Yield dent (see text) for maize under actual (a) conditions and differences in yield dent for uWN-actual (b), uW-actual (c), and uN-actual (d) for all grid cells with at least 100ha maize cropland [38] and a minimum yield of 0.5 tDM ha^-1.

<p>Yield dent (see text) for maize under actual (a) conditions and differences in yield dent for uWN-actual (b), uW-actual (c), and uN-actual (d) for all grid cells with at least 100ha maize cropland [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0198748#pone.0198748.ref038" target="_blank">38</a>] and a minimum yield of 0.5 tDM ha^-1.</p

CV of global maize, wheat, rice, and soybean productivity (%) over 28 years (1981–2008) of the 10 individual GGCMs, their ensemble median and FAO statistics [39].

<p>Data are shown for actual, unlimited (uWN), unlimited nutrients (uN) and unlimited water (uW) conditions and have been detrended prior to computing CVs. FAO data is only available for actual conditions. For better readability, the lowest CVs per model (rows) are colored green, highest are colored orange.</p

GGCMs participating in the study, model type and key references, as well as nutrients considered in crop model simulations (N: nitrogen, P: phosphorus, K: potassium).

Global distribution of relative (%) temporal yield variability per production system (actual, uW, uN, uWN) and GGCM per grid cell for maize.

<p>Colored bars show the interquartile range of yield CVs across all grid cells with at least 100ha maize cropland [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0198748#pone.0198748.ref038" target="_blank">38</a>] and a minimum yield of 0.5 tDM ha^-1. Black lines within the bars show the median, dashed whiskers extend to the maximum value with 1.5 times the interquartile range and values outside this range are classified as outliers and depicted as dots. Yield CV of more than 100% are not shown.</p

Changes in CV from purely rainfed to fully irrigated systems with current nitrogen (uW-rf).

<p>The CV can increase in regions where different growing seasons are specified for irrigated and rainfed systems [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0198748#pone.0198748.ref015" target="_blank">15</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0198748#pone.0198748.ref038" target="_blank">38</a>]. Maps show data of the GGCM ensemble median for all grid cells with at least 100ha maize cropland [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0198748#pone.0198748.ref038" target="_blank">38</a>] and a minimum yield of 0.5 tDM ha^-1.</p
