The objective of this paper is to develop a dynamic model that may be useful in the analysis of investment in long term tree crop agriculture. The model is based on linear programming as modified by fixed assets theory. The starting point is the Heady-Loftsgard dynamic linear programming model restated in a stochastic form and imbedded in a decision theoretic construct to give a stochastic mixed integer programming model. The paper goes into a discussion of problems associated with agricultural data collection in Nigeria-on the conviction that specific use of any model can only come after the data problem has been reasonably solved.
