چکیده

به‌منظور بررسی کاشت گندم در بقایای گیاهی ذرت (بی‏خاک‏ورزی) و تأثیر آن بر میزان بذر و کود نیتروژن مصرفی در راستای کشاورزی پایدار، آزمایشی به‌صورت اسپلیت فاکتوریل در قالب طرح پایه بلوک‏های کامل تصادفی با چهار تکرار و با سه عامل رقم، در دو سطح (بهرنگ (V1) و چمران (V2)، تراکم بذر در پنج سطح (50 (D1)، 100 (D2)، 150 (D3)، 200 (D4) و 250 (D5) کیلوگرم در هکتار) و کود نیتروژن از منبع اوره در 6 سطح (0 (N1)، 50 (N2)، 100 (N3)، 150 (N4)، 200 (N5) و 250 (N6) کیلوگرم در هکتار) در پاییز سال 1391 – 1390 در مزرعۀ کشاورزی واقع در جنوب دزفول به اجرا در آمد. نتایج تجزیه واریانس صفات مورد مطالعه نشان داد که اثرات رقم، کود نیتروژن و بذر مصرفی بر روی عملکرد و اجزای عملکرد دانه در سطح احتمال یک درصد معنی‏دار بود. مصرف بذر بیش از 100 کیلوگرم در هکتار عملکرد دانه را کاهش و افزایش مصرف نیتروژن تا سطح 150 کیلوگرم در هکتار موجب افزایش معنی‏دار در عملکرد دانه گردید. رقم چمران با میانگین عملکرد دانه70/413 کیلوگرم در هکتار نسبت به رقم بهرنگ برتری داشت و همچنین بهترین عملکرد دانه در تراکم 100 کیلوگرم بذر در هکتار با میانگین 5 تن در هکتار به‌دست آمد.
