Intra-specific competition in maize: Contribution of extreme plant hierarchies to grain yield, grain yield components and kernel composition (2006, background): “, 2000; Maddonni and Otegui, 2004), while KW is either not affected (Tetio-Kagho and Gardner, 1988) or is only slightly (5–30%) reduced (Edmeades and Daynard, 1979a; Echarte et al., 2000; Sangoi et al., 2002; Borrás et al., 2003).”
Row Width and Maize Grain Yield (2006, background): “…light environment with an enriched far-red radiation at the lowermost leaf stratum of crops at high plant population densities and narrow rows (Borrá s et al., 2003) increased the vertical profile of leaf N content (Chelle and Andrieu, 1999; Drouet and Bonhomme, 1999) and reduced the crop RUE…”
Physiology of maize I: A comprehensive and integrated view of nitrogen metabolism in a C4 plant (2005, background): “However, it is still unclear whether the nutritional status of the plant in terms of N availability or the photosynthetic activity in terms of carbohydrate synthesis and accumulation is the key factor triggering the onset of leaf senescence (Borras et al. 2003).”
Survey of Plant Density Tolerance in U.S. Maize Germplasm (2014, background): “Intraspecific competition at higher plant densities induces a gradual stress on the plant throughout the growing season that may alter plant growth (Borras et al., 2003).”
Grain Nitrogen Source Changes over Time in Maize: A Review (2013, background): “…the leaf senescence process is affected not only by N but also by water supply, light quality, and crowding stress, among other factors (Eik and Hanway, 1965; Pearson and Jacobs, 1987; Muchow and 370 www.crops.org crop science, vol. 53, march–april 2013 Carberry, 1989; Borrás et al., 2003).”
Genetic improvement in density and nitrogen stress tolerance traits over 38 years of commercial maize hybrid release. (2016, background): “Andrade et al. (1999) indicated that the number of kernels set per unit of PGR decreased at high densities and that higher densities therefore contributed to a lower final KNP. High density can also reduce KW due to a reduction in leaf area per plant (Borrás et al., 2003).”
