Competition of Wild Oats (Avena Fatua l.) With Different Wheat Cultivars

A field trial on competitive ability of various cultivars with wild oats density was conducted at NWFP Agricultural University, Peshawar, Pakistan during the crop season of 2005-06. The experiment was arranged in RCB design with six cultivars namely Khattakwal, Ghaznavi-98, Fakhar-e-Sarhad, Dera-91, Saleem-2000 and Pirsabak-85. In all plots of the wheat wild oats was sown at a constant density of 10 plants m-2. In the study effect of wild oat on some morphologic, growth and yield parameters of wheat was observed. Also some characteristics of the wild oat like tillers, seed per plant, plant height and leaf area were measured in the wheat cultivars. Most of the wheat parameters were significantly affected by wild oats infestation. Saleem-2000 and Ghaznavi-98 showed comparatively more vigorous growth and as result suppressed wild oat density. On the bases of present experiment highest yield and yield components were recorded for wheat cultivar Saleem-2000
