Resumo: The proper management of irrigation and mineral nutrition is critical to the success of crops, especially crops grown under salt stress conditions. The objective of this study was to evaluate the production and oil content of castor plants (Ricinus communis L.) irrigated with brackish water with different salinity levels (0.6, 1.6, 2.6, 3.6, and 4.6 dS m-1) and grown under different nitrogen levels (50, 75, 100, 125, and 150 mg of N kg-1 soil). These treatments were arranged in a completely randomized block design with a 5 ? 5 factorial scheme and three repetitions, totaling 75 experimental units. The interaction effect between salinity levels and nitrogen levels affected fruit weight per plant and oil content, and irrigation with brackish water with an electrical conductivity starting at 0.6 dS m-1 reduced the number of racemes per plant, number of fruits, and the weight of fruits and seeds.

Neste viés, o objetivo do presente estudo foi avaliar a produção e teor de óleo da mamoneira (Ricinus communis L.) irrigada com águas salobras (0,6; 1,6; 2,6; 3,6 e 4,6 dS m-1) sob aplicação de doses de adubação nitrogenada a base de ureia (50, 75, 100, 125 e 150 mg de N kg-1 de solo). Estes tratamentos foram distribuídos em blocos inteiramente casualizados, analisados em esquema fatorial 5 x 5, com três repetições, totalizando 75 unidades experimentais. A interação salinidade vs nitrogênio influenciou o comportamento do peso dos frutos por planta assim como o seu teor de óleo, e a aplicação de água salobra via irrigação com condutividade elétrica a partir de 0,6 dS m-1 provocou reduções no número de racemos e frutos por planta, peso dos frutos e de sementes.UEL2019-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3172910.5433/1679-0359.2019v40n6Supl2p2851Semina: Ciências Agrárias; Vol. 40 No. 6Supl2 (2019); 2851-2860Semina: Ciências Agrárias; v. 40 n. 6Supl2 (2019); 2851-28601679-03591676-546Xreponame:Semina.
