Synopsis Coastal bermuda, fertilized for 5 years with 3 rates and 2 frequencies of nitrogen from ammonium nitrate, ammonium sulfate, ammonium nitrate solution, anhydrous ammonia, urea‐ammonium nitrate solution, and urea gave relative hay yields of 100.0, 96.2, 98.3, 94.0, 92.3, and 81.3 and relative nitrogen recoveries of 100.0, 98.6, 95.2, 96.4, 86.1, and 74.0, respectively. In sand culture, Coastal bermuda utilized ammonia and nitrate nitrogen equally well. Spring lag in response to anhydrous ammonia was largely due to placement. Splitting nitrogen applications increased yields 0.6 to 1.2 tons per acre for all sources but anhydrous ammonia.
