In order to simulate wheat-faba bean intercrops better, APSIM should be improved regarding the calculation of biomass partitioning to grains in faba bean and of height growth in both species. APSIM was reasonably capable of simulating plant heights in pure cultures, but respectively overestimated and underestimated the height of faba bean and wheat in intercrops. The APSIM model has previously been used in the Loess Plateau (Tan, 2007 Chen et al. The model can simulate the biophysical process in farming systems, particularly economic and ecological features of the systems under climatic risk (Keating et al. In intercrops, APSIM systematically overestimated the aboveground dry matter and grain yield of faba bean and underestimated those of wheat. The APSIM model is an effective tool for making decisions on agricultural management. APSIM successfully reproduced aboveground dry matters and, for wheat only, grain yields in pure cultures.
#KEATING APSIM SIMULATOR#
We calibrated the Agricultural Production Systems sIMulator (APSIM) for pure cultures of wheat and faba bean using data from Dutch field trials, and determined the phenological parameters to simulate pure cultures and intercrops from seven field experiments across Europe. However, currently no existing crop growth model has been calibrated and tested for cereal-legume intercrops throughout Europea. Crop growth models can facilitate the understanding and prediction of the interactions between plant traits, crop configuration and management. Designing intercropping systems requires the integration of plant species trait selection with choice of crop configuration and management.

Recent international advisory roles have include Chair of the Science Advisory Panel of AgResearch - New Zealand (2013-2018) and Chair Independent Steering Committee of the CGIAR Program on Climate Change, Agriculture and Food Security (CCAFS) (2014-2019). Over the last two decades, Brian has held a number of senior leadership roles in CSIRO, including: Chief of CSIRO Sustainable Ecosystems (2004-2008), Director of Sustainable Agriculture Flagship (2008-2013) and the member of the CSIRO Executive responsible for Agriculture, Food and Health (2014-2015).īrian served (2010-2015) on the Australian Government's statutory committees responsible for independent advice on the scientific and environmental integrity of greenhouse gas mitigation programs- namely Carbon Farming Initiative (DOIC- Domestic Offsets Integrity Committee) and the Emissions Reduction Fund (ERAC – Emissions Reduction Assurance Committee). He was a pioneer in the application of simulation models in farming systems research in eastern and southern Africa in the 1980's and 90's. Brian's career has focused on the productivity and sustainability of agricultural systems in Australia and sub-Saharan Africa. This honorary appointment follows on from a 40 year engagement in agricultural research in Australia and abroad. Brian Keating (PhD University of Queensland 1981) is currently Adjunct Professor at the University of Queensland in association with the Queensland Alliance for Agriculture and Food Innovation (QAAFI).
