Con un área de riego de aproximadamente 710.6 mil ha, se calcula un consumo anual de 1928 GWh en los sistemas de riego por pivote central instalados en Brasil. Considerando la necesidad de reducir los costos de producción, en este trabajo se estratifican las energías en pivotes centrales y se proponen indicadores que asocian la eficiencia energética a la hídrica y permiten comparar los sistemas de riego en condiciones topográficas diferentes. Estos indicadores fueron aplicados a tres sistemas de riego donde se verificó consumos específicos normalizados, variando entre 12.89 y 31.24 kWh mm ¹ ha(-1)10-2 m-1, y eficiencias de riego entre 8.7% y 21.1%.
With an irrigated area of approximately 710.6 thousand ha, an annual consumption of 1928 GWh is calculated in the systems of center pivot irrigation installed in Brazil. Considering the need to reduce production costs in this paper, the energies are stratified in center pivot and indicators are proposed that associate energetic efficiency to hydric efficiency and make it possible to compare the irrigation systems under different topographic conditions. These indicators were applied to three irrigation systems where normalized specific consumptions were verified, varying between 12.89 and 31.24 kWh mm-1 ha-1 10-1 m-1, and irrigation efficiencies between 8.7% and 21.1%.
