Resumo: | The use of saline waters in agriculture has become an alternative for the expansion of irrigated agriculture in the semiarid regions. However, it is necessary to develop techniques capable of mitigating the effects of stress caused by excess salts on plants. In this context, the objective of present study was to evaluate the growth and production of cotton cv. BRS Jady irrigated with waters of increasing levels of salinities and doses of organic fertilization. The experiment was conducted using a Regolith Neosol of a sandy-loamy texture in a greenhouse in the municipality of Campina Grande – PB. The experimental design was a randomized block design, in a 4 x 4 factorial scheme, with three replications, being the treatments composed of four levels of electrical conductivity of water (ECw, 1.7, 3.4, 5.1 and 6, 8 dS m-1) and four doses of organic fertilization (0, 2.5, 3.5 and 4.5% on the basis of soil volume). Water salinity of up to 6.8 dS m-1 reduces relative growth rates, specific leaf area, leaf area ratio and harvest index of cotton cv. BRS Jady. Organic fertilization attenuates the effects of irrigation water salts on the net assimilation rate and total dry mass of cotton cv. BRS Jady, with a dose of 4.5% MO showing the best results. |

Sin embargo, es necesario desarrollar técnicas capaces de paliar los efectos del estrés provocado por el exceso de sales en las plantas. Dado lo anterior, el objetivo fue evaluar el crecimiento y producción de algodón cv. BRS Jady bajo riego con agua salina y diferentes dosis de abono orgánico. Se utilizó un diseño de bloques completos al azar, en un esquema factorial 4 x 4, con tres repeticiones, estando los tratamientos compuestos por cuatro niveles de conductividad eléctrica del agua - CEa (1.7; 3.4; 5.1 y 6, 8 dS m-1) y cuatro dosis de materia orgánica - MO (0; 2.5; 3.5 y 4.5% basado en el volumen del suelo). La salinidad del agua de hasta 6,8 dS m-1 reduce las tasas de crecimiento relativo, el área foliar específica, la proporción del área foliar y el índice de cosecha del algodón cv. BRS Jady. La fertilización orgánica atenúa los efectos de las sales del agua de riego sobre la tasa de asimilación neta y la masa seca total del algodón cv. BRS Jady, con una dosis de 4.5% MO mostrando los mejores resultados.A utilização de águas salinas na agricultura tornou-se uma alternativa para expansão da agricultura irrigada nas regiões semiáridas. Contudo é necessário o desenvolvimento de técnicas capaz de amenizar os efeitos do estresse ocasionado pelo excesso de sais sobre as plantas. Diante do exposto, objetivou-se avaliar o crescimento e produção do algodoeiro cv. BRS Jady sob irrigação com água salinizada e diferentes doses de adubação orgânica. Usou-se delineamento experimental de blocos ao acaso, em esquema fatorial 4 x 4, com três repetições, sendo os tratamentos compostos de quatro níveis de condutividade elétrica da água – CEa (1,7; 3,4; 5,1 e 6,8 dS m-1) e quatro doses de matéria orgânica – MO (0; 2,5; 3,5 e 4,5% em base do volume de solo). A salinidade da água de até 6,8 dS m-1 reduz as taxas de crescimento relativo, área foliar especifica, razão de área foliar e o índice de colheita do algodoeiro cv. BRS Jady. A adubação orgânica atenua os efeitos dos sais da água de irrigação na taxa de assimilação liquida e fitomassa seca total do algodoeiro cv. BRS Jady, com a dose de 4,5 % MO apresentando os melhores resultados.Editora Verde2021-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/922310.18378/rvads.v16i4.9223Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 16 No. 4 (2021); 393 - 400Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 16 Núm. 4 (2021); 393 - 400Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 16 n. 4 (2021); 393 - 4001981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/9223/10996Copyright (c) 2021 Leandro de Pádua Souza et al.info:eu-repo/semantics/openAccessSouza, Leandro de Pádua Fatima, Reynaldo Teodoro de Lacerda, Cassiano Nogueira de Soares, Lauriane Almeida dos Anjos Silva, André Alisson Rodrigues da Veloso, Luana Lucas de Sá Almeida 2022-10-19T14:41:01Zoai:ojs.gvaa.com.br:article/9223Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:47.912666Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
