Abstract
In order to investigate the effect of biofertilizers on improving the morphological and biochemical traits of Iranian borage in 2021 in a farm in Kalaleh city located in Golestan province was carried out factorially in a randomized complete block design with 3 replications. In this study, the first factor included seaweed extract at four different levels of 0, 0.5, 1 and 2 ml / l and the second factor included inoculation of seeds before planting with two species of mycorrhizal fungi (Glomus mosseaeae and Glomus interradices), two Bacterial type (Azetobacter chroococcum and Azospirillium brasilence) and control (no seed inoculation). According to the results, the experimental treatments had a significant effect on traits such as number and dry flower yield, number of lateral branches and shoot dry weight of Iranian borage. The highest yield and number of flowers were related to 0.5 ml / l algae extract and Azetobacter and the lowest yield and number of flowers were related to control treatment (without inoculation and foliar application). Also, the effect of seaweed extract, mycorrhizal fungi, growth-promoting bacteria and their interaction on traits such as flavonoids, phenols, anthocyanins and soluble sugars was significant. The simple effects of seaweed extract, mycorrhizal fungi and growth-promoting bacteria on plant height and shoot fresh weight were significant. The amount of potassium, phosphorus and nitrogen also increased significantly under the influence of treatments. The highest amount of nitrogen in the treatment of 0.5 ml / l of algae extract and Azospirillium bacteria, the highest amount of phosphorus in the treatment of 1 ml / l of the algae and fungus Glomus interradices and the highest amount of potassium in the treatment of 2 ml / l of the algae and Azetobact bacterium. The lowest levels of nitrogen, phosphorus and potassium were related to the control treatment.
