The purpose of this study was to compare the water application efficiencies of sprinkler and furrow irrigation under conditions such that the best possible efficiencies for each method were obtained. A determination also was made of the uniformity of water distribution by sprinkler and furrow irrigation.

Sprinkler and gravity irrigation were compared at the North Platte Agricultural Experiment Station of the University of Nebraska.The experimental plots were located in an area on the Northeast corner of the station, known as the Shelby land.The legal description of the area is the south 600 feet of the east ½ of the east ½ of the southeast ¼ of section 16, T 13 N, R 30 W.

The soil on the experimental area was a Bridgeport very fine sandy loam. Eight plots, 56 by 500 feet, were used in the experiment. Four plots of Midland milo were irrigated with a portable sprinkler line and four with gated pipe into furrows. All plots except two were separated from the neighboring plots by 30-foot strips of alfalfa

An adequate water supply was available at the plot area.Water was taken from a pipeline which taps the penstock of the Platte Valley Public Power and Irrigation District power plant. A six-inch aluminum pipe line was used to take water from the field riser to the experimental plots. The line was laid along the south ends of the plots.A “T” in the main line near the plots being irrigated allowed water to be delivered to a sprinkler lateral to the gated pipe at the same time.
