This study was carried out in Bayburt Merkez, Aydintepe and Demirozu districts in 2020 in order to determine the weeds, their densities and their incidence in the bean cultivation areas of Bayburt Province. Considering the product pattern around the area to be studied, studies were carried out in areas with different product patterns, using 1 m(2) frames in the inner parts of the area. Counts were made for each weed in the frame. As a result of the examinations, 26 weed species belonging to 26 genera belonging to 16 families, 1 from Monocotyledoneae and 15 from the Dicotyledoneae, were determined. It has been determined that the densities of these weeds vary between 0.02 and 5.29 plant m(-2) and the average density is 18.98 plant m(-2). As a result of the survey studies conducted on the basis of Bayburt province, the highest species in terms of average density and frequency of occurrence were Elymus repens (L.) Gould (5.29 plant m(-2); 68.46%), Amaranthus retroflexus L. (4.50 plant m(-2); 66.65%), Convolvulus arvensis L. (3.16 plant m(-2); 62.92%), Chenopodium album L. (0.87 plant m(-2); 31.86%) and Cirsium arvense (L.) Scop. (0.82 plant m(-2); 31.79%) and the least species were Setaria viridis (L.) P. Beauv. (0.07 plant m(-2); 5.67%), Ranunculus arvensis L. (0.07 plant m(-2); 4.76%), Chondrilla juncea L. (0.07 plant m(-2); 3.89%), Vicia cracca L. (0.06 plant m(-2); 5.56%), Boreava orientalis Jaub. and Spach (0.04 plant m(-2); 3.43%) and Isatis glauca Aucher ex Boiss. (0.02 plant m(-2); 1.54%). In the bean fields of Bayburt province, it is necessary to control weeds such as Elymus repens (L.) Gould, Amaranthus retroflexus L. and Convolvulus arvensis L. in order to increase the yield to be obtained from the unit area. For this, attention should be paid to bean varieties adapted to the region.
