Trial location(s) Maya, WA
Effect of stubble height on crop growth locations
Aims

To check whether higher stubble affected crop growth.

Key messages
  • Stubble height would appear to have a statistically significant effect on early lupin plant height.
  • This effect, although trending towards a higher lower pod height on those plants, is not statistically significant in this trial.
  • This trial had insufficient measurements taken to determine the mechanism that caused the plants growing in the tall residue to grow taller and have a higher first pod, and whether that led to an increase in yield.
