Resumo: To evaluate the influence of topdressed nitrogen application time (stages 1, 2, and 3) and sources (urea, ammonium sulfate, and Entec® + control), on double-cropped corn yield after soybean, the experiment was conducted at Ivani Farm, Santa Carmem, Mato Grosso State, Brazil (12°00’S, 55°14’W, altitude 365 m), in the 2008 growing season. The treatments were arranged in a randomized complete block design, as a 3x4 factorial scheme (time of application x source of nitrogen), with four replications. The source x time interaction was not significant for any of the characters measured, indicating that these factors were independent. The application at stage 3 (ten expanded leaves) provided the greatest spike diameter, length of grain, rows of grains per spike, and grain yield, while spike length, cob diameter, prolificacy, and weight of hundred grains were not affected by times of N application. Regarding N sources, they only affected spike length, cob diameter, and grain yield, as compared to control. No significant differences were observed among N sources. Nitrogen application influenced positively the corn performance double-cropped after soybean. KEY-WORDS: Zea mays L.; urea; ammonium sulfate; ammonium sulfonitrate; nitrogen fertilizing; no-tillage.

Com o objetivo de avaliar a influência de épocas de aplicação (estádios 1, 2 e 3) e fontes de nitrogênio (uréia, sulfato de amônio e Entec® + testemunha), em cobertura, no milho de segunda safra cultivado em sucessão à soja, sobre o desempenho produtivo da cultura, conduziu-se o experimento no Sítio Ivani, Santa Carmem, MT (12°00’S, 55°14’W e altitude de 365 m), no ano agrícola de 2008. Os tratamentos foram dispostos em delineamento experimental de blocos ao acaso, em esquema fatorial 3x4 (época de aplicação x fonte de nitrogênio), com quatro repetições. A interação época x fonte não foi significativa para nenhum dos caracteres mensurados, demonstrando que estes fatores comportam-se de maneira independente. A aplicação no estádio 3 (dez folhas completamente expandidas) proporcionou maior diâmetro de espiga, comprimento de grão, fileiras de grãos por espiga e produtividade de grãos, enquanto o comprimento de espiga, diâmetro de sabugo, prolificidade e massa de cem grãos não foram influenciados pelas épocas de aplicação de nitrogênio. As fontes influenciaram apenas o comprimento de espiga, diâmetro de sabugo e produtividade de grãos, em comparação à testemunha, sendo que, entre as fontes, não se observou diferença significativa. A aplicação de nitrogênio influencia, positivamente, o desempenho produtivo do milho, na segunda safra em sucessão à soja.
