Forest bluegrass

NOTE: The information in this Agnote must be read in conjunction with Introduction to selecting and using pastures in NSW, which covers information on areas of adaptation, sources of variability, species mixtures, and important issues related to animal health and the conservation of native vegetation.
Pasture type and usePerennial grass producing main growth in spring, summer, autumn. Used primarily for grazing.
Area of adaptationNorth West Slopes and Plains
Min. average annual rainfall600 mm (summer rainfall dominant)
Advantages
  • Drought-hardy and tolerates grazing.
  • Productive, persistent.
  • Well adapted to ‘traprock’ or sedimentary soils in northern NSW.
Disadvantages
  • Will not tolerate waterlogging.
  • Frost-susceptible.
Soil requirementsVery well adapted to a range of soil types. Nutritional deficiencies of phosphorus and sulfur need to be addressed. A persistent legume can provide nitrogen.
VarietiesSwann **

Sowing rates
  • as only species - 2–4 kg/ha
  • in mixtures - 1–2 kg/ha
Sowing timeMid spring to late summer.
Companion speciesSubterranean clover, yellow serradella, barrel medic. These need to be maintained to improve grass production and quality.
InoculationN/A
Major nutrient deficienciesPhosphorus, nitrogen, sulfur.
Main insect pestsNo significant problems encountered.
Main diseasesNo significant problems encountered.
ManagementAvoid rank growth to maintain quality during season. Manage to maintain the companion legume.
Livestock disorders of particular   noteNo disorders encountered.
Additional tipsEnsure seed for sowing is free of declared noxious weeds.
Recruitment from fallen seed has been observed; stands may thicken over time.
