In This work are presented the results obtained in the tecnique hidraulic evaluation of the emittter type dropfeeed model DRIPNET autocompensating made by the firm NETAFIM FROM Israel .The values reached by the variation coefficient (VC) varies between 1,2| % verifying that the quality of the emitter can be evaluated as good. The greater variations of the flow of the emitter occured when the charge reached valves higher to 20 mca and the lesser variations were present when the charge was only of 5 mca. This aspect was evidenced by the compensation level of the emitter studied. Besides, the hidroedaphologics characteristics of the different types of soils were studied in order to design these systems, determining the forms and dimensions of the wet bulb, obtaining a stabilization of the moisture diameter at 5,2 liters at 48 cm in red ferralitic. so the space of the emitter can guarentee a continuoos flow of moisture between bulbs of 10 %.determining the forms and dimensions of the wet bulb, obtaining a stabilization of the moisture diameter at 5,1 liters at 46 cm sandy and muddy. so the space of the emitter can guarentee a continuous flow of moisture between bulbs of 8 %. Finally, a study was performed in order to know the amount of water supplied to the soil by the emitter, obtaining good results due that this technology gives high efficiency with minimum consumption of water and energy, preserving in this way our environment and natural resources.Downloads
