Abstract
O objetivo deste trabalho foi avaliar o efeito da inoculação de Bradyrhizobium em pré-semeadura de soja e o efeito do tratamento das sementes com fungicidas na nodulação. Foram usados controles sem inoculação, que receberam ou não a aplicação de 200 kg ha-1 de N. A inoculação em pré-semeadura mostrou desempenho igual à inoculação padrão quanto à nodulação, produção de matéria seca, produtividade de grãos e acúmulo de nitrogênio nos tecidos e grãos da soja. Entretanto, quando as sementes foram tratadas com fungicidas, houve redução da nodulação e da produtividade.
The objective of this work was to evaluate the effect of Bradyrhizobium inoculation on soybean pre-sowing and the effect of the treatments of seeds using fungicides on nodulation. Control treatments consisted of two non-inoculated treatments, with or without N-fertilizer supply (200 kg ha-1 of N). Inoculation at pre-sowing had a performance similar to the standard inoculation at sowing regarding soybean nodulation, dry matter production, grain yield and N accumulation in tissues and grains. However, when seeds were treated with fungicides, nodulation and grain yield decreased.
