Tropical perennial grasses - root depths, growth and water use efficiency


Tropical perennial grasses offer high water use, high production and improved sustainability outcomes.

Water use efficiency (WUE) is a measure of plant growth per mm of water used – including rainfall and soil water.

For high water use efficiency adequate levels of nutrition and high green leaf area and root density are required.

Topics covered in this Primefact include:

  • Growth and dry matter production
  • Management tips to maximise WUE
