Introduction

? Irrigation water quantity and quality are becoming the limiting factors in maintaining high quality turf for sport fields and golf courses all around the world.

? Issues surrounding water quality and availability have led Turf Managers to blend water supplies from different sources, while others have had to rely on recycled water supplies.

Objectives

? Develop a protocol to optimize irrigation scheduling based on evapotranspiration (ET) demand.

? Reduce water usage by injecting wetting agents into the irrigation line.

? Monitor changes in turf quality.

? Analyze plant tissues to monitor any abnormal element accumulations.

? Measure crop coefficient (Kc) of the Bermuda grass maintained under fairway mowing conditions.

Materials and Methods

? Twenty four (3 m by 3 m) individually irrigated plots were laid out in a split-plot design.

? 12 plots receive potable water and 12 plots receive reclaimed water.

? Three surfactant treatments and a control were evaluated.

? Each treatment was evaluated under potable and reclaimed water with 3 replications.

? Water meters were installed on the lines to measure the amount of water used for irrigation.
