Abstract
In order to evaluate the effects of chemical and non-chemical weed management in in sugar beet, an experiment was carried out at a Research Farm in Karaj. The experimental factors were arranged in split-split plot based on a complete randomized block design with four replications. Planting pattern was allotted as main-plot (single row planting with 50 cm row width, single row planting with 60 cm row width and twin row planting with 60 cm row width), time of mechanical control as sub-plot (mechanical weed control at 4 leaves stage, 10 leaves stage and 14 leaves stage of sugar beet) and herbicides as sub-sub plot (metamitron plus combination of phenmedipham + desmedipham + ethofumesat and triflusulfuron metil plus combination of phenmedipham + desmedipham + ethofumesat). The results showed that planting pattern had proper effect on weeds biomass that best results were obtained in twin row planting 60 cm. Also, mechanical control at 4 leaves stage of sugar beet had the best effect on weeds density and biomass. metamitron plus combination of phenmedipham + desmedipham + ethofumesat had also the best effect on weeds density and biomass.
