Calibrating the leaf color chart for nitrogen management in different genotypes of rice and wheat in a systems perspective (2004, background): “Rice seedlings need portant than the contribution of N uptake after midtill- about 7 to 8 d to recover from transplanting shock ering when crop demand is greatest and reproductive ( Meelu and Gupta, 1980 ), and thus, N uptake within 2 Reproduced from Agronomy Journal.”
Improving Nitrogen Fertilization in Rice by Site-Specific N Management (2011, methodology): “Both the SPAD and leaf color chart provide a good estimation of leaf N content on a leaf-area basis (Peng et al., 1993; Yang et al., 2003 ).”
On-farm evaluation of leaf color chart for need-based nitrogen management in irrigated transplanted rice in northwestern India (2007, background): “Yang et al. (2000) have shown a linear relationship between an LCC reading and leaf N content.”
Need based nitrogen management using the chlorophyll meter and leaf colour chart in rice and wheat in South Asia: a review (2010, methodology): “Several workers (Peng et al. 1993; Murdock et al. 1997; Turner and Jund 1991; Yang et al. 2003; Janaki and Thiyagrajan 2004; Shukla et al. 2004) have reported significant coefficient of correlation among the grain yield and N content in ‘Y leaf’, as well as with SPAD values recorded at critical…”
Strategies for overcoming low agronomic nitrogen use efficiency in irrigated rice systems in China (2006, methodology): “The leaf N content is estimated non-destructively with a chlorophyll meter (SPAD) or leaf color chart (LCC) (Tao et al., 1990; Peng et al., 1996; Balasubramanian et al., 1999; Yang et al., 2003).”
LAI and chlorophyll estimation for a heterogeneous grassland using hyperspectral measurements (2008, background): “The ability to predict chlorophyll content from SPAD readings has been demonstrated in several studies (Dwyer et al., 1991; Markwell et al., 1995; Takebe et al., 1990; Vos and Bom, 1993; Yang et al., 2003).”
Leaf Colour Chart vis-a-vis Nitrogen Management in Different Rice Genotypes (2011, methodology): “LCC strategy calibrated with SPAD determines the real time for efficient management of N [26].”
