Arabica coffee productivity can be increased through improved cultivation techniques. This research aims to analyze Arabica coffee production to treat shad ing, pruning, and coffee pulp-husk organic fertilizer application. The research was carried out in two stages, in the first stage a field survey was conducted to determine the relatively uniform land and plant characteristics, while in the second stage was the application of coffee pulp-husk organic fertilizer and pruning of shaded and non-shaded coffee plants by using farmer’s method and the recommended methods by the authors. The application of coffee pulp-husk or ganic fertilizer consists of 0, 2.50, 5.00, and 7.50 kg tree-1, which is equivalent to 0, 4, 8, and 12 tons ha-1 respectively. This research was arranged in a split-plot design, with shades placed in the main plot, while pruning and the application of coffee pulp-husk organic fertilizer in the subplots. The variables observed were the number of redcherries tree-1, greenbean (dry bean) production, and rendement (yield) production at 14% moisture content. Furthermore, the best effect and treatment were determined using variance analysis and the least significant difference (LSD). The result showed that shade only affected rende ment production at 14% moisture content, coffee with shade is better than no shade, pruning affected the number of redcherries and greenbean production. Furthermore, the recommended pruning was better than farmer pruning, while coffee pulp-husk organic fertilizer affected all observed variables. Therefore, the best dose is 7.50 kg tree-1 (12 ton ha-1) because the treatment combination (SxPxF) affected only greenbean production.
