Plant Growth and Nutritional Quality Attributes of Basella alba Applied with Variable Rates of Nitrogen Fertilizer at Different Planting Dates under Canadian Maritime Climatic Conditions

Table 4

Analysis of variance values for the main and interaction effects of planting time (PT), nitrogen (N) rate and total soil N, nitrate-N, and ammonium-N covariates on the number of branches, total yield, and leaf dry matter content (LDMC), total phenolic content (TPC), and total carotenoid content (TCC).

Source of variation	Total yield	LDMC	TPC	TCC	Nitrate content
PT	0.13	0.38	0.20	0.38	0.63
N rate	0.15	0.63	0.04	0.03	0.06
PT × N rate	0.08	0.01	0.04	0.02	0.22
Total soil N	0.96	0.28	0.87	0.88	0.57
Soil nitrate-N	0.86	0.44	0.55	0.33	0.72
Soil ammonium-N	0.20	0.92	0.70	0.55	0.66

values (/0.05–0.1) of significant and marginally significant effects that require multiple means comparison are shown in bold.
