To investigate the effect of some cover crops incontroling weed, two experiments were conducted during the fall of 2018 at Namin in Ardabil province both with three replications.The first experiment was conducted in a randomized complete block design using four speacies of winter cover crops consisting of Rye (Secale cereal L.), Hairy vetch (Vicia villosa Roth), Chickling pea (Lathyrus sativa L.) and Hungarian vetch (Vicia panonica L.). The second experiment was conducted in a factorial design, based on randomized complete blocks with two sampling times: (before the end of cover crops growth (when the cover crops were green) and 40 days after the end of cover crops growth (when the cover crops were not green). The results showed that the highest total weed density was related to Hairy vetch and Chickling pea treatments (30.5 and 27 plant per square meter, respectively) and lowest weed density to Rye and Hungarian vetch treatments (17.5 and 22 plant per square meter) respectively. The results also showed that the highest total weed density was recooded from the second sampling time (30.33 plant per square meter) and the lowest total weed density (18.16 plant per square meter) was obtained from the first time of sampling. The highest levels of Shannon-Wiener and Simpson indices were related to the clusters of Hairy vetch, Chickling pea and Hungarian vetch.  Rye and Hungarian vetch cover crops, and the first sampling time (presence of green cover crops) were the most suitable types of cover crops and sampling times to reduce weed density. It can be inferred that there is a parallel relationship between plant biomass (establishment, overwintering and regrowth of cover crops) and weed density and dry biomass. Thus, with increasing biomass of cover crops, the density and biomass of weeds would decrease. Manuscript profile

To investigate the effect of winter cover crops on plant density, biomass of weeds and potato yield an experiment based on complete randomized block design with three replications was performed at Yingjeh Mullah Mohammad Reza village in Namin, Ardabil, Iran, in 2018. Treatments were rye (Secale cereal L.), hairy vetch (Vicia villosa Roth), chickling vetch (Lathyrus sativa L.) and Hungarian vetch (Vicia panonica L.). The results showed that the highest dry biomass was obtained from rye treatment (696 g.m-2), the lowest plant densities from its first and second sampling (9.3 and 23.6 plants per square meter, respectively. The lowest fresh and dry weed biomass from first sampling (175.8 and 52.2 g.m-2, respectively) were due to rye treatment. In addition, the lowest fresh and dry biomass of all weeds in the second sample indicated (377 and 134 g.m-2, respectively) were related to rye treatment. Also, the results indicated that the highest and lowest biomasses of weeds in both samples were related to the treatment of hairy vetch and chickling pea. The yield of potato tuber was not affected by the cover crops residues, and the effect of the cover crops did not different potato tuber yield significantly. The results show that rye has a significant effect on reducing the density, fresh and dry biomass of weeds in two sampling stages, but reduction in biomass of weeds does not necessarily indicate a positive effect of cover crops in the short term on improving crop yields.
