| Effects of reduced tillage, fertilization and green manures on the weeds and crop yields in a cereal-legume crop rotation under organic farming. On 2011, we established a long-term experiment to evaluate the effects of reduced tillage (chisel vs mouldboard plough), fertilization with semicomposted manure and sowing of green manures before spring crops, on the crop yields and weed abundance in a 5-year rotation (spelt, chickpea, wheat, lentil and spelt). After five years, there was not noticeable increment in weed abundance or richness. Reduced tillage caused a significant increase of weeds compared with mouldboard plough, but it this increase did not cause significant yield loss in cereal crops compared with mouldboard plough. Green manures exerted a... |

| Cocoa production systems can vary from a mono-cropping (MC) full sun plantation to a highly diversified successional agroforestry (SAFS). Mono-cropping is still the most common one but recently agroforestry (AF) systems have raised more interest because of their expected long term resilience. Nevertheless, information about the influence of cropping systems and management methods such as organic versus conventional in cocoa production and phenology in South America is missing. This study is based on the SysCom program’s framework located in Alto Beni (Bolivia), where three cropping system (MC, AF and SAFS) are compared. Additionally, MC and AF systems are conventionally and organically managed. A total of 12 cultivars including local clones, foreign... |

| The incorporation of conservation agriculture techniques (e.g. reduced tillage and green manures) in organic farming systems brings many benefits to the environment and reduces energy use (Holland, 2004). One of the main drawbacks of the use of reduced tillage is the potential increase in weed infestation and shifts in the weed community composition, sometimes to the benefit of more difficult-to-control species (Bàrberi, 2002; Peigné et al., 2007; Sans et al., 2011). However, weeds have an important role in maintaining farmland functional biodiversity (Bàrberi et al, 2010; Caballero et al., 2010), and this should be balanced with their potential negative impact on crop yield and quality. Within the frame of the European project “Reduced tillage and green... |

| One of the objectives of the TILMAN-ORG Project is to improve weed management under conservation agriculture (reduced tillage and/or cover crops) in organic arable systems. The shift from ploughing to conservation agriculture should not only maintain crop yield but possibly improve weed community diversity. This paper summarises the results on (1) weed abundance, (2) weed diversity and (3) crop yield obtained in the first year of the project (2012) in 13 trials scattered across Europe. |

| Reduced tillage may improve the environmental and economic performance of organic farming. Reducing the intensity of soil tillage decreases the energy consumption and the emission of carbon dioxide, and could increase carbon sequestration (Holland 2004). Reduced tillage also may improve water retention and reduce soil erosion (Berner et al 2008). One of the main drawbacks of the reduced tillage practices is the potential increase of weed infestation and changes in weed species composition, sometimes to the benefit of species which are more difficult to control, such as perennial and grass species (Peigné et al 2007; Teasdale et al 2007; Sans et al 2011). Organic farmers commonly keep weeds under control by ploughing and by post-emergence mechanical... |
