Resumo: The objective of this study was to evaluate the growth and yield of okra as a function of phosphorus (P) doses and to obtain the critical leaf P content, under the edaphoclimatic conditions of Maranhão (MA), Brazil. The field experiment was carried out from February 15, 2017, to May 9, 2017, in São Luís, MA. The experimental design was randomized blocks, with four replications. The treatments were doses of 0, 80, 160, 240 and 320 kg ha-1 of P2O5, in the form of triple superphosphate, at planting, plus 10 t ha-1 of solid cattle manure. The increase of the P dose increased plant height, leaf dry mass and stem dry mass. With phosphorus supply, flowering occurred earlier than in plants without fertilization. Considering soils with low P content (P(resin) = 11 to 25 mg dm-3) and the minimum recommended organic fertilization for the okra crop of 10 t ha-1 of solid cattle manure, the maximum number of fruits, length of fruit and yield (9960.36 kg ha-1) were obtained with the fertilization of 80 kg ha-1 of P2O5, for the edaphoclimatic conditions of MA, Brazil. The critical leaf P content in okra is 3.4 g kg-1.

O experimento de campo foi realizado no período de 15 de fevereiro de 2017 a 9 de maio de 2017, em São Luís, MA. O delineamento experimental foi de blocos casualizados, com quatro repetições. Os tratamentos foram doses de 0, 80, 160, 240 e 320 kg ha-1 de P2O5, na forma de superfosfato simples, no plantio, mais 10 t ha-1 de esterco bovino sólido. O aumento da dose de P aumentou a altura das plantas, massa seca de folhas e caule. Com o fornecimento de fósforo a precocidade do florescimento foi maior que em plantas não fertilizadas. . Considerando solos com baixo teor de P (P(resina) = 11 a 25 mg dm-3) e a adubação orgânica mínima recomendada para a cultura do quiabo de 10 t ha-1 de esterco bovino sólido, o número de frutos, comprimento do fruto e a produtividade máxima de frutos (9960.36 kg ha- 1) foram obtidos com a adubação de 80 kg ha-1 de P2O5, para as condições edafoclimáticas de MA, Brasil. O teor crítico foliar de P em quiabeiro é de 3,4 g kg-1.  Universidade Federal Rural do Semi-Árido2023-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1140010.1590/1983-21252023v36n225rcREVISTA CAATINGA; Vol. 36 No. 2 (2023); 479-485Revista Caatinga; v. 36 n. 2 (2023); 479-4851983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/11400/11157Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessSouza, Arilson de Jesus FrançaWamser , Anderson FernandoSilva, Vitor Borges daNascimento, Sandra Maria CruzGrangeiro, Leilson da CostaCecílio Filho, Arthur Bernardes2023-07-27T12:06:36Zoai:ojs.periodicos.ufersa.edu.br:article/11400Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:47:03.494037Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
