In order to evaluate the effects of integrated weed management treatments on some growth parameters of potato (Solanum tuberosum L.), a field experiment was conducted at the field of Ardebil Agricultural Research Center in 2011. This study was arranged based on randomized complete block design with 8 treatments and 3 replications. The experimental treatments were including 6 integrated weed management treatments, hand weeding and weed-infested treatment during entire growth season. Weed management treatments had significant effect on stems number per plant, tuber dry weight and weed density. The highest and lowest tuber weight was observed in cultural-mechanical and natural-mechanical management, respectively. The lowest weed density was observed in chemical-mechanical weed management that had no significant difference with hand weeding treatment that shows this management is useful for reducing the weed density. Regarding to the potato tuber dry weight and weed density the cultural-mechanical, cultural-chemical-mechanical and cultural-mechanical-natural managements are recommended. Also vinegar application in combination with cultural and mechanical control could be an alternative for herbicide application.
