Irrigation Requirements of Tall Fescue and Kentucky Bluegrass Cultivars Selected Under Acute Drought Stress
M. D. Richardson, D. E. Karcher, K. Hignight, and D. Hignight
There are a number of ways to reduce water use in urban landscapes, but planting turfgrass cultivars that can perform and persist under restricted water is an important component of these systems. A turfgrass screening protocol has recently been developed that allows selection of cultivars that can retain green cover under acute (no water) drought stress conditions. The objective of the present study was to determine if cultivars of tall fescue and bluegrass that were selected under acute drought screening could also conserve water under restricted irrigation habits or chronic drought stress.
