The research of this thesis will focus on the performance of farm forestry trees in Mubende district, Uganda. In order to this, the research will help to fill the existing knowledge gap on the performance of farm forestry trees of east Africa specially Uganda. The conducted tree species are Markhamia lutea, Ficus natalensis, Mangifera indica, Artocarpus heterophyllus, Anitaris toxicaria, Persea americana, Albizia coriaria and Spathodea campanulata. The selection of the trees was mainly driven through the availability of age information. The trees were measured in height, age, DBH, length of commercial stem, diameter at specific height and visual observations e.g. occurrence and stem quality. To compare the performance of the conducted tree species a regression analysis with eight different functions was carried out for each tree species. The results are reproducible Stand- Height-Curves, height curves, DBH curves and curves for the single tree volume. The decision on the best curve was made on their biological plausibility and their statistical calculations. Additionally, the farmers of the trees were interviewed about their tree species for e.g. purposes of the tree, value of the wood and their own impressions on the growth of the tree species. The recommendation for the best applicable function is the Petterson function for the Stand-Height- Curve and the function of Richards for the height-, DBH- and single tree volume curve. Still these functions shouldn’t be used without comparison to other functions, especially because the used functions were developed for tree stand conditions and not specially for agroforestry conditions were the tree growth is in general higher. Additionally, an upscaling and prediction of the monetary tree values is made on the basis of the single tree volume curves and the interview results. The prediction of the farmers possible income through the cultivation of trees is made for Markhamia lutea, Ficus natalensis, Anitaris toxicaria and Albizia coriaria and assumes that 100 trees are planted on one hectare. Albizia coriaria 3.630 € achieves the highest possible extra income for the farmer followed by Ficus natalensis with 1.300 €, Anitaris toxicaria with 910€ and Markhamia lutea with 880 €. This thesis gives an example on the performance and possible monetary value of tree species in Mubende district, Uganda. Further investigation is needed to fill the knowledge gap in the performance of east African tree species and their values completely.
