El objetivo de este trabajo fue evaluar el uso de información espectral para estimar el estado nutricional de Solanum tuberosum L, variedad Bacatá bajo diferentes niveles de fertilización, para esto se realizó un ensayo en un lote comercial de papa en Soacha, Cundinamarca, Colombia. Se estableció un diseño en medidas repetidas para un arreglo en bloques generalizados y al azar usando los tiempos como factor intra-sujetos, con ocho tratamientos con variación en nitrógeno (N) y potasio (K). Se evaluó la respuesta híperespectral entre los 350 a 2500nm con un sensor FieldSpec Standar-Res ® y se tomaron fotografías con una cámara multiespectral Micasense Red-edge M ®. Las variables nutricionales se midieron con sensores de ion selectivo Laqua ® y clorofilometro SPAD. Las mediciones se llevaron a cabo entre los 65 y 107 DDS. Se encontró que hubo efecto de los tratamientos y la época en la respuesta espectral de las plantas de papa por los cambios en la concentración de pigmentos, ya que hubo efecto de los tratamientos sobre el contenido de nitratos y en los valores SPAD. Sin embargo, no hubo efecto sobre el contenido de K en peciolos. Los índices de vegetación obtenidos con el sensor híperespectral que se basaron en la reflectancia de la región entre los 445 y 850 nm fueron los que más correlación obtuvieron con el contenido de nitratos y unidades SPAD. En las imágenes multiespectrales se registró la reflectancia más alta en las regiones del Red-Edge y NIR con las dosis más altas de fertilizante nitrogenado, además se encontró que los índices PSSRa, PSSRc y DATT-4 fueron los más sensibles a los cambios generados por la época de medición y los tratamientos evaluados, lo que los convierte en parámetros con potencial en la estimación del estado nutricional para la variedad Bacatá (Texto tomado de la fuente).The rational use of fertilizers is a measure that seeks the sustainability of the potato production system in Colombia, since this can reduce the environmental effect and the costs associated with the fertilization of the crop. The objective of this work was to evaluate the use of spectral information to estimate the nutritional status of Solanum tuberosum L, variety Bacatá under different levels of fertilization, for this a trial was carried out in a commercial potato lot in Soacha, Cundinamarca, Colombia. A repeated measures design was established for a generalized and randomized block arrangement using times as an intra-subjects factor, with eight treatments with variation in nitrogen (N) and potassium (K). The hyperspectral response between 350 to 2500nm was evaluated with a FieldSpec Standard-Res ® sensor and photographs were taken with a Micasense Red-edge M ® multispectral camera. Nutritional variables were measured with Laqua ® selective ion sensors and SPAD chlorophyllometer. Measurements were carried out between 65 and 107 DAS. It was found that there was an effect of the treatments and the season on the spectral response of the potato plants due to changes in the concentration of pigments, since there was an effect of the treatments on the nitrate content and on the SPAD values. However, there was no effect on the K content in petioles. The vegetation indices obtained with the hyperspectral sensor that were based on the reflectance of the region between 445 and 850 nm were the ones that obtained the most correlation with the content of nitrates and SPAD units. In the multispectral images, the highest reflectance was recorded in the Red-Edge and NIR regions with the highest doses of nitrogen fertilizer, and it was also found that the PSSRa, PSSRc and DATT-4 indices were the most sensitive to the changes generated by the time of measurement and the treatments evaluated, which makes them parameters with potential in estimating the nutritional status for the Bacatá variety.MaestríaMagíster en GeomáticaEl estudio se llevó a cabo en un lote comercial de papa para industria en el municipio de Soacha (Cundinamarca), con coordenadas 4° 37’ 00” N y 74° 15’ 60” W, a una altura sobre el nivel del mar de 2630 m, la pendiente promedio del lote experimental era del 13%.
