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