The trial was conducted during the months of January to August 2017, in the grounds of the Treasury. Yamile, located at km 27 of the Quevedo road - Santo Domingo de los Tsáchilas, province of Los Ríos. For the establishment of the experiment a completely randomized design was proposed with 6 treatments in three repetitions. The treatments studied were: 150% potassium fertilization, 100% potassium fertilization, Kelpak, Agrostemin, NBO and one control (fertilization plan of the farm). The main results showed that potassium fertilization at 150% produced more leaves at calving with 15.4, being the treatments of potassium fertilization at 100% and Agrostemín with which the plants arrived with a greater number of leaves at harvest with an average of 7.5 leaves, each one, confirming less foliage loss due to Black Sigatoka attacks. 100% potassium fertilization produced a greater number of total leaves with 30.3 leaves per plant, surpassing the absolute control in 3.2 leaves. The plan of 100% potassium fertilization produced a greater increase in the height and diameter of the pseudostem, in such a way that it showed taller and thicker calving plants with 4.27 m in height and 26.7 cm in diameter. The clusters showed a greater weight when applying the plan of potassium fertilization to 100% with 32.8 Kg, with an average of 8 hands per cluster, reflecting a productivity of 1.6 boxes per bunch, the latter being equal to those obtained with potassium fertilization 150% and Agrostemín.
