| Abstract/Contents: | "Selection of the appropriate genera and cultivars for use in areas where water is limited should be based primarily on turfgrass water requirements. The linear gradient irrigation system (LGIS) at TAES-Dallas was designed to determine water requirements of turfgrasses under field conditions. A long-term goal of this project is the development of new cultivars that require less supplemental irrigation to maintain quality turf. The objective of this study was to determine the amount of supplemental irrigation required to prevent water stress and maintain acceptable turf ground cover for commercial and experimental zoysiagrasses. The experiment was conducted at the Texas A&M Agricultural Experiment Station at the Research Center, Dallas, TX on a Houston clay (fine, montmorillonitic thermic Udic Pellustert). A randomized complete block with 84 plots each 1.5 by 19.5 m was used. A total of 21 different zoysiagrasses were planted during 1987. During July 1989 through August 1991, irrigation water was applied every third night at a rate 1.2 times the previous 3-d ET rate based on a Class A Weather Pan. Water distribution for the gradient was determined by measuring irrigation water collected in rain gauges positioned at 1.5 m increments from the line irrigation source. Concurrently, turf wilt and green color loss, indicators of drought stress, were visually determined at 1.5 m increments from the line source. Mean annual supplemental irrigation requirement ranged from 93 to 677 mm. Of the commercial cultivars, FC13521 and Emerald required the most, El Toro the least, and Meyer and Korean common were intermediate in supplemental irrigation water required to prevent stress. El Toro, Emerald, FC13521, and several experimental zoysiagrasses maintained acceptable ground cover with no supplemental irrigation. This study indicates substantial genetic variation in water requirement among zoysiagrass germplasm." |
