Fig. 2. Changes in turfgrass quality (TQ) for creeping (CRP), colonial (CO), and velvet (V) bentgrasses under deficit irrigation in 2002 and 2003, where 9 represents the best quality (green, dense canopy) and 1 represents the lowest quality (brown, desiccated). In 2002, irrigation treatments were applied from 1 July through 18 August and then again from 13 September through 1 November. In 2003, treatments were applied from 27 June through 8 September and then again from 1 October to 1 November. Symbols indicate the irrigation treatment as a percentage of ET measurements with weighing minilysimeters. Vertical bars are LSD values (P= 0.05) within a species indicating statistically significant differences for treatment comparisons at a given day of treatment.
