The experiment was carried out from May 2017 to July 2018 at the Manabí Polytechnic School "Manuel Félix López". Fertilization treatments were evaluated: (T1) conventional fertilization (220 N, 110 P2O5, 440 K2O), (T2) 50% chemical fertilization (110 N, 55 P2O5, 220 K2O) + 50% compost (3 t) ha-1), (T3) 25% chemical fertilization (55 N, 27 P2O5, 110 K2O) + 75% compost (4.5 t ha-1), (T4) 100% compost (6 t ha-1) and (T5) 50% chemical fertilization (110 N, 55 P2O5, 220 K2O). The data were subjected to analysis of variance and separation of means with the Tukey test at 5% of error probabilities. The main variable evaluated was yield in t ha-1. The results showed that the highest yield was obtained with conventional fertilization with 30.48 t ha-1 and the proportion of 50% of chemical fertilization + 50% of compost (3 t ha-1) with 27.22 t ha-1 , this in relation to the other treatments that achieved lower yields. Compost as a fertilizer was not an effective source to increase crop yield. However when combined with mineral fertilizers significantly increases the productivity of the crop. |
