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). |
