In order to determine the effect of seed priming on plant traits of late-spring seeded soybean, field and laboratorial studies were conducted at the Agricultural Research Farm and Laboratory of Razi University, Kermanshah, Iran. In the laboratorial study, soybean seeds were primed with 1% solution each of ammonium, calcium, potassium and sodium nitrate for twenty four hours, at 20°C. Non-primed (control) and hydroprimed (for twenty four hours, at 20°C) seeds were also included in the study for comparison. All seeds were subjected to four different temperatures consisted of 5, 15, 25 and 35°C for 8 days, then seed germination percentage (GP), germination rate (GR) and seedling dry weight (SDW) were measured. In the field study, soybean seeds which primed as explained for the laboratorial study were planted in late spring and plant traits including height, leaf area index (LAI), yield and yield components were evaluated. According to the results obtained from the laboratorial study, GP, GR and SDW were improved when temperature was increased up to 25°C. However, at 35°C soybean seeds failed to germinate. Seed priming significantly improved the soybean plant traits. In both field and laboratorial studies, seeds primed with potassium nitrate showed the highest values for all of the evaluated traits. This treatment increased GP, GR, SDW, height, LAI, the number of pods per plant, the number of seeds per pod, 1000-seed weight and yield 28.3, 129.4, 58.1, 43.4, 47.4, 56.5, 23.8, 6.2 and 44.3%, respectively as compared to control. Although, there were no significant differences between this treatment and the seeds primed with ammonium nitrate for all of the traits under study. Among the priming treatments, the lowest values of the traits were obtained when the seeds primed with sodium nitrate. This study revealed that seed priming can be used as a beneficial method to improve seed performance and plant traits of late-spring seeded soybean
