This study analyzed how extreme weather conditions affect the mean and variability of the yields of 11 staple crops in Nigeria. The research involved the use of a pooled panel data of 36 states and the federal capital territory over the period of 1991-2012. The framework for analysis consisted of the production risk model developed by Just and Pope for yield estimation. Unit root tests and Maximum Likelihood Estimation techniques were used to obtain reliable estimates of the model’s parameters. The results showed that the mean and variance of the yield of all the staple crops were diversely influenced by extreme weather events.
