Background and objectives: Considering the increase in population and the establishment of food security and the cultivation of crops facing agricultural challenges with the problem of climate change; the present study was conducted to simulate the effects of climate change on the corn plant and to provide adaptation solutions for this plant to deal with the effects of climate change. Materials and methods: In the present study, used SSM-iCrop2 model in two periods (2025) 2010-2039 and (2055) 2069-2040 and under two release scenarios RCP4.5 and RCP8.5 in 23 meteorological stations of the country. Considering the increase in temperature and CO2 in the future, to improve the yield of corn, there are three strategies to adapt is considered, the change in the planting date, processing and combining the two strategies of late maturity and accelerating the planting, which increase the yield. Results: The results showed that the use of the late arrival strategy in both periods and the strategy of accelerating planting in the middle period (2055) and also the combination of these two strategies have increased the yield of the corn plant; this increase in 10% lateness with 20 days acceleration in planting was shown more strongly than other strategies. Conclusion: In general, it can be recommended that in order to deal with the effects of climate change in the corn plant, this plant should be of late type and should be planted 20 days earlier than the common planting date; so that the sensitive stages of growth such as flowering, pod filling and maturity are not faced with environmental stresses to have the best performance.
