Physiological Evaluations of Maize Hybrids under Low Nitrogen

Table 2

Interaction between year and nitrogen on photosynthetic active radiation (par) and leaf area index at Tudun Wada and photosynthetic active radiation (par) and plant height at Zaria of maize-hybrids in 2014 and 2016.

Treatments	Tudun Wada				Zaria
Year			Nitrogen (Kg N ha^-1)
	0	120	0	120	0	120	0	120
	IPAR		Leaf area index		IPAR		Plant height
2014	0.23	0.28	2.19	2.77	0.38	0.59	82.80	176.30
2016	1.59	3.05	1.59	3.05	1.74	2.75	169.3	180.80
SED	0.083		0.271		0.055		4.765

Means followed by the same letter(s) within rows and columns are not significantly different using DMRT.
SED = standard error of a difference.
