Intercropping frost-sensitive legume crops with winter oilseed rape reduces weed competition, insect damage, and improves nitrogen use efficiency

Abstract: -Mixing plant species in agroecosystems is highlighted as an agroecological solution to reduce pesticides and fertilizers while maintaining profitability. In the French context, intercropping frost-sensitive legume crops with winter oilseed rape is potentially interesting and began to be implemented by farmers. In this study we aimed at measuring the services and disservices of this intercrop with three different legume mixtures, in terms of growth and yield for rapeseed, ground cover of weeds in autumn and da… Show more

“…The potential of legume–brassica intercropping has been investigated for various purposes in Europe, Asia, and North America, reflecting the endeavours of researchers to address problems and meet the farmers’ needs specific for these different agro-environments. In France, Sweden, and Canada, the weeds in oilseed rape are tackled by intercropping frost-sensitive legume as living mulch (Bergkvist, 2003; Thériault et al, 2009; Cadoux et al, 2015; Lorin et al, 2015). The advantage of intercropping annual legumes with cabbage and cauliflower in Turkey (Yildirim and Guvenc, 2005, 2006) and broccoli in the USA (Coolman and Hoyt, 1993) over sole crops, were demonstrated in vegetable production.…”

“…Results on rapeseed with companion legumes were presented by three teams. In France, rapeseed with a companion cover of legumes showed a reduction in weed cover and fall in insect damage, and an increase in the efficiency of nitrogen use (Cadoux et al, 2015). A team from the University of Caen showed under controlled conditions (Génard et al) 1 that the amount of nitrogen in the soil increases with legumes, especially with lupine, to a lesser extent with clover and little or not with vetch.…”

“…La structure et le fonctionnement biologique du sol sont favorables à une meilleure robustesse des plantes, car les rendements des associations sont à la fois plus élevés et plus stables que les mêmes espèces en culture mono-spécifique sur des surfaces équivalentes (Corre-Hellou et al, 2013). L'utilisation de couverts gélifs de légumineuses sous colza est une pratique qui confirme son intérêt depuis 2011 dans certains contextes pédoclimatiques (Cadoux et al, 2015). Sa maîtrise permet de conforter l'implantation du colza, de réduire de 30 kg l'azote apporté, tout en cumulant le maintien du rendement, voire son augmentation (de 10 % ou plus en conditions difficiles), avec même une réduction possible des herbicides et insecticides, avec des baisses des attaques d'altises et de charançons du bourgeon terminal.…”
