“…• SWB models: data were used when there was evidence of model calibration and validation. Models considered included ISAREG (Pereira et al, 2003;Chaterlán et al, 2011), MOPECO (Domínguez et al, 2011;Martínez-Romero et al, 2019) and SIM-DualKc (Rosa et al, 2012;Paredes et al, 2018). The growth-yield model AquaCrop (Rinaldi et al, 2011) was also considered.…”

“…Five studies were also selected for onions. Two of them used weighing lysimeters (López-Urrea et al, 2009a;Piccinni et al, 2009), one used SWB with the model ISAREG (Chaterlán et al, 2011), another consisted of drainage lysimeters using neutron probes to perform the water balance (Bossie et al, 2009), and the last used a SWB supported by TDR (Carvalho et al, 2018). The latter study refers to harvesting onion green, and thus, K c end (std) was higher than those for dry onions, while they had similar K c mid (std) values.…”

“…There are four studies selected on garlic. One used eddy covariance for ET c act measurement (Villalobos et al, 2004) and another used the ISAREG model, as referred to before (Chaterlán et al, 2011). The study by Bryla et al (2010) reported on ET c act measured with weighing lysimeters while the last paper used remote sensing for deriving basal crop coefficients (Johnson and Trout, 2012).…”

“…Only two papers were selected for carrots (Chaterlán et al, 2011;Carvalho et al, 2016), which describe SWB applications for ET c act , the first using a gravimetric approach with the ISAREG model, and the second, a SWB application based on TDR observations, but without modeling. Both studies had similar K c mid (std) .…”

“…As previously pointed out, K cb end equals K cb mid because the broccoli was harvested before senescence. Cabbage crop coefficients are reported in a few papers but only two studies could be selected (Chaterlán et al, 2011;Zhang et al, 2011). Both performed a SWB, the first using a gravimetric approach along with the ISAREG model, and the latter using Watermark soil moisture sensors and a purposefully developed inverse modeling approach.…”

Many research papers on crop water requirements of vegetables have been produced since the publication of the FAO56 guidelines in 1998. A review of this literature has shown that determination of crop evapotranspiration (ET c ) using the K c -ET o approach, i.e., the product of the specific crop coefficient (K c ) by the reference evapotranspiration (ET o ), is the most widely-used method for irrigation water management. Consequently, a review was made to provide updated information on the K c values for these crops. The reviewed research provided various approaches to determine K c in its single and dual versions. With this purpose, actual crop ET (ET c act ) was determined with lysimeters, or by performing the soil water balance using measured soil water content and computational models, or by using Bowen ratio energy balance and eddy covariance measurements, or by using remote sensing applications. When determining the basal K c (K cb ), the partitioning of ET c act was evaluated using different approaches, though mainly using the FAO56 dual K c method. Since the accuracy of experimentally-determined K c and K cb values depends upon the procedure used to compute ET o , as well as accuracy in determining and partitioning of ET c act , the adequacy of the measurement requirements for each approach was carefully reviewed. The article discusses in detail the conceptual methodology relative to crop coefficients and the requirements for transferability, namely distinguishing between actual and standard K c and the need to appropriately use the FAO segmented K c curve. Hence, the research papers selected to update and consolidate mid-season and end-season standard K c and K cb were those that computed ET o with the FAO56 PM-ET o equation; and that also used accurate approaches to determine and partition ET c act for pristine, non-stressed cropping conditions. Under these experimental conditions, the reported K c and K cb values relative to the mid-and end-season could be considered as transferable standard K c and/or K cb values after adjustment to the standard climate adopted in FAO56, where average RH min = 45% and average u 2 = 2 m s −1 over the mid-season and late season growth stages. For each vegetable crop, these standard values were then compared with the FAO56 tabulated K c and K cb values to define the updated values tabulated in the current article. In addition, reported ancillary data, such as maximum root zone depth, maximum crop height, and soil water depletion fraction for no water stress, were also collected from selected papers and tabulated in comparison with those given for the crops in FAO56. The presentation of updated crop coefficient results is performed by grouping the vegetables differently than in FAO56, where distinction is made according to their edible parts:(1) roots, tubers, bulbs and stem vegetables; (2) leaves and flowers vegetables; (3) fruit and pod vegetables; and (4) herbs, spices and special crops, with most of them being newly introduced herein. The updated K c and K cb of veget...

El objetivo del trabajo fue calibrar y validar el modelo WinIsareg para soja en el litoral del Uruguay. El modelo estima las necesidades de agua de los cultivos bajo diferentes condiciones hídricas, mediante la simulación del balance hídrico (BH) de suelos. La información de suelo, cultivo, y clima, utilizada en la evaluación del modelo fue obtenida durante las temporadas 2011 y 2013. La evaluación consistió en ajustar los coeficientes de cultivo (Kc) y los factores de agotamiento de agua disponible sin estrés («p») para las fases de desarrollo (inicial, media y final) de soja, de forma tal de minimizar las diferencias entre los valores observados y simulados del contenido de agua del suelo. El Kc inicial ajustado fue 0,35, el Kc medio 1,18 y el Kc final 0,75. Los «p» ajustados fueron de 0,4 para las fases germinación y R1-R6 y de 0,6 para el resto del ciclo. Los Kc y «p» obtenidos permitieron lograr una elevada concordancia entre los valores simulados y observados del contenido hídrico del suelo para la calibración y la validación con diferentes situaciones de disponibilidad hídrica. El coeficiente de regresión (b) entre valores observados y simulados fue cercano a 1, las estimaciones del error absoluto (AAE) y raíz cuadrada media del error (RCME) fueron menores a 5 %, el coeficiente de Willmott «d» y la eficiencia (EF) cercanos a 1 y el coeficiente de determinación (R2) mayor a 0,8. El resultado de los indicadores estadísticos permite afirmar con certeza el buen funcionamiento del modelo WinIsareg en soja para el litoral del país.
