Resumé :  Description of subject. In the agricultural sector in Cameroon, the changes in climate variables are the great challenge facing each year by farmers and maize producers. The innovation of this study is the integration of soil moisture as a climate essential variable in the analysis of the change in climate (as recommended by WMO). More often, less study has been done to establish a link between the variation in Cameroon climate indices and the global climate indices. Rainfall, temperature, and soil moisture data have been downloaded as well as the maize Yield and global climate indices to determine the type of relationship among the climate variables and the yield.
Objective. This study was conducted to analyze the change in climate variables from 1950 to 2012 and to examine the effects of the changes in climate indices on Maize Yield in Cameroon.
Methods. Statistical methods were performed to question the change in climate variables (rainfall, temperature, soil moisture) from 1950 to 2012. The output data format use in this research are excel files and netcdf file. The excel format has been analyzed in the statistical tools such as R, SPSS and Excel 2016.
Results. Findings from this study revealed that temperature is increasing significantly (p-value 0.0017<0.05), while the precipitation is decreasing significantly (p-value 0.003<0.05) from 1950 to 2012. Although there is an increase in total soil moisture over Cameroon, there is a significant relationship between soil moisture and precipitation. These changes are significantly related to the Tropical South Atlantic Index located at the Atlantic Ocean which is next to Cameroon.
Conclusion. Additionally, Soil moisture is increasing with yield but there is not a significant relationship among both variables. So, the growth of yield cannot be explained based on soil moisture because they are other factors that can explain the increase in maize yield.
