Synopsis

Synopsis

Coastal and Suwannee Bermudagrasses were more drouth tolerant, more efficient in water use, and more dependable from year to year as evidenced by much lower wet-year/dry-year yield ratios than common Bermudagrass, Pensacola Bahiagrass, and Pangolagrass. Fertilization increased the water-use efficiency of these five grasses. Three grasses required fewer roots to supply their nutrient needs than their water requirements. A greenhouse drouth-tolerance test applied to six grasses was well correlated with field results.
