Resumo: | The objective of this work was to evaluate the limitations of a ten-day climatic water balance model to simulate irrigation in four different Paraná State regions. Sixty-eight water balance scenarios were tested to allow the relationship among crop evapotranspiration (Etc), probable precipitation at 75% level (P75%), soil available water capacity (AWC) and annual water deficiency (DEF). The results showed that: the model estimates its components better for greater values of available water (AW) in the soil; the ideal AWC value to process the irrigation analyses based on variations of ETo, Kc and Etc should be established in the model itself. However, if the condition "larger ten-day ETo ≤ AW" of the period is valid, the water balance produces consistent results for 10 days periodicity |

Nas análises, 68 cenários de simulação do balanço hídrico foram testados para permitir o relacionamento entre a evapotranspiração da cultura (ETc), chuva provável a 75%, diferentes capacidades de água disponível no solo (CAD) e deficiência hídrica anual (DEF). As análises realizadas mostraram que: o modelo consegue obter melhores estimativas de seus componentes para maiores valores de água disponível (AD) no solo; o valor ideal de CAD para processar as análises de irrigação em função das variações da ETo, Kc e ETc deve de preferência ser estabelecida no próprio modelo. Porém, se a condição “maior ETo decendial ≤ AD” do período for válida, o balanço hídrico apresenta resultados consistentes para periodicidade igual a 10 diasUniversidade Estadual de Maringá2008-04-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/172110.4025/actasciagron.v30i2.1721Acta Scientiarum.
