Fig. 2. — The effects of irrigation treatments on average soil water content of split-rooted, 2-year-old ‘Gale Gala’ apple trees; C and PRD100 (A), and DI50 and PRD50 (B). Total daily water use of C, PRD100, PRD50, and DI50 calculated from the difference between morning and evening time-domain reflectometry measurements on successive days from DOY 200 to 211 (C). Data are means of five replications. Mean separation by Fisher’s Protected LSD test at P < 0.05. The inset in C provides the daily irrigation volume for individual treatments throughout the entire experimental period. Vertical dashed lines signify switches in irrigation between PRD ‘wet’ and ‘dry’ compartments (A, B). The bold arrow at the top indicates termination of the treatment period. On DOY 215, PRD50 and DI50 were changed to PRD100 and Control treatments, respectively.
