Does stubble retention influence in-canopy temperature and frost risk? locations

The aim of this work was to better understand the impact of stubble management on in-canopy temperatures and the associated risk of frost in cropping environments with high yields and high stubble loads.

Key messages

• Stubble management can influence in-canopy temperatures.
• The in-canopy temperature of long stubble was colder than short stubble.
• All trial sites experienced fewer temperature extremes during 2016 than in previous years of this trial.
• There were no measured frosts during flowering in 2016. Further research is needed to determine the physiological significance of the observed temperature differences.
