<![CDATA[A perforated irrigation system composed of a network of perforated pipes through which water is pumped under pressure is expected to exhibit a specific flow pattern as its length is increased. This effect is also estimated on the magnitude of irrigation flow at each perforation along the pipe. Therefore, this phenomenon needs to be studied to achieve even irrigation distribution. The magnitude of differences in irrigation yields and the magnitude of irrigation that occur, along with the regression relationship between parameters, also need to be understood so that the perforated pipe design can provide flow according to application requirements. The study aimed to determine the regression relationship between test parameters of a perforation network using three ½" diameter pipes, with a pipe spacing of 100 cm and a perforation hole spacing of 0.6 m. Data analysis included irrigation yields, irrigation deviations, and variations in perforation pipe length. The results were presented in tables and graphs, and regression graphs were discussed and conclusions drawn descriptively. The results showed that increasing the length of the perforation pipe resulted in a smaller irrigation flow, resulting in smaller yield differences. Irrigation flow was irregular, and several polynomial linear regression relationships were found at P3 with R values ranging from 0.6 to 0.9 at a pipe length of 600 cm]]>
