ECONOMIC ASPECTS OF THE OPTIMUM REPLACEMENT OF SEEDLING TEA BY HIGHER YIELDING CLONAL VARIETIES

Agrekon, 1992, vol. 31, issue 2

Abstract: This article concentrates on the optimal replacement of seedling tea by higher yielding clonal varieties. A hypothetical 500ha tea estate under seedling tea is used for this purpose. Representative yields, revenues, costs and replacement data with respect to the hypothetical 500ha tea estate are discussed first. This is followed by a gross margin analysis. However, as this produces only partial answers which may be misleading, a whole farm approach to the replacement problem is subsequently taken. Dynamic linear programming is used to derive economically optimal replacement strategies over a 30 year planning horizon, given certain yield and price scenarios. Some conclusions are also drawn.
