چکیده

به‎منظور بررسی تأثیر الگوی کاشت و نیتروژن مصرفی بر کمیت و کیفیت علوفه در کشت مخلوط جو و باقلا، آزمایشی در سال زراعی 92-1391 در مزرعۀ دانشکدۀ کشاورزی و منابع طبیعی دانشگاه گنبدکاووس به‌صورت فاکتوریل در قالب طرح بلوک‏های کامل تصادفی با سه تکرار انجام شد. عامل الگوی کاشت در پنج سطح شامل کشت خالص جو، کشت مخلوط 25، 50 و 75 درصد باقلا به‌جای جو و کشت خالص باقلا بود. عامل کود نیتروژن در چهار سطح شامل 0، 25، 50 و 75 کیلوگرم نیتروژن خالص در هکتار بود. نتایج نشان داد که تأثیر الگوی کاشت بر عملکرد علوفه، ارتفاع بوته، درصد مادۀ خشک قابل‌هضم، پروتئین خام و فیبر غیرقابل‌حل در شوینده‌های اسیدی معنی‌دار شد. کود نیتروژن بر عملکرد علوفه، ارتفاع بوته، درصد پروتئین و درصد مادۀ خشک قابل‌هضم تأثیر افزایشی داشت. کشت خالص جو با 38/13 تن بیشترین و کشت خالص باقلا با 4/7 تن کمترین عملکرد علوفه را در هکتار تولید کردند. با افزایش نسبت باقلا در تیمارهای کشت مخلوط، عملکرد کل نسبت به کشت خالص جو کاهش یافت. بیشترین و کمترین پروتئین خام با 37/25 و 81/8 درصد و مادۀ خشک قابل‌هضم با 96/69 و 96/58 درصد به ترتیب از کشت خالص باقلا و جو به دست آمد. اگرچه عملکرد علوفه در کشت خالص جو زیاد بود، اما کیفیت پایینی داشت.

چکیده [English]

In order to study the effect of planting pattern and nitrogen application on barley and faba bean yield and quality of forage in intercropping, an experiment was conducted on farm of agricultural and natural resources faculty of Gonbad Kavous University as factorial based on RCBD with three replications in 2012-2013. Planting pattern consisted of five levels, i.e. sole barley, intercropping of barley with faba bean at 75:25, 50:50, 25:75 rations and sole faba bean and nitrogen fertilizer factor was comprised of four levels of 0, 25, 50 and 75 Kg N ha-1. The results showed that effect of planting pattern on forage yield, height, percentage of dry matter digestibility, crude protein and acid detergent fiber at 1% probability level were significant. Nitrogen fertilizer had additive effect on forage yield, height, percentage of dry matter digestibility and crude protein. Sole barley produced the highest yield with13.38 ton ha-1 and sole faba bean produced the lowest forage yield with 7.4 ton ha-1. With increasing of faba bean in intercropping treatments, total yield decreased compared to sole barley. The highest and lowest crude protein percentage with 25.37 and 8.81 and dry matter digestibility with 69.96 and 58.96 percent was obtained from sole faba bean and sole barley, respectively. Although forage yield in sole crop of barley was high but its quality was low.
