| Abstract/Contents: | "Accurate turfgrass crop coefficients are critical when scheduling irrigation based on reference evapotranspiration (ETo). Currently, locally derived turfgrass crop coefficients are lacking in the transition zone. The objective of this field study was to derive crop coefficients (Kc) for 'Triple Threat' tall fescue (Festuca arundinacea Schreb.) and 'Tifway' hybrid bermudagrass [Cynodon dactylon (L.) Pers. × Cynodon transvaalensis Burtt-Davy] managed in the transition zone. Direct measurements of actual evapotranspiration (ETa) were made through the weighing of lysimeters planted with tall fescue and hybrid bermudagrass. Data were collected from May through October of 2017 and 2018 from nonstressed turfgrass. Turfgrass crop coefficients were computed by the quotient of ETa and ETo, calculated from the ASCE-Standardized reference evapotranspiration equation using meteorological data collected from an on-site weather station. Tall fescue and hybrid bermudagrass Kc varied by month (P < 0.0001). Means for tall fescue and hybrid bermudagrass Kc ranged from 0.69 to 0.85 ( ± 0.16 SD) and 0.44 to 0.59 ( ± 0.10 SD), respectively. Tall fescue Kc exceeded hybrid bermudagrass every month as the result of higher ETa. The use of locally-derived turfgrass crop coefficients can assist turfgrass managers in the transition zone to better meet turfgrass water demands." |
