چکیده

اهداف: رشد روز افزون مصرف و ارزش بالای اقتصادی گیاه دارویی بالنگوی شهری تحقیق پیرامون کشت و کار این گیاه را ضروری میباشد. بالنگوی شهری بدلیل استفاده بهتر از بارندگی، نیاز آبی و کودی کمتر میتواند بعنوان یک گونه جدید از گیاهان دارویی در شرایط دیم باشد.
مواد و روشها: آزمایش بصورت کرتهای خرد شده نواری بر پایه طرح بلوکهای کامل تصادفی در سه تکرار در منطقه خرم آباد در سال زراعی 97-1396 اجرا شد. تیمارهای آزمایش شامل دو روش خاکورزی (مرسوم و روش بی خاکورزی) و پنج توده بالنگوی شهری شامل (تکاب، کلیبر، کردستان (سنندج)، نظرکهریزی و جلفا) در کرتهای فرعی قرار گرفتند.
یافته‌ها صفات ارتفاع بوته و تعداد دانه در فندقه تحت تأثیر روش‌های خاکورزی قرار گرفتند. عملکرد زیستی در روش بی خاکورزی و توده تکاب نسبت به خاکورزی رایج و دیگر توده‌های مورد بررسی افزایش 14/5 درصدی نشان داد. توده کلیبر دارای بیشترین ارتفاع بوته، تعداد شاخه‌های فرعی و تعداد فندقه در بوته بود. خاکورزی مرسوم بیشترین ارتفاع بوته (09/64 سانتیمتر) و تعداد فندقه در بوته (07/3 عدد) بدست آمد. بالاترین عملکردهای دانه (41/206 گرم در متر مربع) مربوط به روش خاکورزی رایج در توده کلیبر بود که اختلاف معنی‌داری با روش بدون خاکورزی در این توده مشاهده شد. وکمترین عملکرددانه نیز در روش خاکورزی رایج و توده جلفا (24/73 گرم در متر مربع) بدست آمد.
نتیجه‌گیری: تیمار بدون خاکورزی جهت کاهش هزینه‌های تولید، نیروی کار و مصرف انرژی، بهینه از زمان و کاهش تردد ماشینهای کشاورزی در مزرعه قابلیت جایگزینی با سیستم خاکورزی مرسوم را دارد.

چکیده [English]

Background & Objective: Increasing consumption and high economic value of urban medicinal plant Balangu Research on cultivation of this plant is essential. Due to better use of rainfall, water requirement and less fertilizer can be used as a new species of medicinal plants in rain fed conditions.
Methods & Materials: The experiment was conducted in the form of strip split plots based on a randomized complete block design in three replications in Khorramabad region in the 2016/17. Experimental treatments including two tillage methods (conventional tillage and non-tillage) and five Balangu masses including (Takab, Kalibar, Kurdistan (Sanandaj), Nazarkahrizi and Jolfa) were placed in sub-plots.
Results: Plant height and number of seeds per hazelnut were affected by tillage methods. Biological yield in tillage method and Takab mass showed an increase compared to conventional tillage and other studied masses. Kalibar mass had the highest plant height, number of sub-branches and number of hazelnuts per plant. In soilless cultivation method, the highest plant height and number of hazelnuts per plant were obtained. The highest grain yields were related to the common tillage method in Kalibar massif, which showed a significant difference with the no-tillage method in this massif. Also, the lowest grain yield was obtained in the conventional tillage method and Julfa mass.
Conclusion: Non-tillage treatment can be replaced with conventional tillage system to reduce production costs, labor and energy consumption and optimal use of time and also reduce the movement of agricultural machinery on the farm.
