This work had the objective of to evaluate the application of inverter frequency drive on the electric and hydraulic parameters in the sprinkling irrigation system handling. Was used a water pump conventional system for sprinkling with 4 handled lines alternately, consisting the handling of the opening of 1, simultaneously 2, 3 and 4 lines and enrolling the electric energy consumption and the hydraulic parameters of the system. Later on, in the conventional system was coupled an starting system with variable rotation, composed by a pressure transducer and a inverter frequency drive, which acted varying the water pump rotation and adapting the preset pressure in relation to flow variation requested by the system. The found results allowed to evaluate that for the handling of 1, 2 and 3 lines simultaneously the system with inverter frequency drive, there was reduction of the electric energy consumption and the service pressure of the sprinkling was maintained, just varying the requested flow, according to the lines handling.

Keywords : irrigation handling; energy consumption; hydraulic parameters.
