A 2-yr field study was conducted at the Turfgrass research facility, Auburn, AL to determine the relationship between irrigation amount, turf quality, and root length density for four hybrid bluegrasses (HB 129, HB 130, HB 328, HB 329) and two tall fescue (Green keeper and KY 31) varieties. These grasses were seeded fall 2004 and the experiment laid on a 6 by 6 Latin square design with 6 replicates of each treatment combination with a total of 108 plots, 1.0 by 1.5 m each established. Three irrigation treatments were applied to meet 100 %, 80 % and 60 % of potential evapotranspiration (PET). Tensiometers were installed at 7.5, 15 and 30 cm depths at the middle plots for each of the blocks and matric head values monitored daily from the tensiometers by use of Tensimeter pressure transducer. Turf color rating was determined from digital images taken once a week and analyzed for greenness using SigmaScan Pro 5.0 software, while root length density was determined from collected root samples using a Comair root length scanner. In the first experimental year, two of the hybrid bluegrasses (HB 129 and HB 130) performed better than the rest and were able to cope with extended drought stress than the rest of the varieties. Performance ranking, starting from the most drought tolerant was as follows; HB 130 > HB 129 > HB > HB 329 > KY 31 > Green Keeper. We concluded that water saving could be achieved by irrigating HB 129, HB 130 and HB 329 at 80% ET replacement without substantial loss in turf quality.
