Abstract :
An increasing approach to the use of medicinal herbs globally highlights the importance of cultivating these plants. In this regard, the effect of organic and acidic fertilizers on Morphological and Physiological characteristics and other properties of Borago officinalis L., Therefore, a factorial experiment were conducted in the form of randomized complete block design in 2018-2019. The experiment consisted of four sheep manure, cow manure, poultry manure and vermicomposting as the main factor and four levels of salicylic acid at concentrations of 0,10 -2 , 10 -4 10 -6 m as a sub-agent. Leaf areas, leaf number, chlorophyll a, chlorophyll b were measured as morphological indices and essential oil percentage, mean number of flowers per plant as physiological indices. The results of this study showed that application of applied fertilizers significantly increased vegetative and reproductive growth. It also has the greatest impact on fertilizers used in sheep and cattle. The impact of other used fertilizers was also significant. In acid-salt treatment, other levels used increased vegetative and reproductive properties. The highest effect was the level (10 -4) mol / liter.
