Best establishment and management of new varieties of phalaris locations
Aims

Demonstrate best practice phalaris establishment and management at the PPS/EverGraze site at Mooneys Gap which should provide information to producers to give them confidence to increase phalaris use.

Key messages
  • The Mooneys Gap phalaris site has shown that productive perennial grass and sub clover pastures can double the carrying capacity of a paddock when compared to a rundown annual pasture. The Mooneys Gap phalaris pasture has had an average increase in carrying capacity of 157% compared to the control annual pasture over the three years of the trial.
  • The introduction of deep rooted perennial pastures has environmental as well as production benefits. Perennial pastures are more efficient users of water as they are able to access available moisture at deeper levels and for longer periods than annuals and therefore assist in lowering water recharge reducing the risk of salinity. Perennials slow the soil acidification rate by the increasing nitrogen uptake thereby reducing nitrate leaching. Well managed phalaris pastures maintain a level of ground cover well in excess of annual grass based pastures reducing the risk of wind and surface water erosion. The Mooneys Gap phalaris site clearly demonstrates the enhanced environmental outcomes that come with well managed perennial pastures.
  • Soil testing is important to test for nutrient deficiencies and pH prior to phalaris establishment. Adequate lime and fertiliser should be applied to address deficiencies prior to establishment. Particular attention must be paid to ensuring that aluminium levels are suitable for phalaris production prior to sowing.
  • Weed control is of critical importance before and during the establishment phase of phalaris pastures. Periodic annual weed control measures enhance the production of phalaris based pastures after establishment.
  • A suitable fertiliser regime needs to be implemented to replace nutrients removed by the enhanced production of the phalaris based pasture.
  • Rotational grazing increases the persistence of the phalaris pasture.
  • The addition of phalaris pastures extends the period of available green feed when compared to an annual grass system.
  • The recent availability of the Holdfast GT Phalaris variety is an important addition to the perennial grasses that can be established in the region.
  • The claims that Holdfast GT will persist as well as Australian phalaris have not been tested due to the time required to obtain results from a new variety.
  • PPS will continue to test the persistence of Holdfast GT in the PDS trials as well as other pastures in the project.

The paddock was direct drilled with a Semeato disc seeder by Rinaldi Contracting Carisbrook Vic. The machine had only recently been imported from Brazil and did an excellent job sowing into the degraded pasture paddock.
