This Thesis investigates the planning environment of rubber estates in West Malaysis, their input-output relationships, and through the application of planning techniques and criteria attempts to determine optimum replacement and crop diversification policies. The rubber planting industry, which comprises a multiplicity of estates and smallholdings that differ from one another in many aspects, has played an important role in the West Malaysian economy, She planning environment on estates was funnel to contain factors that greestly facilitate and simplify the task of estate management. The risk and uncertainty associated with product prices, yields, input coats and input-output relationships in long-term rubber production emphasise the need end importance of both long-term and short-term planning. Estimation of estate production functions, fertilizer response, commercial-experimental yield relationships and yield profiles for rubber undertaken to determine optimum input levels end provide other relationships and coefficients for use in short-term planning. Data deficiency and otter difficulties affected this quality of the results, and consequently limited their applicability to estate planning. Two common long-term planning situations the determination of an optimum replacement age for a given stand of rubber trees and planning for crop diversification on the basically monooultural estates, were analysed. In the former a deterministic replacement model we applied to different varieties of rubber trees depicting a representative crosssection of productive capacity on estates and smallholdings. With respect to crop diversifiostion the profitability of rubber, oil palm and cocoa on the major rubber growing soils in West Malasia was compared. Interoropping as a form of crop diversification on estates was assessed to be economically viable.
