Última Associating wheat crop and undersown forage legumes in organic agriculture: Incidence of forage legumes species Organic Eprints Celette, Florian; Goulevant, Gael; Amosse, Camille; David, Christophe. One of the key issues of organic arable systems is to increase use of N2 fixation from legume plants while enhancing autonomy by the limitation of off-farm inputs. Wheat yield in organic agriculture is generally low and variable. Grain yield and protein content are strongly affected by N deficiency and weed competition (Casagrande et al., 2009). Previous research had clearly demonstrated the benefits of forage legumes to improve N balance and preserve weed infestation (den Hollander et al., 2007). Several authors highlighted the interest of crop mixtures combining cereal and legumes to provide higher overall productivity, enhance ecological services and improve economical profitability (Malezieux et al., 2008). Nevertheless, previous research also... Tipo: Conference paper, poster, etc. Palavras-chave: Crop combinations and interactions Cereals; Pulses and oilseeds Farm nutrient management.

Reduction of soil tillage is of paramount importance for agricultural soil preservation. However, it is often accompanied by yield reduction and weed management problems. In this perspective, cover crops could play an important role to alleviate weed infestation and sustain yield. In this study, the results from a three-year experiment of cover crop cultivation in different soil tillage treatments is presented, together with results from DayCent simulations on the long term evolution of soil organic carbon and total nitrogen. Eight cover crop treatments were set up as subtreatments in a long term experiment in Switzerland. Cover crops were cultivated for a short two-month period between two winter wheats. Substantial differences in cover crop growth were... Tipo: Journal paper Palavras-chave: Soil quality Crop health; Quality; Protection Weed management. Ano: 2018 URL: http://orgprints.org/33968/1/B%C3%BCchietal_AEE_2018.pdf Wheat/forage legume intercropping in organic grain system: an answer to both weed and nitrogen deficiency issues Organic Eprints Amosse, Camille; Celette, Florian; Jeuffroy, Marie-Hélène; David, Christophe. Organic grain system managers have to find solutions to nitrogen deficiency and weed infestation. It is especially true when no animals are present on the farm to justify the use of forage legumes despite their interests in the crop succession. Our study focused on the role of four legume cover crop species inserted in a succession of winter wheat and maize on both problems. This insertion consisted in relay-intercropping the legumes under the canopy of wheat. Cover crops were maintained on the field after the harvest of the cereal until the sowing of the subsequent maize crop. The performance of the three crops of the succession was monitored as well as weed development and nitrogen dynamic in the soil-plant system. On the one hand, our results showed...

Ano: 2013 URL: http://orgprints.org/26014/1/Amosse_2013_CIAG_Vol32.pdf Incidence of soil N fertility on the performance of organic forage legume-wheat mixtures. Organic Eprints Celette, Florian; Goulevant, Gael; Amosse, Camille; David, Christophe. One of the key issues of organic arable systems is to bring enough nitrogen in the crop rotation to ensure satisfying crop nutrition. Wheat yield in organic agriculture are generally low and variable. Grain yield and grain protein content are strongly affected by N deficiency and weed competition (Casagrande et al., 2009). Nevertheless, the autonomy of the organic cropping systems has to be improved while off-farm inputs have to be limited. The use of N2 fixation from legume plants should then be improved. Previous research had clearly demonstrated the benefits of forage legumes in association to improve N balance and control weed seed bank. However, it is also well known that legume N2 fixation could be limited depending on the soil N fertility. The...
