Saia Oats

Avena Strigosa

Saia oats are a tall black seeded grazing oat with a fine stem. It is a fast-establishing autumn-spring growing fodder crop with high feed values and will provide good quality quick feed for hay and silage. It has a high leaf to stem ratio. It is a tufted annual that grows to nearly 2m tall.

Saia grows in a wide range of soil types and has a good tolerance of acid soils. Pastures rebound well after grazing.

It is a late maturing variety that is tolerant of acid soils
It is used in cover crop situations and as forage for sheep, beef Cattle, horses and Hay and Silage. It has readily acceptable palatability.

Regenerates from self-sown seed. Plants can regenerate for a season or two.

Susceptible to pugging; avoid grazing if waterlogged - regrowth will be compromised.

  • Recommended pH Rate: CaCl2 5.5+
  • Recommended Rainfall Rate: 350mm+
  • Recommended Sow Rate:
    Dry Land 60 to 100kg/ha
    In mixes:15 to 50kg/ha


Sow late summer/early Autumn for winter bulk. Soils should be well drained and it tolerates a broad pH range.

Sow between soil temperatures of 12°C to 25°C into a cultivated seedbed to a depth of 35-70 mm at 60 - 100 kg/ha depending on soil type/region and expected rainfall.

Sowing rates in mixtures: 15 - 50 kg/ha.

Can be sown dry (sow >50 mm). Fertiliser: Sow with 10 kg P/ha. If using MAP/DAP sow separately from the seed.
Graze prior to stem elongation. Strip graze along a long front to minimize trampling losses. Leave 12 cm residues/lowest stem node. Repeat grazing after a month's recovery.
Companion species: Legumes: clovers, peas, vetch, medics and Annual ryegrasses.

Major pests are Cereal cyst nematode, stem nematode, red legged earth mite, snails, cereal aphis (re BYDV transmission), cutworms, webworm, lucerne flea, army worm, Bruobia mite, wingless grasshoppers and Australian plague locust.

Major diseases are Leaf rust, stem rust, Septoria blotch, bacterial blight, barley yellow dwarf virus, halo blight, stripe blight, powdery mildew.

Herbicide susceptibility: Glyphosate.

Livestock disorders/toxicity: Young plants can accumulate a high level of nitrates and lead to nitrite poisoning, especially in cattle.

Slow growth, hot dry conditions or frost/hail damage can elevate nitrate level.

Saia’s winter feed value is typically 70% digestibility, 7-8% crude protein. It can produce up to 7 t DM/ha by spring where moisture is available and soil fertility is good.
