Micronutrient-efficient genotypes for crop yield and nutritional quality in sustainable agriculture. A review (2011, background): “Nutrient efficiency emphasizing utilization is generally defined as total plant biomass produced per unit nutrient absorbed, which is equivalent to the reciprocal of the nutrient concentration of the entire plant (Gourley et al., 1994).”
Accumulation and Translocation of Nitrogen in Spring Cereal Cultivars Differing in Nitrogen Use Efficiency (2007, background): “Alternatively BPE, as a measure of total plant biomass produced per unit N absorbed, also demonstrates N concentration in the entire plant and describes the internal N requirement in many agronomically important species ( Gourley et al., 1994 ).”
Zinc nutrition in wheat-based cropping systems (2017, background): “Plant factors affecting Zn uptake The selection of Zn-efficient wheat genotypes that can grow well on soils with low Zn content is a sustainable and efficient way to overcome Zn deficiency and will reduce fertilizer use (Gourley et al., 1994).”
Detection of quantitative trait loci for phosphorus deficiency tolerance at soybean seedling stage (2009, methodology): “The P acquisition efficiency (PAE) was calculated as the total amount of phosphorus in the plant (mg phosphorus/ plant) and P use efficiency (PUE) was calculated as the plant dry weight produced per unit of phosphorus (g dry weight/mg phosphorus) (Gourley et al. 1994).”
Genotypic variation in common bean in response to zinc deficiency in calcareous soil (2004, methodology): “…variation in tolerance to Zn deficiency (Rengel and Graham, 1995a; Cakmak et al., 1997; Khan et al., 1998; Torun et al., 2000; Rengel and Römheld, 2000) and also similar calculations have been used for assessing other nutrient deficiencies (Fageria and Baligar, 1999; Gourley et al., 1994).”
