| description | In recent years, the use of saline water in agriculture has become an alternative mainly because of water scarcity. However, plants do not tolerate high salt contents; so, the use of salt stress attenuators could enable saline water usage in agriculture. This study aimed to assess the effect of saline water and silicon applications on growth, chloroplastid pigments, chlorophyll fluorescence a and beet production. The experiment was conducted with complete randomized blocks in a 5 x 5 combined factorial arrangement according to the Central Composite of Box experiment matrix for the electrical conductivity in the irrigation water (ECw) and silicon doses (Si), with minimum (- α) and maximum (α) values from 0.5 to 6.0 dS m-1 and from 0.00 to 18.16 mL L-1, totaling nine treatments, with four replicates and three plants per plot. The irrigation water ECw increase reduced growth and beet production, but the chlorophyll contents, biomass and fluorescence production were not affected by salinity. Silicon applications via the soil increased growth and chlorophyll fluorescence a but did not reduce the harmful effect of the salt stress. The irrigation water ECw above 0.50 dS m-1 negatively affected the beet crop. The silicon dose of 9.08 mL L-1 is the most recommended application. |

En los últimos años el uso de aguas salinas en la agricultura es una alternativa, principalmente en virtud de la escasez hídrica. Sin embargo, las plantas no toleran altos niveles de sales, por lo que el uso de atenuadores de estrés salino puede ser una estrategia para posibilitar el uso de aguas salinas en la agricultura. En este sentido, este trabajo tiene como objetivo evaluar el efecto de aguas salinas y aplicación de silicio sobre el crecimiento, pigmentos cloroplatísdicos, fluorescencia de la clorofila a y producción de remolacha. El experimento fue conducido en un diseño de bloques al azar, en factorial 5 × 5, referente a cinco niveles de conductividad eléctrica del agua de riego (CEa): (0,5; 1,3; 3,25; 5,2 y 6 dS m-1) y cinco dosis de silicio (0,00; 2,64; 9,08; 15,52 y 18,16 mL L-1), combinadas según la matriz experimental Compuesto Central de Box, con cuatro repeticiones y tres plantas por parcela. El aumento de la conductividad eléctrica en el agua de riego reduce el crecimiento y la producción de remolacha, pero los índices de clorofila, la producción de biomasa y la fluorescencia no están influenciados por el riego con aguas salinas. La aplicación de silicio a través del suelo promueve un incremento en el crecimiento y la fluorescencia de la clorofila a, sin embargo, no reduce el efecto nocivo del estrés salino. La conductividad eléctrica en el agua de riego por encima de 0,50 dS m-1 es suficiente para afectar negativamente el cultivo de la remolacha y la dosis de 9,08 ml L-1 de silicio es la más recomendada para su aplicación.
