– Intercropping of cereals and grain legumes is a technology to enhance biodiversity in organic agro-ecosystems, enhance and stabilize yields and make better use of plant growth resources. Here we report the preliminary results of the EU FP 5 research project “Intercrop” carried out in five European regions. The project demonstrates several significant benefits which could be exploited to a greater degree in European organic farming .

Pea-barley intercropping for the control of weeds in European organic cropping systems Organic Eprints
Dibet, Audrey; Hauggaard-Nielsen, Henrik; Kasyanova, Elena; Ruske, Rachel; Gooding, Mike; Pristeri, Aurelio; Monti, Michele; Dahlmann, Christoph; von Fragstein, Peter; Ambus, Per; Jensen, Erik; Crozat, Yves.
Two pea-barley intercropping strategies were compared with respective sole crops for their capacity to reduce weeds. Crops were grown under organic conditions without mechanical weeding. Field trials were carried out during three years throughout Europe. Although crops were tested under diverse soil and climate conditions, in the presence of different weed species and varying weed biomass, it appeared in all experimental sites that weeds were better controlled in barley sole crop or in intercrops than in pea sole crop. Differences in the degree of weed control between crop treatments were already visible at flowering and sometimes increased until maturity. It is interesting to note that the substitutive and additive designs obtained similar results. The...

Pea-barley intercrops use nitrogen sources 20-30% more efficiently than the sole crops Organic Eprints
Hauggaard-Nielsen, Henrik; Ambus, Per; Brisson, Nadine; Crozat, Yves; Dahlmann, Christoph; Dibet, Audrey; von Fragstein und Niemsdorff, Peter; Gooding, Mike; Kasyanova, Elena; Launay, Marie; Monti, Michele; Pristeri, Aurelio; Steen Jensen, Erik.
Field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L) were intercropped and sole cropped to compare the effects of crop diversity on the use of nitrogen sources in European organic crop-ping systems. Across a wide range of growing condi-tions pea-barley intercropping showed that nitrogen sources were used from 17 to 31% more efficiently by the intercrop than by the sole crops. Intercropping technologies offers the opportunity for organic cropping systems to utilize N complementarity between component crops, without compromising total crop N yield levels
