Productive, Persistent Tropical Grasses Project (P1 FP07)

The Productive, Persistent Tropical Grasses project will develop and commercially release new tropical grass varieties for the south coast and the northern agricultural areas of WA and northern NSW.

This includes the selection and release of a new Panicum maximum variety following evaluation under grazing in two key target environments. The variety release will be accompanied by regionally targeted information on issues such as establishment and grazing management. Agronomic packages for tropical grasses including suitable legume options, establishment techniques, and management requirements will be developed and promoted in WA and northern NSW.

Objective:

  • Select and release, in conjunction with a commercial partner, a new Panicum maximum variety (under Trademark) following evaluation under grazing in two key target environments
  • Determine suitable legume options for use in perennial grass-based farming systems in WA and northern NSW, along with establishment techniques, the management requirements for persistence/regeneration and in northern NSW the hydrologic response
  • Develop, demonstrate and promote agronomic packages for high production – high quality perennial grass-based farming systems for both WA and northern NSW. These regionally targeted packages will cover a range of key issues relevant to each area such as establishment, legume options and management, N fertiliser use, grazing management, utilisation strategies and the role of supplements.

Activities

Project team members have successfully established grazing trials at three sites to evaluate the persistence and productivity of the new grass lines. These sites are located in northern NSW are at the Tamworth Agricultural Institute and at ‘Mitiamo’ located about 25 km west of Bingara.

In WA, the Panicum grazing trial has been successfully established within a 10 ha paddock on Badgingarra Research Station with grazing and pasture measurements underway.

A range of the field experiments have been successfully established in both northern NSW and WA in 2009 to address the issue of a companion legume to improve the feed nutritive characteristics and to provide the soil nitrogen to drive the productivity.

Tropical perennial grasses guides

Research from this project has been used to produce a series of guides that promotes the use and management of tropical-grass based pasture mixes in the summer-rain dominant region of New South Wales.
