Given low-fertility of Australian soils and high fertiliser prices, it is clear that sustainable, low-input grain production requires cultivars that are efficient in acquisition and utilisation of nutrients, particularly nitrogen and phosphorus as the most critical nutrients in most paddocks... Potential for increasing nutrient efficiency in Australian wheat and barley germplasm will be assessed in this project via large-scale field screening of promising genotypes for nitrogen-use efficiency at a number of locations spanning a range in climate and soil conditions..... Plant pre-breeders are laying the foundation for more nitrogen-efficient varieties of wheat and barley..
