In order to improve growth and yield of medicinal and aromatic plants, the application of natural substances has been increased in recent years. In this study, the effects of different fertilizers under the foliar spray of l-phenylalanine on growth and physiological characteristics and essential oil content of hyssop [Hyssopus officinalis L. subsp. Angustifolius (Bieb.)], as one important medicinal and aromatic plants, at field condition in southwestern Iran were investigated in a 2-year study (2016 and 2017). Experimental treatments were including arbuscular mycorrhizal fungi, chemical (N.P.K), manure, and vermicompost fertilizers with the control in the main plots and as well as three levels of the foliar application of l-phenylalanine in sub plots. Results indicated that the application of organic/biological fertilizers along with l-phenylalanine spraying have beneficial and effective role in improving the growth characteristics, shoot performance, photosynthetic pigments, and active substances of hyssop. Hence, l-phenylalanine spraying effects on improving arbuscular mycorrhizal fungi symbiosis and the application of manure and vermicompost can be a promising strategy in achieving organic production of medicinal plants such as hyssop.
