From February 2014 to May 2016 it was evaluated at the National University of Trujillo, the effect of increasing doses of NPK in dry matter accumulation, some morphological variables and yield on Ananas comusus (L.) Merr. Var. Roja Trujillana in flower pot and field. In flower pot used a completely randomized design with 4 treatments (0-0-0; 200-60-400, 300-80-500 and 400-100-600 mg/kg suelo NPK) and 4 replications, the data subjected analysis of variance and for mean separation Tukey test was used at the 5%, each experimental unit consisted a flower pot with 5 kg of acid soil Poroto planted with fruit hijuelo base of 132 g. It was found that (i) 150 days after planting , low doses (200- 60-400) and medium (300- 80-500) form the upper NPK group in total dry matter accumulation, root dry matter , root fresh matter, total fresh matter, number and length of root, and (ii) high dose (400-100...
