Genetic yield gains of winter wheat in Germany over more than 100 years (1895-2007) under contrasting fertilizer applications
Ahrends, Hella Ellen; Eugster, Werner; Gaiser, Thomas; Rueda-Ayala, Victor; Hüging, H.; Ewert, F.; Siebert, Stefan (Journal article; Peer reviewed, 2018-09-27)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 ... -
Nutrient supply affects the yield stability of major European crops—a 50 year study
Ahrends, Hella Ellen; Siebert, Stefan; Rezaei, Ehsan Eyshi; Seidel, Sabine Julia; Hüging, Hubert; Frank, Ewert; Döring, Thomas; Rueda-Ayala, Victor; Eugster, Werner; Gaiser, Thomas (Peer reviewed; Journal article, 2020-12-18)Yield stability is important for food security and a sustainable crop production, especially under changing climatic conditions. It is well known that the variability of yields is linked to changes in meteorological ... -
Sensitivity analysis and Bayesian calibration for testing robustness of the BASGRA model in different environments
Hjelkrem, Anne-Grete Roer; Höglind, Mats; Van Oijen, Marcel; Schellberg, Jürgen; Gaiser, Thomas; Ewert, Frank (Journal article; Peer reviewed, 2017-09-10)Proper parameterisation and quantification of model uncertainty are two essential tasks in improvement and assessment of model performance. Bayesian calibration is a method that combines both tasks by quantifying probability ...
