Fig. 6. Simulated cumulative probability distribution of differences between the increased specific leaf area (SLA) and the normal SLA traits for (a, c, and e) maximum leaf area index (LAI_max) and (b, d, and f) grain yield for (a and b) Moora, (c and d) Wongan Hills, and (e and f) Merredin, Western Australia, for 0 kg N ha^-1 on a clay (_{_______}) and a sandy soil (_{___ . ___ . ___}) and 150 kg N ha^-1 on a clay (_{__ __ __ __}) and a sandy soil (_{___ .. ___ .. ___}). The vertical line (_...) represents zero.
