• Yield improvement and adaptation of wheat to water-limited environments in Australia—a case study (2014, background): “Figure 5 shows that the grain yield of a group of historic varieties grown in Western Australia from 1860 to 1982 is related to both year of release and thermal time to reach double-ridge formation (i.e. the beginning of floral development).”
• Crop rotation effects on yield of oilseed rape, wheat and barley and residual effects on the subsequent wheat (2015, background): “N fertilization was limited to 120 kg N ha being below site-specific N optimum for wheat in order to avoid that a high N supply covers the preceding crop or crop rotation effects (Seymour et al. 2012).”
• Break crops and rotations for wheat (2015, unknown): “It is even possible to see that themechanisms of break-crop benefits change over time as a cropping system evolves (Seymour et al. 2012).”
• The agronomic relevance of arbuscular mycorrhizas in the fertility of Australian extensive cropping systems (2012, background): “Overall, the break crop literature suggests no reason for farmers to avoid non-mycorrhizal break crops but, instead, that use should be encouraged along with mycorrhizal break crops for numerous reasons including enhanced yields in following cereal crops and greater N fertilizer use efficiency in fo”
• Magnitude and farm-economic value of grain legume pre-crop benefits in Europe: A review (2015, background): “For example, Angus et al. (2001) collated yield benefits compared to pure cereal sequences in Australia of 40–50% for low N levels and 10–17% for high N levels, however Seymour et al. (2012) found that in experiments conducted after 1990, benefits remained constant from zero to above 50 kg N ha−1.”
