Shoot growth potential drives N uptake in maize plants and correlates with root growth in the soil (2010, background): “As the result, the root dry weight and even the root to shoot ratio at maturity is greater in the newer than in the older hybrid (Echarte et al., 2008).”
Mechanisms of Nitrogen Use in Maize (2019, background): “Nitrogen harvest index is greater in maize hybrids that sustain a high rate of photosynthesis during the grain-filling period, leading to greater NUE [118].”
A comprehensive study of plant density consequences on nitrogen uptake dynamics of maize plants from vegetative to reproductive stages (2011, background): “However, at supra-optimum plant densities, reductions in er-plant crop growth rate, N uptake rate, and partitioning of phoosynthetic products to the ear, and grain components, as well s increases in plant-to-plant variability (sometimes reflected via ore barrenness) lead to grain yield reductions re”
Mechanisms Involved in Soybean Rust-Induced Yield Reduction (2008, background): “Echarte et al. (2008) showed that N defi ciency reduced the absorption of incident PAR per unit leaf area because of lower chlorophyll content, but the eff ect of N on the photosynthetic effi ciency of absorbed radiation by the leaf was several-fold greater.”
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.”
Maize: Panacea for hunger in Nigeria (2015, background): “…development followed by (ii) period of more or less constant rate dry matter accumulation and (iii) a period of declining crop growth rate during the final phase of development when green leaf decline due to leaf senescence and leaf photosynthesis declines due to leaf aging (Echarte et al., 2008).”
Plant biomass and nitrogen partitioning changes between silking and maturity in newer versus older maize hybrids (2015, background): “The essential impact of leafDM and leafN to PostDM and PostN during grain filling has been attributed to the default role of leaf N as proteins in the photosynthesis process (Evan, 1989; Tsai et al., 1991; Echarte et al., 2008).”
