1. Can flexibility be built into cropping systems for adapting to climate uncertainty? (practical, on ground, farming systems) Presenter: Darshan Sharma Centre for Cropping Systems Northam, WA This project DAW00202 'Demonstrating adaptation to climate change in the wheatbelt of Western Australia through innovative on-farm and virtual farm approaches' is funded by the Department of Agriculture and Food, Western Australia , the Grains Research and Development Corporation and the Australian Government's Climate Change Research Program . WA DAFWA Team: Caroline Peek, Glen Riethmuller, David Bowran, Doug Abrecht, Geraldine Pasqual, Meredith Fairbanks, David Gray,

3. Background

4. Background Challenge How to adapt farming system to ± ? We agree Climate is changing/changed In most of the Southwest of WA Temperature:  ± Rainfall : ↓ ± Source: IOCI

5. Hypothesis

7. Rationale

11. 3. Population control High plant density may reduce grain yield in rapidly warming and drying conditions.

13. We think, Shandying herbicide tolerant and intolerant varieties- a possible option to create an EXTRA decision point that MAY be used LATER in the season Photograph by: Harmohinder Dhammu Tolerant + Intolerant + Spray = Half the population
