Abstract
The objectives of this project towards increased profitability and water use efficiency was to:
1. Build on past research to develop guidelines to support tactical and strategic decisions regarding a) timing of limited water applications, b) water allocations to each paddock, c) extending ratoon life, d) making use of water upflow from water tables and e) withholding irrigation to reduce risks of waterlogging;
2. Further enhance sugarcane systems modelling capability;
3. Customize tools for industry; and
4. Work with extension officers in applying these tools in an action research context with industry.
