Resumo: Antecedent crops, doses and sources of nitrogen on yield compounds of corn. Some plants for mulching have the capacity to increase the availability of nutrients in the soil – nitrogen in particular – for crop succession, thus producing positive effects on the interaction between mineral fertilizer and green manure. As a result, there is a greater possibility to obtain higher incomes than by using each one separately. The objective of this study was to evaluate the effect of antecedent crops, doses and sources of nitrogen on yield compounds and foliar nitrogen content of corn by means of no-tillage system. The experimental design was in randomized blocks with treatments arranged in sub-subdivided plots. These were constituted by crops preceding corn: black oat, wheat, pasture turnip, hairy vetch and one rest treatment during winter. Subplots were established by four doses of nitrogen (0; 50; 100 and 200 kg ha-1 of N), which were applied as cover. Sub-subplots were represented by two sources of nitrogen (ammonia sulfate and urea). Results showed that antecedent crops had some influence upon yield, mass of 1000 grains and foliar nitrogen content of corn. The highest yield of corn was obtained after the winter rest, the pasture turnip and also in the absence of nitrogen fertilization as cover. The maximum yield of corn was obtained when sowing was done after wheat and black oat, in nitrogen doses of 140 and 137 kg ha-1, respectively. The nitrogen sources utilized had some influence only upon the index of harvest, the number of grains per ear and the foliar nitrogen content.

Neste sentido, com o efeito positivo na interação entre adubo mineral e adubação verde, é possível obter rendimentos maiores do que com o emprego de cada um isoladamente. O objetivo deste estudo foi avaliar o efeito das culturas antecessoras, doses e fontes de nitrogênio nos componentes de produção e teor de nitrogênio foliar do milho, no sistema plantio direto. O delineamento experimental foi de blocos casualizados, com os tratamentos dispostos em parcelas subsubdivididas. As parcelas foram constituídas pelas culturas antecessoras ao milho: aveia preta, trigo, nabo forrageiro, ervilhaca peluda e um tratamento representado pelo pousio de inverno. As subparcelas foram constituídas por quatro doses de nitrogênio (0, 50, 100 e 200 kg ha-1 de N), aplicados em cobertura. As subsubparcelas foram representadas por duas fontes de nitrogênio (sulfato de amônio e uréia). As culturas antecessoras influenciaram na produtividade, massa de 1000 grãos e teor de nitrogênio foliar do milho. A maior produtividade do milho foi obtida quando em sucessão ao pousio e nabo forrageiro, na ausência de adubação nitrogenada em cobertura. A máxima produtividade de milho, no sistema plantio direto, foi obtida quando semeada em sucessão ao trigo e aveia preta nas doses de 140 e 137 kg ha-1 de nitrogênio, respectivamente. As fontes de nitrogênio utilizadas influenciaram o número de grãos por espiga e teor de nitrogênio foliar.Universidade Estadual de Maringá2007-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/6610.4025/actasciagron.v29i1.66Acta Scientiarum.
