zResults expressed as percentage for macronutrients (N,
P, K, Ca, Mg) and ppm for micronutrients (Fe, Mn, Cu, Zn).
yThe control was not topdressed with additional
fertilizer, however did receive the normal nursery practice of twice
weekly fertilizer-injected irrigation water.
xTreatments analyzed using mean separation. Column
means with the same letter are not different based on P = 0.05 using
least significant difference (LSD).
