Abstract

The effect of length of run and size of stream on moisture distribution in irrigated corn furrows was evaluated by three methods; namely, measurement of irrigation water flowing past three points in selected furrows, measurement of irrigation water added to soil as determined from soil samples, and measurement of variation in yield of corn produced on selected areas within the plot area.

This study was conducted on a small area of field number 4 located on the Frenchman-Cambridge Irrigation Development Farm, near Arapahoe, Nebraska.The soil is classified as Hall Silty Clay Loam. The experimental area was divided into six 525 feet long plots of six rows each. The irrigation water applied to each plot was metered from header boxes equipped with four calibrated orifices. Water was applied into the center four furrows of three plots at the rate of 6 gallons per minute and into the center four rows of three other plots at the rate of 10 gallons per minute.

The author made several conclusions based on the data gathered from the experiment including that the data obtained from soil samples appear to be the most reliable for evaluating the effect of size of stream and length of run on moisture distribution in irrigated corn furrows.
