Key attributes

  • Abundant tetraploid and Dargo diploid annual ryegrasses
  • Early to mid-late maturing blend for full season production

  • Highly productive over a wide range of soil types
  • Some assurance if the spring finishes early
  • Robust mix where clovers are prevalent from prior years

Mix components

Formulation 2026

Component
High quality, high yielding and long growing season. Excellent vigour with high stress and disease tolerance, and a constant proven performer.
The diploid addition provides greater adaptability with high winter and early spring production, and being a shorter season variety Dargo complements the Abundant for earlier productivity. A proven performer from Esperance to Geraldton in areas of 400mm+ growing season rainfall.

*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 seed blend

The Western Annual Ryegrass Mix is continually reviewed and updated with the most up to date proven varieties for Western Australian conditions. It currently contains a proven combination of Abundant tetraploid and Dargo diploid annual ryegrasses, two well-known performing varieties that are adaptable and highly productive over a wide range of soil types across WA, from Geraldton in the north to Esperance in the south.

This ryegrass mix provides some assurance all production will not be lost if there is an early finish to the spring. The earlier maturing variety will have supported the production, and where there is a longer growing season the later maturing variety will come into its own. In situations where clovers are prevalent from prior years, this is a good, robust mix.

When managed appropriately, Abundant has the potential to extend its vegetative production into late spring where sufficient moisture and crop nutrition is available.

Planting & grazing notes

Optimal sowing time is usually autumn: check for a combination of good soil moisture and suitable soil temperatures, with the possibility of follow up rain. When dry seeding for early production, make sure paddocks are clean of weeds and competitive grasses. Choose a sowing method that ensures good seed to soil contact, and control any persistent unpalatable weeds quickly. Increased sowing rates and fertiliser will encourage interplant competition during establishment, offering earlier grazing and higher dry matter production. Once established, ensure plants are not prone to pulling, then lightly graze at 8–10cm high to increase tiller density. Monitor for insect damage. Apply a rotational grazing program through winter and spring; fertiliser in spring will promote bulk growth.

FAQs

What's the best annual ryegrass to sow for winter and spring feed on the WA south coast?

We recommend our Western Annual Mix, which blends Abundant Tetraploid Annual Ryegrass with Dargo Diploid Italian Ryegrass and is adaptable and highly productive from Geraldton to Esperance. It suits sandy to heavy soils with pH 5.0 or higher in 450mm+ rainfall areas, and gives full-season production for grazing, silage or hay.

I'm worried about an early finish to spring. How do I avoid losing all my ryegrass production?

We recommend blending maturities, which is what our Western Annual Mix does. Dargo Diploid Italian Ryegrass is an early heading, shorter season ryegrass, so it supports production if spring cuts short, while Abundant Tetraploid Annual Ryegrass can extend vegetative growth into late spring when moisture and nutrition allow. Together they give some assurance that not all production is lost in an early finish.

How heavy should I sow annual ryegrass for good early grazing on a high rainfall paddock?

For our Western Annual Mix we recommend 15 to 30 kg/ha. Higher sowing rates, backed by extra fertiliser, increase competition between plants during establishment, giving earlier grazing and higher dry matter production. Once plants do not pull out, lightly graze at 8 to 10cm. The mix needs pH 5.0 or higher and 450mm+ rainfall.

When should I first graze newly sown annual ryegrass so it tillers up properly?

We recommend lightly grazing our Western Annual Mix at 8 to 10cm once plants are well established and don't pull out. This encourages tillering and thickens the sward. After that, rotational grazing through winter and spring keeps the pasture productive and leafy.

Is there a ryegrass mix that handles wet winters and a bit of salt on the flats?

Our Western Annual Mix is rated tolerant of waterlogging and mild salinity. It suits sandy to heavy soils with pH 5.0+ in 450mm+ rainfall areas. For badly salt-affected ground, we suggest talking to us about Puccinellia or Tyrrell Tall Wheatgrass instead, as annual ryegrass only copes with mild salt.

I want to cut silage and hay off a paddock that already has plenty of clover coming back. What ryegrass should I add?

Our Western Annual Mix is a good, robust choice where clovers are already present from previous years. It blends Abundant Tetraploid Annual Ryegrass, which has excellent silage and hay attributes, with Dargo Diploid Italian Ryegrass for production across the season. It flowers at roughly August to October, and suits 450mm+ rainfall on sandy to heavy soils.

Can I add clover to an annual ryegrass mix when I sow it?

Yes, clovers can be added to our Western Annual Mix where needed. Sub clovers such as Dalkeith Subterranean Clover or Riverina Subterranean Clover, or aerial clovers like Paradana Balansa Clover, add nitrogen and feed quality. If you want the legumes already blended in, our Silahay Pasture Mix combines Abundant Tetraploid Annual Ryegrass and Dargo Diploid Italian Ryegrass with balansa and Persian clovers.

What ryegrasses are in Western Annual Mix?

Western Annual Mix currently contains two annual ryegrasses: Abundant Tetraploid Annual Ryegrass and Dargo Diploid Italian Ryegrass. We review the mix regularly to use the most up to date proven varieties for WA. Abundant can extend vegetative growth into late spring, and Dargo is an early heading, shorter season type that gives high winter and early spring production.

Western Annual Mix vs Silahay Mix, which should I choose?

Choose based on your clover background. Both mixes use Abundant Tetraploid Annual Ryegrass and Dargo Diploid Italian Ryegrass and suit 450mm+ rainfall. Western Annual Mix is ryegrass only, suiting paddocks where clover is already present or you plan to add your own, while Silahay Pasture Mix adds Paradana Balansa Clover and Persian clover for extra legume quality in silage and hay.

Does Western Annual Mix come back the next year?

Western Annual Mix is an annual ryegrass blend, so it is mainly used for a single season of grazing, silage or hay. Some plants may reseed if paddocks are allowed to set seed, but we don't rely on it as a regenerating pasture. For self-regeneration, look at our Self Regeneration Mix or SouWest Pasture Mix.
