Popis: Monthly evapotranspiration (ETa) of Argentine mesquite (Prosopis alba Grisebach), desert willow (Chilopsis linearis (Cav.) Sweet var. linearis) and southern live oak (Quercus virginiana Mill., nursery seedling selection) were compared with tall fescue (Festuca arundinacea Schreb.) and common bermudagrass (Cynodon dactylon (L.) Pers.) overseeded with perennial ryegrass (Lolium perene L.) over a two-year period at a field site in Las Vegas, NV. Immature trees (56.8 L container nursery stock) and tall fescue were grown in 190 L plastic lysimeters in which weekly hydrologic balances were maintained. Evapotranspiration of bermudagrass/ryegrass was estimated from crop coefficients (Kc) and potential evapotranspiration (ETo) predictions. ETa of the trees and tall fescue (L/lysimeter) was shown to increase as the leaching fraction (LF = drainage/irrigation) increased. The ETa data were compared on an area basis by dividing tree ETa by measured basal canopy areas and turfgrass ETa by the land area on which the gra...
