Ursachen für Ertragsunterschiede in Betrieben mit unterschiedlicher Wirtschaftsweise und Betriebsstruktur in zwei Regionen Deutschlands

Summary in the original language of the document

In this study, winter wheat yields of organic and conventional farms with and without livestock in two regions in Germany were examined, with the aim of determining yield differences between the farming systems and possible reasons for these differences. Yields were 85% higher on conventional farms, mainly due to higher nitrogen input and the positive effects of chemical plant protection. The farms in North Rhine-Westphalia achieved higher yields than the farms in Bavaria. Climate was the most important factor, as lower temperatures during winter and higher precipitation during summer in Bavaria probably negatively affected yields. Differences in yield between farms with and without livestock could only be observed for conventional farms. The high intensity of farms without livestock resulted in higher yields.
