7 WATER USE EFFICIENCY GROUND COVER WATER USE EFFICIENCY INITIATIVE WUE INITIATIVE TABLE 1 Regional projects funded through the GRDC's national WUE initiative* REGIONAL PROJECT PRIMARY INTERVENTIONS IDENTIFIED FOR RESEARCH FOCUS 1. WA Sandplain (CSIRO Plant Industry) WUE under 'high' and 'low' fertiliser regimes over time Impact of early vigour x maturity x nitrogen on WUE 2. WA Central (CSIRO Sustainable Ecosystems) Identifying poor performing patches within farms, identifying nature of constraints, quantifying potential and trialling and costing amelioration 3. WA South West (CSIRO PI) Effect of management on water use and using soil water status to inform management decisions 4. WA South Coast (DAFWA) Identifying areas in which biggest WUE gains can be made 5. Eyre Peninsula Farming Systems Development, comparison and contrast of different WUE/yield potential tools through analysis of historic data Soil characterisation and measurement of spatial variability with EM38 and yield monitoring Wheat time of sowing x variety x soil type Phosphorus rate trial on good/medium soils and residual phosphorus trial 6. Lower Eyre Agricultural Development Association Improving barley and canola agronomy Better understanding plant/soil interactions to allow improved benchmarking of crop yields (5 soils characterised per year of project) 7. Upper North Farming Systems Summer fallow management Measuring and making the most of stored soil water Develop, compare and contrast different benchmarking tools (e.g. F&S, Yield Prophet®) based on historic data, use on focus paddocks 8. Hart Field Site Group Impact of stubble management on water supply and use efficiency Measuring and making the most of stored soil water Supply of seasonal yield potential forecasts to membership 9. Mallee Sustainable Farming Systems Improving management of continuous cereal systems (including managing soil and climate variability) Potential break-crops and impact on subsequent crops 10. MacKillop Farm Management Group Multifactor wheat and barley experiment at Frances and Conmurra (variety x BYDV x time of sowing) -- incomplete block design Ripping Water use of different crops Different soil types in the region, and how plant, soil and water interact -- determining yield potential 11. BCG (formerly Birchip Cropping Group) Making the most of out-of-season rainfall: impact of stubble and summer weeds on soil water, nutrients and subsequent crop yield The potential for low risk break crops to improve rotational WUE and profitability in low rainfall environments 12. Southern Farming Systems Wheat and barley x growth regulant x N timing x fungicide 'Achieving WUE' experiments targeting different yield potentials/methods of calculating different yield potentials Other experiments being developed in consultation with members 13. Irrigation Regions of SW NSW (NSW DPI) Optimising management for WUE -- soil type, crop choice, irrigation system and scheduling and water availability 14. Riverine Plains Drill opener x row spacing x rotation in no-till systems Canopy management in wheat: evaluating performance of N timing, plant population and row spacing interaction in a NTSR scenario Residue Management Trial -- assessing the influence of burning versus stubble retention in cereals. (Due to operational constraints, this experiment is unlikely to proceed in the 2009 growing season) The effect of summer cover crops on wheat yield -- effect of wheat yield on four different summer-growing cover crops sown following winter fallow 15. University of Tasmania Characterisation of soil PAWC for use in calculating yield potential Other experiments being developed 16. Central West Farming Systems Increase landholder ability to manage seasonal risk associated with water storage, WUE and nutrient availability Impact of stock on cropping system WUE 17. Farmlink Research Quantifying the impact of stock on WUE of controlled traffic, reduced tillage systems * Projects' nominated management interventions and management are colour-coded to the classifications made by the CSIRO WUE team for prioritisation of science and modelling effort.
