WA Northern Perennial Pasture Mix
Where practical remove weed burden before sowing. Sow in early spring when soil temperatures are 18° celsius and rising. Sow no deeper than 2cm.
As sub tropical pasture species are slower to establish it is recommended not to graze for up to 8 to 10 months after sowing
Once plants are well established refer to the grazing management information referenced later in this information sheet.
Do not overgraze over summer
Finecut rhodes grass has been bred from Katambora and offers improved dry matter production, increased leaf to stolon ratio over Katambora, has increased palatability and has excellent hay attributes.
Finecut is has finer leaves and stems than Katambora, has a more upright growth habit and over time has established itself across a wide range of soil types and farming systems throughout northern and southern Western Australia.
Finecut can be sown where grazing, silage and hay are required.
Reclaimer rhodes grass has been bred from the earlier collections of Finecut and Katammbora and selected for its agrresive establishment ability and increased number of growing points providing ground cover quicker than other varieties, making it ideal for erosion control.
Reclaimer has increased tolerance to saline conditions and could remain productive in saline soils up to 10 dS/m once established. Reclaimer has attributes similar to Finecut with finer stems, increased palatability and excellent hay attributes.
Reclaimer can be sown where grazing, silage and hay are required.
Gatton panic is a medium height bunch grass variety of guinea grass similar to Green panic. Gatton has broader dark green leaves and smooth stem nodes and will establish across a wide rainfall zone. Gatton will establish more easily than other panic grasses and can give very good first year production. Gatton can be grown on lighter soil types but requires good soil nutrition to persist.
Recommended for sowing North of Perth at a sowing rate from 4 to 6 kgs/ha.
For customers that require Signal grass, it is recommended that it be added at no more than 5% by weight
to this mix. Note: Signal grass contains "Steroidal saponins", which in certain circumstances can cause
photosensitisation where it is the predominant swarth component.
Once seeded shut the gate and do not graze until plants are well established. Plants must be well anchored and not able to be pulled easily from the soil. (Especially important with horses). This maybe up 8 to 10 months after sowing and most likely after the first autumn break.
After the first grazing has been completed move to a rotational grazing system where possible.
Perennial pastures need a longer spell between grazings than temperate pastures to grow the herbage (biomass) to achieve the best production outcome.
Like temperate grasses, perennial / sub-tropical grasses will increase the below ground root mass as the above ground leaf mass accumulates, increasing the accumulation of water soluble carbohydrates, (energy plants use) for later use to grow more biomass.
By adopting a rotational grazing system using the height suggestions below as a guide, the retention of biomass after grazing and the subsequent root mass retained will act as a reserve to kick start the next period of leaf growth.
Recovery from grazing will vary considerably depending on the time of year, biomass retained after grazing, soil moisture and plant nutrition. Once rotational grazing has been started a suggested guideline on grazing height for sub-tropical / perennial grasses is as follows: Going in at 25 to 30cm. Graze down to a residue of 12 to 15cm.
It is important to reduce grazing pressure over summer, (unless there is adequate moisture for plant growth), or when seed set is occurring. This enables the potential for some plant recruitment through seed set.
