Abstract :
This study was carried out in order to determine weed species, their density and frequency in sainfoin fields in Askale, Center and Pasinler districts of Erzurum in 2007 and 2008. In this study, 79 different weed species belonging to 67 genus and 26 families (1 cryptogamae, 11 monocotyledoneaus and 67 dicotyledoneaus) were identified. Density of weed species varied between 1 and 2448 in square meter, and a density of 57.86 plant/m² of weeds per square meter on average were determined. At the experiment site were determined, the most common species Poa pratensis L. (Kentucky blue grass) (18.13 plant/m²), Poa bulbosa L. (Bulbous bluegrass) (14.25 plant/m²), Bromus tectorum L. (Downy brome) (7.05 plant/m²), Cirsium arvense (L.) Scop. (Canada thistle) (2.79 plant/m²) and Convolvulus arvensis L. (Field bindweed) (2.16 plant/m²); in addition to this study, the most frequent weed species observed were C. arvense (25.93%), C. arvensis (22.94%), P. pratensis (20.72%), B. tectorum (17.78%) and Rochelia disperma (L. fill.) C. Koch (14.80%).
