| Abstract | ||
| In order to study the impacts of mechanical (using cultivation), chemical (using herbicides) methods and their integration in controlling broadleaf weeds in sugar beet fields, this experiment was carried out as a randomized complete block design with 4 replications in Mahidasht-Kermanshah in 2006. In this experiment, 9 different treatments consisting a mixture of post-emergence herbicides phenmedipham + desmedipham + Ethofumesate and Triflusulfuron Methyl with Sittogate combined with cultivation and 2 check treatments with and without control of the weeds were investigated. The results indicated that cultivation treatment accompanied by Triflusulfuron Methyl reduced dry weight of weeds by 54.91% and showed 100% control of Amaranthus spp. In comparison with control treatment. Cultivation treatment combined with a mixture of phenmedipham+desmedipham+Ethofumesate and Triflusulfuron Methyl with Sittogate increased the sugar beet root dry weight by 159.89% and caused 100% control of the density of Conringia orientalis. Phenmedipham+desmedipham+Ethofumesate plus Triflusulfuron Methyl with sittogate treatment increased root yield by 121.86% compared to the check. In conclusion, the highest root yield was obtained in the cultivation treatment combined with phenmedipham + desmedipham+Ethofumesate, a mixture of phenmedipham + desmedipham + Ethofumesate and Triflusulfuron Methyl with Sittogate and cultivation treatments in sugar beet. | ||
