Changes in Nitrogen Use Traits Associated with Genetic Improvement for Grain Yield of Maize Hybrids Released in Different Decades (2013, background): “Differences in grain yield at high N have been attributed to contributions from both N uptake and utilization with varying degrees of importance being assigned to each of these traits by past studies (Kamprath et al., 1982; Moll et al., 1982; Presterl et al., 2002; Worku et al., 2007).”
Plant biomass and nitrogen partitioning changes between silking and maturity in newer versus older maize hybrids (2015, background): “In some low-N input onditions both PostN and RemN were equally important to final rainN (Fonzo et al., 1982; Worku et al., 2007).”
Mechanisms of Nitrogen Use in Maize (2019, background): “Nitrogen accumulation in aboveground maize biomass typically increases as the N level in the soil increases [34], and aboveground biomass can be reduced if the soil N supply is insufficient for crop demand [35].”
Statistical Analysis of Yield Trials by AMMI and GGE: Further Considerations (2008, background): “Consequently, they contribute largely or even mostly to GE rather than to G. For instance, see Ludlow and Muchow (1990) and Wright and Rachaputi (2004) regarding drought tolerance and Worku et al. (2007) regarding nitrogen response.”
