Fig. 7. Simulated relative change in long-term average yields with incorporation of an increased specific leaf area (SLA) trait for (a) sandy and (b) clay soil in Western Australia and (c) loamy soils in New South Wales (Barellan and Pucawan) and a clay loam in Queensland (Warra) for six N treatments. Vertical lines show the upper 25% probability of occurrence base on the long-term simulation runs as an indicator of variability. Long-term simulated average yields of the normal SLA genotypes are shown in Table 3.
