Crop yields -- South Africa -- Mpumalanga Trees -- Yields -- South Africa -- Mpumalanga Timber -- South Africa -- Mpumalanga Pinus patula -- South Africa -- Mpumalanga Dissertations -- Forestry Thesis (MSc) -- University of Stellenbosch, 1998. This study establishes the minimum required yield for profitable production of sawtimber from Pinus patula in the escarpment area of Mpumalanga. Net Present Value and Internal Rate of Return are used as financial profitability criteria. All cost components are 1996 costs derived from the cost monitoring system of Forestry Economics Services (FES, 1997). The prices of pulpwood and sawlogs are 1996 prices used in the escarpment area of Mpumalanga.The prime overdraft rate from 1978 to 1997, used by Standard Bank, was used to estimate the Nominal Cost of Capital as 17%. By making use of regression analysis the long-term inflation rate was estimated as 13%. Based on these two estimated values for the Nominal Cost of Capital and the inflation rate, a Real Cost of Capital of 3,5% was calculated and used in the study.Two other scenarios were also used (a low Real Cost of Capital of 2,0% and a high Real Cost of Capital of 5,0%) to determine the minimum required yield. A scenario approach was followed in the discounted cash flow analysis, because this study is not intended to be applicable to a specific timber grower in the escarpment area of Mpumalanga.By means of the FINROT (FINancial ROTation) computer program 63 cash flows were analyzed. The result is that a minimum Mean Annual Increment at 20 years of age (MAI\({}_{20}\)) of 14, 17 and 20 m\({}^{3}\)/ha/annum is required for profitable production of sawtimber from Pinus patula in the escarpment area of Mpumalanga at a Real Cost of Capital equal to 2,0%; 3,5% and 5,0% respectively.The marginal MAI\({}_{20}\) as found in this study must not be thought of as something fixed or immutable. It can be reduced by the following: a) Annual increases in the nominal price of sawtimber which keep pace with inflation b) Exploitation of export markets in order to sell the products at higher prices; c) Soil analysis of growing sites and appropriate fertilizer applications; d) Effective matching of species to sites; and e) Effective and efficient execution of activities such as soil preparation, planting, weeding, pruning, thinning and clearfelling in order to get the optimum yield on invested funds.
