Resumo: | Nitrogen is the most required and complex management element in maize crop, promoting the highest responses in crop yield. The objective of this work was to verify the effect of different N sources on topdressing in minimum tillage and conventional tillage systems on the agronomic performance of the Pioneer 32R22YHR single cross and on the severity of common rust disease. Two experiments were carried out in a randomized block design (DBC) in the 2013/14 crop in minimum tillage and conventional tillage systems. The treatments were: control without nitrogen, ammonium sulfate, urea, ammonium nitrate, a physical mixture of nitrate (70%) and ammonium sulfate (30%) and a chemical mixture of these same sources in the same proportion just explained. Nitrogen sources had no significant effect on plant height, ear insertion height, ear prolificacy, grain yield and leaf severity of common rust, regardless of the sowing system. Under conventional tillage, the plants presented higher plant height, ear insertion and grain yield. There was no effect of sowing systems on prolificacy. With the exception of nitrogen free treatment, for all others, the severity of common rust was higher in minimum tillage system. |

Objetivou-se com este trabalho verificar o efeito de diferentes fontes de N em cobertura, em sistemas de semeadura em cultivo mínimo e semeadura em preparo convencional do solo, no desempenho agronômico do híbrido simples de milho Pioneer 32R22YHR e na severidade da doença ferrugem comum. Foram implantados dois experimentos em delineamento blocos ao acaso (DBC) na safra 2013/14 em sistemas de semeadura em cultivo mínimo e semeadura em preparo convencional do solo. Os tratamentos foram: testemunha sem N, sulfato de amônio, ureia, nitrato de amônio, uma mistura física de nitrato (70%) e sulfato de amônio (30%) e uma mistura química dessas mesmas fontes na mesma proporção. As fontes de N não tiveram efeito significativo na altura de planta, altura de inserção de espiga, prolificidade, produtividade de grãos e severidade foliar de ferrugem comum, independentemente do sistema de semeadura. Sob sistema de semeadura em preparo convencional do solo, as plantas apresentaram maior altura de planta, inserção de espiga e produtividade de grãos. Não houve efeito dos sistemas de semeadura para a prolificidade. Com exceção do tratamento sem N, para todos os demais, a severidade de ferrugem comum foi maior em sistema de semeadura em cultivo mínimo.Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais - IFSULDEMINAS2020-09-17T20:01:36Z2020-09-17T20:01:36Z2019-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfapplication/pdfPEREIRA, H.
