چکیده

اهداف: تحقیق حاضر با هدف بررسی اثر روش های غیرشیمیایی شامل مالچ زنده، مالچ کلش گندم و وجین دستی در ترکیب با علف‌کش تریفلورالین بر کنترل علف‌های‌هرز و عملکرد ریحان اجرا شد.
مواد و روش‌ها: آزمایش در مزرعه تحقیقاتی دانشگاه تبریز در سال 1401 بر پایه طرح بلوکهای کامل تصادفی با 12 تیمار و سه تکرار اجرا شد. تیمارهای مدیریت علف هرز شامل کاربرد علف‌کش تریفلورالین (ترفلان با فرمولاسیون 48 %EC) به مقدار 100‌ درصد توصیه شده (5/2 لیتر در هکتار)، کاربرد علف‌کش تریفورالین به مقدار 50‌ درصد توصیه شده (25/1 لیتر در هکتار)، کاربرد علف‌کش تریفورالین به مقدار 50 درصد توصیه شده در تلفیق با مالچ زنده گاودانه، مالچ کلش گندم و یک‌بار وجین دستی و استفاده از تیمارهای غیرشیمیایی ذکر شده به تنهایی (بدون کاربرد تریفلورالین) بودند.
یافته‌ها: بیشترین درصد کاهش زیست توده علف‌های هرز در تیمار تریفلورالین 50% + یک بار وجین دستی (85%) مشاهده شد که تفاوت معنی‌داری با تیمارهای یک بار وجین دستی (83%)، تریفلورالین 50% + مالچ کلش گندم (65%) و کاربرد تریفلورالین 100% (62%) نداشت. بیشترین وزن خشک ریحان (260 گرم در متر مربع) در تیمار تریفلورالین 50% + یک بار وجین دستی حاصل شد.
نتیجه‌گیری: استفاده از تیمارهای مدیریت علف‌هرز شامل یک بار وجین دستی و تریفلورالین 50% + مالچ کلش گندم می‌تواند در راستای کاهش مصرف علفکش‌ها و تولید پایدار ریحان به کشاورزان معرفی شود.

چکیده [English]

Background and Objective: This research was conducted in order to evaluate the effect of non-chemical methods including living mulch, straw mulch and hand weeding in integration with trifluralin on weed control and basil (Ocimum bacilicum L.) yield.
Material and methods: The experiment was conducted in Research Field of University of Tabriz in 2022 based on randomized complete block design with 12 treatments and three replications. Weed management treatments included weed-free treatment in entire growth season, weed-infested treatment in entire growth season, using the trifluralin herbicide (Treflan EC 48%) at 100% of the recommended dose (2.5 L ha-1), trifluralin herbicide at 50% of the recommended dose (1.25 L ha-1), trifluralin herbicide at 50% of the recommended dose in integration with bitter vetch living mulch, wheat straw mulch and one time hand weeding and using mentioned non-chemical treatments alone (without application of trifluralin).
Results: The highest weed biomass reduction percentage was observed in trifluralin 50% + one time hand weeding (85%) that was not significantly different with those in one time hand weeding (83%), trifluralin 50% + wheat straw mulch (65%) and trifluralin 100%. The highest basil dry weight (260 g m-2) was obtained in trifluralin 50% + one time hand weeding.
Conclusion: Using weed management treatments including one time hand weeding and trifluralin 50% + wheat straw mulch could be introduced to the growers in line with reduction of herbicide application and sustainable production of basil
