Synopsis Maximum yields of 3.4 and 7.9 tons per acre of Ky. 31 fescue and Coastal bermuda, respectively, were obtained on Ruston loamy fine sand fertilized with up to 800 pounds of N per acre. Near maximum yields were obtained from 200 and 400 pounds of N per acre on fescue and Coastal bermuda, respectively. Coastal bermuda produced twice as much crude protein as fescue. Severe thinning of fescue stands occurred at the 400‐ and 800‐pound rates of N. Water soluble carbohydrate was considerably lower in fescue at these high rates of N.
