Means and standard errors per cultivar are the average at both fertilizer doses; means and standard errors per dose are the average for all cultivars. Means followed by the same letter within a column are not significantly different between cultivars or between doses according to Tukey’s test at . Mean data only for moderate fertilizer dose
