Genetic yield gains of winter wheat in Germany over more than 100 years (1895–2007) under contrasting fertilizer applications

Environmental Research Letters, 2018
For highly productive regions such as Germany, the increase of wheat grain yields observed throughout the 20th century is largely attributed to the progress in crop breeding and agronomic management. However, several studies indicate a strong variability
