The quality of the seeds of medicinal plants is an important factor in their growth and development and yield under field conditions. Therefore, the methods for improving their vigor such as the priming especially with micronutrients required for the germination is an important factor in enhancing their yield. The objective of the present study was to examine the effect of seed priming with different concentrations (0, 0.5, 1.0, 1.5, 2.0 and 2.5%) of micronutrients (Fe, Zn, B, Mn) on the growth and yield characteristics of plantain. It was found that seeds primed with 1.0, 1.5, 2.0 and 2.5% Zn significantly increased leaf area. Their priming with 1.5, 2.0 and 2.5% Fe resulted in the highest leaf area. Under the priming with Mn, the highest leaf area was obtained with the concentrations of 1.0, 1.5, 2.0 and 2.5%. Total biomass was increased with Zn, Fe and Mn treatment and was decreased with B treatment. Furthermore, the application of Fe, Zn and Mn at the concentrations of 0.5, 1.0 and 1.5% significantly increased seed yield. The highest coefficient of seed expansion was related to Zn concentrations of 1.5 and 2.0% and Fe concentrations of 2.0 and 2.5%. Given the results and the importance of seed yield and coefficient of mucilage expansion, it is recommended to prime plantain seed with 1.5% Zn, Fe and Mn and to avoid their priming with B.
