DRIP IRRIGATION SYSTEM WITH SOLAR PHOTOVOLTAIC ENERGY

Abstract

The verification of the uniformity of water application in localized irrigation systems is a tool that promotes its proper dimensioning, in order to result in the best crop yield. The objective of this work was to evaluate the performance of a dripping irrigation system operating under photovoltaic solar energy. The work consisted of the hydraulic dimensioning to find the ideal lengths of lateral lines that would allow less variation in flow due to pressure variations between 5 and 15 mca, followed by uniformity tests CUC, CUD and CUE in two situations (with and without system pressure calibration at the beginning of the area at 10 mca). It is concluded that when calibrating the service pressure at the beginning of the area at 10 mca, at any time of the day observed, the uniformity of water application was above 90%, which classifies the equipment as excellent for the line lengths from 30 to 60 meters.
