چکیده

اویارسلام ارغوانی، یکی از مشکل­سازترین علف‌های‌هرز مزارع پیاز است. با هدف بررسی روش­های مختلف مدیریتی این علف­هرز، آزمایشی در سال زراعی 97-1396، در مرکز تحقیقات و آموزش کشاورزی جنوب کرمان، به­صورت طرح بلوک‌های کامل تصادفی با سه تکرار اجرا شد. تیمارهای آزمایش شامل دوبار دیسک سنگین+ گلیفوسیت، شخم سنگین+ دیسک، متریبوزین، پندیمتالین (استامپ)، وجین دستی، آفتاب‌دهی خاک، آفتاب‌دهی خاک+ گلیفوسیت، عدم کنترل علف‌های‌هرز، پندیمتالین (پرول)، سه بار شخم و دوبار دیسک سنگین+ دوبارگلیفوسیت بودند. نتایج نشان داد که اثر تیمارهای مختلف بر وزن خشک اندام هوایی، زیرزمینی و تراکم اویارسلام ارغوانی، قطر گردن، تعداد برگ و عملکرد پیاز معنی دار بود به‌طوری­که تیمار تلفیق دوبار دیسک + دوبار گلیفوسیت،  تراکم و وزن خشک اندام زیرزمینی و هوایی اویارسلام ارغوانی را به‌ترتیب 86، 87 و 2/87 درصد کاهش داد و عملکرد پیاز را 83 درصد نسبت به تیمار شاهد افزایش داد. بنابراین، تلفیق دیسک و گلیفوسیت بر کنترل اویارسلام ارغوانی مطلوب و قابل توصیه است.

چکیده [English]

Purple nutsedge is one of the most problematic weeds of onion fields. To investigate the management practices of this weed, an experiment was conducted in the Agricultural and Natural Resources Center in Southern Kerman in 2017-2018 as a randomized complete block design with three replications. Treatments included twice disk + glyphosate, heavy plow + disk, metribiuzin, pendimethalin (Stomp), hand weeding, soil solarization, soil solarization + glyphosate, Control (no control), pendimethalin (Prowl), three times plowing, and twice disk + two times glyphosate. The results showed that the effect of different treatments was significant on shoot and underground dry weight and density, neck diameter, number of leaves and yield of onion. Twice disk + twice glyphosate decreased shoot and underground dry weight and density by 86, 87, and 87.2 %, respectively, and yield of onion increased 83 %. Therefore, combination of disk and glyphosate was desired in purple nutsedge control and this treatment is recommended.
