• Improvement of nitrogen management in rice paddy fields using chlorophyll meter (SPAD) (2008, background): “…location, radiation, soil fertility, biotic and abiotic stresses) that have been reported to confound meter calibration for N content estimation in rice and many plant species (Takebe and Yoneyama 1989; Peng et al. 1993; Campbell et al. 1990; Smeal and Zhang 1994; Balasubramanian et al. 2000).”
• Recommendations for nitrogen fertiliser topdressing rates in rice using canopy reflectance spectra (2008, unknown): “Grain yield and NUE were associated with not only the total N rate but also the timing of N application.”
• Need based nitrogen management using the chlorophyll meter and leaf colour chart in rice and wheat in South Asia: a review (2010, background): “Different threshold SPAD values may have to be used for different varietal groups as well (Balasubramanian et al. 2000; Huang et al. 2008).”
• Strategies for overcoming low agronomic nitrogen use efficiency in irrigated rice systems in China (2006, background): “Evaluation of RTNM in Asia has generally shown that the same rice yield could be achieved with about 20–30% less N fertilizer applied, but increases in yield were seldom (Peng et al., 1996; Balasubramanian et al., 1999, 2000; Hussain et al., 2000; Singh et al., 2002).”
• The Potential of a Chlorophyll Content SPAD Meter to Quantify Nutrient Stress in Foliar Tissue of Sycamore (Acer pseudoplatanus), English Oak (Quercus robur), and European Beech (Fagus sylvatica) (2008, background): “Consequently, chlorophyll content meters are widely used ©2008 International Society of Arboriculture to detect N deficiencies and subsequently improve N management within the agricultural industry (Peterson et al. 1993; Smeal and Zhang 1994; Balasubramanian et al. 2000).”
• Photosynthetic pigments, nitrogen, chlorophyll a fluorescence and SPAD-502 readings in coffee leaves (2005, methodology): “Since the chlorophyll meter has the potential to detect N deficiencies, it also shows promise as a tool for improving N management (Peterson et al., 1993; Smeal and Zhang, 1994; Balasubramanian et al., 2000).”
• Productivity and sustainability of the rice-wheat cropping system in the indo-gangetic plains of the Indian subcontinent: Problems, opportunities, and strategies (2012, background): “The use of a chlorophyll meter and leaf color chart is being advocated to apply the required amount of N (Balasubramanian et al., 1999; Balasubramanian et al., 2000; Peng et al., 1996; Turner and Jund, 1991).”
