In order to study the effect of different doses of metribuzin and plant density of wheat on weed control, an experiment was conducted at the Iranin Research Institute of Plant Protection, Karaj, Iran during 2007-2008. The experiment was conducted in randomized complete block design with factorial arrangement of treatments. Treatments were wheat densities at three levels of 400, 500 and 600 plant.m-2 and metribuzine doses at five levels of 0.0 0.2 , 0.4, 0.6, and 0.8 Kg.ha-1. Results indicated that the best control of weeds and wheat grain yield was obtained in combination treatment of 500 plants.m-2 wheat density and 0.8 Kg.ha-1 metribuize. Results showed that wheat density can be used as a tool for reducing herbicide dose and weed damage in an integrated weed management program in wheat.
