Intercropping of cereal and grain legumes in European cropping system (INTERCROP) is an European Project in which a multidisciplinary team of scientist conducts research on intercropping under different regional organic cropping systems. The project’s core experiments was a field trial in which pea and barley were intercropped in spring sowing and compared with respective sole crops during 2003-2005. One of the main deliverables of the Project (Workpackage 2) was the evaluation of agronomic performance of intercrop in term of yield advantage and yield stability. Results of this activity carried out, in five European Countries (Denmark, France, Germany, Italy and United Kingdom) in the basic field experiments, are presented in this contribution.

Evaluation of the STICS crop model within the INTERCROP EU project to simulate pea-barley intercropping systems. 21
Launay, doctor Marie; Brisson, doctor Nadine; Corre-Hellou, doctor Guenaëlle; Dibet, Audrey; Crozat, doctor Yves; Hauggard-Nielsen, doctor Henrik; Kasyanova, doctor Elena; Monti, doctor Michele; Dahlmann, Christopher.
This work is devoted to the evaluation and utilization of the STICS intercrop/sole crop model taking into account the European environmental variability within an organic farming framework. The model ability to simulate intercropping systems was evaluated on the network of the INTERCROP EU project experiments. We first realized the difficulty to simulate relevant absolute production values in spite of a satisfactorily phase of parameterisation in conventional farming experiments. We attributed most of the discrepancies between simulations and measurements to the non accounting of biotic stresses. However, the relative values and in particular the Land Equivalent Ratios draw to the same results for simulation and observa-tion, i.e. the global advantage of...

Pea-barley intercropping for the control of weeds in European organic cropping systems 21
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 21
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

Performance of pea, lupin and faba bean, in organic cropping systems in France 21
Dibet, Audrey; Corre-Hellou, Guénaëlle; Aveline, Anne; Crozat, Yves.
Organically farmed pea, lupin and faba bean were compared in terms of dry matter (DM), grain yield and nitrogen (N) production, as well as for their competitive ability against weeds. Adjacent strips of pea, lupin and faba bean were set up at eight sites throughout the Pays de la Loire region. Soil conditions and weed pressure differed between sites. In general, faba bean produced slightly more grain yield and grain N than pea. Lupin was the least productive grain legume and the weakest competitor against weeds, though it provided grains with the highest N contents. However in most situations, pea was shown to be the most efficient until flowering for DM and N accumulation as well as for light interception and crop height. A faster development of...
