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
