Chlorophyll Meter’s Estimate of Weight-based Nitrogen Concentration in Rice Leaf is Influenced by Leaf Thickness
The chlorophyll meter (SPAD) has been widely used to measure the leaf N concentration. Nevertheless, linear regression equations of SPAD readings on N concentration (based on dry weight, Nw) differ with plant age and genotype mainly due to differences in specific leaf weight (SLW), and there is a cl...
