Abstract Background & Objective: Soil low fertility resulted from continuous chemical fertilizer application turned to be a challenge to sustainable agricultural production. Complementary application of chemical and organic fertilizers is a fertilizer management strategy and a practical solution for reducing the dependency to chemical fertilizer. Materials & Methods: Since little reports about eryngo reaction toward fertilization exist, a field experiment based on split-plot design with 3 replications with two treatments, fertilization as the main plot with 8 treatments and harvesting stage as sub-plot with three developmental phases was conducted in 2016 in Ferdowsi University of Mashhad. Results: The results revealed that appropriate application of organic with inorganic fertilizers increased eryngo’s productivity and its phytochemical constituent. NPK fertilizer (200 Kg.ha-1) + CM (20 t.ha-1) in leaf number per plant (28), herb yield (498.77 Kg.ha-1), flavonoid (41.10 mg QE .g-1 dry sample), antioxidant (85.64%), essential oil percentage (0.17%W/W) and yield (0.85 Kg.ha-1) at last harvest resulted to the highest amounts. The minimum amounts were produced at control and first harvest. Mycorrhizae symbiosis and Manure treatments in the first harvest did not represent any difference with control but over time, the difference grew up into a considerable level. Result showed that the effects of conventional 100% NPK and 50% CM + 50% NPK fertilizers were almost similar. Application of these fertilizers increased yield and phytochemical traits. Conclusion: In view of the positive reaction of eryngo toward fertilization specially to integrated treatments, we can take advantage of these fertilizations to produce safe and healthy crop.
