Crop Modeling Activities at South Asia AgMIP Workshop ICRISAT, Andra Pradesh, India

Goals of the Crop Modelers during this Workshop: 1) to calibrate and intercompare multiple crop models (APSIM, DSSAT, INFOCROP, and STICS) against rice and wheat data at sites in South Asia, 2) to simulate growth and yield sensitivity of those four crop models for rice and wheat to temperature and carbon dioxide levels, and 3) to demonstrate the process of predicting district-level yield of peanut for three crop models (APSIM, DSSAT, and INFOCROP), following steps of calibrating, aggregating simulated outcome over multiple soils, sowing dates and weather sites, and finally predicting historical yields for Anantapur district after accounting for bias of observed district yields versus simulated. Data on growth, soils, management, and weather used during the Workshop were provided by the following colleagues:
