INTERACTION OF WILD OAT (AVENA FATUA L.) WITH DIVERGENT WHEAT CULTIVARS

Abstract

To elucidate the competitive ability of various cultivars of wheat with wild oats, field trials were established at NWFP Agricultural University, Peshawar, Pakistan for two crop seasons i.e. 2004-05 and 2005-06 using Randomized Complete Block (RCB) design having four replications. Each experiment comprised of 6 wheat cultivars viz., Khattakwal, Ghaznavi-98, Fakhar-e-Sarhad, Dera-91, Saleem-2000 and Pirsabak-85. In all the treatments, the wild oats was sown at a constant density of 10 plants m-2. Data were recorded on tillers m-2, plant height (cm), number of spikes m-2, leaf area tiller-1 (cm2), spikelets spike-1, spike length (cm), grains spike-1
