Evaluation of Irrigation Interval on High Plains Cotton Production With LEPA Systems

James P. Bordovsky and William M. Lyle


Two experiments were conducted in the Texas High Plains to determine the effect of irrigation interval with Low Energy Precision Application (LEPA) on cotton lint yield at several levels of water availability. High frequency, light irrigations are required by LEPA to maintain dikes and prevent runoff. Results show LEPA irrigation at intervals down to 2 days did not reduce yield as one might expect in a high evaporative environment. Rather, 2 and 3-day intervals were beneficial in the production of cotton lint particularly at very deficit levels of irrigation.
