The materials used for fertigation were calcium nitrate(15.5N–0P–0K) and muriate potash (0N–0P–50K). There were fourfertigation events, one every two weeks starting at two weeks aftertransplanting. The proportion of N and K2O applied in each fertiga-tion event was equivalent to 8%, 15%, 20%, and 15% of the total Nand K2O applied to match the growth of the crop.
