Résumé
Ornamental landscapes and turfgrasses increase the beauty, aesthetics, utility, function and livability of any landscape. The green and turfgrass industries provide thousands of jobs and have a substantial economic impact. Estimates of New Mexico’s 2004-2005 economic impact of the turfgrass industry approached 1.4 billion dollars per year. However, these landscape areas and recreational facilities are experiencing increased pressure from government and society to conserve water and use the most efficient available method of irrigation. Between 30 and 70% of household water use may be applied to the outside landscape. Future demands for water may soon exceed the supply required. The goals of this experiment are 1) to determine the most promising modifications to current turfgrass management practices that could reduce turfgrass water use without impacting turfgrass quality, 2) to determine best turfgrass management practices for reducing potable water use on several turfgrass species maintained as a home lawn, and 3) to disseminate these results to turfgrass managers. Field experiments will be conducted to evaluate individual turfgrass management practices and the turfgrass response to those practices along a spectrum of applied irrigation. Results from these experiments will likely change how some turfgrass managers maintain their turfgrass swards and thus reduce the amount of irrigation required to maintain acceptable quality. These results may further reduce turfgrass water use by modifying marketing plans for large turfgrass product providers, thus directly impacting the end-user at the time of purchase.

Objectifs
To determine best turfgrass management practices for reducing potable water use on several turfgrass species maintained as a home lawn.Objective : evaluate recently available published research to determine the most promising turfgrass management practices to reduce water use.Objective : determine optimum nitrogen and phosphorus application rates for turfgrass establishment in relationship to turfgrass water useObjective : determine optimum nitrogen rate and source for turfgrass annual maintenance in relationship to turfgrass water useObjective : Continue to establish and analyze the relationship between herbicide efficacy and phytotoxicity to turfgrass water statusTo disseminate gained knowledge from this experiment to the NM turfgrass industries, NM homeowners and the greater scientific community.Objective : Provide real-time results through social media outletsObjective : Present results to the Rio Grande Golf Course Superintendents Association and other turfgrass industry groupsObjective : Mentor graduate and undergraduate student sObjective : Present and publish results to the scientific community
