description AquaCrop is a model developed by the FAO Land and Water Division that simulates the growth of arable crops as a function of water consumption. It integrates the effect of edaphic and climatic variables, together with management variables, to represent production in response to water in the soil-plant system. In the present work, it was calibrated for alfalfa (Medicago sativa L.), using cutting data available from the INTA Rafaela cultivar network for the years 2000 to 2018, and the last four years corresponding to the cuts used in the validation. The model provided a good simulation of the accumulated aerial biomass in each cutting. The statistical tests that evaluated the calibration of the model. Their results were the coefficient of determination (R2) of 0.92; the root mean square error (RSME) with the value of 178 kg of DM ha-1; Nash efficiency coefficient (E) with values of 0.91; the normalised mean square error of 15% and the agreement index (d) with a value of 0.97 for each cut. The variables and parameters used in the validation showed an adequate level of accuracy. The accumulated aerial biomass shows a deviation that does not exceed ± 200 kg DM ha-1 comparing the simulated and measured values, so the model is able to reliably reproduce the analysed variable.

AquaCrop es un modelo desarrollado por la División de Tierra y Agua de la FAO que simula el crecimiento de cultivos herbáceos como una función del consumo de agua. Integra el efecto de las variables edáficas y climáticas, junto con las variables de manejo, para representar la producción en respuesta al agua en el sistema suelo-planta. En el presente trabajo fue calibrado para el cultivo de alfalfa (Medicago sativa L.), mediante el uso de datos de corte que se disponen de la Red de cultivares de la especie de INTA Rafaela, de los años 2000 a 2018, los cuatro últimos años corresponden a cortes utilizados en la validación. El modelo proporcionó una buena simulación de la biomasa aérea acumulada en cada corte. Las pruebas estadísticas que evaluaron la calibración del modelo, y sus resultados fueron: el coeficiente de determinación (R2) de 0,92; la raíz del error cuadrático medio (RSME) con el valor de 178 kg de MS ha-1; coeficiente de eficiencia de Nash (E) con valores de 0,91; el error cuadrático medio normalizado del 15% y el índice de acuerdo (d) con valor de 0,97 para cada corte. Las variables y parámetros utilizados en la validación, mostró un nivel de exactitud adecuado. La biomasa aérea acumulada muestra una desviación que no supera los ± 200 kg de MS ha-1 comparando los valores simulados y medidos, por lo cual el modelo es capaz de reproducir de forma confiable la variable analizada. AquaCrop é um modelo desenvolvido pela Divisão de Terra e Água da FAO que simula o crescimento das culturas arvenses em função do consumo de água. Integra o efeito de variáveis edáficas e climáticas, juntamente com variáveis de gestão, para representar o rendimento em resposta à água no sistema solo-planta. No presente trabalho foi calibrada para alfafa (Medicago sativa L.), utilizando dados de corte disponíveis na rede de cultivar INTA Rafaela para os anos 2000 a 2018, os últimos quatro anos correspondentes aos cortes utilizados na validação. O modelo forneceu uma boa simulação da biomassa aérea acumulada em cada corte. Os testes estatísticos que avaliaram a calibração do modelo, e os seus resultados foram: o coeficiente de determinação (R2) de 0,92; o erro quadrático médio de raiz (RSME) com o valor de 178 kg de DM ha-1; o coeficiente de eficiência de Nash (E) com valores de 0,91; o erro quadrático médio normalizado de 15% e o índice de concordância (d) com um valor de 0,97 para cada corte. As variáveis e parâmetros utilizados na validação mostraram um nível de precisão adequado. A biomassa aérea acumulada mostra um desvio que não excede ± 200 kg DM ha-1 comparando os valores simulados e medidos, pelo que o modelo é capaz de reproduzir de forma fiável a variável analisada.
