handling the organic bread... |

| Intercropping (the simultaneous growth of 2 or more species in the same field) is one way to solve some difficulties that organic supply chain has to face. The aim of this article is to assess the consequences and the compatibility with intercrops at 2 levels: i) cropping systems of 18 farmers from north of France and ii) the logistics ofagricultural cooperatives which collect durum wheat in Midi-Pyrenees altogether with two cooperatives that already had experimented intercrops (Terrena and AgriBioUnion).The conclusions of our work is that intercrops seem a priori compatible with farmers’ cropping systems and with the presentlogistic organization of cooperatives but the main difficulty remains the feasibility and the cost in sorting out grains. Constraints... |
