Resumo: The determination of the amount of water needed for crops is one of the main parameters for correct irrigation planning. In this context the FAO Penman-Monteith method (FAO-PM) has been recommended as the best for the reference evapotranspiration (ETo) estimates. However it is not always possible to have all the necessary data for its application; in this case, alternative criteria must be used for this estimation. In this study, the objective was to estimate ETo by the FAO-PM method with only the maximum and minimum temperature values, here called Simplified FAO-PM, and compare it to the standard method (FAO-PM) with all input data, for Lavras, Minas Gerais State, Brazil. It was observed that the alternative method has the tendency to overestimate the standard method, however, this approach is feasible to estimate ETo for irrigation scheduling in localities where not all input data required for FAO-PM is available

En el presente, la ecuación de Penman-Monteith (FAO-PM) ha sido recomendada como la mejor para estimar la evapotranspiración de referencia (ETo). Sin embargo, no siempre es posible tener todos los datos necesarios para su aplicación, pudiendo en este caso adoptar criterios alternativos para el uso de la misma. Por lo tanto, el objetivo del estudio consistió en estimar ETo por la ecuación FAO-PM con solo los valores de las temperaturas máximas y mínimas, cambiando su nombre por la FAO PM Simplificado, y compararlo con el método estándar (FAO-PM) y con esta ecuación tenía todos los datos de entrada para Lavras, Minas Gerais, Brasil. Se observó que el método alternativo tiende a sobrestimar el método estándar, sin embargo, con la propuesta alternativa es posible estimar ETo para el riego en los lugares donde no siempre tienen la disponibilidad de todos los datos de entrada necesarios para la ecuación FAO-PMUniversidad de Tarapacá2017-06-05T11:34:59Z2017-06-05T11:34:59Z2013-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCARVALHO, L.
