RESUMEN In the production costs of in the diploid potato var. Criolla Colombia, fertilizer represents 17% of the total costs, and it’s inappropriate and sometimes excessive use translates into expensive investments with technical inefficiency. This is mainly due to a lack of nutrient absorption levels of the selected variety. The research was conducted in Granada (Colombia) with five fertilization treatments (absolute control, commercial control, technical recommendation + 50%, technical recommendation and technical recommendation - 50%) arranged in a randomized complete block design with three replications. We evaluated dry matter, nutrient uptake, yield and specific gravity. The analysis showed that the most important elements were N, P, K, Ca, Mg, Zn, B and S, with higher absorption in the 113 days after planting (dap) with the commercial control, technical recommendation + 50% and technical recommendation, from highest to lowest. There were no statistically significant differ ences in yield for commercial control, technical recommendation + 50% and technical recommendation, but the economic analysis showed that the critical level of fertilization was found in commercial control. Un rubro representativo de los costos de produccion en la papa diploide var. Criolla Colombia, son los fertilizantes, cuya participacion corresponde al 17% de los costos totales. El uso inapropiado y en ocasiones excesivo de estos insumos se constituyen en inversiones onerosas, que conllevan ineficiencia tecnica. Lo anterior es consecuencia del desconocimiento de los niveles de absorcion de nutrientes de la variedad seleccionada. El ensayo se realizo en la vereda El Carrizal, Granada (Colombia), se utilizaron cinco tratamientos de fertilizacion (testigo absoluto, testigo comercial, recomendacion tecnica + 50%, recomendacion tecnica y recomendacion tecnica - 50%) dispuestos en un diseno de bloques completos al azar, con tres replicaciones. Se evaluo materia seca, absorcion de nutrientes, rendimiento y gravedad especifica. El analisis mostro que los elementos de mayor relevancia fueron N, P, K, Ca Mg, Zn, B y S, encontrando la mayor absorcion hacia los 113 dias despues de siembra (dds) con la recomendacion comercial, recomendacion tecnica + 50% y recomendacion tecnica, ordenados de mayor a menor. No se encontraron diferencias estadisticas significativas en rendimiento para la recomendacion comercial, recomendacion tecnica + 50% y recomendacion tecnica, pero el analisis economico mostro que el nivel critico de fertilizacion se encuentra con la recomendacion comercial.
