Abstract :Irregularities in precipitation due to climate change in recent years cause various adverse conditions in soils. Plants growing in these soils are affected by these adverse conditions and create mechanisms against these adversities. In this study, the resistance to salt stress was investigated as a result of the application of ultrasonic sound waves before sowing to bean seeds under salt stress. Salt stress was created by using NaCl salt at 0, 5, 10 and 15 dS m-1 levels. Ultrasonic sound waves were applied at 50 Hz for 20 min in an ultrasonic sound waves device. The study was established in the laboratory of Isparta University of Applied Sciences Faculty of Agriculture, Department of Field Crops with 3 replicates in completely randomized design. In the study, germination (germination rate, average germination time, germination index, vigour index), seedling development (seedling length, root length, dry matter content and salinity tolerance index) were examined in plants grown under stress conditions. When the results were analysed, ultrasonic sound waves had a stimulating effect on non-stressed plants and also increased the salt tolerance of bean plants under 5 and 10 dS m-1 salt stress. Except for average germination time and dry matter content, ultrasonic sound wave treatments had positive effects on all traits examined. The results of the study showed that the negative effects of salt stress in beans can be reduced by the application of ultrasonic sound waves.
