Intercropping of cereals and grain legumes for increased production, weed control, im-proved product quality and prevention of N –losses in European organic farming systems Organic Eprints
Jensen, Erik Stee; Ambus, Per; Bellostas, Natalia; Boisen, Sigurd; Brisson, Nadine; Corre-Hellou, Guanelle; Crozat, Yves; Dahlmann, Christoph; Dibet, Audry; von Fragstein, Peter; Gooding, Mike; Hauggaard-Nielsen, Henrik; Kasyanova, Elena; Monti, Michele; Pristeri, Aurelio.
– 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...

Influence of different seed rates, sowing techniques and N supply on grain yield and quality parameters in intercropping systems Organic Eprints
Dahlmann, Christoph; von Fragstein und Niemsdorff, Peter.
Abstract - Field experiments with spring wheat and faba bean were carried out at the Hessian State Estate Frankenhausen located near Kassel in Central Germany in 2003 - 2005. As part of the EU Project “Intercrop”, spring wheat and faba bean were sown out as sole crops and intercropped with different seed rates, using two sowing techniques and with and without N supply. Intercropping was able to increase yield in the most treatments. All LER’s were higher than 1 and the N content in grain also increased in intercropped variants. The influence of the sowing technique was rather low in comparison to the seed rate.

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

Einfluss unterschiedlicher Konkurrenzverhältnisse beim Mischanbau von Som-mergerste und Erbse auf den Kornertrag, die Kornqualitäten und der symbiontischen N2-Fixierung Organic Eprints
Dahlmann, Christoph; von Fragstein und Niemsdorff, Peter.
Field experiments with spring barley (Hordeum vulgare L.) and field pea (Pisum sativum L.) were carried out in three subsequent growing seasons 2004 to 2006 at the Hessian State Estate Frankenhausen located near Kassel in Central Germany. Spring barley and field pea were sown out as sole crops and intercropped with different seed rates in replacement and additive design, using two sowing modes: row by row (IC) and mixed intercropping (MC). Intercropping (IC and MC) was able to increase grain yield in most of the treatments. The Land Equivalent Ratio (LER) was always higher than 1, indicating that plant growth factors were used more efficiently by the intercrop than by the sole crop. Besides, the N content in spring barley grain was increased by...

Entwicklung von Strategien zur Ausdehnung des Ökologischen Landbaus in Luxemburg Organic Eprints
Szerencsits, Manfred; Ruppert, Jim; Dahlmann, Christoph; Hess, Juergen.
To develop strategies for the increase of organic production in Luxemburg, NGOs have initiated this empirical study. In total about 120 farmers will be interviewed to investigate motives and barriers for conversion and attitudes towards organic farming. Results are recommendations for political activities, information and advice. First results show surprising similarities with a study in Lower Saxony in 2003: Motives and barriers for conversion seem to be relatively independent of structural conditions and the development of the organic market. The differences are more obvious according to farmers interest, attitudes and knowledge about organic farming.
