Haymaster Orchardgrass is a new, late maturing (approximately 5 days later than Pennlate) orchardgrass with excellent yield potential. Haymaster can be used for hay, silage and pasture and is ideal for alfalfa or clover mixes. Haymaster Orchardgrass has excellent disease resistance, high yield potential, great forage quality, quick recovery after cutting and drought tolerance makes it the premier orchardgrass.

Management Suggestions

Fertilizer (pure stand): Fertilize according to soil test recommendations, but in general, nitrogen should be applied in split
applications during early spring and fall and after 1st cutting. Adequate phosphorus and potassium are also necessary for top production.

Cutting Schedule

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


Rotational grazing is preferred for best production, persistence and quality. Fields should be grazed heavily and frequently (every 10-12 days) during the rapid spring growth period but overgrazing should be avoided. Leave a 3-4 inch stubble for quick recovery.
