Abstract
Introduction: Increasing application of chemical fertilizers has led to irreparable environmental and sanitary damage. Due to their residual in nature, chemical fertilizers also cause to soil and water pollution and various diseases such as: cancer in humans. These disadvantages of chemical fertilizers and high production cost led to serious attention to bio-fertilizers production. The present study aimed to investigate the effect of organic fertilizers (vermicompost and vermiwash) and mycorrhizae symbiosis on yield and yield components of Menthaspicata L.
Materials and Methods: The experiment was conducted as factorial based on randomized complete design with four replications in Sari city during 2014-2015. The experimental factors included mycorrhizae (Glomus moseae specie) at two levels (0 and 200 spores per pot), vermicompost at two levels (0 and 200 g per pot) and tea compost at two levels (0 and 1.5 liters per specified pots). Characteristics such as: leaf area, number of branches, dry weight yield, root of diameter, length and dry weight, plant height, percentage and essential oil yield were evaluated.
Results: Results showed that the application of organic fertilizers and mycorrhizael symbiosis had a significant impact on leaf number, root dry weight and increased all characteristics compared to the control. Based on the results, the highest value of height (33.27 cm) was observed in the application of tea compost + no Vermicompost + no mycorrhizae treatment, maximum leaf number (26.95 numbers) was gained in mycorrhizae symbiosis treatment along with the use of application of tea compost + vermicompost, highest percentage of essential oil (0.86%) was observed in the application of vermicompost + mycorrhizael symbiosis + no tea compost treatment. The highest essential oil yield (1.80 g/pot) and the highest leaf area (123.49 cm) were observed in application of tea compost + vermicompost + no mycorrhizae treatment.
Conclusion: In generally, the organic and biological fertilizers have a positive impact on the yield and yield components of Menthaspicata L. The application of vermicompost, tea compost and mycorrhizael symbiosis through availability of nutrients led to qualitative and quantitative qualities of Menthaspicata L.
