چکیده مقاله :
مشکلات فراوان حاصل از مصرف کودهای شیمیایی نیتروژنه در تولیدات گیاهی، صاحب نظران را بر آن داشته تا که از روش های جایگزین و پاک در راستای حرکت به سمت کشاورزی ارگانیک استفاده نمایند و در این میان مصرف کودهای آلی، ب ه ویژه ورمی کمپوست، از جمله اولویت ها محسوب می شود. به منظور بررسی اثر مصرف مقادیر مختلف کود نیتروژن و ورمی کمپوست بر عملکرد، اجزای عملکرد و میزان اسانس گیاه دارویی همیشه بهار آزمایشی در بهار سال 1392 در منطقه شهرری اجرا گردید. این آزمایش به صورت طرح کرت های خرد شده در قالب بلوک های کامل تصادفی با سه تکرار به اجرا درآمد. در این تحقیق مصرف کود شیمیایی نیتروژن در 4 سطح (0، 60، 120 و 180 کیلوگرم نیتروژن خالص در هکتار) به عنوان عامل اصلی و ورمی کمپوست در3 سطح (0، 10 و 20 تن در هکتار) به عنوان عامل فرعی در نظر گرفته شدند. نتایج به دست آمده نشان داد که گیاهان تیمار شده با نیتروژن در سطح 120 کیلوگرم در هکتار نسبت به سایر مقادیر مصرف، نتایج مطلوب تری را بر عملکرد، اجزای عملکرد و محتوی اسانس اندام های هوایی به همراه داشت. همچنین، اثر کاربرد ورمی کمپوست در سطوح 10 و 20 تن در هکتار بیشتر از تیمار عدم مصرف بود. نتایج مقایسه میانگین های اثر متقابل عوامل آزمایشی نشان داد که بالاترین عملکردهای دانه (1567 کیلوگرم در هکتار)، بیولوژیک (6664 کیلوگرم در هکتار) و اسانس (18.66 کیلوگرم درهکتار) با مصرف 120 کیلوگرم در هکتار نیتروژن و20 تن ورمی کمپوست در هکتار به دست آمدند.
Environmenal problems resulting from application of nitrogen fertilizers in the production plant materials led agricultural specialists to use clean and alternative methods to towards the organic farming and use of organic fertilizers. In this study, thus, the effect of nitrogen and vermicompost fertilizer rates on yield, yield components, essential oil content and some morphological traits of marigold was studied in a split plot experiment based on completely randomized blocks design with 3 replications in Shahr-e-Rey region during 2013 growing season. Nitrogen rates with 3 levels (0, 60, 120 and 180 kg.ha-1) were assigned to main plots and vermicompost with 3 levels (0, 10, and 20 t.ha-1) to the sub plots. Mean comparison of simple effects indicated that the plants treated with 120 kg.ha-1 nitrogen fertilizer and 20 t.ha-1 organic fertilizer vermicompost produced higher trait values under study than control (non application of vermincompost). Interaction effect of experimented factors was significant on all traits under evaluation. Thus, highest seed yield (1567 kg.ha-1), biological yield (6664 kg.ha-1) and essential oil yield (8.85 kg.ha-1) obtained by the application of 120 kg.ha-1 nitrogen fertilizer and 20 t.ha-1 varmicompost. Based on the results obtained it could be said that nitrogen and vermicompost may improve seed and biological yield and yield components of marigold.
