Perennial Ryegrass
Tough on Seasons, Easy on Stock
Perennial ryegrass is the pasture base that keeps your system moving—reliable, resilient and easy to manage across seasons. It drives consistent feed from autumn break through spring flush, holds quality in the shoulders, and stands up to regular traffic in dairy and sheep & beef rotations. If you want a paddock that comes back time and again with usable feed, this is the grass you build around.
Modern mixes balance density and intake: diploids for tight, durable swards; tetraploids for animal preference and rapid recovery. Pair it with white/red clovers and select herbs to lift ME and seasonal flexibility, and choose proven endophyte options to help deter key insect pests and protect persistence. With the right fertility and drainage, perennial ryegrass underpins silage/hay as well as high-utilisation grazing.
Variants of Perennial Ryegrass
Stride (Tetraploid)
Late maturing; high sugar and high digestibility; very palatable; strong rust resistance; zero endophyte; typically 5+ years production.
Sowing: 30 kg/ha alone, or 20 kg/ha + 10 kg/ha Supremacy (diploid).
Supremacy (Diploid)
Reliable all‑rounder across NZ with good DM and rust resistance. Suitable alone or in mixes; pairs well with Stride/Algira, clovers and herbs.
For best results, sow in autumn at 25–30 kg/ha. Under the right conditions, the first grazing can typically occur within 8–10 weeks after sowing. Perennial ryegrass thrives in moderate-to-high rainfall regions and performs best alongside companion species such as white clover or plantain to enhance feed balance and soil health. Where early pest risk is expected, include a seed treatment to safeguard establishment and ensure strong early growth.
Long-term results speak for themselves.
Across dairy and livestock systems, perennial ryegrass has consistently delivered high dry matter yields, excellent feed quality, and reliable persistence over multiple years. Pasture tests have shown ME levels averaging 12.5–13.5 with high soluble sugars, supporting greater intake, animal performance, and milk production.
Algira (Tetraploid)
Very early maturing; high winter hardiness; high sugar and high digestibility; very palatable; strong rust resistance; zero endophyte.
Sowing: 30 kg/ha alone, or 20 kg/ha + 7–10 kg/ha diploid
Nui (Diploid)
Older cultivar with medium leaf and tiller density; known for solid persistence across a wide range of soils and climates.
