Resumo: In the Brazilian semi-arid region, it is common to find water with high concentration of salts and with variation in its cationic nature. Thus, we aimed to evaluate the growth and production components of sunflower, cv. BRS 324, as a function of irrigation water of different salinity levels and cationic nature associated with doses of nitrogen (N). The experiment was conducted in pots, under open field conditions, in the municipality of Campina Grande-PB, Brazil, in a randomized block design in 5 x 5 factorial scheme, with three replicates, based on five treatments of salinity and cationic nature of the water - S (S1 - Control; S2 - NaCl; S3 - CaCl2; S4 - KCl and S5 - NaCl+CaCl2+MgCl2) combined with five N doses (50; 75; 100; 125 and 150 mg of N kg-1 of soil). Irrigation was performed using water with electrical conductivity - ECw of 0.5 dS m-1 for the control and 5.0 dS m-1 for the other treatments. The growth and production of sunflower cv. BRS 324 were reduced when the crop was irrigated with water of electrical conductivity of 5.0 dS m-1, independent of the cationic nature of water; nitrogen fertilization did not attenuate the deleterious effects of salt stress caused by irrigation waters of 5.0 dS m-1 on sunflower cv. BRS 324; The methods of comparison of means through contrasts and Tukey's test were efficient and can be used together to evaluate the growth and the production of sunflower.

Neste sentido, objetivou-se com este trabalho, avaliar o crescimento e oscomponentes de produção do girassol cv. BRS 324, em função da irrigação com água de diferentes salinidades e natureza catiônica associada a doses de nitrogênio, em experimento conduzido em vasos, sob condições abertas de campo, no município de Campina Grande, PB, no delineamento de blocos ao acaso, em esquema fatorial 5 x 5, com três repetições, sendo cinco tratamentos de salinidade e natureza catiônica da água - S (S1 - Testemunha; S2 - NaCl; S3 - CaCl2; S4 - KCl e S5 – NaCl+CaCl2+MgCl2) combinados com cinco doses de nitrogênio (50; 75; 100; 125 e 150 mg de N kg-1 de solo). Utilizou-se na irrigação, água com condutividade elétrica – CEa de 0,5 dS m-1 para a testemunha (S1) e 5,0 dS m-1 para os demais tratamentos. O crescimento e a produção do girassol cv. BRS 324 foram reduzidos quando a cultura é irrigada com água de condutividade elétrica de 5,0 dS m-1, independente da natureza catiônica da água; a adubação nitrogenada não atenuou os efeitos deletérios do estresse salino causado por irrigação com água de 5,0 dS m-1 sobre o girassol cv. BRS 324. Os métodos de comparação de médias através de contrastes e teste de Tukey foram eficientes e podem ser utilizados em conjunto para avaliar o crescimento e a produção de girassol.EDUFU2017-05-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3653410.14393/BJ-v33n3-36534Bioscience Journal ; Vol. 33 No. 3 (2017): May/June; 581-591Bioscience Journal ; v. 33 n. 3 (2017): May./June; 581-5911981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/36534/20317Brazil; ContemporaryCopyright (c) 2017 José Raimundo de Sousa Júnior, Geovani Soares de Lima, Vera Lúcia Antunes de Lima, Hans Raj Gheyi, Jônatas Raulino Marques de Sousa, Elysson Marcks Gonçalves Andrade, Lauriane Almeida dos Anjos Soareshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSousa Júnior, José Raimundo deLima, Geovani Soares deLima, Vera Lúcia Antunes deGheyi, Hans RajSousa, Jônatas Raulino Marques deAndrade, Elysson Marcks GonçalvesSoares, Lauriane Almeida dos Anjos2022-02-15T20:05:48Zoai:ojs.www.seer.ufu.br:article/36534Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-15T20:05:48Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
