Abstract/Contents:"Persisting drought conditions in California are limiting the amount of water that can be allocated to irrigate golf courses. Some chemicals, such as Plant Growth Regulators (PGR), and wetting agents have been shown to help sustain bermudagrass quality under deficit irrigation. A study was conducted at the University of California, Riverside to determine if Primo Maxx (trinexapac-ethyl), Revolution, and nitrogen (N) fertilization (6 different fertilizers: Gro-Power; SeaBlend (12-4-5)+ StressRX + XP Micro; Yara Liva (15.5-0-0); Turf Royale (21-7-14); Turf Royale (21-7-14) + experimental product ACA 1935; Turf Royale (21-7-14) + experimental product ACA 5000; compared at a rate of 20 g N m-2/year) could reduce water use and enhance quality of bermudagrass 'Princess 77' irrigated at either 70% or 40% reference evapotranspiration (ETos) under fairway conditions. Product and irrigation treatments were applied from May thru October 2016 and 2017. Every two weeks, plots were evaluated for turf quality, Naturalized Difference Vegetation Index (NDVI), soil volumetric water content (VWC) using time domain reflectometry (TDR), and dark green color index (DGCI) as well as percent green cover using Digital Image Analysis (DIA). At 70% ETos replacement, turf quality was highest in plots that received Primo Maxx and Revolution. Although no differences were found among fertilizer treatments, fertilizer alone was able to sustain bermudagrass quality at a minimum acceptable level at 70% ETos. Revolution had the greatest positive effect on turf under severe deficit irrigation (40% ETos), whereas Primo Maxx did not improve quality under more severe deficit irrigation. Experimental products ACA 1935 and 5000 improved bermudagrass quality under severe deficit irrigation toward the end of 2016 and throughout 2017. Overall, results indicate that sufficient N fertilization combined with Revolution, and ACA experimental products or SeaBlend + StressRX + XP Micro biostimulants can sustain bermudagrass quality under severe deficit irrigation."
