Resumo: The efficient use of phosphorus (P) in agriculture has been the main focus of research on this macronutrient. Phosphites, which have been considered plant stimulants, can contribute to increase the efficiency of the use of P by corn. The objective was to evaluate the influence of phosphite via leaf on the growth and accumulation of corn phosphorus in the initial growth phase under doses of P. An experiment was installed in a completely randomized design, in a 5 x 2 factorial scheme with four replications. At 45 days after planting, the plant height and stem diameter, shoot dry matter, stem and roots, contents, accumulation and P and the efficiency of using P (EUP) were evaluated. Phosphorus fertilization of corn, cultivated in chromium Luvisol in the initial stage is essential to increase its growth and the production of dry mass and accumulation of P. The phosphite applied via leaf did not produce additional benefit in growth, biomass production or phosphate nutrition of corn , but increased EUP at the intermediate dose (200 mg dm-3) of this nutrient.

Los fosfitos, que se han considerado estimulantes de las plantas, pueden contribuir a aumentar la eficiencia del uso de P por el maíz. El objetivo fue evaluar la influencia del fosfito a través de la hoja en el crecimiento y la acumulación de fósforo de maíz en la fase de crecimiento inicial bajo dosis de P. Se instaló un experimento en un diseño completamente al azar, en un esquema factorial de 5 x 2 con cuatro repeticiones. A los 45 días después de la siembra, se evaluó la altura de la planta y el diámetro del tallo, la materia seca del brote, el tallo y las raíces, el contenido, la acumulación y el P, y la eficiencia del uso de P (EUP). La fertilización con fósforo del maíz, cultivado en cromo Luvisol en la etapa inicial es esencial para aumentar su crecimiento y la producción de masa seca y acumulación de P. El fosfito aplicado a través de la hoja no produjo un beneficio adicional en el crecimiento, la producción de biomasa o la nutrición de fosfato del maíz. , pero aumentó la EUP a la dosis intermedia (200 mg dm-3) de este nutriente.O uso eficiente de fósforo (P) na agricultura tem sido o foco principal das pesquisas com este macronutriente. Os fosfitos, que têm sido considerados estimulantes de plantas, podem contribuir para aumentar a eficiência do uso de P pelo milho. Objetivou-se avaliar a influência do fosfito via foliar sobre o crescimento e acúmulo de fósforo de milho na fase inicial de crescimento sob doses de P. Um experimento foi instalado em delineamento inteiramente casualizado, em esquema fatorial 5 x 2 com quatro repetições. Aos 45 dias após o plantio foram avaliadas a altura de planta e diâmetro de caule, massa seca de parte aérea, caule e raízes, teores, acúmulo e P a eficiência de utilização de P (EUP). A adubação fosfatada do milho, cultivado em Luvissolo crômico no estádio inicial é fundamental para incrementar seu crescimento e a produção de massa seca e acúmulo de P. O fosfito aplicado via foliar não produziu benefício adicional no crescimento, produção de biomassa ou nutrição fosfata do milho, mas aumentou a EUP na dose intermediária (200 mg dm-3) deste nutriente.Research, Society and Development2020-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/312010.33448/rsd-v9i5.3120Research, Society and Development; Vol. 9 No. 5; e76953120Research, Society and Development; Vol. 9 Núm. 5; e76953120Research, Society and Development; v. 9 n. 5; e769531202525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/3120/5303Copyright (c) 2020 Elidayane Nóbrega Santosinfo:eu-repo/semantics/openAccessVitorino, Plínio José PatriotaSantos, Elidayane da NóbregaRocha, Josinaldo Lopes AraujoMarcelino, Rita Magally Oliveira da SilvaSantos, Leônidas Canuto dos2020-08-20T18:06:36Zoai:ojs.pkp.sfu.ca:article/3120Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:26.396549Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
