Dr Hizbullah Jamali

Research Scientist, CSIRO

Dr Hiz Jamali is a research scientist at CSIRO Agriculture and Food, Narrabri and completed his PhD from The University of Melbourne in 2012. Currently, Dr Jamali is working on irrigation agronomy of cotton and other irrigated crops. His major focus is on investigating utility of plant-based sensing techniques such as canopy temperature in irrigation decision making. Earlier, he has investigated the irrigation-nitrogen interaction and how this understanding can be used in reducing the nitrogen and water losses from irrigated systems, and mitigating emissions of greenhouse gas nitrous oxide. He has also worked as Post-Doctoral Fellow at Landcare Research in New Zealand researching nitrogen losses from irrigated pasture soils.

Abstract Outline: Cotton production in Australia is limited by water available for irrigation in most years. It is important to match irrigation applications with crop water requirements as both water stress and over watering results in yield penalties. This presentation will highlight the importance of using plant-based sensing techniques in irrigation scheduling decisions.

Canopy temperature is an important indicator of plant water stress. Through monitoring canopy temperature using infrared sensors we aim to understand crop’s demand for irrigation directly from plant as it integrates the effect of soil and aerial environment. The presentation will highlight our research over the last decade showing strong correlations between canopy temperature and cotton yield, and discuss mechanisms that drive these relationships.

Importantly, the presentation will discuss how our canopy temperature research resulted in development of a methodology for irrigation scheduling in fully irrigated cotton. The current research on utilizing this technique in partially irrigated systems will also be discussed.
