The effect of organic fertilizer and mycorrhizal fungus on morphological characteristics, shoot biomass and mucilage of borage (Borago officinalis)

In order to study the effect of vermicompost, granular compost and mycorrhizal fungus on some quantitative and qualitative characteristics of borage, a factorial experiment based on randomized complete blocks design with three replications was conducted. Experimental treatments consisted of five levels of organic fertilization (zero, 5 and 10 tons per hectare vermicompost, 3 and 6 tons per hectare granular compost) and two levels of mycorrhizal fungi (no application and application of Gluomus mossae species). Results indicated that the highest yield of flowering shoot and LAI was obtained from the application of 10 tons per hectare vermicompost + mycorrhizal fungus. Also the highest baranch number per plant, height, 1000 seed weight and Musilage, belonged to the treatment of 10 tons per hectare vermicompost. Overal, results of this experiment showed that using of vermicompost and mycorrhiza can increase the LAI, height, 1000 seed weight, yield of flowering shoot, biological yield and mucilage percentage in borage. Therefore, the optimum organic and biologic inputs can be used to produce healthy borage plant.
