Habanero chili crop is a source of income for producers on the Yucatan Peninsula. An experiment was set up in July 2017 by previously taking a soil sample of the plot, with a loamy clay texture, and applying three fertilization treatments: 56, 112 and 168 kg ha-1 of phosphorus, defined according to the management of the producers. The number and weight of the fruits and the yield were measured. In the end, we evaluate the initial and final soil and plant samples collected at each treatment on macro and micronutrient concentrations in roots, stems, leaves, and fruits. We found no significant effects of the treatments by the effect of increasing doses of phosphate fertilizers, the fruit yield ranging from 63.4 to 69.7 t ha-1. In this study, we applied the simplified conceptual model to estimate the fertilization dose that contributes to the sustainability of their management.
