Resumo: | The ISAREG model simulates the soil water balance. The performance of the model was evaluate in the condi ons of the Planalto Medio Region, in Rio Grande do Sul State (Brazil). Comparisons among soil water contents es mated by the water balance of the soil plant atmosphere system and observed data from tensiometers were performed, in order to validate the model for the Region. A perennial grass was used as reference crop for tes ng the model, while the soils and meteorological parameters were collected at the Embrapa Trigo Center, in Passo Fundo, RS (Brazil). The results showed a high poten al adherence among simulated and observed data, so indica ng an adequate performance of the model in those condi ons. According the sta s cal indicators obtained from regression analyses, the performance of the ISAREG model was considered as very good and it can be used for the water balance of the “Planalto Medio” Region (RS). |

Seu desempenho nas condiç es do Planalto Médio do Rio Grande do sul, foi avaliado através da comparaç o do conteúdo de umidade do solo, obido na simulaç o do balanço de água no sistema solorplantaratmosfera, com os dados medidos por tensiômetros visando validar seu uso para a Regi o. A avaliaç o do modelo foi de realizada uilizando como cultura de referência uma gramínea perene, adotando os parâmetros edáficos e agrometeorológicos da Embrapa Trigo, de Passo Fundo, RS. Os resultados mostraram o alto potencial de aderência do modelo. De acordo com os indicadores esta sicos obidos na avaliaç o, coeficiente de correlaç o, índice de concordância e de desempenho, o modelo foi classificado como muito bom e pode ser uilizado para simular o balanço hídrico na regi o do Planalto Médio do RS.Departamento de Diagnóstico e Pesquisa Agropecuária.
