Resumo: | Due to limited nutrient conditions in organic farming winter wheat cultivars can often  not perform to the full extent of their genetic potential. This study aims to assess  nutrient acquisition potential and yields of old, organically and conventionally bred  winter wheat cultivars. Ten cultivars were tested within the DOK long-term experiment  in two organic systems at low and moderate intensity, a conventional stockless system  and an unfertilized control. Yields and nutrient contents of grain and straw were  significantly affected by cultivars and systems. Cultivar x system interactions were not  detected. Yields were increasing with nutrient level and year of release of cultivars.  Under organic conditions all cultivars performed equally well with respect to yield.  Grain nitrogen content was increasing in line with nitrogen input, but dropping along  year of release of cultivar.
