Because it generates the zero-calorie sweeteners steviol glycosides, Stevia rebaudiana is a valuable medicinal plant that offers herbal care for diabetic patients. The effects of applying vermicompost water extract and inoculating S. rebaudiana with Serendipita indica on the growth of the plant were investigated in this study using an in vitro experimental design that was completely randomized. The application of vermicompost water extract and inoculation with S. indica had a significant impact on the majority of the plant's growth parameters, as indicated by the results. S. rebaudiana inoculated with S. indica exhibited the greatest root length, chlorophyll content, and dry weight of aerial parts. Additionally, when inoculated with vermicompost water extract, S. rebaudiana demonstrated the maximum chlorophyll content and the ratio of fresh weight of roots to fresh weight of aerial parts. Large-scale application of the findings from this study is possible in the tissue culture of medicinal plants. Conversely, in sustainable agriculture, the utilization of water extract vermicompost and S. indica fungus may lead to enhanced vegetative products and, consequently, secondary metabolites in medicinal plants.

In order to examine the impact of biofertilizer on the essential oil and seed yield of Moldavian balm, a factorial experiment with a randomized complete block design and three replications were designed at the Khoy Agricultural Research Center in the West Azerbaijan Province. Five fertilization levels were applied: 100% urea (70 kg N ha−1), 75% urea (52.5 kg N ha−1) + 25% azocompost (3.85 ton ha-1), 50% urea (35 kg N ha−1) + 50% azocompost (7.77 ton ha-1), 25% urea (17.5 kg N ha−1) + 75% azocompost (11.55 ton ha-1), and 100% azocompost (1555 ton ha-1) on two Moldavian balm landrace (Urmia and the modern cultivar SZK-1). The results of this study indicated that a 100% urea fertilizer regime produced the highest dry herbage yield. The highest seed yield was achieved with a 100% urea fertilizer application of approximately 1,122 kg ha-1. Inoculating seeds with Azotobacter and Azospirillum bacteria resulted in the highest harvest index, with a value of 22.4 percent. The Urmia landrace genotype had the highest yield of essential oil (20.5 kg ha-1). Based on the findings, the 50% urea + 50% azocompost fertilizer treatment had the greatest effect on the majority of the investigated characteristics.
