Trial information

Screening of frost in cereals - UA00162 - B Biddulph
Trial objectives
- To assess the genetic variation in commercial material for reproductive frost damage in commercial wheat and barley.
- Develop a rating system for frost susceptibility of commercial wheat and barley varierties suitable for use by industry.
- Screening international wheat lines with the Focused Identification of Germplasm Strategy (FIG)S for reproductive frost susceptibility
Frost tolerance in wheat - PhD project - B Leske
Crop type x time of sowing (TOS) trial - DAW00260 - B Biddulph, R Smith
Trial objectives
- Within a sowing window compare the relative frost susceptibility of wheat, barley and oats in frost prone landscapes.
- To develop across a sowing program the most stable and profitable cereal production in frost prone landscapes.
Hypothesis: Wheat is as profitable as barley and oats when phenology matches optimum time of sowing.
Nitrogen x seeding rate trial - DAW00260 - D Nicol
Hypothesis; Changing canopy density with seeding rate and nitrogen changes frost severity, duration, synchronisation of canopy development and frost damage.
Trial objectives
1. Use small plots to investigate the effect of nitrogen and seed rate on frost damage in wheat.
Intensive nitrogen x variety trial - DAW00260 - D Nicol
Hypothesis: Increasing nitrogen increases ground cover, dry matter, synchronisation of canopy tissue sensitivity to frost damage.
Trial objectives
- This trial will complement concurrent trials at other sites using larger plots investigating frost damage associated with different crop canopies and nitrogen concentration.
Debugging the role bacteria in frost management - K Ryan, B Biddulph
Hypothesis 1: Pseudomonas does increase frost damage (stem damage and floret sterility) in oats and wheat.
Hypothesis 2: A wet canopy does increase frost damage (stem damage and floret sterility) in wheat
Hypothesis 3: Ice nucleators do increase frost damage (stem damage and floret sterility) in wheat

Climate resources
Incidence of frost varies strongly across the agricultural region, with greatest occurrence in the central, eastern and southern parts. The severity map shown below shows how cold it got.
August
September
You can use this map to get a general indication of the likelihood of frost for your area for this season. Historical frost risk maps, show the past occurrence of frost risk.
- Frost risk maps shows the average number of low temperature events occuring in the months when crops are at most risk of frost damage from 1975-2014.
- Extreme weather events tool uses data from DPIRD's extensive weather station network to map extreme temperatures, either below or above a specified threshold. It provides real-time information about the location, duration and severity of frost and heat stress events, to help grain growers manage according to reduce their financial impact.
