Frost

The impacts of frost and minimising variability in seasonal profits can be achieved using a combination of management solutions, tools and information. There are over 120 trials provided through OFT covering issues on frost including: frost tolerant varieties, managing frost risk, strategies to reduce frost damage, impacts of stubble management in frost prone areas and the grazing of crops to reduce the incidence of frost.

Refer to the Frost Identification Guide for Cereals to access additional information on identifying frost damage at various stages of plant development.

For further details on frost, refer to the document developed as part of GRDC’s National Frost Initiative, Frost – Frequently Asked Questions.

Aims:

Sowing date is a key driver of yield and variety performance. The optimum sowing time for an individual variety is a balance between having the variety flower too early and being subjected to frost damage, and conversely having it flower too late and experience prolonged heat stress. Both of these factors can have significant negative impacts on… read more
