Entretanto, devido ao aumento nos custos dos fertilizantes minerais, o fornecimento das quantidades recomendadas de nutrientes vem se tornando limitante para os produtores rurais. O objetivo deste trabalho foi avaliar a utilização de compostos orgânicos no plantio do cafeeiro conilon, com o intuito de substituir as adubações de cobertura com N e K recomendadas na fase de pós-plantio. O experimento foi realizado em casa-de-vegetação, em Linhares-ES, sob delineamento experimental inteiramente casualizado, em esquema fatorial (2x5), com cinco repetições. Foram avaliadas cinco doses de dois compostos orgânicos misturados ao solo. Cada parcela experimental foi constituída por um vaso de 12,8 L, que recebeu uma planta. Os compostos constituíram-se da mistura de esterco bovino curtido e capim-elefante (C1), e de cama-de-frango e capim-elefante (C2); ambos na proporção 1:4. As doses utilizadas foram 0; 0,853; 1,706; 2,559 e 3,412 kg/vaso do C1; e 0; 0,758; 1,516; 2,274 e 3,032 kg/vaso do C2. Tanto o tipo do composto orgânico como as doses aplicadas interferiram no crescimento e nos teores foliares de macronutrientes. As doses que proporcionaram os maiores acúmulos de matéria seca total foram de 1,623 kg/vaso (≈ 8,115 kg/cova de 64 L) do C1 e 1,733 kg/vaso (≈ 8,665 kg/cova de 64 L) do C2. Nessas doses, os teores foliares de N e K estiveram acima da faixa de suficiência. Concluiu-se que os compostos orgânicos podem substituir ou reduzir as adubações de cobertura com N e K na fase de pós-plantio do cafeeiro conilon. Conilon coffee trees (Coffea canephora Pierre ex Froenhner) show high yield potential and nutritional requirements. However, due to increase mineral fertilizers costs, the supply of the recommended amounts to be applied is an obstacle for farmers. Thus, the objective of this work was to evaluate the use of two organic compounds in planting of Coffea canephora trees, in order to replace the N and K mineral fertilizer recommended for phase post-planting. The research was realized in greenhouse, in Linhares-ES, Brazil. The experimental design was a completely randomized in a factorial scheme (2x5), with five replications. Each experimental plot consisted of one plant per container (12.8 L). It was evaluated five doses of two organic compounds that were mixed to soil used with substrate. The organic compound 1 (C1) was composed by the mixture of cattle manure and Pennisetum purpureum, and the organic compound 2 (C2) was composed by the mixture of poultry litter and Pennisetum purpureum; both in proportion 1:4. The doses of C1 were 0; 0.853; 1.706; 2.559 and 3.412 kg/container; and the doses of C2 were 0; 0.758; 1.516; 2.274 e 3.032 kg/container. The results showed that both the type of organic compound and the amount applied, interfered on plants growth and in foliar nutrient levels. The highest doses of both compounds retarded the plants development. The doses that provided better dry matter accumulation were 1.623 kg/container (≈ 8.115 kg/hole) of C1 e 1.733 kg/container (≈ 8.665 kg/hole) of C2. At these same doses, the plants showed foliar levels of N and K above the sufficiency range. This way, the organic compounds may be an alternative to replace or reduce the N and K mineral fertilizer recommended for post-planting Coffea canephora trees.  aCattle manure  aCoffea canephora  aPennisetum purpureum Schumach  aPoultry litter  aCafé conilon  aCama-de-frango  aCoffea canephora  aEsterco bovino  aPennisetum purpureum Schumach  aPierre ex Froenhner1 aSILVA, V.
