Ertrag und Qualitätsparameter von Winterweizensorten aus biologischer und konventioneller Züchtung in Luxemburg Organic Eprints
Klaedtke, Stephanie; Zimmer, Steffi; Aendekerk, Raymond.
Thirteen winter wheat varieties (Triticum aestivum L.) bred in conventional breeding programs and seven varieties from organic breeding were tested under organic conditions in two locations in 2009/10 and 2010/11 in Luxembourg. The objective was to analyze whether these conditions, organic varieties perform better than conventional ones. Grain yield (dt ha-1), protein content (%) and Zeleny sedimentation value were analyzed. The effect of the factor variety was statistically significant at a probability level of 0.05 for the three traits. For grain yield, the variety x year x location interaction was significant. For protein content, the variety x year interaction was significant. Location x year interaction was significant for sedimentation value. Results...

Ökonomisch-ökologische Analyse von biologisch und konventionell wirtschaftenden Betrieben in Luxemburg Organic Eprints

The aim of this paper is to analyse the cost-effectiveness of payments to organic farms in Luxemburg from an agri-environmental perspective. For pursuing this aim, farm accountancy data, farm structure data and 7 environmental indicators were assessed for 12 organic and 12 conventional dairy and suckler-cow farms. Results show that organic farms cause substantially lower environmental impacts than their conventional counterparts. However, these additional environmental benefits do not go along with higher public payments. Therefore, we argue that agricultural policy in Luxemburg currently does not provide incentives for ecological friendly agricultural production in a sufficiently targeted way.

REDUCED TILLAGE AND COVER CROPS IN ORGANIC ARABLE SYSTEMS PRESERVES WEED DIVERSITY WITHOUT JEOPARDISING CROP YIELD Organic Eprints
Barberi, Paolo; Aendekerk, Raymond; Antichi, Daniele; Armengot, Laura; Berner, Alfred; Bigongiali, Federica; Blanco-Moreno, José Manuel; Carlesi, Stefano; Celette, Florian; Chamorro, Lourdes; Crowley, Oliver; Döring, Thomas; Grosse, Meike; Haase, Thorsten; Hess, Jürgen; Huiting, Hilfred; José-Maria, Laura; Klaedtke , Stéphanie; Kranzler, Andreas; Luik, Anne; Peigne, Joséphine; Sukkel, Wijnand; Surböck, Andreas; Talgre, Liina; Sans, Francesc Xavier.
One of the objectives of the TILMAN-ORG Project is to improve weed management under conservation agriculture (reduced tillage and/or cover crops) in organic arable systems. The shift from ploughing to conservation agriculture should not only maintain crop yield but possibly improve weed community diversity. This paper summarises the results on (1) weed abundance, (2) weed diversity and (3) crop yield obtained in the first year of the project (2012) in 13 trials scattered across Europe.

Vergleichende ökonomisch-ökologische Analyse von biologisch und konventionell wirtschaftenden Betrieben in Luxemburg („öko-öko“) Organic Eprints
Schader, Christian; Müller, Adrian; Zimmer, Steffi; Aendekerk, Raymond; Lioy, Rocco; Reding, Romain; Conter, Gerard; Adam, Simone; Dahlem, Richard; Moes, Georges.
International gibt es zahlreiche vergleichende Untersuchungen von ökonomischen oder ökologischen Leistungen von biologisch und konventionell wirtschaftenden Betrieben (Baumgartner et al., 2010; Offermann and Nieberg, 2000; Olesen et al., 2006). Dabei werden meist aber entweder ökonomische oder ökologische Wirkungen untersucht. Studien, die beide Aspekte zu einer übergreifenden Sichtweise vereinen, sind rar (Schader, 2009). Dabei sind gerade solche integrierte Studien aus agrarpolitscher Sicht höchst relevant. Denn bei der Gestaltung der Gemeinsamen Agrarpolitik (GAP) auf Mitgliedsstaatenebene spielt die Frage der Ausrichtung der Maßnahmen eine zentrale Rolle. Die Pläne zur ländlichen Entwicklung und die darin beinhalteten Agrarumweltprogramme bilden die...
