Resumo: The objective of this work was to determine the effects of autumn-winter soil cover on the response of maize grown in succession in lowland to nitrogenous fertilization in coverage. In Experiment 1, treatments consisted of three systems of soil cover in autumn-winter (cornichão, ryegrass, fallow) and the application of five doses of nitrogen (0, 50, 100, 200, 300 kg ha-1 ) in maize in succession. In Experiment 2, the treatments consisted of two seasons of desiccation of the native serradela and one control, with fallow area during autumn-winter, and four systems of nitrogen fertilization management in cover in maize grown in succession. The management systems consisted of two doses of N in cover (100 and 200 kg ha-1 ), applied at different times. For the two experiments, the experimental design was of randomized blocks, arranged in divided plots, with four replications. Maize in succession to ryegrass produced 7,7 and 11,0% less in relation to succession to the cornichão and fallow. In relation to the autumn-winter fallow, with yield of grains of 8.87 Mg ha-1 , in the average of N management systems, yield of grains grown in succession to the native serradela increased in 12, 6 and 19, 4%, with desiccations carried out at 56 and 14 days before sowing. The agronomic efficiency of N utilization by maize increased with the delay of the native serradela desiccation season and decreased with the increase of the applied N dose.

No Experimento 1, os tratamentos consistiram em três sistemas de cobertura de solo no outono-inverno (cornichão, azevém, pousio) e da aplicação de cinco doses de nitrogênio (0, 50, 100, 200, 300 kg ha-1 ) em cobertura no milho em sucessão. No Experimento 2, os tratamentos constaram de duas épocas de dessecação da serradela nativa e uma testemunha, com área em pousio durante o outono-inverno, e de quatro sistemas de manejo da adubação nitrogenada em cobertura no milho cultivado em sucessão. Os sistemas de manejo constaram de duas doses de N em cobertura (100 e 200 kg ha-1 ), aplicadas em diferentes épocas. Para os dois experimentos, o delineamento experimental utilizado foi de blocos casualizados, dispostos em parcelas divididas, com quatro repetições. O milho em sucessão ao azevém produziu 7,7 e 11,0 % menos em relação, à sucessão ao cornichão e ao pousio. Em relação ao pousio no outono-inverno, com rendimento de grãos de 8,87 Mg ha-1 , na média de sistemas de manejo do N, o rendimento de grãos cultivados em sucessão à serradela nativa aumentou em 12,6 e 19,4 %, com as dessecações realizadas aos 56 e 14 dias antes da semeadura. A eficiência agronômica de uso do N pelo milho aumentou com o atraso da época de dessecação da serradela nativa e diminuiu com o incremento da dose de N aplicado.Departamento de Diagnóstico e Pesquisa Agropecuária.
