Stubble rate response for the management of frost severity - Tincurrin locations

Determine if there is an interaction between temperature and various rates of stubble and outline whether increased stubble loads change the severtiy and duration of frost.

Key messages

Temperature results from both sites have demonstrated that stubble loads above 2t/ha increased the severity and duration of some frost events. Analysis of results on yield and frost damage is ongoing and will be presented.
