Macronutrients were applied to all plants via fertirrigation
beginning two months after transplanting, following similar
recommendations used by producers. The applied amount of each
compound was 20 kg ha-1 Ca (NO3)2, 24 kg ha-1 MgSO4, 80 kg ha-1
NH4H2PO4, 98 kg ha-1 H3PO4, 688 kg ha-1 urea and 797 kg ha-1
K2SO4 . The irrigation management was based on soil moisture
sensors installed at soil depths of 15 and 25 cm, the first
representing the soil depth from 5 to 15 cm, while the second band
of 15 to 25 cm aimed to determine the water storage in the soil,
thereby indicating how much irrigation was necessary.
