The study presents design details and field test results for a line source sprinkler plot irrigation system. The system delivers a uniform along‑plot, continuously variable across‑plot water pattern, allowing fertility gradients at right angles, with a small test area and water supply, though wind can limit application and all levels must use the same irrigation frequency.
Abstract The design details and a sample set of field test results for a line source sprinkler plot irrigation system are presented. The system produces a water application pattern which is uniform along the length of the plot and continuously, but uniformly variable across the plot. By applying a fertility variable along a plot (at right angles to the water variable) planted in some test crop, the system offers a convenient means for developing crop production function data. The system test area and water supply are both small. However, the application of the system may be limited by wind and all water application levels within a plot must be supplied at the same irrigation frequency.
