Potential for organic and inorganic fertilization for sustainable coffee production in Uganda

Abstract

The economy of Uganda is heavily dependent on Agriculture. Most of the export earnings come from coffee which is produced mainly by small scale farmers. However, the productivity of this crop has declined over the years. This has been atttibuted mainly to the decline in soil fertility. Therefore, experiments were set up in various parts of the country to study the effects of inorganrc and organrc fertiIizers on robusta coffee yields. Coffee husks were the organic fertilizer and NPK, the inorganic fertilizers. Results indicated that application of coffee husks and chemical fertilizers (NPK) in the different combinatrons increased the productivity of the crop.
