“…In the present study, it was verified that the increase in salinity of the nutrient solution reduced the relative water content of okra plants (Figures 3 and 7A), and its reduction as a function of salinity may occur due to the osmotic effect, which restricts the absorption of water by plants [39]. Similar results have been reported for different vegetables grown in hydroponic systems, such as melon [20], coriander [21], and tomato [40].…”

“…The reduction in Fm may be an indication that there was low efficiency in the quinone photoreduction and electron flow between the photosystems, which results in low PSII activity in the thylakoid membrane, directly influencing the electron flow between the photosystems [59,60]. In addition, the reduction of variable fluorescence may indicate that the photosynthetic apparatus was damaged by salt stress, compromising the photosystem II, with negative effects on the photosynthetic process [21].…”

“…In recent years, studies have reported that foliar application of salicylic acid can mitigate the harmful effects caused by salt stress on several vegetables, such as bell pepper [17], tomato [18], eggplant [19], melon [20], coriander [21], and basil [22]. Okra (Abelmoschus esculentus L.) is an annual vegetable belonging to the Malvaceae family, native to Africa [23].…”

Salinity is one of the most devastating abiotic stresses that limit plant growth and yield, especially in arid and semi-arid regions. The objective of this study was to evaluate the effect of foliar application of salicylic acid in mitigating the effects of salt stress on okra cultivation in a hydroponic system. The study was conducted in a greenhouse, consisting of two experiments. A completely randomized design was adopted in a split-plot scheme, with four levels of electrical conductivity of the nutrient solution—EC (2.1; 3.6; 5.1, and 6.6 dS m−1) considered the plots and four salicylic acid concentrations—SA (0, 1.2; 2.4, and 3.6 mM), the subplots, with four replications. The second experiment differed from the first only by the increase in the EC levels (3.0, 5.0, 7.0, and 9.0 dS m−1). An increase in the electrical conductivity of the nutrient solution negatively affected the physiology and production components of okra. However, foliar application of salicylic acid at concentrations between 1.2 and 2.3 mM reduced the harmful effects of salt stress. The salinity threshold for hydroponic cultivation of okra was 2.54 dS m−1, with a reduction of 7.98% per unit increment in EC above this level.

“…Although water consumption increased with seeding density, doubling seeding density did not imply two times increase in water consumption by the plants in all tested concentrations. The increase in plant density as a strategy to mitigate mass loss per unit area under salt-stress conditions, especially under the bias of water use efficiency, has also been observed for coriander (Ahmadi & Souri, 2018;Vojodi Mehrabanio et al, 2018;Silva et al, 2022).…”

The use of brackish water in semi-arid regions is sometimes necessary, as water is the most limiting factor for agricultural production in these regions. The present study was conducted aiming to evaluate the production of bunches of Coriandrum sativum L., cultivar Tabocas, in hydroponic system plants exposed to nutrient solutions prepared with brackish water, obtained by mixing water from a community dam (electrical conductivity of 9.93 dS m-1) with rainwater. The treatments consisted of four values of electrical conductivity of the nutrient solution (1.49, 3.14, 4.87, and 6.44 dS m-1) and three seeding densities (1.0, 1.5, and 2.0 g of seeds per cell), arranged in a completely randomized experimental design in a 4 × 3 factorial scheme, with three replicates. Plant height was not affected up to the electrical conductivity of the nutrient solution of 6.44 dS m-1 with increasing seeding density. The electrical conductivity of the nutrient solution up to 6.44 dS m-1 at the seeding density of 2.0 g of seed per cell did not affect the shoot fresh and dry mass of the hydroponic coriander, mitigating the deleterious effect of salinity on water use efficiency.
