The seeds of the medicinal plant dragon's head are an excellent source of fiber, oil, and protein, and are used to treat a variety of conditions, including certain nervous disorders, liver diseases, and kidney diseases. This study aimed to determine the effects of foliar application of various nano-chelate and chemical boron fertilizers on morphological indices of the dragon's head (Lallemantia iberica). This study employed a completely randomized design with nano-chelate (500, 1000, and 1500 mg/l) and boric acid (1000, 2000, and 3000 mg/l) treatments, in addition to a control group. The results demonstrated that the investigated treatments had a significant effect on the majority of dragon's head indices. The highest inflorescence length (43.66 cm) and number of cycles in the main branch (28.56) were observed in the boric acid treatment with 3000 mg/l of boric acid. The highest number of lateral branche, flower cycle per plant, and seed weight per plant, 1000-seed weight, and seed yields were obtained at 3000 mg/l of boric acid and 1500 mg/l of nano-chelated treatments, respectively. The highest number of seed per plant, plant dry weight, and biological yield were obtained in the treatments of 2000 and 3000 mg/l of boric acid and 1500 mg/l of nano-chelated boron fertilizers, respectively. Application of boron fertilizers significantly increased the nitrogen, phosphorus, potassium, and boron concentrations in the treated plants. In general, foliar application of boron micronutrient increased the yield and improved the indices of dragon’s head. Consequently, the application of nano-fertilizers yielded promising results due to their higher absorption efficiencies at lower concentrations than conventional fertilizers.

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.
