Despite the negative effects of salinity on plants, due to the limited area under cultivation, planting a variety of plants in saline lands is inevitable. Among them, okra is one of the plants that few studies have been done on its response to different levels of salt. Therefore, in order to study the effect of salinity levels on Okra (Abelmoschus esculentus Moench), an experiment was designed based on a randomized complete block design with five treatments including concentration of 0, 50, 100, 150 and 200 mM sodium chloride in three replications at the greenhouse of the faculty of agriculture, Shahid Madani University of Azarbaijan. The results showed that by increasing salinity levels, potassium to sodium ratio, chlorophyll a, relative water content, plant dry weight, number of fruits per plant, fruit weight per plant, number of seeds per plant, seeds weight per plant and 1000 grains weight have decreased but amount of sodium and proline have increased. During the experiment, the plants under 200 mM treatment have died shortly after salinization, but plants under other treatments survived until the end of the experiment and produced the yield. Maintaining high potassium content, low reduction in chlorophyll content and no noticeable change in relative water content were factors that led to continuance of plant growth, dry matter and fruit production at different salt concentrations. Although in terms of number of fruits per plant, there was no significant difference between salinity levels and the control, but a significant decrease in fruit weight per plant was recorded at high salt concentrations, especially under 150 mM, which can be an important factor affecting economic yield of okra in saline environments with EC higher than 10 ds/m.
