Abstract

To evaluate competition ability of more and less competitive winter WHEAT cultivars on different WHEAT and WILD OAT DENSITY and WILD OAT competition on yield and yield components, an experiment was conducted at the research station of Plant, Pest and Disease Institute of Karaj, during 2003-2004 growing season with a factorial arrangement of treatments in a randomized block design with 4 replications. Result showed that Niknejad have more yield than Rooshan due to more DENSITY tolerating potential and more fertile tillers. Increasing WHEAT DENSITY cause decrease of fertile tiller/plant, seed/plant, 1000 seed weight and increase of spike/m2. By increasing of WILD OAT DENSITY, the rate of yield reduction was enhanced in two cultivars. At maximum WILD OAT DENSITY, recommended+25% and recommended WHEAT DENSITY had highest yield in Niknejad and Rooshan, respectively.
