Resumo: In order to evaluate the effects of phosphorus, potassium and magnesium application on the nutrient absorption and yield of yam bean (Pachyrhizus erosus (L.) Urban), in a Yellow Latosol of the Zona da Mata of Pernambuco State, Brazil, an experiment was carried out using the strain of Bradyrhizobium sp. NFB 450, isolated from yam bean and selected for efficient N2 fixation in previous experiments. Potassium and magnesium were applied in the proportion of 2:1 (K2O:MgO) in increasing levels (0:0, 40:20, 60:30 and 80:40 kg ha-1 of K2O and MgO, respectively), and crescent levels of phosphorus (0, 20, 40, 60 and 80 kg ha-1 of P2O5) were added in the form of triple superphosphate. Maximum dry matter production, total N and total P accumulated were obtained when applying 64 kg ha-1 of P2O5. A significant effect of K2O:MgO levels was observed in relation to the treatment without K and Mg application; nevertheless, higher levels of K2O:MgO decreased dry matter and total N, and increased total P accumulation. Yam bean responded to low levels of P, K and Mg fertilizer, and showed ability in N2 fixation, with great potential for biomass production.

Urban) cultivado em um Latossolo Amarelo distrófico álico da Zona da Mata de Pernambuco, foi conduzido um experimento inoculando as sementes com a estirpe de Bradyrhizobium sp. NFB 450. Foram aplicadas quatro fórmulas de adubação com potássio e magnésio, na proporção (K2O:MgO) 2:1, em quantidades crescentes (0:0, 40:20, 60:30 e 80:40 kg ha-1 de K2O e MgO, respectivamente) e cinco níveis de fósforo (0, 20, 40, 60 e 80 kg ha-1 de P2O5, na forma de superfosfato triplo). A produção máxima foi obtida quando aplicou-se 64 kg ha-1 de P2O5. Observou-se efeito significativo para os níveis de K2O-MgO, quando em comparação com o tratamento sem K e Mg; entretanto, com o aumento da aplicação verificou-se diminuição da produção de matéria seca e do N total, e aumento do P total acumulado na parte aérea. O jacatupé respondeu a níveis baixos da fertilização com P, K e Mg, e mostrou-se efetivo na fixação do N2, com grande potencial na produção de biomassa.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraStamford, Newton PereiraSantos, Carolina Etiene de Rosália e SilvaMedeiros, RuiFreitas, Ana Dolores Santiago de1999-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5513Pesquisa Agropecuaria Brasileira; v.34, n.10, out. 1999; 1831-1838Pesquisa Agropecuária Brasileira; v.34, n.10, out. 1999; 1831-18381678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5513/2704info:eu-repo/semantics/openAccess2012-02-13T11:38:31Zoai:ojs.seer.sct.embrapa.br:article/5513Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-02-13T11:38:31Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
