چکیده

به منظور بررسی اثر کشت مخلوط ماشک و گشنیز در شرایط استفاده از کودهای زیستی و ورمی کمپوست بر زیست توده علف های هرز، آزمایشی به صورت کرت خرد شده در قالب طرح بلوک های کامل تصادفی با 3 تکرار در مزرعه تحقیقاتی پردیس کشاورزی و منابع طبیعی دانشگاه تهران (کرج) در سال زراعی1390-1389  انجام شد.  عامل اصلی با چهار سطح کودی شاهد (عدم مصرف کود)، ورمی کمپوست، کود زیستی، کودزیستی+50% ورمی کمپوست و عامل فرعی در هفت سطح کشت مخلوط افزایشی شامل: 1. کشت خالص ماشک بدون وجین علف هرز (Vw 2. کشت خالص ماشک با وجین علف هرز (V0  3. کشت خالص گشنیز بدون وجین علف هرز (Cw 4. کشت خالص گشنیز با وجین علف هرز (C0)، 5. ماشک 100%+گشنیز 50% (VC50) ،  6. ماشک 100% + گشنیز 75% (VC75)،  7. ماشک 100% + گشنیز 100%  VC100))، مورد بررسی قرار گرفتند.  در این آزمایش صفت زیست توده علف هرز مطالعه قرار گرفت.  نتایج آزمایش نشان داد تیمار ورمی کمپوست در تمام سطوح کشت مخلوط بیشرین اثر را بر کاهش زیست توده علف هرز داشت.  همچنین سطوح کشت مخلوط افزایشی ماشک +75% گشنیز و ماشک + 100% گشنیز اثر بسزایی در کاهش زیست توده علف هرز داشت. بر اساس نتایج این تحقیق به طور کلی به منظور کاهش مصرف علف کش ها شیمیایی به لحاظ زیست محیطی و افزایش سطح سلامتی، استفاده از الگوی کشت مخلوط و کودهای با منشا طبیعی قابل توصیه است.

چکیده [English]

To investigate the effect of biological fertilizers and vermicompost, on vetch and coriander in different intercropping mixtures (medicinal forage), an experiment was conducted in split plot based on RCBD design with 3 replications. The experiment was conducted in Research Farm of College of Agriculture, University of Tehran in Karaj, Iran during growing season of 1389-1390   The main factor comprised of 4 levels of fertilizer application viz. control (no fertilizer application), vermicompost, biological fertilizer and biological fertilizer + 50% vermicompost.  The sub plots were allocated to 7 levels of different mixtures of intercropping of vetch and coriander including: sole cropping of vetch (weed infested) (Vw), sole cropping of vetch (weed free) (V0), sole cropping of coriander (weed infested) (Cw), sole cropping of coriander (weed free) (C0), intercropping of vetch + 50% coriander (VC50), intercropping of vetch + 75% coriander (VC75), and intercropping of vetch + 100% coriander (VC100).  The measured parameters  was weed biomass.  The results indicated that vemicompost across all levels of intercropping had significant effect on decrease weed biomass.  Also the lowest weed biomass was achieved in (VC75) and (VC100) intercroppings.  According to the results of this experiment, to decrease the consumption in herbicides and increase the level of health application of intercropping and natural fertilizers could be recommended.
