My research is focused on exploring the functioning of agricultural systems. My projects are often carried out in multidisciplinary teams and with the participation of multiple stakeholders e.g. farmers, private consultants, agribusinesses, policy. My aims are to understand how people make decisions and act, how those decisions can be informed, and how the final actions affect the performance of crops, animals, farm businesses, the broader environment and the social and food systems. I also provide science leadership to a multidisciplinary team of crop physiologists, agronomists, modellers and socio-economists i.e. QAAFI Farming Systems Research Group. The key mission of this group is to identify pathways for the sustainable intensification of agriculture in Australia and in low-income countries.
Evidence of his impact include, the development of whole farm simulation capacity within the APSIM model, which lead to UQ’s participation in a $40M project, resulting in the increased food security of 240,000 smallholder farmers in Africa; the production of evidence on how improved crop designs could deliver large profit gains (~$140 ha-1year-1) in Queensland’s 600,000 ha sorghum industry; and the identification of farm business designs that are more profitable, sustainable and resilient in face of increasing climate variability and change. He achieved this in partnerships with farmers, National and International donors and the private sector. His leadership in research is also evidenced by receiving 5 invitations as a keynote speaker at international conferences in the last 5 years. He annually present at industry forums, and he is active with government groups in the translation of his research into industry practice; and in informing policy. Prof Rodriguez leads and mentors a team of 5 full time researchers. He has successfully graduated 6 PhD students since starting at the University of Queensland in 2010, and mentored multiple Honours, MSc and MPhil students in collaboration with UQ Schools. He is presently the President of the Australian Society of Agronomy (2019-21) and organiser of the Australian Agronomy Conference, Toowoomba October 2021. Prof Rodriguez was member of the Local Confirmation and Promotions Committee at UQ’s Faculty of Science (2014-2016); he is member of the College of Experts at UQ’s Global Change Institute; he was Editor-in-Chief of Agricultural Systems 2013-2018 (IF 3.19); he is member of the Editorial Board of Agricultural Systems, and Associate Editor of Field Crops Research; he is one of the permanent organisers of the International Symposium for Farming Systems Design since 2009, the Global Food Security Conference in 2015 and 2017, and the World Congress on Conservation Agriculture in 2011; and organiser of the 2021 Australian Agronomy Conference in Toowoomba Queensland.

Pulses can increase profits, diversify income and increase sustainability. Megatrends in global food markets favour consumption of plant-based protein. However, significant productivity gaps remain, driven by lack of understanding of pulse physiology and agronomy. This project focuses on chickpea in Queensland, and will deliver location, soil and season-specific management options that optimise production to better enable growers to (i) attain water limited yield potential, (ii) increase profitability and (iii) reduce risk.
Background
Australia’s climate has warmed by about 1.4 °C since 1910, leading to an increase in the frequency of extreme heat events and the frequency and intensity of water stresses. Climate trends and ongoing climate change provide clear focus on the need to increase crop adaptation to water and heat stresses.
Here we propose that early sowing of sorghum could increase sowing opportunities and simultaneously avoid heat and water stress at flowering in some cropping systems and locations.
Previous research identified that early sown sorghum crops show high yield potentials with increased downside risk due to (i) poorly emerged crops when sown in cold soils, (ii) the likelihood of frost damage, and (iii) stunted growth due to lower than optimum air temperatures. However, there is no clear information on the benefits and trade-offs of the practice. Particularly there is limited information on low temperature thresholds for frost damage, cold temperature impacts on crop establishment, growth and development, water use dynamics, water use efficiency, yield potential and yield components, and the effects on subsequent crops in the cropping system for winter sown sorghum agronomic packages.

Pulses can increase profits, diversify income and increase sustainability. Megatrends in global food markets favour consumption of plant-based protein. However, significant productivity gaps remain, driven by lack of understanding of pulse physiology and agronomy. This project focuses on chickpea in Queensland, and will deliver location, soil and season-specific management options that optimise production to better enable growers to (i) attain water limited yield potential, (ii) increase profitability and (iii) reduce risk.
Background
Australia’s climate has warmed by about 1.4 °C since 1910, leading to an increase in the frequency of extreme heat events and the frequency and intensity of water stresses. Climate trends and ongoing climate change provide clear focus on the need to increase crop adaptation to water and heat stresses.
Here we propose that early sowing of sorghum could increase sowing opportunities and simultaneously avoid heat and water stress at flowering in some cropping systems and locations.
Previous research identified that early sown sorghum crops show high yield potentials with increased downside risk due to (i) poorly emerged crops when sown in cold soils, (ii) the likelihood of frost damage, and (iii) stunted growth due to lower than optimum air temperatures. However, there is no clear information on the benefits and trade-offs of the practice. Particularly there is limited information on low temperature thresholds for frost damage, cold temperature impacts on crop establishment, growth and development, water use dynamics, water use efficiency, yield potential and yield components, and the effects on subsequent crops in the cropping system for winter sown sorghum agronomic packages.
