perennial ryegrass

Russian Research Institute of the Russian Academy of Agricultural Sciences

Maximum yield in production:

74.3 t/ha of dry matter

State Register

Northern, North-Western, Central, Volga-Vyatka, West-Siberian, Far Eastern regions

Development features

High winter hardiness, the drought tolerance is above average. Dry matter yield on non-irrigated plots is on average 11 t/ha. The seed yield amounts to 600–800 kg/ha (up to 1,200 kg/ha in individual years). Crude protein content in hay of the 1st cut amounted to 16.7%, water soluble carbohydrate content 15.7%. It is intended for 3 cuts or 4-time grazing in Non-Black Soil area conditions.

Planting time

Sowing during the entire season is possible, until September (for lawn purposes), subject to sufficient moisture level

Seeding rate (viable seed/m²)

10–12 kg/ha — for seeds, regular row sowing
6–8 kg/ha — wide row with an inter-row distance of 30 cm
25–30 kg/ha — for forage, row sowing
30–50 g/m² — lawns

Soil requirements

In the autumn of the year preceding sowing, compound fertiliser based on P90K150. Prior to sowing and in the spring in subsequent years prior to regrowth, 45‑60 kg/ ha N.

Disease resistance

Highly resistant to rust, powdery mildew, snow mold

Intended use

Forage cutting, pasture, lawns
