| To Study the effect of different plant densities of wild oat (Avena ludoviciana L.) on grain yield and yield components in three wheat (Triticum aestivum L.) cultivars, a field experiment was conducted as split plot in randomized complete block design with three replications in 2007-2008 cropping seasons in Mehran, Iran. The main plots were three cultivars (Chamran,Vee/Nac and Dez), and sub-plots were wild oat plant densities (0, 25, 50 and 75 plant.m-2). Results showed that wild oat plant density had significant effect on wheat grain yield and yield components. Increasing wild oat plant density from zero to 75 plant.m-2, grain yield of wheat reduced from 4786 to 4349 kg.ha1. Vee/Nac had higher grain yield in high plant density of wild oat as compared with Chamran and Dez. Results of this experiment showed that Vee/Nac cultivar may perform better grain yield under wild oat infection. |
