It is well known that the variability of yields is linked to changes in meteorological conditions. However, little is known about the long-term effects of agronomic management strategies, such as the supply of important nutrients. We analysed the stability of four major European crops grown between 1955 and 2008 at a long-term fertilization experiment located in Germany. Six fertilizer treatments ranged from no fertilization over the omission of individual macronutrients to complete mineral fertilization with all major macronutrients (nitrogen, phosphorus, potassium and calcium). Yield stability was estimated for each crop × treatment combination using the relative yield deviation in each year from the corresponding (nonlinear) trend value (relative yield anomalies (RYA)). Stability was lowest for potato, followed by sugar beet and winter wheat and highest for winter rye. Stability was highest when soils had received all nutrients with the standard deviation of RYA being two to three times lower than for unfertilized plots. The omission of nitrogen and potassium was associated with a decrease in yield stability and a decrease in the number of simultaneous positive and negative yield anomalies among treatments. Especially in root crops nutrient supply strongly influenced both annual yield anomalies and changes in anomalies over time. During the second half of the observation period yield stability decreased for sugar beet and increased for winter wheat. Potato yields were more stable during the second period, but only under complete nutrient supply. The critical role of potassium supply for yield stability suggests potential links to changes in the water balance during the last decades. Results demonstrate the need to explicitly consider the response of crops to long-term nutrient supply for understanding and predicting changes in yield stability."],["dc.identifier.doi","10.1088/1748-9326/abc849"],["dc.identifier.eissn","1748-9326"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/83134"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.publisher","IOP Publishing"],["dc.relation.eissn","1748-9326"],["dc.relation.orgunit","Department für Nutzpflanzenwissenschaften"],["dc.relation.orgunit","Abteilung Pflanzenbau"],["dc.relation.orgunit","Fakultät für Agrarwissenschaften"],["dc.rights.uri","http://creativecommons.org/licenses/by/4.0"],["dc.title","Nutrient supply affects the yield stability of major European crops—a 50 year study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

To meet the expected grain demand by mid-century, wheat breeding strategies must continue to improve upon yield-advancing physiological traits, regardless of climate change impacts. Here, the best performing doubled haploid (DH) crosses with an increased canopy photosynthesis from wheat field experiments in the literature were extrapolated to the global scale with a multi-model ensemble of process-based wheat crop models to estimate global wheat production. The DH field experiments were also used to determine a quantitative relationship between wheat production and solar radiation to estimate genetic yield potential. The multi-model ensemble projected a global annual wheat production of 1050 ± 145 Mt due to the improved canopy photosynthesis, a 37% increase, without expanding cropping area. Achieving this genetic yield potential would meet the lower estimate of the projected grain demand in 2050, albeit with considerable challenges."],["dc.description.sponsorship","Ministry of Education, Youth and Sports of Czech Republic SustES"],["dc.description.sponsorship","International Wheat Yield Partnership (IWYP)"],["dc.description.sponsorship","Biotechnology and Biological Sciences Research Council (BBSRC)"],["dc.description.sponsorship","National Natural Science Foundation of Chinahttp://dx.doi.org/10.13039/501100001809"],["dc.description.sponsorship","Chilean Technical and Scientific Research Council (CONICYT) FONDECYT Project"],["dc.description.sponsorship","International Maize and Wheat Improvement Center (CIMMYT)"],["dc.identifier.doi","10.1088/1748-9326/aca77c"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/118610"],["dc.language.iso","en"],["dc.relation.eissn","1748-9326"],["dc.rights","CC BY 4.0"],["dc.rights.uri","http://creativecommons.org/licenses/by/4.0"],["dc.title","Evidence for increasing global wheat yield potential"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

This study uses an ensemble of crop models applied on a spatial grid to quantify the contributions of various climatic drivers to past yield variability in grain maize and winter wheat of European cropping systems (1984–2009) and drivers of climate change impacts to 2050. Results reveal that for the current genotypes and mix of irrigated and rainfed production, climate change would lead to yield losses for grain maize and gains for winter wheat. Across Europe, on average heat stress does not increase for either crop in rainfed systems, while drought stress intensifies for maize only. In low-yielding years, drought stress persists as the main driver of losses for both crops, with elevated CO2 offering no yield benefit in these years."],["dc.identifier.doi","10.1038/s41467-018-06525-2"],["dc.identifier.eissn","2041-1723"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15612"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/73764"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.notes.intern","Merged from goescholar"],["dc.relation.orgunit","Department für Nutzpflanzenwissenschaften"],["dc.relation.orgunit","Fakultät für Agrarwissenschaften"],["dc.relation.orgunit","Abteilung Pflanzenbau"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0/"],["dc.title","Diverging importance of drought stress for maize and winter wheat in Europe"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
