This work was to create an assessment methodology of the global irrigation efficiency in systems with alfalfera valves. The purpose was to identify areas for improvement, from the time of extraction to the time of application to increase or maintain the potential efficiency of the system, and the optimal electromechanical efficiency of the pumping equipment. The methodology was based on the following procedure: 1) topographic survey of the area assessed, 2) water and soil sampling, 3) assessing the electromechanical efficiency, 4) gauging the irrigation system, 5)assessing the operation of the pond, and 6) evidence of irrigation progress per surface. An average value of global irrigation efficiency of 61.2 % was observed based on the evaluation of 1,792 hectares. An average value of 51 % was determined from a total of 58 pumps assessed regarding electromechanicalefficiency. These efficiencies can be increased by applying two improvement actions focusing mainly on monitoring land leveling and watering times according to the phenological stage of the crop. However, the training for the persons operating the irrigation systems is fundamental for these actions to be implemented properly. |
