Indirect Estimations of Lentil Leaf and Plant N by SPAD Chlorophyll Meter

Table 3

Correlation coefficients of SCMR and adjusted SCMR (SCMR/SLW) with leaf N concentration (LNC), plant N concentration (plant N), and specific leaf N (SLN) for each growth stage of vegetative, first-pod, and late-pod and for the pooled data over the growth stages.

Growth stage	Variable	SCMR	LNC	Plant N%	SLN
Vegetative	SCMR	1.00	ns^†	ns	0.26
	Adjusted SCMR	0.58	0.35	0.36	−0.38
First-pod	SCMR	1.00	0.35	−0.19	0.37
	Adjusted SCMR	0.54	0.42	0.26	−0.37
Late-pod	SCMR	1.00	0.63	−0.43	0.65
	Adjusted SCMR	0.84	0.77	−0.40	0.40
Pooled	SCMR	1.00	0.50	ns	0.51
	Adjusted SCMR	0.70	0.75	0.40	ns

All coefficients are significant ( < 0.05), unless otherwise indicated (ns).
