Fig. 3. Dry matter (DM) yield by harvest of bahiagrass fertilized at 80 (BG-80) or 320 kg N ha^–1 yr^–1 (BG-320) under ambient (360 µmol mol^–1) and enriched (700 µmol mol^–1) CO₂ levels for 1998 and 1999. There were no CO₂ effects at any harvest for BG-80 in 1998 (P > 0.16) or 1999 (P > 0.50). For BG-320, P values for Harvests 1 through 4 were 0.26, 0.02, 0.09 and 0.05, respectively, in 1998, and 0.09, <0.01, 0.42, and 0.18, respectively, in 1999.
