| چکیده | ||
| به منظور بررسی تأثیر دوزهای کاهش یافته علفکش اگزادیارژیل بهصورت پسرویشی در کنترل علفهایهرز مزارع سیبزمینی، آزمایشی مزرعهای در سال 1392 در ایستگاه تحقیقات کشاورزی و منابع طبیعی آلاروق اردبیل انجام شد. آزمایش به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی با سه تکرار و روی رقم آگریا انجام شد. فاکتور اول هفت دز کاهش یافته علفکش اگزادیارژیل شامل صفر، 05/0 ، 1/0 ، 2/0 ، 4/0، 6/0 و 8/0 لیتر ماده مؤثره در هکتار و فاکتور دوم زمان سمپاشی در سه مرحله سبز شدن سیبزمینی، استولونزایی و حجیمشدن غده بود. نتایج نشان داد که کاربرد دوز 8/0 لیتر ماده مؤثره در هکتار به ترتیب باعث کاهش تراکم و زیست توده علفهایهرز به میزان 40/48 و 10/66 درصد شد که با دز 6/0 لیتر ماده مؤثره در هکتار تفاوت معنیداری نداشت. در بین زمانهای مختلف مصرف علفکش اگزادیارژیل، بالاترین درصد کاهش تراکم و زیست توده علفهایهرز در مرحلهی سبز شدن سیبزمینی بود که بیانگر مؤثر بودن علفکش اگزادیارژیل در مرحله سبز شدن سیبزمینی میباشد. از سویی دیگر، کاربرد اگزادیارژیل به میزان 8/0 لیتر ماده مؤثره در هکتار و در مرحله سبزشدن سیبزمینی، بالاترین متوسط وزن غده در بوته و عملکرد کل غده در هکتار را ایجاد کرد اما بر تعداد غده در بوته تأثیر معنیداری ایجاد نکرد. | ||

| چکیده [English] | ||
| In order to study the effect of reduced doses of oxadiargyl, on weeds control in potato, a field experiment was conducted at Alaroog Research Station in Ardabil during 2013. Experiment arrangement was factorial based on randomized complete blocks design with three replications. First factor included seven reduced dosages of oxadiargyl (0, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8 L a.i/ha) and second factor included oxadiargyl application timing (potato emergence, stoloning and tuber bulking). The results showed that application of 0.8 L a.i/ha of oxadiargyl reduced weed density and biomass to 48.40 and 66.16 percent, respectively which was not significantly different from applying 0.6 L a.i/ha. Maximum reduction percentage of weed density and biomass on the different potato growth stages was at potato emergence stage, which provided the best effectiveness of the oxadiargyl. On the other hand, application of 0.8 L a.i/ha oxadiargyl at potato emergence stage caused the highest mean of tubers weight per plant and total tuber yield, but was not significant on the tuber number per plant. | ||
