Resumo: Manure, if managed and used properly, is a good source of nutrients for crop production, andnitrogen is the most important plant nutrient to improve forage production. The objective of this study was to compare forage production of winter species (black oat + italian ryegrass) and summer species (sorghum or pearl millet) in sequencial cropping with organic and mineral nitrogen fertilizer. The treatments consisted of a combination of two nitrogen sources: ammonium nitrate and pig slurry, with four levels of N (zero, 60, 120 and180kg/ha), applied at the plant sowing or after the first cut. Two cuttings were made to determine dry matter yield. Results indicate that both sources of N increased dry matter yield and there was no difference between the two sources. The maximum dry matter yield with winter grasses (black oat + italian ryegrass) was obtained with doses of N between 150 and 160 kg/ha. With summer annual grasses, the response to N was linear up tothe level of 180kg/ha.

Entre os nutrientes essenciais, o nitrogênio é exigido em maior quantidade pelas gramíneas, sendo normalmente o principal responsável pelo aumento de produtividade. Este estudo teve por objetivo avaliarfontes e doses de N em gramíneas forrageiras de inverno (aveia-preta + azevém) e de verão (sorgo forrageiro e milheto) cultivadas em sucessão. Os tratamentos constaram de duas fontes de N, nitrato de amônio e esterco de suínos, aplicadas nas doses de zero, 60, 120 e 180kg de N/ha, em duas épocas: na semeadura da cultura e após o primeiro corte. Houve resposta das forrageiras às doses de N aplicadas, sem diferença entre fontes. O rendimento máximo de matéria seca das gramíneas de inverno (aveia-preta + azevém) foi alcançado com a aplicação entre 150 e 160kg/ha de N. No caso das gramíneas tropicais (sorgo e milheto), a resposta à adubação foi em geral linear até os 180kg/ha de N aplicados.
