Se utilizó un diseño completamente al azar, con seis tratamientos de diferentes dosis de nitrógeno y potasio. Se efectuaron 3 muestreos, para cada uno se muestrearon siete palmas por tratamiento para un total de 42 palmas por muestreo y de cada palma se analizaron los datos de 6 foliolos. En cada uno de los muestreos se tomaron fotografías aéreas con UAV y una cámara multiespectral MicaSense de 5 bandas (rojo, azul, verde, RedEdge y NIR); se realizaron análisis de contenidos foliares en laboratorio; se midió la reflectancia de 6 foliolos por palma con el espectroradiómetro FieldSpect4 y para el segundo muestreo se realizó un análisis edáfico. Se encontró que, a menor contenido de nitrógeno foliar, la reflectancia en el rango visible fue mayor; por otra parte, las mediciones de la reflectancia con el espectroradiómetro para el primer muestreo tuvieron la mayor cantidad de índices con correlaciones significativas para el nitrógeno foliar, destacando el índice de vegetación Datt, como el de mejor desempeño en estas pruebas. Para potasio y fósforo foliar, en ninguno de los tres muestreos se presentó correlaciones mayores a 0.5 entre los índices espectrales y la concentración de potasio y fósforo foliar. Para la construcción de los modelos PLSR la longitud de onda de mayor influencia, fue cercana a los 718 nm, donde el modelo generado para nitrógeno puede ser usado para realizar predicciones cuantitativas. Por otra parte, se encontró que las correlaciones para los índices espectrales y el contenido de Nitrógeno a partir de las fotografías aéreas fueron mejores que las obtenidas a partir de las mediciones de reflectancia con el espectroradiómetro para los tres muestreos. (Texto tomado de la fuente)The present investigation was carried out in the Guaicaramo plantation located in the municipality of Cabuyaro department of Meta, with the objective of determining the relationship between the spectral responses and the nitrogen and potassium content in the oil palm cultivation (Hybrid OxG, Coarí x LaMé) for non-destructive nutritional diagnostic purposes. For the above, a completely randomized design was used, with six treatments of different doses of nitrogen and potassium. 3 samplings were carried out, for each one seven palms were sampled per treatment for a total of 42 palms per sample and from each palm the data of 6 leaflets were analyzed. In each of the samplings aerial photographs were taken with UAV integrating the MicaSense multispectral camera with 5 bands (red, blue, green, RedEdge and NIR); leaf content analyzes were carried out in the laboratory; The reflectance of 6 leaflets was measured with the FieldSpect4 spectroradiometer; edaphic analysis where done for the second sampling. It was found that for a lower nitrogen content, the reflectance was greater in the visible range; Based on the reflectance measurements with the spectroradiometer, for the first sampling the highest number of indices with significant correlations for foliar nitrogen were obtained, highlighting the Datt vegetation index, as the one with the best performance in these tests; for potassium and foliar phosphorus, in none of the three samplings there were correlations greater than 0.5 between the spectral indices from reflectance measurements with the spectroradiometer and the concentration of potassium and foliar phosphorus; for the construction of the PLSR models, the wavelength of greatest influence is close to 718 nm, where the model generated for nitrogen can make quantitative predictions; It was found that the correlations for the spectral indices and the Nitrogen content from the aerial photographs were better than those obtained from the reflectance measurements with the spectroradiometer for the three samplings.MaestríaMagíster en GeomáticaGeoinformación para el uso sostenible de los recursos naturalesxv, 215 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ciencias Agrarias - Maestría en GeomáticaDepartamento de AgronomíaFacultad de Ciencias AgrariasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá630 - Agricultura y tecnologías relacionadas::633 - Cultivos de campo y de plantaciónElaeis guineensisRadiómetrosPalma de aceiteNitrógenoPotasioÍndices espectralesPLSRUAVEspectrorradiómetroOil palmNitrogenPotassiumSpectral indicesPLSRUAVspectroradiometerRelación entre las respuestas espectrales y la fertilización con nitrógeno y potasio en el cultivo de palma de aceite (Híbrido OxG)Relationship between spectral responses and nitrogen and potassium fertilization in oil palm crop (OxG hybrid)Trabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMAhamed, T., Tian, L., Zhang, Y., & Ting, K.
