Resumo: This study was conducted with the objective of evaluating the gas exchanges and production components of colored-fiber cotton as a function of irrigation with water of different saline levels and nitrogen (N) doses. The experiment was carried out in drainage lysimeters, filled with eutrophic Regolithic Neosol of sandy loam texture, in the municipality of Campina Grande-PB, Brazil. The statistical design was randomized blocks and the treatments resulted from the combination of five levels of irrigation water electrical conductivity - ECw (5.1, 6.1, 7.1, 8.1 and 9.1 dS m-1) and five N doses - ND (65; 100; 135; 170; 205 mg of N kg-1 of soil) in a 5 x 5 factorial scheme, with three replicates. The interaction between the saline levels of the irrigation water and the N doses did not influence significantly any of the analyzed variables. The gas exchanges and production components of the cotton cultivar 'BRS Rubi' were negatively affected by the ECw higher than 5.1 dS m-1; the CO2 assimilation rate and total number of seeds per plant were the variables most sensitive to the effects of salt stress; N doses above 65 mg kg-1 led to decrease of stomatal conductance in the cotton crop.

O experimento foi desenvolvido em lisímetros de drenagem, preenchidos com um Neossolo Regolítico Eutrófico de textura franco-arenosa, no município de Campina Grande, PB. O delineamento estatístico utilizado foi em blocos casualizados, cujos tratamentos resultaram da combinação de cinco níveis de condutividade elétrica da água de irrigação – CEa (5,1; 6,1; 7,1; 8,1 e 9,1 dS m-1) e cinco doses de nitrogênio – DN (65; 100; 135; 170; 205 mg de N kg-1 de solo) em esquema fatorial 5x5, com três repetições. A interação entre os níveis salinos da água de irrigação e as doses de nitrogênio não influenciaram de forma significativa nenhuma das variáveis analisadas; as trocas gasosas e os componentes de produção do algodoeiro cv. BRS Rubi foram afetadas negativamente pela CEa superior a 5,1 dS m-1; a taxa de assimilação de CO2 e o número total de sementes por planta foram as variáveis mais sensíveis aos efeitos do estressesalino; doses de nitrogênio acima de 65 mg kg-1 promoveu diminuição na condutância estomática do algodoeiro.EDUFU2017-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3710910.14393/BJ-v33n6a2017-37109Bioscience Journal ; Vol. 33 No. 6 (2017): Nov./Dec.; 1495-1505Bioscience Journal ; v. 33 n. 6 (2017): Nov./Dec.; 1495-15051981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/37109/21161Brazil; ContemporaryCopyright (c) 2017 Adaan Sudário Dias, Hans Raj Gheyi, Lauriane Almeida dos Anjos Soares, Reginaldo Gomes Nobre, Francisco Wesley Alves Pinheiro, Geovani Soares de Lima, André Alisson Rodrigues da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDias, Adaan SudárioGheyi, Hans RajSoares, Lauriane Almeida dos AnjosNobre, Reginaldo GomesAlves Pinheiro, Francisco WesleyLima, Geovani Soares de Silva, André Alisson Rodrigues da2022-02-11T21:12:14Zoai:ojs.www.seer.ufu.br:article/37109Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-11T21:12:14Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
