In this investigation, DSSAT 4.5 model was calibrated and evaluated to study the effect of elevated temperature and CO2 on growth and productivity of the maize crop. A 1°C increase in temperature from the present (mean of 1985-2008) may reduce the duration of the crop, which was sown in 3rd week of November, by 8 days under both 370 (current) and 550 (projected) ppm CO2 concentrations. A larger reduction (13 days) in crop duration was observed at 2°C increase in temperature, and the crop yield is likely to be reduced by 14% under 370 ppm CO2 concentration. The increase in temperature had adverse effect on leaf area index, total dry matter and yield. However, the effect of rise in temperature was less under 550 ppm CO2 concentration Not Available |
