Resumo: | The introduction of indeterminate habit soybean cultivars expanded the possibilities of rotation or succession crops in producing areas of the Cerrado region, but it represents a less well-known component in the management of soil fertility. The objective of this work was to verify the agronomic and economic response of indeterminate habit soybean to the variations in NPK fertilization of sowing and potassium at topdressing in an improved fertility Latosol in Campos das Vertentes (MG). The experimental design was in randomized blocks, with subdivided plots in three replications. In plots, the treatments consisted of doses of 315 and 485 kg ha-1 of NPK 02-30-10 formulation in the sowing furrow and, in the subplots, the application of 0, 15, 30 and 45 kg ha-1 of K2O in topdressing at 21 days after sowing was tested. There is no significant difference in the variation of sowing fertilization, but productivity increases linearly by the additional input of potassium at topdressing. Soybean cultivar requires more K2O in maintenance fertilization in soil of improved fertility to express productive potential near 4 t ha-1, which is economically rewarding. |

O objetivo deste trabalho foi verificar a resposta agronômica e econômica da soja de hábito indeterminado a variações na adubação NPK de semeadura e cobertura potássica num Latossolo Vermelho de fertilidade construída nos Campos das Vertentes (MG). O delineamento experimental foi em blocos casualizados, com parcelas subdivididas, em três repetições. Nas parcelas os tratamentos consistiram de doses de 315 e 485 kg ha-1 do formulado NPK 02-30-10 no sulco de semeadura, e nas subparcelas testou-se a aplicação de 0, 15, 30 e 45 kg ha-1 de K2O em cobertura aos 21 dias após a semeadura. Não há diferença significativa na variação da adubação de semeadura, mas a produtividade aumenta linearmente pelo aporte adicional de potássio em cobertura. A cultivar de soja requer mais K2O na adubação de manutenção em solo de fertilidade construída para expressar potencial produtivo próximo de 4 t ha-1, o que é economicamente compensador.Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais2018-06-11T17:17:46Z2018-06-11T17:17:46Z2017-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfHICKMANN, C. et al.
