DROUGHT RESISTANCE OF WARM-SEASON PUTTING GREEN CULTIVARS ESTABLISHED FROM SOD ON NATIVE SAND
Putting greens are sometimes constructed on native soil and sodded to reduce costs and time of establishment.Water use requirements of warm-season cultivars has increased in importance due to recent drought and increased restrictions on fresh water irrigation.‘TifDwarf’ (TD) bermudagrass Cynodon dactylon (L.) Pers.x C.transvaalensis Burt Davy,‘SeaDwarf’ (SD) seashore paspalum (Paspalum vaginatum Swartz),and ‘PristineFlora’ (PF) zoysiagrass Zoysia japonica Stued.x Zoysia tenuifolia (L.) Merr. were sodded on Hallandale fine sand (Siliceous,hyperthermic Lithic Psammaquent) and irrigated at 25,50,or 100% of potential evapotranspiration (ETo) to compare their drought resistance.All cultivars wilted objectionably at 25,50,and 100% ETo.SD had the least wilting at 25% ETo.TD wilted most at 50% ETo.PF had the highest evapotranspiration (ET) rates,while SD had the lowest.Irrigation at 100% ETo was insufficient for all cultivars.
