A model incorporating four factors viz. the trend, season, rainfall and cycle was proposed to explain the variations of palm oil production in Peninsular Malaysia (CHOW, 1987). For the purpose of establishing the trend, an average yield profile (relating oil palm yield to palm age) for Peninsular Malaysia and East Malaysia by means of a mathematical function was used. The objective of this paper is to discuss a model for explaining yield variations in oil palm fields of estates by incorporating the yield profile equation referred to and variables of the other factors i.e. the season, rainfall and cycle as considered for the Peninsular palm oil production model. The model may be used to predict the yield of an oil palm estate. While the model may be satisfactory for explaining variabilities of oil palm yield in the past it is less so for prediction. However on the basis of the present model with its four main factors, modifications of the statistical techniques may eventually give improved results in prediction
