Abstract/Contents:"The use of wetting agents has been proposed as a water conservation strategy for golf course management, however more research is needed to identify which wetting agents have greater potential for water conservation. Eleven wetting agent treatments were tested against an untreated control to determine their ability to reduce water use and enhance quality on 'Tifway II' hybrid bermudagrass irrigated at either 65%, 55% or 45% ETos in Riverside, CA under fairway conditions from May thru October 2018. Every two weeks, plots were evaluated for turf quality on a scale from 1 = worst to 9 = best, Normalized Difference Vegetation Index (NDVI) using a GreenSeeker instrument, volumetric soil water content (VWC) using time domain reflectometry (TDR), and dark green color index (DGCI) as well as percent cover using Digital Image Analysis (DIA). Double ring infiltrometer test was also run monthly from May until October to assess differences in speed of water infiltration among treatments. All treatments had a positive effect in comparison to control during the summer months. Results show that bermudagrass could sustain sufficient quality throughout the summer when irrigated as low as 55% ETos when a wetting agent was applied. As many as 8 wetting agent treatments were ranked in the top-performing group in August. Higher soil volumetric water content (VWC) or infiltration rate did not seem to result in better turf quality among wetting agent treatments. The study will be repeated in 2019 to further investigate wetting agent effects on soil water distribution uniformity and turf quality."
