• Traits and selection strategies to improve root systems and water uptake in water-limited wheat crops. (2012, background): “Modelling suggests that the narrowing of shoot and root architectures in higher density, earlier-sown cropping systems underlies yield gains in these environments, which have relatively high, predictable rainfall during the growing season (Hammer et al., 2009).”
• Comparing solar radiation interception and use efficiency for the energy crops giant reed (Arundo donax L.) and sweet sorghum (Sorghum bicolor L. Moench) (2013, background): “A reduction of k leads to more even penetration of light into the canopy, and implies more uniform distribution of photosynthesis across the canopy (Hammer et al., 2009).”
• Morphological and architectural development of root systems in sorghum and maize (2010, positive): “A narrow root angle may affect the vertical distribution of roots through deeper rooting, which can improve water capture at depth and thus positively affect drought adaptation (Hammer et al. 2009; Kato et al. 2006; Oyanagi 1994).”
• Microbially Mediated Plant Functional Traits (2011, background): “…on root traits has been one of the key determinants of increased yield in crop plants, enabling higher planting densities in crops such as maize (Hammer et al., 2009); recent work in M. truncatula populations shows that root diameter and root length experience significant total natural…”
• Changes in Nitrogen Use Traits Associated with Genetic Improvement for Grain Yield of Maize Hybrids Released in Different Decades (2013, background): “Although a range of maturities (661–724°C∙d) as determined by time to 50% silk exsertion existed in the panel of era hybrids (Table 1), this range of maturities is typical for commercial maize hybrids that might be grown in east-central Illinois.”
• Nonlinear Regression Models and Applications in Agricultural Research (2015, background): “…have been applied in agricultural science to describe the rate of phenological development as a function of temperature (e.g., Yin et al., 1995), the size of a leaf as a function of its rank in a plant (e.g., Hammer et al., 2009) or soil moisture effects on N2O emissions (e.g., Rafigue 2011).”
• Industry-Scale Evaluation of Maize Hybrids Selected for Increased Yield in Drought-Stress Conditions of the US Corn Belt (2015, background): “Breeders have long been selecting for tolerance to biotic and abiotic stress (Cooper et al., 2014a; Duvick et al., 2004; Hammer et al., 2009).”
