The production of coke through monocropping is a major concern for Gabonese farmers. A test was conducted with a random Fisher block design with four replications. The treatments consisted of coffee hust, NPK 15-15-15 and a combination of coffee husk and NPK applied to monocrop and crop association. Dosages made by micro-plot were: 240 g, 320 g and 400 g for the husk; 5.6 g of NPK; treatment combinations were to combine the NPK at different levels of parchment. The results show that fertilization increased coffee growth and induces production of higher peanut in the case of the witness. The difference compared to the control for parameters: stem diameter, stem height, leaf area, leaves and buds number measured on coffee plants and yield of groundnuts are respectively: 0.158 cm, 1.91 cm; 30.8 cm2; 12.53; 1.57 and 190 kg/ha. The yield of groundnut monoculture is higher by about 69% compared to the intercropping system that affects 45% average growth of the coffee plant. Most important in this model is the yield, it appears that the combination of coffee-peanut crop was not beneficial to the soil tested. The coffee husk compost, applied alone or in combination especially parchment-NPK, could be considered as fertilizer to improve the growth of the coffee and peanut production, monoculture under the conditions of the southeastern Gabon.
