Abstract/Contents:"Drought events are becoming more prevalent, and during limited water availability, ornamental plants are often the first to be placed under water use restrictions. There is no consistent information about irrigation frequency requirements for sustainable performance of most used warm-season turfgrass species. Thus, the objective of this study was to evaluate the performance under irrigation restrictions of bermudagrass (Cynodon Rich. species), St. Augustinegrass (Stenotaphrum secundatum (Walter) Kuntze), seashore paspalum (Paspalum vaginatum Swartz) and zoysiagrass (Zoysia Willd. species) commercial cultivars and breeding lines from the breeding programs at Oklahoma State University, University of Georgia, North Carolina State University, Texas A&M University and University of Florida. Field trials arranged as a split-plot design with three replications were conducted at research facilities at Citra (Florida) and College Station (Texas). However, the design had an extra casualization restriction (species) at Citra. The trials were conducted from 2016 to 2019, and from 2017 to 2020 at College Station and Citra, respectively. The irrigation frequencies were 0, 1, 2, 4 and 8 times per month. Additionally, a sensor-based irrigation treatment was evaluated only at Citra. The response variable evaluated was turfgrass quality (TQ, NTEP ratings from 1 to 9). The estimated TQ values for the 4 and 8 times per month treatments were statistically equal, being also equal to sensor-based treatment at Citra, and superior to other treatments. Across species, bermudagrass performed better than all other species at College Station, whereas at Citra bermudagrass and zoysiagrass were the top performers. In terms of specific genotype performance across treatments, DALSA1618 St. Augustinegrass performed better at Citra, while bermudagrass TifB16101, TifB16113 and OSU1337 were top-performance genotypes at College Station. Therefore, irrigating four times was more water efficient than eight times per month to get the greatest TQ performance, and also provided equal performance to sensor-based irrigation at Citra."
