Resumo: Phosphorus (P) is one of the most limiting mineral elements for biomass and grain production in tropical soils. This study was undertaken to assess the influence of P on herbage accumulation (DM) and the nutritive value of forage sorghum (Sorghum bicolor) and black oat (Avena strigosa) in succession. Evaluated treatments were P fertilization levels of 0, 50, 100, 150 and 200 kg of P2O5 ha-1 distributed in a randomized complete block design with three replicates. The treatments were applied at sorghum seeding in the summer 2010/2011 and 2011/2012. Black oat was seeded following sorghum in 2011 with no additional P fertilization. Herbage production and its nutritive value were assessed by successive cuts. The greatest sorghum DM yields were obtained at the highest phosphate level tested (200 kg P2O5 ha-1), with residual response in subsequent black oat. There was no effect of P fertilization levels on the nutritive values of both crops, considering crude protein (CP) levels, in vitro dry matter digestibility (IVDMD), neutral detergent fiber (NDF) and acid detergent fiber (ADF), what demonstrates that P addition has no effect in forage nutritive value, especially when the soil P levels are classified as medium or high. The plant P recovery efficiency decreased when increasing P fertilization levels for both sorghum and black oat. The level of 50 kg P2O5 ha-1 year-1 presented the greatest P recovery by plants, which supports the idea of less fertilizer use with more efficiency.

Este estudo teve como objetivo avaliar a influência do P na produção de matéria seca (MS) e no valor nutritivo do sorgo forrageiro (Sorghum bicolor) e da aveia preta (Avena strigosa) em sucessão. Os tratamentos foram constituídos com doses de P nos níveis de: 0, 50, 100, 150 e 200 kg de P2O5 ha-1 distribuídos em um delineamento em blocos casualizados com três repetições. Os tratamentos foram aplicados no momento da semeadura, na cultura do sorgo no verão 2010/2011 e 2011/2012. A aveia foi semeada após o sorgo em 2011, sem a aplicação de P. A produção de forragem e o valor nutritivo das culturas foram avaliados por cortes. As maiores produções de MS do sorgo foram obtidas quanto foi aplicado a maior dose do fosfato (200 kg P2O5 ha-1), com uma resposta residual na cultura subsequente da aveia preta. Não houve efeito dos níveis de P nos valores nutritivos de ambas as culturas, tanto nos teores de proteína bruta (PB), como na digestibilidade in vitro da matéria seca (DIVMS), na fibra em detergente neutro (FDN) e na fibra em detergente ácido (FDA), demonstrando que a utilização de fertilizantes fosfatados não tem efeito no valor nutritivo das forragens, especialmente quando os níveis de P do solo estão médios a altos. A eficiência de recupera ção P pelas plantas diminuiu quando as doses de P aumentaram tanto no sorgo como na aveia preta. A dose de 50 kg de P2O5 ha-1 ano-1 foi a que apresentou a maior recuperação de P pelas plantas, apoiando a ideia sob uma menor utilização de fertilizantes com maior eficiência.UEL2017-03-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de CampoPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2560610.5433/1679-0359.2017v38n1p429Semina: Ciências Agrárias; Vol. 38 No. 1 (2017); 429-442Semina: Ciências Agrárias; v. 38 n. 1 (2017); 429-4421679-03591676-546Xreponame:Semina.
