Zerihun Gudeta Alemu,  Klopper Oosthuizen and  Herman van Schalkwyk 

Abstract: This study has two objectives. First, to extract a cycle from agricultural GDP. Second, to compute the periodicity of the cycle. To achieve these objectives, a univariate time series procedure is applied. It is found that agricultural GDP is cyclic and that the cycle occurs every 8.25 years.
