research Soil salinity and quality of sprinkler- and dripirrigated warm-season turfgrasses Most warm-season grasses can maintain acceptable quality when irrigated with saline water from a subsurface drip system. Increasing pressure to conserve potable water is driving increased irrigation effciency and the use of recycled or other impaired water sources for turfgrass areas. Currently, information is lacking on the longer-term sustainability of warm-season grasses irrigated with saline water from a subsurface drip system in transitional arid climates. A study was conducted at New Mexico State University to assess the effects of water quality and irrigation type on root-zone salinity and turf quality of several warm-season grasses in the arid Southwest. We also investigated whether or not summer salinity accumulation in the root zone Bernd Leinauer, Ph.D. Elena Sevostianova, Ph.D. 80 GCM June 2013 can be used to predict turfgrass quality for several turfgrass species and varieties. Materials and methods The study was carried out at the New Mexico State University golf course in Las Cruces, N.M. (USDA Plant Hardiness Zone 8), from 2005 to 2007. Turfgrasses Grasses were established in 2004 and included bermudagrass (NuMex Sahara, Princess 77, Riviera and Transcontinental); inland saltgrass (A138 and DT16); seashore paspalum (SeaDwarf and The study site was located on the golf course at New Mexico State University in Las Cruces, N.M.
