به منظور بررسي اثر چاي كمپوست، ورمي كمپوست و همزيستي ميكوريزايي بر برخي از خصوصيات مورفولوژيكي نعناي صحرايي آزمايشي به صورت فاكتوريل در قالب طرح كاملي تصادفي با 4 تكرار در سال 1393 در ساري اجرا شد. فاكتورهاي آزمايش شامل ميكوريزا گونه Glomus roseae(صفر و 10 درصد حجم گلدان)، ورمي كمپوست (صفر و 10 درصد حجم گلدان) و چاي كمپوست (صفر و 1/5 ليتر) بود. صفاتي از قبيل شاخص سطح برگ و وزن خشك بوته مورد بررسي قرار گرفت. نتايج بدست آمده نشان داد تيمارهاي كود آلي و ميكوريزا تأثير معني دار بر وزن خشك و تر و داشتند و كليه صفات مورد بررسي را در مقايسه با شاهد افزايش دادند. به طوري كه وزن تر بوته، عرض برگ از تيمار همزيستي ميكوريزايي + جاي كمپوست + ورمي كمپوست به دست آمد. اثرات متقابل سه گانه نشان داد كاربرد چاي كمپوست به كاربرد ورمي كمپوست × عدم كاربرد ميكوريزا شاخص سطح برگ را نسبت به شاهد افزايش داد. كاربرد ورمي كمپوست، چاي كمپوست و همزيستي ميكوريزايي از طريق در دسترس قرار دادن عناصر غذايي باعث افزايش رشد گياه، افزايش اجزاي عملكرد و بهبود صفات كمي گياه نعناي صحرايي گرديد.

The genus Mentha includes 25–30 species that grow under
cultivation from tropical to temperate climate of America, Europe,
China, Brazil, India, Australia, and South Africa. Cultivation of
medicinal plants with organic fertilizers and biological,
pharmaceutical and negative effects on the quality of their
performance reduces, (Griffe et al., 2003). Sustainable agriculture
based on the use of bio-fertilizers for the purpose of eliminating or
significantly reducing the use of chemical inputs, the optimal
solution for overcoming these problems is comes to. Of biofertilizers
contain preservatives densely populated beneficial soil organisms or
for one or more metabolic products are available to improve soil
fertility and appropriate supply of nutrients needed by plants in a
sustainable agricultural system used (Saleh Rastin, 2001). The main
aims of this study were the effect of Mycorrhizal symbiosis, use of
Vermi compost and Compost tea on growth, yield and quality
Melissa officinalis. Field experiment was carried out at Sari (53° 63´
E and 36° 82´ N and a height 43.3 meter from sea level), Mazadaran
province, Iran in 2014-2015. The soil chemical characteristics were
included 7.30 pH, 2.1% organic carbon, 1.15% total nitrogen, 5.5
ppm phosphorous and 280 ppm potassium. The trial was set up as a
factorial experiment in a randomized complete block design with 4
replicates. The experimental factors were included biofertilizer with
three levels (inoculation with Mycorrhiza, inoculation with vermi
compost and compost tea. For mycorrhiza treatments, Glomus
mosseae strain was applied at 10% of each pot time of sowing.
vermi compost 10% of each pot with animal origin was applied
Compost tea with a volume of 1liters at the 4-5 leaf stage were
sprayed on plant leaves. Data analysis All measurements were
analyzed of variance with the using of SAS software. Means were
evaluated by LSD test. The results showed that The combination of
low input and ecological systems and Mycorrhizal symbiosis
inoculation and organic fertilizers application such as Compost and
vermi compost can substitute chemical fertilizers.The results of the
study showed that organic fertilizers and mycorrhizal had significant
impact on all measured characteristics and increased dry and fresh
weight characteristics when compared with those of the control
group So that the fresh weight, Leaf width were obtained from the
mycorrhizal, compost tea and vermicomposting treatment. The
application of vermicomposting, compost tea and mycorrhizal
symbiosis through making the nutrients available increased plant
growth, yield components and improve Mentha spicata quantitative
characteristics.
