The take home messages from this GRDC funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.
Take home messages from the paper include:
- Analysis of Australian national variety trials demonstrates impact of climate on wheat, barley, canola, chickpea and field pea grain yield.
- In all crops, higher temperature in the non-stressful range is associated with yield reduction when it occurs before flowering in the north, east and south and in all regions after flowering.
- In cereals, yield loss was greater when high temperature or water stress occurred during stem elongation.
- In canola and pulses, yield loss was greater when high temperature or water stress occurred from shortly before flowering and into pod filling.
- Canola was overall the most sensitive to water stress.
- The interaction between temperature and water stress had a regional pattern
