Resumo: | The saline and water stresses are part of the main factors that limit agricultural production. In semi-arid regions, these stresses are potentiated due to high rates of evapotranspiration and low precipitation. However, the supply of water and nutrients via fertilization can favor the maximization of crop production. In this sense, aimed to evaluate the agronomic and nutritional performance of sorghum and millet, submitted to different irrigation blades and increasing nitrogen doses. The research was conducted at Academic Unit of Serra Talhada-PE. The experimental design was a randomized block, arranged in subdivided plots, with four replications, arranged in the 4 x 4 factorial scheme, referring to 4 irrigation blades (28%, 36%, 44%, 52% ETc) and 4 nitrogen doses (0, 100, 200, 300 kg ha-1), adopting the Sorghum + Millet system, being sorghum the main crop. Seeding was carried out on April 7, 2017, with an average of 14 plants per linear. The irrigation blades were based on the ETc (ETc = ETo x Kc of sorghum). Nitrogen fertilization consisted of 1/3 in sowing and 2/3 in covering. Ended each cycle crop, plant height, stem diameter were measured, the number of live leaves was counted, green and dry mass yield was estimated, N-total, Na+, K+ and Cl- content were determined. Data were submitted to analysis of variance and variables adjusted to the regression model, using SAS Software. Nitrogen fertilization and irrigation with saline water benefited the growth of sorghum and millet crop. Nitrogen favors the absorption of N-total and potassium by plants and inhibited the absorption of chloride and sodium. |

En las regiones semiáridas, estas tensiones aumentan debido a las altas tasas de evapotranspiración y la escasez de precipitaciones. Sin embargo, el suministro de agua a través del riego y de nutrientes a través de la fertilización puede favorecer la maximización de la producción de cultivos. En este sentido, el objetivo fue evaluar el rendimiento agronómico y nutricional del sorgo y el mijo, sometidos a diferentes niveles de riego y dosis crecientes de nitrógeno. La envestigación se realizó en la Unidad Académica de Serra Talhada-PE. El diseño experimental fue en bloques al azar, dispuestos en parcelas subdivididas, con cuatro repeticiones, ordenados en el esquema factorial 4 x 4, referido a 4 niveles de riego (28%, 36%, 44%, 52% ETc) y 4 dosis de nitrógeno (0, 100, 200, 300 kg ha-1), adoptando el sistema Sorgo + Mijo, siendo el sorgo el cultivo principal. La siembra se realizó el 7 de abril de 2017, con un promedio de 14 plantas por lineal. Los niveles de riego se basaron en la ETc (ETc = ETo x Kc de sorgo). La fertilización con nitrógeno consistió en 1/3 en siembra y 2/3 en cobertura. Terminado cada ciclo de cultivo, se midió la altura de la planta, el diámetro del tallo, se contó el número de hojas vivas, se estimó el rendimiento de masa verde y seca, se determinó el contenido de N-total, Na+, K+ y Cl- . Los datos se sometieron a análisis de varianza y las variables se ajustaron al modelo de regresión, utilizando el software SAS. La fertilización con nitrógeno y el riego con agua salina beneficiaron el crecimiento de la cosecha de sorgo y mijo. El nitrógeno favorece la absorción de N-total y potasio por las plantas e inhibe la absorción de cloro y sodio.Os estresses salino e hídrico são parte dos principais fatores que limitam a produção agrícola. Em regiões semiáridas, esses estresses são potencializados devido às altas taxas de evapotranspiração e baixa precipitação pluviométricas. Porém, o fornecimento de água por irrigação e nutrientes via adubação pode favorecer a maximização de produção das culturas. Nesse sentido, objetivou-se avaliar o desempenho agronômico e nutricional de sorgo e milheto, submetidos a diferentes lâminas de irrigação e doses crescentes de nitrogênio. A pesquisa foi realizada na Unidade Acadêmica de Serra Talhada-PE. O delineamento experimental foi em blocos casualizados, dispostos em parcelas subdivididas, com quatro repetições, arranjados em esquema fatorial 4 x 4, referentes a 4 lâminas de irrigação (28%, 36%, 44%, 52% ETc) e 4 doses de nitrogênio (0, 100, 200, 300 kg ha-1), adotando o sistema Sorgo + Millet, sendo o sorgo a cultura principal. A semeadura foi realizada em 7 de abril de 2017, com média de 14 plantas por linear. As lâminas de irrigação foram baseadas na ETc (ETc = ETo x Kc do sorgo). A adubação nitrogenada consistiu no parcelamento de 1/3 na semeadura e 2/3 na cobertura. Ao final de cada ciclo da cultura, a altura da planta e o diâmetro do caule foram medidos, o número de folhas vivas foi contado, a produção de massa verde e seca foi estimada, o teor de N-total, Na+, K+ e Cl- foram determinados. Os dados foram submetidos à análise de variância e as variáveis ajustadas ao modelo de regressão, por meio do software SAS. A adubação nitrogenada e a irrigação com água salina beneficiaram o crescimento da cultura do sorgo e do milheto. O nitrogênio favorece a absorção de N-total e potássio pelas plantas e inibe a absorção de cloreto e sódio.Research, Society and Development2021-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1897610.33448/rsd-v10i10.18976Research, Society and Development; Vol. 10 No. 10; e359101018976Research, Society and Development; Vol. 10 Núm. 10; e359101018976Research, Society and Development; v. 10 n. 10; e3591010189762525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/18976/16916Copyright (c) 2021 Denizard Oresca; Alexandre Campelo de Oliveira; Thieres George Freire da Silva; Luiz Guilherme Medeiro Pessoa; Jamiles Carvalho Gonçalves de Souza; Lucas Henrique Macielhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOresca, DenizardOliveira, Alexandre Campelo deSilva, Thieres George Freire da Pessoa, Luiz Guilherme Medeiro Souza, Jamiles Carvalho Gonçalves de Maciel, Lucas Henrique 2021-10-02T21:49:16Zoai:ojs.pkp.sfu.ca:article/18976Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:58.690003Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
