  This research was accomplished in 2016 at greenhouse for study of different concentration effects of seaweed (Sargassum) extract on qualitative and quantitative characteristics of Menthapiperita. Present research was done in a factorial design with a completely randomized four replications. The main factor was different concentrations of seaweed extract with 0, 10, 20, 30 and 40 percent, while the subplot was different spray time in two period types of every 5 and 10 days. The results showed that the concentration of chlorophyll a in peppermint increased with decreasing the time of foliar application and was not significant at different concentrations of algal extract in 30 and 40% treatments on the studied traits. The effect of different concentrations of sargassum algae extract on plant minerals including nitrogen was positive at a concentration of 20% in 10 days of treatment. Therefore, in order to increase the protein and essential oil of peppermint, the concentrations of sargassum extract in this study can be used. In general, it can be concluded that the use of algae extract in the production of peppermint was not considered appropriate due to reduced growth rate and no positive effect on plant essential oil, and from concentrations of 20% or more as a herbicide can be Used.   Manuscript profile
