In order to evaluate the effect of different planting seedbeds (stale and false) and application of Oxyfluorfen herbicide on yield, yield components and control of garlic weeds, a split-plot experiment was conducted based on a randomized complete block design (RCBD) with three replications in the cropping year 2020-2021 at Agricultural Sciences and Natural Resources University of Khuzestan. The main plot consisted of different planting seedbeds: Conventional seedbed (without irrigation using plow and disc); stale seedbed (using Paraquat herbicide); stale seedbed (using Glyphosate herbicide); false seedbed (using flame application) and false seedbed (with manual cultivation). Different dosages of Oxyfluorfen herbicide (0, 1, 1.5 and 2 L/ha as split dosage) were considered as subplots. The highest total dry weight of weeds (231 g/m2) was observed in the presence of conventional seedbed treatment and non-application of herbicide. The lowest dry weight of weeds was observed in the presence of stale seedbed with glyphosate and application of 2 L/ha of Oxyfluorfen herbicide. The highest bulb yield of garlic (580 g/m2) was achieved in the presence of glyphosate seedbeds with application of herbicide at 1.5 L/ha and the lowest bulb yield (91.2 g/m2) was observed in the presence of conventional seedbed and non-application of herbicide. In conclusion, application of 2 L/ha herbicide in split doses was recommended.
