Solar radiation, temperature, and CO 2 are important climate variables on crop production. Climate change is a very serious threat to the agricultural sector and potentially bring new problems for the sustainability of agricultural production systems. This paper aims to know the impact of climate change on maize growth and production by simulating changes in climate variables. The case study was at Pak Chong District, Nakhon Ratchasima province, Thailand. There are eight treatments simulation and one treatment as a control; (1) no change (control), (2) solar radiation (SR) + 30%, (3) SR – 30%, (4) CO 2 + 25 ppm, (5) CO 2 – 25 ppm, (6) maximum temperature + 3 °C, (7) maximum temperature – 3 °C, (8) minimum temperature + 3 °C, (9) minimum temperature – 3°C. Simulation use Decision Support System for Agrotechnology Transfer (DSSAT) software. SR adds 30% obtained the highest yield due to the highest on grain number and pod weight. In contrast, SR - 30% reached the lowest.
