Improving wheat yields in dispersive soils
Examine how wheat yield can be improved by increasing tolerance to different soil constraints
Dispersive soils reduce wheat yields on 68 % of cropping land in Australia. These soils often comprise highly alkaline subsoils (pH > 9) and many other constraints including high salinity, high aluminium, waterlogging and high soil strength.
A current GRDC-funded project is aiming to improve the yield of wheat in dispersive soils by pyramiding tolerance to one or more of these soil constraints into elite wheat varieties. We have a range of projects involving the following research areas: plant phenotyping, plant nutrition, plant genetics, soil science and farming systems that can be tailored to your interests.
You will develop skills in:
- Plant phenotyping
- Soil chemical analysis
- Greenhouse, growth chamber and/or field trials
- Molecular biology, genotyping and/or gene expression, molecular markers
- Experimental design and data analysis
