This study was carried out to determine the effects of different application methods and doses of salicylic acid on the first developmental stages of broad beans grown under salt stress. The experiment was carried out in the plant growth cabinet at Siirt University, Faculty of Agriculture, Department of Field Crops laboratory. During the investigation, the temperature of the working environment was kept at 25±3 °C. Plants were grown in 16 hours of light and 8 hours in the dark period. Three salt concentrations (0, 75 and 150 mM NaCl) and three salicylic acid (SA) concentrations (0, 0.5 and 1.0 mM SA) were applied to the plants through soil and leaves. As a pre-application, 0.5 mM SA and hydropriming were used. According to the results, germination percentage, germination index, mean germination time, stem height, root lenght, stem fresh weight, stem dry weight, root fresh weight, root dry weight and total chlorophyll content varied between 63.33-86.67%, 0.97-2.51, 3.60-6.28 day, 36.11-39.47 cm, 27.50-30.57 cm, 4.404-6.623 g, 0.473-0.555 g, 2.813-3.400 g, 2.813-3.400 g, 0.300-0.396 g and 41.0-50.6%, respectively. While salinity levels did not have a significant impact on germination characteristics, hydropriming application improved germination characteristics, but salicylic acid application had a negative effect. However, it has been observed that salicylic acid applications increase seedling development and dry matter accumulation and promote plant growth under salinity stress. As a result, it has been observed that the application of 0.5 mM salicylic acid is a useful application to improve salinity stress and promote plant growth in broad bean.
