- Abstract
The statistical quality control tool, developed for the industrial sector, gained space in agriculture as an aid in the proper management of irrigation. The aim of the project was to assess, through the aid of statistical quality control, the uniformity of water distribution in drip irrigation units supplied by wastewater. The experiment was conducted in a controlled environment belonging to the Irrigation and Drainage Laboratory, of the Agricultural Engineering Academic Unit, Federal University of Campina Grande. Two types of lateral lines constituted of specific grippers were evaluated, submitted to different water sources, totaling 31 tests. Most of the values per test were within the control limits, however the flow values did not reach the manufacturer's catalog value for both drip strip models. The two models of emitters functioned during much of the study period within the control limits, the statistical quality control tool proved to be viable and essential, enabling the efficient use of the irrigation units.
