The present research work aims to assess the impact of elevated temperature on rice production using three crop growth simulation models, namely, DSSAT, WOFOST and InfoCrop. Field experimental data-set of rice for seven years was used for model calibration and validation. After validation, three models were used to predict the yield under 1, 2 and3<sup>0</sup>C rise over normal maximum and minimum temperature. The models were also used to assess the thermal impact on leaf area indices (LAI) and crop duration. It was observed that the crop duration was shortened by almost 10 days for 3<sup>0</sup>C enhancement over normal and the LAI was also reduced considerably. The wet-season rice yield may be reduced by 8.7% for 1<sup>0</sup>C, 12.5% for2<sup>0</sup>C and 21.1% for 3<sup>0</sup>C increase of normal temperature. Use of combination of more than one crop models can predict the climate change impact on rice production more reliably.</p> ER -
