Capturing this advance with reduced complexity compared to the N concentration approach provides a firm basis to progress the role of modelling in exploring the genetic underpinning of complex traits and in plant breeding and crop improvement generally. This supports the use of the model to extrapolate and predict performance and adaptation under new GвЂЇГ—вЂЇMвЂЇГ—вЂЇE combinations. Comprehensive model testing indicated accurate predictions at organ and crop scale across a diverse range of experiments and demonstrated that observed responses to a range of management factors were reproduced credibly. The current version of the model is implemented within the APSIM Plant model framework which is currently used for other crops such as grain legumes and canola. There was considerable correspondence with parameterisation results found for sorghum, suggesting potential for generality of this framework for modelling crop N dynamics in cereals. 1 The APSIM Wheat Model Brown, H.E., Huth, N.I. APSIM-Barley was developed from a combination of the approaches used in previous APSIM barley modules: Asseng et al. The N modelling framework is described and its parameterisation for maize is developed based on three previously reported detailed field experiments, conducted at Gatton (27вѓ4вЂІS, 152в‚0вЂІ), Queensland, Australia, supplemented by literature data. The objective was to implement the conceptual framework of the APSIM sorghum nitrogen dynamics model in APSIM maize and to validate the robustness of the model across a range of GвЂЇГ—вЂЇMвЂЇГ—вЂЇE combinations. 1 The APSIM Soil Nutrient Model The APSIM Soil Nutrient model has been developed using approaches similar to those employed in the APSIM Plant Modelling Framework (PMF) of Brown et al., 2014.

Here we present a physiologically more robust approach, originally implemented in sorghum, which uses the N content per unit leaf area as a key driver of N demand. Most efforts on modeling the nitrogen (N) dynamics of crops use a minimum, critical, and maximum N concentration per unit biomass based empirically on experimental observations. Crop growth simulation models require robust ecophysiological functionality to support credible simulation of diverse genotypeвЂЇГ—вЂЇmanagementвЂЇГ—вЂЇenvironment (GвЂЇГ—вЂЇMвЂЇГ—вЂЇE) combinations. model can accurately simulates field data, to use it to investigate the yield of canola in California under different irrigation man-agement strategies across the cereal cropping regions of the state, using current and anticipated future climate scenarios.
