Resumo: | Organic management farms in the Federal District, Brazil, usually present overlimed and overfertilized soils, with high content of organic matter and high pH. These conditions lead to a low availability of manganese to crops. Many sweet cassava (Manihot esculenta Crantz.) crops were diagnosed with Mn deficiency in the region, presenting low yields. In order to overcome such condition, an experiment was established comprising the following treatments: application of MnSO4 banded in rows; treatment of cassava cuttings with a MnSO4 solution before planting; application of MnSO4 and elemental sulfur (S0) banded in the rows, to acidify the soil, increasing the Mn solubility; and leaf spraying of a Mn solution. The best results were revealed when the Mn was applied by foliar spraying and using a combination of methods (treatment of cassava cuttings with Mn, and Mn and S0 applied to the soil before planting). This treatments provided a fresh root yield of 19.5 Mg ha-1, contrasting with the control treatment (3.6 Mg ha-1). KEYWORDS: Manihot esculenta Crantz, root production, micronutrients. |

Manganese fertilization for sweet cassava production under organic management systemFertilização com manganês na produção de mandioca de mesa sob sistema de manejo orgânicoOrganic management farms in the Federal District, Brazil, usually present overlimed and overfertilized soils, with high content of organic matter and high pH. These conditions lead to a low availability of manganese to crops. Many sweet cassava (Manihot esculenta Crantz.) crops were diagnosed with Mn deficiency in the region, presenting low yields. In order to overcome such condition, an experiment was established comprising the following treatments: application of MnSO4 banded in rows; treatment of cassava cuttings with a MnSO4 solution before planting; application of MnSO4 and elemental sulfur (S0) banded in the rows, to acidify the soil, increasing the Mn solubility; and leaf spraying of a Mn solution.

KEYWORDS: Manihot esculenta Crantz, root production, micronutrients.Solos de propriedades agrícolas do Distrito Federal sob manejo orgânico normalmente apresentam calagem e fertilizantes em excesso, contendo alto conteúdo de matéria orgânica e elevado pH. Essas condições levam a uma baixa disponibilidade de manganês às culturas. Muitas culturas de mandioca de mesa (Manihot esculenta Crantz.) foram diagnosticadas com deficiência de Mn na região, apresentando baixa produtividade. Para superar essa condição, um experimento foi instalado com os seguintes tratamentos: aplicação de MnSO4 nas linhas de plantio; tratamento das manivas com solução de MnSO4 antes do plantio; aplicação de MnSO4 e enxofre elementar (S0) nas linhas de plantio, para acidificar o solo, aumentando a solubilidade de Mn; e aplicação foliar de uma solução de Mn. Os melhores resultados foram obtidos quando o Mn foi fornecido via foliar e pela combinação de métodos (tratamento de manivas com Mn, e Mn e S0 aplicados ao solo antes do plantio). Esses tratamentos promoveram uma produção de raízes frescas de 19,5 Mg ha-1, contrastando com o tratamento controle (3,6 Mg ha-1).
