[automatically translated] In order to expand this crop and to improve quality bulbs to the carried out studies was to evaluate different fertilization techniques. Four fertilization formulas were Evaluated: 1) mineral fertilization commonly used by producers Paceco - pre-planting with 55, 110 and 80 kg ha-1 of N, P2O5 and K2O - after planting with 47 and 46 kg ha-1 of N and K2O ; 2) organic fertilization with an organic mix - pre-planting with 320 and 240 kg ha-1 of N and P2O5; 3) mineral fertilization - pre-planting with 40, 70 and 100 kg ha-1 of N, P2O5 and K2O - post-planting with 80 kg ha-1 of N half at 3-4 leaves and bulbs formation at half; 4) only post-planting fertilization with 52 and 184 kg ha-1 of N and K2O, half at 3-4 at half leaves and bulbs formation. Post-planting fertilization results in a yield reduction and a lower quality.
