Farming Systems to improve crop tolerance to frost - stubble management locations

To assess the impact of various stubble management practices on the extent, severity and duration of frost and determine its effect on canopy temperature and grain yield.

Key messages

Of the seven frost events that showed significant differences, all showed that the reduced stubble treatment (2t/ha) reached colder minimum temperatures than the removed stubble treatment (1.6t/ha). Across the seven events, the retained stubble treatment (2.5t/ha) also remained warmer than the reduced stubble treatment. The removed stubble treatment spent significantly less time at -2⁰C temperature threshold compared to the reduced stubble treatment. The retained stubble treatment was not significantly different to either of these.

These results suggest that removing stubble decreases the severity and duration of frost, however as discussed, there was variability in the results between the retained and reduced stubble treatments. This suggests, that in seasons where frost events are so severe, stubble management does not have a large effect on the severity of events.
