↵^zLeaf N concentration data was only available for two cultivars, and thus statistical analysis of data for this element applies only to those two cultivars.
↵^yMean separation of cultivar main effects by Duncan’s LSD (0.05). Mean values having similar letters are not significantly different from each other.
↵^xAnalysis of variance for main effects (CV, SC) and interaction (CV*SC). NS = not significantly different; *, **, and *** indicate significance at P ≤ 0.05, P ≤ 0.01, and P ≤ 0.001, respectively.
