    fine fescue Scotland
  3. It depends on location • Cool-season grass: mean annual temperature

    < 14° • Warm-season grass: mean annual temperature > 20° • Transition zone: mean annual temperature from 14 to 20°. Warm- season or cool-season grasses can grow. Warm-season usually have lower inputs.
  4. None

  6. Later changed to warm-season grass paspalum/ryegrass Shanghai, 2014

  7. If cool-season grasses are used . • The species likely

    to give the best conditions with the lowest inputs in East Asia are creeping bentgrass (for tee, fairway, green) and tall fescue or fine fescue in higher cut areas.
  8. It also depends on water • What is the irrigation

    requirement? • [ET minus effective precipitation] adjusted for irrigated area, DU, and water source • What is the quantity of water available? • What is the quality of the water available?
  9. None

    experiment in December 2013. simulated fairway turf Thailand
  16. Zoysia matrella was 22% more efficient in water use and

    25% more efficient in N use. It does not require as much water or nitrogen to produce a dense sward. measuring water use Thailand
