| Abstract/Contents: | "Small weighing lysimeters were used to determine potential evapotranspiration (ET) (i.e., ET when soil water is not limiting) rates of turf weeds and groundcovers. When ET was monitored during two consecutive summers, white clover (Trifolium repens L.) had the highest mean water use rate (7.4 mm day-1). Dichondra (Dichondra repens J.R. Forst. and G. Forst.), a low-growing C4 dicot, and barnyardgrass [Echinochloa crusgalli (L.) Beauv.], a C4 monocot, used the least water (3.9 and 4.1 mm day-1, respectively). 'Merion' Kentucky bluegrass (Poa pratensis L.), a C3 species, and yellow foxtail [Setaria glauca (L.) Beauv] and smooth crabgrass [Digitaria ischaemum (Schreb.) Muhl.], C4 species, exhibited intermediate ET rates. Water use rates of these groundcovers should be considered when using them in landscapes. Eradication of some weeds, such as white clover, in well-watered turf areas may be an effective means of reducing ET." |
