Management Suggestions

Fertilization

Nitrogen should be applied in split applications during early Spring and Fall, and after first cutting. Adequate phosphorus and potassium are also necessary for top production.

Hay Cutting Schedule

First cutting in Spring should be done before head emergence (Boot Stage). Later cuttings can be made at 4 to 6 week intervals, depending on conditions.

Grazing

Rotational grazing is preferred for best production, persistence and quality. Fields should be grazed heavily and frequently (every 10 to 12 days) during the rapid Spring growth period, but overgrazing should be avoided. Leave a 3 to 4 inch stubble for quickest recovery. Extend mixes well with other species adapted to intensive grazing.
