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).
