ملخص المقالة :
به‌منظور مطالعه تأثیر کشت مخلوط درهم بر عملکرد و اجزای عملکرد جو و ماشک گل خوشه‌ای آزمایشی در دو سال زراعی (1394-1393) در ایستگاه تحقیقات کشاورزی و منابع طبیعی میاندوآب بر پایه طرح بلوک های کامل تصادفی در چهار تکرار اجرا شد. تیمارهای آزمایشی شامل نه تیمار کشت مخلوط با تراکم‌های250 بوته در متر مربع ماشک+ 300 بوته جو، 250 بوته ماشک+ 500 بوته جو، 250 بوته ماشک + 700 بوته جو، 450 بوته ماشک+ 300 بوته جو، 450 بوته ماشک+ 500 بوته جو، 450 بوته ماشک+ 700 بوته جو، 650 بوته ماشک + 300 بوته جو، 650 بوته ماشک+ 500 بوته جو و 650 بوته ماشک+ 700 بوته جو و دو تیمار کشت خالص ماشک (250 دانه در متر مربع) و جو (350 دانه در متر مربع) بودند. نتایج تجزیه واریانس مرکب نشان داد که بین تیمارها از لحاظ کلیه صفات در هر دو محصول اختلاف معنی‌دار وجود داشت. کشت خالص جو بالاترین سنبله در متر مربع (97.88)، وزن هزار دانه (47.28 گرم) وعملکرد بیولوژیک (13.36 تن در هکتار) و عملکرد دانه (4.36 تن در هکتار) را به خود اختصاص داد. هم چنین، بالاترین تعداد ساقه (379.25) و عملکرد بیولوژیک (7.63 تن در هکتار) و عملکرد دانه (1.94 تن در هکتار) ماشک در کشت خالص مشاهده شد. بالاترین نسبت برابری زمین هم بر اساس عملکرد دانه (1.20) و هم بر اساس عملکرد بیولوژیک (1.48) در تیمارهای تراکم 500 بوته جو + تراکم 250 بوته ماشک در متر مربع دیده شد، که نشان دهنده مزیت کشت مخلوط در مقایسه با کشت خالص این دو محصول بود.
