چکیده

به­منظور تعیین مناسب‌ترین روش کنترل علف‌های­هرز در دو سیستم کشت رایج و کشت با فواصل ردیف خیلی باریک، آزمایشی به­صورت فاکتوریل در قالب طرح پایه بلوک‌های کامل تصادفی در سه تکرار در شهرستان سبزوار در سال زراعی 95-1394 به­اجرا درآمد. فاکتورهای مورد مطالعه شامل سیستم کاشت در دو سطح کشت به­صورت رایج (فاصله ردیف 70 سانتی‌متر) و فواصل ردیف خیلی باریک (20 سانتی‌متر) و روش کنترل علف‌های هرز در شش سطح بدون کنترل علف‌های هرز (به­عنوان شاهد)، کاربرد علف‌کش در غلظت توصیه‌شده (تری­فلورالین (ترفلان 48% EC) 1160 گرم ماده موثره در هکتار)، کاربرد 50 درصد غلظت توصیه‌شده علف‌کش+ یک‌بار وجین در 45 روز بعد از سبز شدن، کاربرد 50 درصد غلظت توصیه‌شده علف‌کش+دو بار وجین در 30 و 60 روز بعد از سبز شدن، سه بار وجین در 30، 45 و 60 روز بعد از سبز شدن و کنترل کامل علف‌های هرز بودند. نتایج آزمایش نشان داد که در کشت با فواصل ردیف خیلی باریک تراکم علف­هرز (71/33 درصد)، تعداد شاخه جانبی (37/14 درصد)، تعداد غوزه در بوته (88/16 درصد) و وزن غوزه (30/12 درصد) کمتر و عملکرد وش (85/39 درصد) و عملکرد الیاف (71/23 درصد) بیشتر از کشت رایج بود. در کشت رایج در صورت کاهش 50 درصدی غلظت علف‌کش نیاز به دو بار وجین در مراحل 30 و 60 روز بعد از سبز شدن و در کشت با فواصل ردیف خیلی باریک در صورت کاهش 50 درصدی غلظت توصیه‌شـده یک‌ بار وجین در مرحله 45 روز بعد از سبز شدن جهت حصـول عملکرد وش منـاسب توصیه می­شود. در مجموع نتایج آزمایش نشان داد که می­توان در سیستم کاشت با فواصل خیلی باریک با کاهش 50% مصرف علف‌کش تری فلورالین و کاهش دفعات کنترل علف‌های هرز (یک­بار وجین در 45 روز بعد از سبز شدن)، عملکرد وش مشابهی با سایر روش‌های کنترل به­دست آورد.

چکیده [English]

To determine the most appropriate method of weed management in conventional row and ultra narrow row spacings of cotton, a factorial experiment was based on a randomized complete block design with three replications was conducted in Sabzevar in 2015-2016. Factors under study were plant spacings in two levels, conventional (70 cm row spacing) and ultra-narrow row (20 cm row spacing) and weed management in six levels: without controlling of weeds (control), application of herbicide at recommended dose of Ethalfluralin (Treflan 48% EC) at 1160 g/ai ha), application of herbicide at 50% recommended dose + hand weeding at 45 days after emergence (DAE), application of herbicide at 50% recommended dose + two times hand weeding at 30 and 60 DAE, three times hand weeding at 30, 45 and 60 DAE, and full weed free condition. The results showed that traits like weed density, by 33.71 percent, lateral branches by 14.77 percent, number of bolls per plant by 16.88 percent, and boll weight by 12.30 percent were lower in narrow row spacing, while seed cotton yield by 39.85 percent and fiber yield by 23.71 percent higher, as compared to, conventional row spacing. In the conventional cultivation system, if 50% of the herbicide dose is reduced, it needs two hands weeding at 30 and 60 DAE; while in ultra-narrow row spacing condition, with a 50% reduction in the recommended herbicide dose, one hand weeding at 45 DAE is needed to achieve suitable seed cotton yield. As a whole, the results showed that, under ultra-narrow row spacing, with a 50% reduction in herbicide dose and reduced weed control times (only one hand weeding at 45 DAE) it can be obtained seed cotton yield similar to other control treatments.
