Resumo: | This study aimed to evaluate the effects of saline water irrigation and fertilization with different nitrate/ammonium proportions on the contents of nitrogen (N), phosphorus (P), potassium (K+) and sodium (Na+) and Na+/K+ ratio in the sesame cv. CNPA G3, through an experiment conducted in drainage lysimeters under greenhouse conditions, in eutrophic Regolithic Neosol with sandy loam texture, in the municipality of Campina Grande-PB, Brazil. Treatments were distributed in randomized blocks, in 5 x 5 factorial scheme, with three replicates, relative to five levels of irrigation water salinity - ECw (0.6; 1.2; 1.8; 2.4 and 3.0 dS m-1) and five nitrate/ammonium proportions - NAP (200:0, 150:50, 100:100, 50:150, 0:200 mg kg-1 of NO3--N/NH4+-N). Increasing ECw levels caused increment in Na+ contents and reduction in N, P and K+ contents in leaf and stem tissues of the sesame cv. CNPA G3. The increase in the Na+/ K+ ratio in leaves and stem of sesame under irrigation with ECw water up to 3.0 dS m-1 can be considered as a mechanism of tolerance to salt stress. There was interaction between the factors (ECw x NAP) for the N content in the leaf tissues, and its highest accumulation was obtained with ECw of 0.6 dS m-1 and NO3--N/NH4+-N proportion of 200:0 mg kg-1. |

CNPA G3, emexperimento conduzido em lisímetros de drenagem sob condições de casa de vegetação, no Neossolo Regolítico Eutrófico, textura franco-arenosa, no município de Campina Grande, PB. Os tratamentos foram distribuídos em blocos casualizados, em esquema fatorial 5 x 5, com três repetições, referentes a cinco níveis de condutividade elétrica da água de irrigação – CEa (0,6; 1,2; 1,8; 2,4 e 3,0 dS m-1) e cinco proporções de nitrato e de amônio - PNA (200:0, 150:50, 100:100, 50:150, 0:200 mg kg-1 de N-NO3-/N-NH4+). Níveis crescentes de CEa promoveu aumento nos teores de Na+ e diminuição nos teores de N P K nos tecidos foliares e caulinar do gergelim cv. CNPA G3; o aumento na relação Na+/K+ nas folhas e caule do gergelim sob irrigação com água de CEa até 3.0 dS m-1 pode ser considerado como mecanismo de tolerância ao estressesalino; houve interação entre os fatores (CEa x PNA) para teor de nitrogênio nos tecidos das folhas, sendo o maior acúmulo obtido com CEa de 0,6 dSm-1 e proporções de 200:0 mg kg-1 de N-NO3-e N-NH4+.EDUFU2018-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3939710.14393/BJ-v34n5a2018-39397Bioscience Journal ; Vol. 34 No. 5 (2018): Sept./Oct.; 1264-1273Bioscience Journal ; v. 34 n. 5 (2018): Sept./Oct.; 1264-12731981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39397/24215Brazil; ContemporaryCopyright (c) 2018 Adaan Sudário Dias, Geovani Soares de Lima, Hans Raj Gheyi, Reginaldo Gomes Nobre, Leandro de Pádua Souza, Lauriane Almeida dos Anjos Soares, Francisco Wesley Alves Pinheirohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDias, Adaan SudárioLima, Geovani Soares deGheyi, Hans RajNobre, Reginaldo GomesSouza, Leandro de PáduaAnjos Soares, Lauriane Almeida dosPinheiro, Francisco Wesley Alves2022-02-10T12:19:57Zoai:ojs.www.seer.ufu.br:article/39397Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-10T12:19:57Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |

This study aimed to evaluate the effects of saline water irrigation and fertilization with different nitrate/ammonium proportions on the contents of nitrogen (N), phosphorus (P), potassium (K+) and sodium (Na+) and Na+/K+ ratio in the sesame cv. CNPA G3, through an experiment conducted in drainage lysimeters under greenhouse conditions, in eutrophic Regolithic Neosol with sandy loam texture, in the municipality of Campina Grande-PB, Brazil. Treatments were distributed in randomized blocks, in 5 x 5 factorial scheme, with three replicates, relative to five levels of irrigation water salinity - ECw (0.6; 1.2; 1.8; 2.4 and 3.0 dS m-1) and five nitrate/ammonium proportions - NAP (200:0, 150:50, 100:100, 50:150, 0:200 mg kg-1 of NO3--N/NH4+-N). Increasing ECw levels caused increment in Na+ contents and reduction in N, P and K+ contents in leaf and stem tissues of the sesame cv. CNPA G3. The increase in the Na+/ K+ ratio in leaves and stem of sesame under irrigation with ECw water up to 3.0 dS m-1 can be considered as a mechanism of tolerance to salt stress. There was interaction between the factors (ECw x NAP) for the N content in the leaf tissues, and its highest accumulation was obtained with ECw of 0.6 dS m-1 and NO3--N/NH4+-N proportion of 200:0 mg kg-1. |
