| 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.
