TABLE 1.

Phenotypic traits, light extinction coefficient and fraction of intercepted PAR (fIPAR) of maize canopy for different treatments.

Treatment	Plant height (cm)	Leaf number	Leaf area per plant (cm2)	LAI	k	fIPAR
XY4.5	296.4 ± 3.43a	20.6 ± 0.25ab	9236.9 ± 313.5a	4.16 ± 0.14c	0.72	0.95
XY7.5	299.1 ± 9.16a	20.8 ± 0.48ab	8421.7 ± 397.3a	6.32 ± 0.30b	0.62	0.98
XY10.5	298.6 ± 9.67a	20.0 ± 0.00b	6977.6 ± 267.9b	7.33 ± 0.28a	0.70	0.99
ZD7.5	255.7 ± 5.63b	21.0 ± 0.00a	9281.4 ± 235.2a	6.96 ± 0.18ab	0.49	0.97

The absence of shared letters between treatments indicates the significant difference at the level of 0.05.
