Dry sowing increases farm level wheat yields but not production risks in a Mediterranean environment
The assumed benefits and risks of dry sowing for different soils and locations in Western Australia were evaluated. This was possible using a multi-field (15 or 30 day sowing programmes), multi-year (54 seasons) simulation model analysis with the Agricultural Production Systems Simulator. The analysis evaluated dry sowing at the farm rather than the field level. Dry sowing has increased in WA, in response to reduced rainfall, increased variation in the timing and amount of autumn rainfall and increased farm areas.
