چکیده مقاله :
کودهای زیستی نقش بارزی در افزایش عملکرد کمی و کیفی گیاهان دارویی دارند. در این تحقیق اثرات کاربرد ورمی‌کمپوست و نیز کودهای پرمصرف نیتروژن و فسفر بر صفات مورفولوژیکی مانند ارتفاع گیاه و تعداد گره و نیز عملکرد کمی و کیفی اسانس گیاه نعناع فلفلی بررسی گردید. این پژوهش به صورت گلدانی در شرایط مزرعه‌ای بر اساس آزمایش فاکتوریل در قالب طرح کاملاً تصادفی با چهار تکرار در سال 1396 اجرا شد. سطوح تیماری ورمی‌کمپوست (مصرف و عدم مصرف طبق توصیه کارخانه سازنده)، کودهای نیتروژن و فسفر (0، 50، 100 و 150 کیلوگرم در هکتار) در مرحله تهیه بستر به خاک گلدان‌ها اضافه گردیدند. نتایج بدست آمده، نشان‌دهنده اثرگذاری معنی‌دار تیمارهای مورد استفاده بر صفات مورد ارزیابی بود. بیشترین اجزای موجود در اسانس (بیش از 70 درصد) شامل ترکیبات آلفاپینن، لیمونن، ایزومنتون، منتول، 1و8 سینئول، و منتون بود. در مقایسات میانگین‌ها، تیمار کاربرد ورمی‌کمپوست و کاربرد کود نیتروژن و فسفر (هرکدام یکصد کیلوگرم در هکتار)، بالاترین مقادیر صفات مورفولوژیکی از جمله ارتفاع گیاه و تعداد گره و همچنین بالاترین کمیت و کیفیت اسانس را ایجاد نمود. به نظر می‌رسد که کاربرد ورمی‌کمپوست موجب افزایش صفات مورفولوژیکی و به تبع آن میزان و اجزای سازنده اسانس گیاه شد.
Biological fertilizers play a significant role in increasing the quantitative and qualitative yield of medicinal plants. In this research, the effects of vermicompost as well as nitrogen and phosphorous fertilizers were investigated on morphological traits such as height of plant and number of nod and quantitative and qualitative functions of peppermint essential oil. A factorial study was conducted as a pot experiment under the field conditions in a completely randomized design with 4 replications in 2017. Vermicompost treatment levels (consumption and non-consumption according to the manufacturer's recommendation) and nitrogen fertilizers and phosphorus (0, 50, 100, and 150 kg ha-1) were added to the pot soils early at planting stage. The most essential components in the essential oil (more than 70%) were Alphapinene, Limonene, Izomenton, Menthol, 1, 8 Cineol, and Menton. Analysis of variations showed significant effectiveness of the treatments. Comparison of means suggested that the best treatments were application of vermicompost and nitrogen and phosphorus (100 kg. ha-1) that improved the morphological traits such as plant heights and number of nod and also the quality and quantity of essential oils. It seems that vermicompost increased morphological traits and consequently the amount and components of essential oil of the plant.
