Resumo: | The objective of this work was to evaluate sugarcane (Saccharum spp.) yield in response to corrective and maintenance phosphorus fertilization in Oxisols. Two experiments were carried out in randomized complete blocks with four replicates. In the corrective fertilization treatments, 150 kg ha-1 P2O5 were broadcast and incorporated before planting. In the maintenance fertilization treatments, 40 kg ha-1 P2O5 per year were applied over the trash blanket. All treatments, except the control, were fertilized with 170 kg ha-1 P2O5 in the planting furrow. The first experiment was carried out in a sugarcane expansion area and the second, in a replanting area, in Oxisols with a low and high phosphorus availability, respectively. In the first experiment, corrective fertilization increased cane yield in 13.4 Mg ha-1 for plant cane and in 14.6 Mg ha-1 for the average of four ratoon crops, whereas maintenance fertilization increased yield in 17.7 and 8.1 Mg ha-1 for the average of four ratoon crops for the treatments without and with corrective fertilization, respectively. In the second experiment, there were no significant differences between treatments regarding yield. Corrective and maintenance phosphorus fertilization should be considered for sugarcane in areas where soil phosphorus availability is limiting. |

Dois experimentos foram conduzidos em blocos ao acaso, com quatro repetições. Nos tratamentos com adubação corretiva, foram aplicados 150 kg ha-1 de P2O5 a lanço, com incorporação antes do plantio. Nos tratamentos de adubação de manutenção, foram aplicados 40 kg ha-1 de P2O5 por ano sobre o palhiço. Todos os tratamentos, exceto o testemunha, foram adubados com 170 kg ha-1 de P2O5 no sulco de plantio. O primeiro experimento foi realizado em área de expansão de cana-de-açúcar e o segundo, em área de reforma, em Latossolos com baixa e alta disponibilidade de fósforo, respectivamente. No primeiro experimento, a adubação corretiva propiciou aumentos na produtividade de colmos de 13,4 Mg ha-1 para cana-planta e 14,6 Mg ha-1 na média de quatro socas, enquanto a adubação de manutenção propiciou aumentos de produtividade de 17,7 e 8,1 Mg ha-1 na média das socas para os tratamentos sem e com adubação corretiva, respectivamente. No segundo experimento, não houve diferenças significativas entre os tratamentos em relação à produtividade. As adubações fosfatadas corretiva e de manutenção devem ser consideradas para cana-de-açúcar em áreas cuja disponibilidade de fósforo do solo é limitante.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGoiasa-Goiatuba Álcool Ltda sugar mill and to its staff.Rein, Thomaz AdolphoSantos Junior, João de Deus Gomes dosSousa, Djalma Martinhão Gomes deCarvalho, Wellington Pereira deLemes, Gabriel de Castro2022-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27054Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02160Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e021601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27054/14958Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/27054Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
