The Irrigation Mix is a blend of Amass and Achieve, combining Tetraploid and Diploid Italian Ryegrasses with Hypa, a new hybrid ryegrass being bred with 25% Italian and 75% Perennial ryegrass. Haifa White Clover serves as the legume component. Providing excellent production for dairy and livestock enterprises requiring extended seasonal production under irrigation.
Key attributes
- Highly productive under irrigation
- Blend of ryegrasses and white clover
- High quality feed for dairy and beef
- Strong seasonal production
- Suits grazing and fodder conservation

PGOne50 Perennial Ryegrass A new generation late heading Perennial Ryegrass bred from elite genetics from New Zealand and North-West Spain. |
Tribute White Clover Medium to large leaf type, summer active with high stolon density. PGOne50 Perennial Ryegrass is a late flowering type which delivers good feed quality through spring until early summer when it will then become reproductive, however this can be easily managed by grazing. PGOne50 Perennial Ryegrass is a late flowering type which delivers good feed quality through spring until early summer when it will then become reproductive, however this can be easily managed by grazing. PGOne50 Perennial Ryegrass has limited aftermath heading therefore the decline in feed quality is limited, retaining the attributes of high voluntary intake and cleaner grazing. PGOne50 Perennial Ryegrass has limited aftermath heading therefore the decline in feed quality is limited, retaining the attributes of high voluntary intake and cleaner grazing. To optimise production, introduce a rotational grazing system increasing or decreasing the rotation taking account of the seasonal conditions through the year. |
Amass Diploid Ryegrass: Ideal for areas where periodic winter waterlogging occurs. Persistent under heavy grazing pressure with quality feed in spring / early summer. Mid-Late heading date. Hypa tetraploid perennial ryegrass: Bred out of 25% Italian and 75% Perennial. A Mid-Later maturing variety selected for high dry matter yields over late winter to mid Spring with improved persistence in drier conditions. Tolerance to rust and suitable for sheep beef and dairy. |
Achieve Tetraploid Ryegrass: Good tillering and recovers well from grazing. Its upright growth habit prevents lodging during hay and silage production. Excellent rust resistance maintaining quality late in the season. Tolerance to waterlogging. Mid-late heading. |
Hypa tetraploid hybrid perennial ryegrass: Bred out of 75% Perennial and 25% Italian. A Mid-Late maturing variety selected for high dry matter yields over late winter to mid Spring with good persistence and tolerance to rust. |
Haifa White Clover: Small-medium sized leaves with high winter /early spring activity. Older variety with prolific seed set and some hard seed dispersed by livestock. Waterlogging and low PH tolerance. Irrigation Mix provides excellent production supported by good pasture management, appropriate nutrition, and irrigation to extend the production season. To optimise production, introduce a rotational grazing system, increasing or decreasing the rotation according to seasonal conditions. Recommended pH Rate: 5+ Recommended Rainfall Rate: 500mm+ Recommended Sow Rate: 25 to 30 kgs/ha. |
*Occasionally some varieties in our mix will be replaced with a like-for-like variety where the original is not available or not easily accessible. Varieties in the mix will be specified on the bag label.
About this variety
The Irrigation Mix is an Irwin Hunter formulation for country where water is not the limiting factor, and where the objective is to convert that water into as much high quality feed as possible.
It combines ryegrasses with white clover. Under irrigation a ryegrass will produce heavily provided nutrition keeps up, and the white clover component supplies nitrogen to the grass while adding protein and palatability to the sward, which is why the two are almost always sown together in an irrigated pasture.
Irrigated pasture is an expensive asset, and getting the blend right matters more there than almost anywhere else. Sixty years of supplying irrigators across the state sits behind how this mix is put together.
It can be established from March onwards under an early watering programme, which brings the pasture into production sooner than a rainfall-dependent sowing would allow.
The mix produces strongly across the season and suits both grazing and fodder conservation, particularly in dairy systems where consistent quality feed through the year is the requirement.
Planting & grazing notes
Rotational grazing, graze at 6-8cm to increase tiller density, manipulate late spring/summer to limit seed head development. Implement a rotational grazing program throughout the balance of the pastures life. PGOne50 Perennial Ryegrass is a late flowering type which delivers good feed quality through spring until early summer when it will then become reproductive, however this can be easily managed by grazing. PGOne50 Perennial Ryegrass has limited aftermath heading therefore the decline in feed quality is limited, retaining the attributes of high voluntary intake and cleaner grazing.
