Resumo: | The method of phosphate fertilization is a factor that may affect soil phosphorus availability, directly affecting soybean (Glycine max) yield. Thus, the objective this study evaluated combinations of phosphate fertilization methods on lateral and depth distribution of phosphorus (P) in the soil, as well as soybean yield. Experimental design was randomized blocks, 5x4x8 factorial with split plots, evaluated within each fertilization method: 100% broadcast, 75% broadcast and 25% in the sowing furrow, 50% broadcast and 50% in the row, 25% broadcast and 75% in the sowing furrow, 100% in the sowing furrow and control (No P fertilization), with four replications. The P content was evaluated at the depths 0-5, 5-10, 10-15 and 15-20 cm and in eight lateral distributions every 5 cm (starting between two rows, through the sowing furrow and finishing in the middle of the next row). The method of broadcasting 100% of phosphate fertilization did not present differences in the evaluations of lateral distribution for phosphorus content, however, the methods of phosphate fertilization 75 and 100% in the sowing furrow performed better at the depths 0-5 and 5-10 cm, exactly on central lateral distributions. Increased plant height and soybean yield were observed as the amount of phosphorus increased in sowing furrow instead of broadcast application. |

O objetivo deste estudo foi avaliar combinações dos modos de adubação fosfatada na distribuição lateral e na profundidade de fósforo (P) no solo, assim como a produtividade da soja. O delineamento experimental foi em blocos casualizados, fatorial 5x4x8 com parcelas subdividas, avaliadas dentro de cada modo de adubação: 100% a lanço, 75% a lanço e 25% na linha, 50% a lanço e 50% na linha, 25% a lanço e 75% na linha, 100% na linha e testemunha (sem fertilização P), com quatro repetições. Os teores de P foram avaliados nas profundidades de 0-5, 5-10, 10-15 e 15-20 cm e em oito distribuições laterais em espaçamento de 5 por 5 cm no solo (iniciando na entre linha, passando pela linha de plantio e indo até o meio da próxima entre linha). O modo de adubação fosfatada 100% a lanço não apresentou diferença nas avaliações de distribuição lateral para os teores de P, todavia, os modos de adubação fosfatada 75 e 100% em linha de plantio apresentaram superioridade nas profundidades 0-5 e 5-10 cm, justamente em distribuições laterais centrais. Houve um aumento na altura e produtividade das plantas de soja conforme aumentava-se a quantidade de P na linha de plantio em detrimento a aplicação de P a lanço.EDUFU2017-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3660710.14393/BJ-v34n1a2018-36607Bioscience Journal ; Vol. 34 No. 1 (2018): Jan./Feb.; 88-94Bioscience Journal ; v. 34 n. 1 (2018): Jan./Feb.; 88-941981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/36607/21453Brazil; ContemporaryCopyright (c) 2017 Newton Cabral Barbosa, Hamilton Seron Pereira, Everton Martins Arruda, Elias Brod, Risely Ferraz de Almeidahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBarbosa, Newton CabralPereira, Hamilton SeronArruda, Everton MartinsBrod, EliasAlmeida, Risely Ferraz de2022-02-11T00:52:11Zoai:ojs.www.seer.ufu.br:article/36607Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-11T00:52:11Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
