Abstract: (3 Views)
Background and Objective: Ajwain, a medicinal plant, is used widely in traditional and modern medicine, as well as in the food, livestock and poultry industries. This study was conducted to investigate the role of organic and biological fertilizers on the quantitative and qualitative performance of Ajwain.
Methods: A field experiment was conducted in a split factorial arrangement based on a randomized complete block design with three replications to investigate the effects of biofertilizers on the quantitative and qualitative traits of Ajwain. Vermicompost was applied at three levels: 0 (control), 5, and 10 t/ha as the main factor. Mycorrhizal fungi were applied at three levels: no application (control), application of Rhizophagus irregularis and Funneliformis mosseae, and the presence or absence of the growth-promoting bacterium Azotobacter chroococcum.
Conclusion: The results highlight the importance of using organic and biological fertilizers to enhance the quantitative yield of Ajwain. However, it seems that the quality control of EO is not affected by the treatments used and may depend on genetic factors and other agronomic treatments, including stresses.

Mycorrhizal fungi were applied at three levels: no application (control), application of Rhizophagus irregularis and Funneliformis mosseae, and the presence or absence of the growth-promoting bacterium Azotobacter chroococcum.
Results: According to the results, the symbiotic interaction between mycorrhizal fungi (Rhizophagus irregularis and Funneliformis mosseae), Azotobacter chroococcum, and vermicompost significantly improved growth indices, yield of plant organs, and essential oil (EO) yield, but did not significantly affect the EO percentage and phytochemical compounds.
Funneliformis mosseae had the greatest impact on aerial parts, including the number and diameter of lateral stems, stem diameter and seed yield while Rhizophagus irregularis played a more effective role in increasing root length, weight, and development of roots and seed yield. However, the use of organic and biological fertilizers did not significantly affect the major compounds of EO. The highest contents of p-cymene (15.05%) and γ-terpinene (48.40%) were obtained using vermicompost (5 and 10 t/ha, respectively), and thymol (35.74%) with Rhizophagus irregularis.Conclusion: The results highlight the importance of using organic and biological fertilizers to enhance the quantitative yield of Ajwain. However, it seems that the quality control of EO is not affected by the treatments used and may depend on genetic factors and other agronomic treatments, including stresses.
