flowering stage): deficit irrigated based on 50% evapotranspiration (ET) and fully irrigated based on 100% ET. The required irrigation was determined following the potential ET (ET 0 ) and crop coefficient of watermelon (K c initial = 0.4, K c mid = 1

explain observations noted decades earlier in rhododendron nursery production. The objectives of this research were to verify theoretical reductions in plant evapotranspiration with increases in canopy closure and to begin defining the depth of the upper

evapotranspiration (ET c ) from weather data collected by the University of Georgia Weather Network weather station in Tifton. These data were used to calculate ET o from air temperature, solar radiation, wind speed, and relative humidity using the Penman

and Florida are based on variations of the WB method ( Harrison, 2009 ). The WB method estimates daily crop water use based on historic evapotranspiration (ET o ) values for a region adjusted with a crop coefficient (K c ) ( Allen et al., 1998

calculated based on ETc where ETc = ETr × Kc with ETr (Penman-Monteith reference evapotranspiration) ( Allen et al., 1998 ) being calculated from the Agri-Met Parma Weather Station data and Kc being the crop coefficient. Each year starting 2002, the crop

shown that there is a close correlation between evapotranspiration and pan evaporation. Therefore, the pan evaporation method is reported to be practicable for farmers in irrigation scheduling ( Kanber, 1984 ). The aim of this study was to determine the
