Managing frost risk through better wheat agronomy locations
Aims

To investigate adaptation of new wheat varieties in their resilience to frost stress during the growing season.

Key messages

The occurrence of frost and subsequent frost damage to grain crops is a complex phenomenon. The factors affecting frost damage in wheat crop include seasonal conditions (temperature, humidity, and wind), soils characteristics (topography, soil type), variety (maturity and flowering window) and agronomic management (sowing date, row spacing, and seed and fertiliser inputs). In 2012, frost had significantly damaged and reduced the grain yield for all varieties at two different sowing dates at Wickepin. On average the later sowings (8 June) yielded 1 t/ha greater than the earlier sowings (18 May). Comparatively longer season varieties such as Magenta and Calingiri flowered late, avoided some of frost damage and yielded the highest at both sowings. Preliminary results indicate varieties differed in their relative performance and resilience (i.e. ability to yield) in response to stresses of radiant frosts in both time of sowings. More comprehensive results on variety performance and frost damage will be available after measuring grain quality and sterility estimates.
