The Agricultural Production System Simulator (APSIM) Wheat model was used to test the sensitivity
of wheat cropping system for the Bhopal region in Madhya Pradesh to changes in temperature (0 to 5°C
from the base mean temperature) and atmospheric carbon dioxide concentration (0 to 550 ppm from the
base of 350 ppm). The wheat cultivar Sujata was used for this simulation study. It was found that there
was a negative relationship between grain yield and temperature while there were positive correlations
of grain yield with atmospheric CO2 concentration for the region under study. However, the rate of decrease
in grain yield was more for higher temperatures rise in contrast to lower temperatures, and the rate of
increase in grain and biomass yield was more for higher CO2 concentration compared with the lower
levels. On an average, there was 8% decrease in wheat grain and biomass yield per 1 °C increase in
temperature. On the contrary, wheat grain yield increased by 33% and biomass yield by 35% with the
elevation in CO2 concentration from 350 to 850 ppm. Increasing the temperature by1 oC and CO2
concentration to 500 ppm, the yield decline in wheat was lower than individual effect of increased
temperature. This study showed that environmental factors have significant effects on wheat grain and
biomass yield with changes in atmospheric CO2 and temperature. These findings provided a sound
basis for preliminary coping and prioritizing adaptation options for the future climate change scenarios
