Abstract
In two field trials conducted during one and two seasons, respectively, the effect of NPK fertilization on artichoke was studied. In experiment 1, the fertilizer treatments were: three dosages of each N, P and K; while in experiment 2, the treatments applied annually were: three dosages of N and two dosages of each P and K. There was no response on bolters yield with N dosage higher than 200 kg/ha/year. The PK fertilizer did not increase the yield in both experiments, showing that levels of available P from 27-33 ppm and of available K from 259-282 ppm were adequate for the normal growth of artichoke. No effect of N, P and K dosages on earliness of bolters was noted
