Resumo: Two furrow irrigation systems were compared, the first one consisting of application of a constant outflow through siphons, for R values equal to 0.26, 1 and 2. The second system consisted of use of runoff water for R values equal to 0.50, 1 and 2. When R value increased, in both the irrigation systems the losses by percolation decreased while the efficiencies of application and distribution increased, as well as the runoff losses. The irrigation efficiency increased with R value when the runoff water was used, occurring, however, the opposite when this water was not used. Complementary observations were made concerning to measurements of the fluctuation of the outlet disponible runoff during the irrigation of five consecutive sectors aiming at the dimension of irrigation systems with use of runoff water.

Um deles constou da aplicação de vazões constantes, através de sifões, para valores de R iguais a 0,26; 1 e 2. O outro constou da reutilização da água escoada para valores de R iguais a 0,5, 1 e 2. Observaram-se decréscimos nas perdas por percolação, enquanto as eficiências de aplicação e de distribuição aumentaram, o mesmo acontecendo com as perdas por escoamento em ambos os sistemas de irrigação, quando o valor de R aumentou. A eficiência de irrigação cresceu com o valor de R, quando se reutilizou a água de escoamento, ocorrendo o inverso quando não se reutilizou esta água. Foram feitas determinações quanto à flutuação da vazão de escoamento disponível durante a irrigação de cinco setores consecutivos, visando o dimensionamento de sistemas de irrigação com reutilização desta água.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSoares, José MonteiroBernardo, SalassierBrito, Ricardo A.
