This paper compares the widely used three irrigation systems, viz., drip, sprinkler and furrow, using the data observed in a laboratory farm located in the semi-arid region of Kenya. For these irrigation systems, the total irrigation requirements were 479.50, 610.55 and 783.50 respectively, but with same 428.95 mm of net irrigation requirement (NIR). The respective application efficiencies for the three systems were 89.72%, 70.31 and 54.54% indicating the drip irrigation system to be more efficient than the others in this study.
