Dr Rose Brodrick

Research Scientist, CSIRO Agriculture and Food

Dr Brodrick’s research is focussed on developing new technologies and integrated digital systems for the agricultural industry to improve farm productivity. She has 17 years’ experience in working with growers to develop agronomic management solutions in irrigated cotton production. Dr Brodrick’s current research area is using sensing technology to monitor the crop for irrigation decision making. Rose is a leader in the CSIRO’s  WaterWise Project that brings together a multi-disciplinary team that are developing digital solutions for precision irrigation as part of the CSIRO’s Digiscape Future Science Platform. Ultimately the aim is for these systems to part of a fully integrated irrigation toolbox for growers delivering savings in water that can be used to boost productivity or increase cropping area.

Abstract Outline: Australian cotton growers achieve some of the highest yields in the world and this is partly due to expertise in irrigation to match crop requirements. However, in situations where water is limited a key challenge for cotton growers is confidently knowing when to apply water to optimise yield, quality and water use efficiency. Ideally the timing of supplemental irrigations would minimise the potential downside risk and maximise yield potential of the crop with the water available. Historical weather data and the OZCOT cotton crop simulation model was used to identify the critical growth stages for maximising yield potential and characterise patterns of water availability in the best yielding crops in three row configurations and conversely identify the patterns in those crops that performed the worst. This study identified that whilst rainfall up to first flower contributed to yield, the most important characteristic of high yielding crops grown with limited water was the amount of rainfall that occurred during the period from first flower to first open boll.
