| description | Nutrient uptake curves are essential in fertilization planning to achieve high yield and production quality. The research was carried out at the Santa Catalina Experimental Station (EESC) of the National Institute of Agricultural Research (INIAP - Ecuador). The research objective was to determine the nutrient absorption curves (N, P, K, Ca, Mg and S) in the production of pre-basic potato seed with different nutrient solutions under greenhouse conditions, evaluated in soil as the substrate and with seedlings obtained from cuttings of the Superchola variety. Five nutritional solutions were evaluated: The control (T1), Rational Method (T2), INIAP method (T3), Steiner method (T4) and Pilvicsa method (T5). These treatments were implemented in a completely randomized design. Variables evaluated were: total dry plant biomass, nutrient absorption (in four phenological stages) and yield. The highest amount of plant biomass was obtained with the nutritional solution T5 with 205.68 mg plant-1. The highest nutrient absorption of N, P, K, Ca, Mg and S of 4.4, 0.97, 8.25, 1.57, 0.52 and 0.55 g plant-1, respectively, were also obtained with the nutritional solution T5. The highest yield of 10.73 t ha-1 and 10.63 t ha-1 were obtained with the nutrient solutions of T5 and T4, respectively. The logistic model presented a determination coefficient of around 90%. In conclusion, the nutrient solution T5 (Pilvicsa) presented the highest plant biomass, nutrient uptake and yield. |

Las curvas de absorción de los nutrientes permiten elaborar planes de fertilización óptimos para alcanzar un mejor rendimiento y calidad de los tubérculos en papa. La investigación se desarrolló en la Estación Experimental Santa Catalina (EESC) del Instituto Nacional de Investigaciones Agropecuarias (INIAP - Ecuador). El objetivo fue determinar las curvas de absorción de los nutrientes (N, P, K, Ca, Mg y S) en la producción de semilla de papa prebásica con diferentes soluciones nutritivas en condiciones de invernadero, en suelo como sustrato y con plántulas provenientes de esquejes de la variedad Superchola. Se estudiaron cinco soluciones nutritivas: Testigo (T1), Método Racional (T2), INIAP (T3), Steiner (T4) y Pilvicsa (T5). Se utilizó un diseño completamente al azar. Se evaluó la biomasa seca total, absorción de nutrientes (cuatro etapas fenológicas) y rendimiento. Los resultados principales mostraron que: i) la mayor cantidad de biomasa se obtuvo en T5 con 205.68 g planta-1; ii) la absorción de nutrientes en T5 presentó los mayores valores de N, P, K, Ca, Mg y S, con 4.4, 0.97, 8.25, 1.57, 0.52 y 0.55 g planta-1, respectivamente; iii) T5 presentó un rendimiento de 10.73 t ha-1 y T4, 10.63 t ha-1, y iv) el modelo logístico utilizado presentó coeficientes de determinación del 90%. En conclusión, el tratamiento T5 (Pilvicsa) presentó mejores resultados en biomasa, absorción de nutrientes y rendimiento.
