In addition, we identified threshold cold temperatures that significantly affected predicted yield, and combinations of locations, variety, and sowing time where the overlap between peak cold temperatures and peak flowering was minimal.

Simulated data, and data from field experiments grown in Australia (2013 to 2019), showed robust predictions for flowering time ( n = 29 R 2 = 0.97), and grain yield ( n = 22 R 2 = 0.63–0.70). We modified model parameters to include the effect of soil water on thermal time calculations, which significantly improved the prediction of flowering time. Regression analysis overcame this limitation of the model for chickpea crops grown at 95 locations in Australia using 70 years of historic data incorporating three cultivars and three sowing times (early, mid, and late).

The Agricultural Production Systems Simulator (APSIM-chickpea) model uses daily temperatures to model basic crop growth but does not include penalties for either frost damage or cold temperatures during flowering and podding stages. Crop growth models that predict flowering time and yield under diverse climates can identify combinations of cultivars and sowing time to reduce frost risk in target environments. The adverse effects of chilling temperature and frost in terms of the threshold temperatures, impact of cold duration, and genotype-by-environment-by-management interactions are not well quantified. The APSIM Oil Palm Workshop was supported by ICOPE-series (PT SMART, WWF, Cirad), ACIAR and CSIRO (Australia).įor more information, see: APSIM, ICOPE Series.During the reproductive stage, chilling temperatures and frost reduce the yield of chickpea and limit its adaptation.

It is hoped that the participants will be able to use and further develop the model to help improve sustainable production of this important crop.

On 2-4 December 2014, 24 scientists (12 from Indonesia, 4 from Australia, 3 from France, 2 from Colombia and 1 each from Liberia, Malaysia, Netherlands) participated in a workshop in Jakarta to learn how to run APSIM Oil Palm.

Evaluate GHG emissions from crop cultivation.

This is the first time a model of this type has been developed for the management of oil palm production systems.

Its development and maintenance is underpinned by rigorous science and software engineering standards APSIM is undergoing continual development, with new capability added to regular releases of official versions. It contains a suite of modules which enable the simulation of systems that cover a range of plant, animal, soil, climate and management interactions. The Agricultural Production Systems s IMulator ( APSIM) is internationally recognised as a highly advanced simulator of agricultural systems.
