Resumo: | The common bean and maize have presented significative responses to phosphate fertilizer, but it is necessary to evaluate the soil P availability to recommend P fertilization. The objective of this work was the calibration of Mehlich-1, Mehlich-3 and Ion-exchange Resin methods, through the relations between soil P availability and the crops grain yield, as well as the evaluation of the response of common bean to P row application. The treatments consisted of 250, 500 and 1.000 kg ha-1 P2O5 broadcasting, cultivating four crops of common bean 'Carioca' in rotation with maize 'BR 201'. For the last common bean crop, the splitted plots received 0, 75, 150 and 300 kg ha-1 P2O5 in row. The grain yield increased with phosphate levels, being linear for common bean up to 1.000 kg ha-1 P2O5, and quadratic for maize. The three methods presented a good capacity to predict the soil P availability, with significative correlation among themselves. The soil P critical level to obtain 80% of maximum grain yield for corn was 10, 14 and 17 mg dm-3, respectively for Mehlich-1, Mehlich-3 and Resin methods. The common bean presented a significative response to phosphate fertilizer in row, which magnitude depended on the previous soil P availability. |

O objetivo deste trabalho foi calibrar os métodos Mehlich-1, Mehlich-3 e Resina, pela relação entre teores de P extraídos do solo com produtividade das culturas de feijão e milho, e avaliar a resposta do feijoeiro à adubação fosfatada no sulco. Os tratamentos constituíram-se de 250, 500 e 1.000 kg ha-1 de P2O5 aplicados a lanço, obtendo-se quatro cultivos de feijão 'Carioca' em rotação com milho 'BR 201'. No último cultivo do feijão, as parcelas subdivididas receberam 0, 75, 150 e 300 kg ha-1 de P2O5 no sulco. As produtividades aumentaram com a adubação fosfatada, sendo linear em relação ao feijão até 1.000 kg ha-1 de P2O5, e quadrática em relação ao milho. Os três métodos apresentaram boa capacidade de predição da disponibilidade de P no solo, e mostraram correlação significativa entre si. O nível crítico de P para obter 80% do rendimento máximo para o milho foi de 10, 14 e 17 mg dm-3, respectivamente, pelos métodos Mehlich-1, Mehlich-3 e Resina. O feijão apresentou resposta significativa à adubação fosfatada no sulco, variando com a disponibilidade de P existente no solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Miranda, Leo Nobrede Azevedo, Juscelino Antoniode Miranda, Jeanne Christine ClaessenGomes, Antonio Carlos2002-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6510Pesquisa Agropecuaria Brasileira; v.37, n.11, nov. 2002; 1621-1627Pesquisa Agropecuária Brasileira; v.37, n.11, nov. 2002; 1621-16271678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6510/3567info:eu-repo/semantics/openAccess2010-08-23T12:22:35Zoai:ojs.seer.sct.embrapa.br:article/6510Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-23T12:22:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
