Description: Das Projekt "Management of Coffee Processing By-Products for Improved Coffee Production in Ethiopia" wird/wurde ausgeführt durch: Universität Hohenheim, Institut für Pflanzenproduktion und Agrarökologie in den Tropen und Subtropen, Fachgebiet Agrarökologie der Tropen und Substropen.The by-products of coffee processing are mainly coffee pulp and husk derived from wet and dry processing respectively. Due to the contribution of these by-products to environmental pollution, environmentally friendly disposal methods are necessary. The objectives of the study were to assess the manurial value of the by-products as potential organic fertilisers, quantify their subsequent effect up on the physical and chemical properties of coffee soils, and determine their effect on growth and yield of coffee. By-products of wet and dry coffee processing were decomposed and the chemical nutrients analyzed before and after decomposition. The compost from both by-products contained high level of major nutrients and physically suitable for coffee growth. The amendment of coffee processing by-products both decomposed and undecomposed caused a significant alteration in the physical and chemical status of coffee soils. The application of coffee pulp and husk compost significantly improved coffee growth and yield preceded by addition of N and P mineral fertiliser.
