Figure 3 is incorrect because the simulations depicted are not, in fact, based on data obtained in the presence of unlimited nitrogen. The correct figure is presented below. The data shown now match those in Table 4.
The authors apologise for the error.
Fig. 3. Simulated mean frost–heat-adjusted grain yields of four wheat maturity types sown at 2-week intervals at 13 locations across Australia’s high-rainfall cropping zone. The four maturity types were a slow winter type (●), a fast winter type (○), a medium spring type (■), and a fast spring type (□). Data presented are for a crop density of 150 plants/m2 with unlimited N provided throughout crop growth.
