Abstract

The research aimed to determine the pattern of wetting, duration of irrigation, spacing, and H/V ratio values at each lateral inlet pressure. The research was conducted in July 2018 to December 2018. This research was analyzed using descriptive methods with presentation of data in the form of tables and graphs. The study was conducted with three pressure treatments, 3 psi, 4 psi, and 5 psi. The data observed in this research were bulk density (g/cm³), soil porosity, wetting distance (cm), initial content of ground water, average emitter discharge, coefficient of discharge uniformity (cu). The observed parameters in this research were the average horizontal wetting distance at the right of the dripline (H1), the average horizontal wetting distance at the left of the dripline (H2), the average vertical wetting distance at the top of the dripline (V1), the average vertical wetting distance at the bottom of the dripline (V2), the ratio of the horizontal wetting distance to the vertical under the dripline (H/Vb), and the ratio of horizontal wetting to vertical over the dripline (H/Va). The results showed that increased pressure from 3 psi to 5 psi resulted at vertical wetting distance below the growing dripline. The horizontal wetting ratio of the vertical wetting distance under the dripline (H/Vb) was the best generated by a pressure of 3 psi, while the ratio of horizontal wetting to vertical above the dripline (H/Va) indicating the best treatment there were amounted 5 psi of pressure.
