Machine Harvest Trial Methodology

Challenges

  • Variability in paddock soil type/water application across trial
  • Weed pressure
  • Adverse weather events
  • Sourcing new cultivars – increasing seed testing costs

Current Machine Harvest Trials

  • Randomised complete block design
  • Five replicates where possible
