| description | Sap analysis is a nutritional diagnostic tool to provide timely fertilization adjustments in crops. The objective of this study was to determine the reference levels of NO3 - and K+ in sap per phenological stage. The study evaluated the proper use of this nutritional diagnostic tool for N and K in Diacol Capiro and Pastusa Suprema potato on the Bogotá Plateau at 55, 75, 100, 125 and 150 days after sowing (das) in response to balanced fertilizer levels (0; 1,450; 1,900 and 2,375 kg ha-1) on the yield, dry matter and harvest index to determine levels for cultivation and phenology. The highest K+ concentration in sap in the stems occurred at the vegetative stage with 4,800-5,000 mg L-1, decreasing in tuberization with 2,725 mg L-1, without significant differences between cultivars; contrary to the behavior of N-NO3 - in the stems, where the maximum concentration at tuberization was 2,466 mg L-1 Capiro and 2,200 mg L-1 Supreme, with decreased values at physiological maturity. The reference levels were obtained at flowering stage for Capiro by quadratic adjustment of N-NO3 - and K+ in sap with 3,280 mg L-1 and 1,231 mg L-1, respectively, and related with the response to fertilization, yield, dry matter, and leaf area. In contrast for Supreme, the evaluated N, with levels higher than 1,250 mg N-NO3 - L-1 in sap, supposed luxury consumption. Using this diagnostic tool in the field, adjustments can be made to the management of nitrogen and potassium nutrition of these cultivars. |

El análisis de savia es una herramienta de diagnóstico nutricional para realizar ajustes oportunos de fertilización en cultivos hortícolas. El objetivo de este estudio fue determinar los niveles de referencia de NO3 - y K+ en savia por etapa fenológica y conocer el uso adecuado de esta herramienta de diagnóstico nutricional de N y K en cultivares de papa Diacol Capiro y Pastusa Suprema en la Sabana de Bogotá a los 55, 75, 100, 125 y 150 días después de siembra (dds) en respuesta a cuatro niveles de fertilizante (0, 1.450, 1.900 y 2.375 kg ha-1) y su efecto sobre rendimiento, materia seca e índice de cosecha. La mayor concentración de K+ en savia de tallos para los dos cultivares se presentó en etapa vegetativa con 4.800 a 5.000 mg L-1, disminuyendo hasta tuberización con 2.725 mg L-1, sin diferencias significativas entre cultivares; contrario al comportamiento de N-NO3 -, donde se presentó diferencias entre cultivares con una máxima concentración en tuberización con 2.466 mg L-1 en Capiro y 2.200 mg L-1 en Suprema con disminución en madurez fisiológica. Se obtuvieron niveles de referencia en etapa de floración para Capiro mediante ajuste cuadrático de N-NO3 - y K+ en savia con 3.280 mg L-1 y de 1.231 mg L-1, respectivamente las cuales se relacionan con la respuesta a la fertilización, rendimiento, materia seca y área foliar. En contraste, para Suprema el N evaluado en savia supone un consumo de lujo con niveles superiores a 1.250 mg N-NO3 - L-1. Con esta técnica diagnóstica en campo se puede establecer ajustes oportunos en el manejo de la nutrición vegetal nitrogenada y potásica de estos cultivares.
