Abstract

In order to determine the pattern of weed emergence in potatoes the experiment was conducted in 2014-2015 at two places in agricultural research stations Alarogh and Samian in the city of Ardabil-Iran. Each week after potatoes planting emergence weeds in the constant sampling units inside the plots were transported to the laboratory in order to count and separation based on the results of this research, sampled weeds included 10 species and 7 families the highest germination and emergence of weeds occurred on average in 2-4 weeks after potatoes planting that's mean after receiving the 137 to 329 degree-days growth By potato in Samian station and 105 to 254 degree day in Alarogh station but the highest weed Density in both stations Alarogh and Samian belonging to the species of Amaranth and after the amaranth in Samian station the highest Density belong to the mustard compared to other weeds but also in this test, like amaranth, the lambs quarters in the third week belongs to the highest germination and Density and declined from the third week onwards germination of this species. Green foxtail weed Density in both studied stations had the highest rates in the third and fourth weeks equivalent to receiving the 233 to 329 degree day for Samian station and 177 to 254 degree day for Alarogh station but perennial weeds, field bindweed maintaining an emergence almost in the entire period. Other species observed in this experiment, were belonged the highest germination and emergence in 233 degrees day for Samian station and 177 degree day for Alarogh station. The results can be used for the accurate prediction the time of weed control operations.
