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:
- Grain sorghum can be sown earlier than traditionally recommended in north west NSW
- Sowing sorghum earlier than the traditional 16 – 18 °C soil temperature recommendation is possible without negatively impacting on crop establishment and grain yield. As soil temperatures decrease, plant establishment percentages and the time to emergence increase
- Defining the minimum soil temperature required is still tenuous as temperatures are variable in the late winter/early spring and the risk of mild and severe frosts is still present
- ’Winter’ sown sorghum achieves earlier flowering and harvest times and subsequently increases the fallow length to the next crop, allowing increased opportunity for double cropping.
