Uso de compostos orgânicos no plantio do cafeeiro conilon

Use of organics compounds in the planting coffee conilon trees 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
