Bambatsi panic

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 use Perennial summer-growing grass. Main production late spring, summer, autumn. Grazing.
Area of adaptation North West Slopes, North West Plains, Central West Plains, Central West Slopes, and irrigation.
Min. average annual rainfall 450 mm

Varieties Bambatsi
Sowing rates:
  • as only species - 2–4 kg/ha
  • in mixtures - 1–2 kg/ha
Sowing time Late spring to late summer, depending on district and summer rainfall, and on weed control.
