Over four years the seasonal water use by Acala cotton on sandy soil averaged 25.6 inches under subsurface drip irrigation and 45.4 inches under furrow irrigation. Yield differences depended on soil quality. On a good, uniform sandy soil, there was little difference between drip and furrow irrigation, both averaging about 1658 lbs/ac of lint cotton. On a poor, highly variable sandy soil, the drip treatment averaged 1574 lbs/ac and the furrow treatment only 1355 lbs/ac.
