New Tetila Tetraploid Annual Ryegrass

We recommend New Tetila Tetraploid Annual Ryegrass, a very reliable specialist winter crop. It establishes quickly and grows strongly through late autumn, winter and early spring, with production peaking in early to mid spring. It suits sandy through to heavy soils with a pH (CaCl2) of 5 or above in 500mm+ rainfall areas.

We recommend New Tetila Tetraploid Annual Ryegrass, which tolerates waterlogging and mild salinity, so it's a useful option for slightly salty, wet paddocks. It won't handle severe salt scald, where our Puccinellia or Tyrrell Tall Wheatgrass are better choices. On mildly saline ground, sow Tetila at 25-35 kg/ha together with suitable clovers.

Tetraploids like our New Tetila Tetraploid Annual Ryegrass have larger seeds and fewer tillers than diploids, so sowing rates are typically about double diploid rates. For Tetila we recommend 25-35 kg/ha plus clovers, increasing the rate where you apply more fertiliser for extra production. Tetraploids also have larger, darker leaves and higher sugar content.

New Tetila Tetraploid Annual Ryegrass is highly palatable, with large, wide, dark green leaves that encourage high animal intake. Tetraploids also carry higher sugar content, adding to their appeal. Because their cells hold more water, they give less dry matter per kilogram of feed than diploids, so we often suggest mixing in a diploid ryegrass for balance.

Yes, we often recommend it. New Tetila Tetraploid Annual Ryegrass brings palatability, large leaves and quick winter growth, while a diploid such as Dargo Diploid Italian Ryegrass adds tiller density and dry matter. Include suitable clovers as well, to lift feed quality and fix nitrogen. A blend gives a more balanced pasture than either type alone.

New Tetila Tetraploid Annual Ryegrass heads early, which suits shorter springs where you want to cut before the season finishes. It can be grown for pasture, silage or hay, with production peaking in early to mid spring, making it suitable for silage or early hay. Graze it through winter, then close the paddock up in time for the cut.

Our New Tetila Tetraploid Annual Ryegrass is produced under the Assure Quality Seedcare program, which protects varietal purity, so you get a genuine tetraploid. It traces to a vigorous tetraploid Italian ryegrass originally imported from the USA and naturally selected over several years in the ryegrass seed production areas of Victoria, so it's well adapted to Australian conditions.

We recommend New Tetila Tetraploid Annual Ryegrass for areas with 500mm+ rainfall, where good winter and early spring moisture lets it reach full production. It suits sandy through to heavy soils with a pH (CaCl2) of 5 or above. In lower-rainfall wheatbelt areas, a shorter-season diploid such as Wimmera Annual Ryegrass or Safeguard Diploid Annual Ryegrass (both 350mm+) may be more reliable.

Graze New Tetila Tetraploid Annual Ryegrass for the first time once plants are firmly anchored and won't pull out when tugged. Use rotational grazing and leave some leaf behind for quick regrowth. Early grazing encourages tillering, which is useful in tetraploids like Tetila that naturally produce fewer tillers than diploids. It establishes quickly with strong winter growth.

Choose on leaf type and season length, as both are early-heading annual ryegrasses. New Tetila Tetraploid Annual Ryegrass is a tetraploid with large, palatable leaves, suited to sandy through to heavy soils in 500mm+ rainfall. Dargo Diploid Italian Ryegrass is a diploid proven across a wide range of soils and shorter seasons from Esperance to Geraldton, from 400mm+, and is sown at lower rates. Mixing them gives a balanced pasture.
