Effect of Abiotic Stresses on the Nondestructive Estimation of Rice Leaf Nitrogen Concentration
Figure 2
Leaf N concentration based on dry weight versus (a) chlorophyll meter (SPAD) and (b) leaf color chart (LCC) values, both adjusted for specific leaf weight (SLW). Data from all samplings and treatments were used for the linear regression in (a) whereas value pairs from measurements at very early crop growth stages (31 DAS) in (b) were not included.
