Due to the trend of population growth, the need to produce more potatoes by improving agricultural management is inevitable. One of the important challenges in agriculture is the management of weeds that, if not controlled, can lead to the destruction of agricultural products and decrease the productivity of agricultural lands. The use of chemical pesticides in agriculture in addition to being able to harm human and animal health, but also lead to environmental pollution and weed resistance to pesticides. For this reason, searching for non-chemical methods of weed management is of particular importance. Today, many believe that the key to successful weed control, especially in sustainable agricultural systems, is the use of cultivars with high competitive ability. This experiment was carried out in 1400-1401 and 1401-1402 on potato plant as a split plot in 3 replications. The first factor was the cultivation of three different potato varieties (Agria, Jely and Lady Rosetta) and the second factor included 5 types of management (complete weeding, rye cover crop, clover cover crop, paraquat herbicide and control). In total, rye, paraquat and clover treatments reduced the dry weight of weeds by 53.63%, 2.40% and 48.36%, respectively. Potato tuber yield increased by 63.75%, 53.21%, 47% and 1.72% in weeding, rye, clover and paraquat treatments compared to the control. According to the results, it was said that cover plants appeared effectively in reducing the density of weeds. The speed of height increase and the percentage of cover were also different in all three cultivars. In the trait of height Agria > Jeli > Lady Rosetta and in the percentage of cover Lady Rosetta > Agria > Jeli appeared.
