The winter wheat yield depends on nitrogen fertilization and on the total precipitation in the main yield-forming months of May and June. Nitrogen fertilization and precipitation in excess of the maximum yield lead to yield reductions. Climate change results in yield reductions with lower monetary returns at high temperatures in May/June of more than 15 degrees. The increased CO2 emissions of the last 25 years, as well as breeding progress, have so far led to yield increases of 50% for winter wheat in Germany. The author underpins his explanations and conclusions, which are presented on the basis of several studies, with numerous data and figures for a better understanding.
