‘Coastal’ bermudagras( Cynodon dactylon (L.) Pers.) with and without supplemental irrigation on Cecil sandy loam fertilized with seven N:K treatments (224:224, 224:112; 224:37, 672:672, 672:336, 672:112, 1120:560 kg/ha per year) was clipped at 2‐, 4‐, and 6‐week frequencies. Analyses of the forage for TAC (Total Available Carbohydrates) as measured by the soluble plus hydrolyzable (2% v/v H 2 SO 4 ) carbohydrates, showed that irrigation and fertilization decreased the percentage TAC but increased the total TAC production per hectare due to higher yields. Extending the clipping interval increased both the percentage and yield per hectare of TAC.
