Resumo: In this study we aimed at evaluating the dry matter production (DMP), nitrogen content (NC) in plant tissues, above ground nitrogen conversion efficiency (ANCE) and above ground nitrogen recovery (ANR) by pearl millet cultivars submitted to different sources of phosphorus and nitrogen doses. The experiment was carried out in 2008 and a completely randomized block design was used in a 2 × 3 × 4 factorial arrangement with four replications. Treatments consisted of three pearl millet cultivars (ADR-7010; ADR-500 and BRS-1501), two sources of phosphorus (simple phosphate and thermo phosphate) at one dose (70 kg.ha-1) and four nitrogen (urea) doses (0; 40; 80 and 160 kg.ha-1). Statistical analysis revealed no significant interactions among variables. ADR-7010 presented (P<0.05) best dry matter production (1175.9 kg.ha-1) amongst cultivars; and simple phosphate showed better result than thermo phosphate. Increasing nitrogen doses led to increased production; harvest succession reduced DMP. There was difference (P<0.05) in NC. Linear NC increase was observed in function of N doses, with maximum value being 42.7 kg of extracted N. The ANCE and ANR decreased with nutrient input, maximum values being 10.7 kg.ha-1 and 33.4%, respectively, in the 40 kg.ha-1 dose. Nitrogen fertilization increased the pear millet cultivars dry matter production.KEYWORDS: crude protein, Pennisetum glaucum, phosphorus, production potential, urea.

O experimento realizado no ano agrícola de 2008 constou de um fatorial 2 × 3 × 4, em arranjo de blocos completos ao acaso, com quatro repetições. Os tratamentos foram constituídos pelos cultivares ADR- 7010; ADR-500 e BRS-1501, pelas fontes de fósforo superfosfato simples (SS) e termofosfato (TF), as quais foram aplicadas na dose de 70 kg.ha-1 e doses de N (0; 40; 80 e 160 kg.ha-¹ sob forma de uréia). A análise estatística revelou ausência de interações significativas entre as variáveis. Entre os cultivares avaliados, a melhor produção (P<0,05) foi a do cultivar ADR-7010 (1175,9 kg.ha-1 de MS), o superfosfato simples apresentou resultados superiores. O incremento de N promoveu aumentos produtivos, a sucessão dos cortes reduziu a produção de MS. Houve diferença (P<0,05) para NC, sendo que, à medida que as doses de N foram elevadas, houve acréscimo linear do NC com valor máximo de 42,7 kg de N extraído. A ECAN e RAN diminuiu em função do acréscimo do nutriente, com valores máximos de 10,7 kg.ha-1 e 33,4% na dose referente a 40 kg.ha-1 de N. A fertilização nitrogenada promoveu incrementos na produção de massa seca dos cultivares de milheto.PALAVRAS-CHAVE: fósforo, Pennisetum glaucum, potencial produtivo, proteína bruta, uréia.Universidade Federal de Goiás2014-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/901010.5216/cab.v15i2.9010Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 15 No. 2 (2014); 119-127Ciência Animal Brasileira / Brazilian Animal Science; v. 15 n. 2 (2014); 119-1271809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/9010/16701https://revistas.ufg.br/vet/article/view/9010/16702da Silva, Alzira GabrielaDe Souza França, Aldi FernandesMiyagi, Eliane SayuriDambros, Carlos EduardoLopes, Fernando Britoinfo:eu-repo/semantics/openAccess2014-06-30T13:37:48Zoai:ojs.revistas.ufg.br:article/9010Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:41.785966Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
