Native grass production and water-use efficiency were increased by nitrogen ferilization and by greater available moisture supply. Water-use efficiencies were greatest for the 0-N and 80-N treatments when available water supply was 15 and over 20 inches, respectively. Fertilization increased water use only where subsoil moisture reserves were high.
