Culture in open ground under net greenhouse with drip system.
Just after transplant plants were watered by flood irrigation. Next watering (by drip irrigation) took place three weeks after transplant; subsequent waterings (by drip irrigation) were made according to the needs of the plants. weeds were removed manually and phytosanitary treatments were made when needed.
