Esta publicação, impressa pela Epagri local de Joinville e Cetrevile, visou fornecer informações básicas a um grupo de agricultores que participaram de um evento técnico que ocorreu no Centro de Treinamento de Joinville. Nesta publicação são descritos dois tipos de mangaritos, o mangarito branco (Xanthosoma riedelianum Schott) e o mangarito roxo (Xanthosoma poecile). São relatados: as épocas de plantio, os solos preferenciais, o espaçamento, a possibilidade de consórcios e o preparo para o comércio. |

Andropogon lateralis is a tall and highly plastic tussock-forming grass native from southern South America. It is a frequent component of Campos and Subtropical highland grasslands that often becomes dominant under lax grazing regimes. The aim of this work was to analyze the response of species diversity and forage production of a natural grassland dominated by A. lateralis to a wide range of grazing intensity. We hypothesized that species diversity and forage production would both peak at the intermediate canopy heights determined by grazing regimes of moderate intensity. A grazing experiment was conducted in a highland grassland with mesothermal humid climate at 922 masl (Atlantic Forest biome, Santa Catarina state, Brazil) that comprised 87 species from 20 families but had 50% of its standing biomass accounted by A. lateralis. Four pre-/post-grazing canopy heights?12/7, 20/12, 28/17, and 36/22 cm (measured on A. lateralis)?were arranged in a complete randomized block design with four replications, and intermittently stocked with beef heifers from October 2015 to October 2017. Andropogon lateralis cover decreased (from 75 to 50%), and species richness increased (15?25 species m-2) as canopy height decreased. Grazing intensity did not affect annual forage production (4.2 Mg DM ha-1). This natural grassland dominated by A. lateralis had a high capacity to adjust to grazing regimes of contrasting intensity, maintaining forage production stable over a wide range of canopy heights. However, to prevent losses in floristic diversity, such grassland should not be grazed at canopy heights higher than 28 cm.
