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