| description | The response of the citrus crop to environmental supply largely determines the speed and intensity of the plant's ecophysiological processes, which affect the development and production of the crop. The main objective was to analyze the effects of climatic conditions on the productivity of the ‘Valencia’ orange agroecosystems (Citrus sinensis L. Osbeck) previously typified in the department of Meta, Colombia. The climatological variables precipitation (PPT), maximum and minimum temperatures (Tmax and Tmin), wind speed, relative humidity and solar brightness were analyzed in an observation window spanning the years 2013 to 2015. Using the FAO CropWat model, the crop reference evapotranspiration (ETo) was obtained to applied agroclimatic indices. Using the statistical software STATGRAPHICS Centurion XVI v. 16.2.04, an empirical model was proposed that relates productivity according to agroclimatic indices, for the vegetative and reproductive phenological phases. It was found that the proposed empirical model explains 49% (P=0.0233) of the oscillation of productivity in study area agroecosystems. The model, based on agroclimatic indices associated with PPT, ETo, Tmax and Tmin, found that the relationship between productivity and agroclimatic indices is non-linear. It was established that productivity variation is mainly influenced by PPT, the occurrence and magnitude of which determines the volume of production and quality of the fruit. On the other hand, whereas increases in air temperature and the occurrence of water deficits in the pre-flowering and flowering phases positively favor crop production, the same factors produce a negative effect in the setting phase. |

La respuesta del cultivo de cítricos a la oferta ambiental determina en gran medida, la velocidad e intensidad de los procesos ecofisiológicos de la planta, que inciden en el desarrollo y producción del cultivo. Como objetivo principal se propuso analizar los efectos de las condiciones climáticas en la productividad de los agroecosistemas citrícolas de naranja ‘Valencia’ (Citrus sinensis (L.) Osbeck) previamente tipificados en el departamento del Meta-Colombia. En una ventana de observación (años 2013-2015) se analizaron las variables climatológicas precipitación (PPT), temperatura máxima (Tmáx) y mínima (Tmín), velocidad del viento, humedad relativa y brillo solar. Utilizando el modelo CropWat de FAO, se obtuvo la evapotranspiración de referencia del cultivo (ETo), aplicando índices agroclimáticos. Utilizando el software estadístico STATGRAPHICS Centurión XVI v 16.2.04, se propuso un modelo empírico que relaciona la productividad en función de índices agroclimáticos, para las fases fenológicas vegetativa y reproductiva. Se constató que el modelo empírico propuesto explica el 49% (P=0,0233) de la oscilación de la productividad en los agroecosistemas analizados en la zona de estudio en función de los índices agroclimáticos asociados con la PPT, ETo, Tmáx y Tmín, encontrando que dicha relación es de carácter no lineal. Se estableció que la variación de la productividad está principalmente influenciada por la PPT, cuya ocurrencia y magnitud determina el volúmen de la producción y calidad del fruto, en un segundo plano se encontró que los incrementos en la temperatura del aire y la ocurrencia de déficit hídricos en fase de pre-floración y floración favorecen positivamente la producción del cultivo, pero incrementos de la temperatura en la fase de cuajamiento afectan negativamente la producción.
