Abstract

Crop production is amongst the many delicate occupations that would be affected by weather fluctuations. We assess the conceivable effects of climate change on maize production in Nigeria. DSSAT crop simulation model was employed for this study to predict the maize yield in the northern maize producing areas until 2039, using projected weather data and current management practices. Increased in temperature, carbon-dioxide and variation in rainfall pattern throughout the growing period were found to affect the maize yields. The results presented that maize yield, during 2016 – 2039, compared to the base-values are projected to decrease by 10.8%, 6.8% and 8.1% largely caused by temperature increase, CO2 and decrease in rainfall respectively. The results point out that maize yield could be more negatively affected by the temperature increase due to climate change.
