• Optically assessed contents of leaf polyphenolics and chlorophyll as indicators of nitrogen deficiency in wheat (Triticum aestivum L.) (2005, background): “Agronomic practices for Chl generally consist of measurements at the middle of the very last or the two last fully developed leaves (Peng et al., 1996; Lopez-Bellido et al., 2004).”
• Nitrogen efficiency of wheat: Genotypic and environmental variation and prospects for improvement (2010, background): “The standard quality requirement for milling wheat in the UK is 13% protein in DM equivalent to 2.3% N in DM based on a conversion factor of 5.7 (Lopez-Bellido et al., 2004).”
• Identifying traits to improve the nitrogen economy of wheat: Recent advances and future prospects (2009, methodology): “The Minolta SPAD 502 CM measures light transmission in the red (650 nm) and near-infrared (940 nm) parts of the spectrum and has been used to estimate leaf chlorophyll content in maize (Blackmer et al., 1994) and to predict grain N requirements in wheat (López-Bellido et al., 2004).”
• The challenge of improving nitrogen use efficiency in crop plants: towards a more central role for genetic variability and quantitative genetics within integrated approaches. (2007, background): “However, its utilization is limited to certain varieties (Lopez-Bellido et al., 2004).”
• Relationship Between the Normalized SPAD Index and the Nitrogen Nutrition Index: Application to Durum Wheat (2006, methodology): “In conditions when N is the main limiting factor, SPAD values (absolute or index) have been used to predict grain yield (Fox et al., 1994; Vidal et al., 1999; Bavec and Bavec, 2001; Denuit et al., 2002; Lopez-Bellido et al., 2004).”
• Predicting Grain Yield and Protein Content in Winter Wheat at Different N Supply Levels Using Canopy Reflectance Spectra (2007, result): “Previous studies also found close relationships between GPC and leaf N concentration at anthesis, especially for the flag leaf (Wang, J. H. et al., 2003; Lopez-Bellido et al., 2004).”
