AN ALTERNATIVE APPROACH TO PLANT HEALTH: THE PROCEDURAL CONCEPT APPLIED TO COMMON BEAN SEED SYSTEMS Organic Eprints
Klaedtke, Stephanie; Stassart, Pierre; Chable, Véronique.
Pathogen-free seed is one strategy to protect plants and prevent the introduction and spread of dangerous pests. While this strategy reduces damage to crops and delays the global spread of pathogens, it may also be regarded as an overly reductionist approach to plant health disfavoring the resilience of cropping systems. Rather than defining plant health as an objective entity, a procedural concept consisting of a set of rules for debate in order to incorporate different viewpoints on the continua between naturalist and normativist approaches, negative and positive definitions, reductionism and holism and functionality and resilience has been proposed. In the ongoing research project presented here, the questions suggested are applied to the case of...

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...
