Synopsis High rates of N and P fertilizers and manure changed the botanical composition and increased hay yields from native flood meadows. Rush and sedge composed 62, 54, 12, and 4% of the hay at 0, 200, 400, and 600 lb. N/acre, while grasses composed 20, 44, 88, and 96% with the same rates of N. Yields of hay were significantly increased with N, P, and manure. The treatments had little effect on the crude‐protein content in the hay. Increasing rates of N decreased the P content in the forage.
