| The experiment was carried out as factorial in randomized complete block design with three replications to evaluate of the best combination of weed management practices on yield and yield components of broomcorn in Mianeh region, East Azarbaijan, Iran, in the summer of 2008. Treatments included herbicides Foramsulfuron, Bromoxynil+MCPA and 2,4-D+MCPA, application doses recommended dose, 25% less and 25% more than recommended dose and weeding (with or without weeding). Results indicated that all Treatments had significantly effect on biological yield and grain yield of sorghum. Effect of herbicide and weeding was also significant, Application of Foramsulfuron produced highest biological and grain yields by 42.57% and 37.73%, respectively. Biological and grain yield was higher in weeding in comparison with non-weeding. Results indicated that all treatments had significant effect on harvest index and panicle emergence. Application of Foramsulfuron had the highest harvest index and panicle emergence, and was higher in weeding. |
