GRDC Research, Development and Extension Plan 2018-23

GRDC Key Investment Target 1.1


Growers manage their farm businesses to minimise the impact of flowering heat stress on yield.

  • Growers understand how much the impact of heat stress on yield is costing their businesses.
  • Growers understand their options to manage heat stress.
  • Varieties with increased tolerance to heat stress.
Improved pre-season planning for heat stress

Growers make optimal crop choice and sowing decisions in heat affected cropping regions.

  • 1.1.1
    Growers have access to varieties with improved yield under heat stress.
  • 1.1.2

    Growers use accurate information on the pattern and severity of heat stress in their region to guide variety selection and sowing decisions.

  • 1.1.3
    The grains industry has access to accurate information about the relationships between the severity and timing of heat stress and the impact on yields of major grain crops.
  • 1.1.4

    Plant breeders have tools to effectively improve the heat tolerance of major grain crops.

Informed in-season management decisions

Growers optimize canopy management and type and timing of crop inputs to minimize the impact of heat stress.

  • 1.1.5
    The grains industry has improved in-season forecasting tools to better predict heat stress and guide risk management decisions.
  • 1.1.6
    Growers have improved knowledge of how different crop input and canopy management practices influence yield under heat stress.
  • 1.1.7
    Growers have access to novel and innovative in-season heat mitigation products.
Effective post-heat event responses

Growers make informed decisions regarding extracting value from heat affected crops.

  • 1.1.8
    Growers have access to tools to predict, monitor and quantify yield loss associated with heat stress.
  • 1.1.9
    Growers have knowledge of the economic value of different salvage options which can be applied to heat-affected crops.
