| Abstract/Contents: | "Twelve perennial ryegrass (Lolium perenne L.) cultivars were evaluated for evapotranspiration (ET) rates in a field study, using mini-lysimeters placed in a turf area with 150 m fetch. Cultivars differed in ET, verdure, vertical elongation rate (VER), and root density. Evapotranspiration ranged from a low of 4.93 mm.day-1 for 'Prelude' on 3 Sept. 1987 to a high of 9.98 mm.day-1 for 'Linn' on 13 May 1988. 'Linn' had a mean VER that was twice that of 'Prelude'. VER was positively correlated (r=0.93) and verdure was negatively correlated (r=-0.89) with ET. Crop coefficients (Kc) ranged from 0.81 to 1.03. 'Linn' had a Kc > 1 on five of the six dates tested." |
