Resumo: Covering plants in corn pre-cropping (Zea Mays) were cultivated in no-tillage system to evaluate soil coverage, phytomass production and N accumulation for the species of covering plants; N supply to corn and crop productivity. The experimental design was made in randomized blocks, with subdivided plots, being the cover plants the main treatments and secondary ones 0 and 120 kg ha-1 of N (NH4NO3) at the time of corn cover fertilization. It was possible to confirm millet (Pennisetum americanum), sun hemp (Crotalaria juncea) and spontaneous vegetation as better cover system; millet produced more phytomass and was more efficient in the soil covering; sun hemp and jack bean (Canavalia ensiformis) presented greater contents of N. In the lack of N fertilization, the following of spontaneous vegetation/corn granted greater N content accumulated in corn straw, in corn grain and biomass; the culture following sun hemp presented the greatest grain production.

O delineamento experimental foi em blocos casualizados, com parcelas subdivididas, sendo as plantas de cobertura os tratamentos principais, e os secundários, 0 e 120 kg ha-1 de N (NH4NO3), na adubação de cobertura do milho. Constatou-se melhor cobertura viva pelo milheto (Pennisetum americanum), Crotalaria juncea e vegetação espontânea (pousio); o milheto produziu mais fitomassa e foi mais eficiente na cobertura morta do solo; a crotalária e o feijão-de-porco (Canavalia ensiformis) apresentaram maiores conteúdos de N. Na ausência de adubação nitrogenada, a sucessão pousio/milho proporcionou maior conteúdo de N acumulado na palhada, no grão e na biomassa do milho; a cultura, em sucessão à crotalária, apresentou maior produção de grãos.Universidade Estadual de Maringá2008-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/139310.4025/actasciagron.v27i3.1393Acta Scientiarum.
