Description Extreme temperatures around the flowering of wheat have the potential to reduce grain
yield and at farm scale their impact can be spatially variable. In this study, the zoning of
extreme temperatures, using data collected over two years, was carried out for a 164 ha
farm in the Southern Mallee, Victoria, Australia in order to identify areas at high risk of
extreme temperatures around the time of the flowering of wheat. Twenty-five data loggers
were installed at 0.8 m height across the farm to spatially record the daily course of
temperatures around the average date of flowering for the region. After applying the
zoning algorithms, the maps of different temperature zones were produced by spatial
interpolation in ArcView 3.2. It was found that in 2003, about 58% of the farm area was
prone to exposure to higher temperatures and about 73% to the lower temperatures
whereas in 2004 about 46% of the farm area was prone to exposure to higher temperatures
and about 39% to the lower temperatures.
