DETERMINAÇÃO DO VALOR GASTO COM APLICAÇÃO DE ÁGUA EM UM SISTEMA DE IRRIGAÇÃO

Abstract

In the agricultural productive sector, irrigation is one of the most energyconsuming practices. Several factors contribute to this high consumption, from the large volumes of water applied to the fact that irrigation projects in Brazil, in general, require large engines. This is due to the location of water sources (rivers, dams and dams), almost always at the lowest part of the properties, which generates a high energy consumption. The costs generated in agricultural production will directly affect the producer's gains, so the choice of the appropriate tariff modality to the consumption profile is one of the measures that contributes to cost reduction, since the concessionaires present different tariffs according to the selected profile. The results show that the use of electric motors has lower cost to irrigate the selected area. However, combustion engines can become an important option in reducing energy costs, especially when rush hour consumption occurs.
