Avaliação de kit de irrigação por gotejamento utilizando água residuária

Abstract

Agricultural productivity in irrigated systems is directly related to the uniformity of distribution of water to the plants. The periodical evaluation of this water distribution is fundamental, since an irregularity in this parameter may waste water and energy, as well as undermine the profitability of the property. In this way, the purpose of this work is to compare the water application efficiency of the drip kit-Dripkit after 15 months of use in the field, operating with treated wastewater. The test was carried out in the Hydraulic Laboratory of the Department of Rural Engineering of the Faculty of Agronomic Sciences-FCA/UNESP, Campus Botucatu-SP and was conducted in accordance with the ISO 9261: 2004 standards, using potable water. The evaluation was performed on a test bench for dripping irrigation and the uniformity, Christiansen, distribution and statistical coefficients were calculated. The CUC, CUD, CUE and EA parameters were classified as bad, regular, unacceptable and unacceptable, respectively.
