The present study evaluated the effects of different dosages herbicides Oxyfluorfen and Trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. In this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was conducted in 2012 – 2013. The treatments were included the use of 1.5, 2 and 2.5 liters of Trifluralin per hectare, 1.5, 2 and 2.5 liters of Oxyfluorfen per hectare in one step, 1.5 liters Oxyfluorfen per hectare in two steps, a control with weed interference (two replications in each block) and a weeding and no weed control. Results showed that using different doses of herbicides significantly affected plant height, number of cloves per bulb, 100 seed weight, economical and biological yield and harvest index of garlic. The lowest economic yield was due to control treatment without controlling of weeds (540 g.m-2) and the highest was obtained under 3 treatments of 1.5 liter of oxyfluorfen herbicide (1661.67 g.m-2), hand weeding (1686.67 g.m-2) and split oxyfluorfen application (1670 g.m-2). Finally, oxyfluorfen treatment (1.5 liter) on 3 to 4 weeds leaf, were identified as the most appropriate treatments.
