Abstract
The experiment was carried out in agricultural season (2010-2011) at two locations, Talkief (35 km northern of Mosul) and Alnamrood (35 km eastern of Mosul). Two factors were selected for this experiment, tillage system with two levels (normal and zero tillage) and eight different treatment herbicides (Topic 70ml/ha, Granstar 20gm/ha, Lintur120gm/ha, Pallas 25L/ha, Chevalier 60gm/ha , Atlantis 36gm/ha). The experiment was designed as Randomized Complete Block Design in split plot with three replications and Duncan test were used to compare among the means of treatments. Zero tillage was superior as compared with normal tillage to decrease no. of narrow and broad leaves weed and their dry weights in the Talkief location while there was no difference between the two systems in Alnamrood. Zero tillage increased yield/m² in two locations significantly 237.37 and 313.983 kg/Donum for Talkief and Alnamrood respectively . All herbicides decreased in No. of narrow leaves at both locations. Topic herbicide was significantly decreased of the dry weight of narrow leaves at Talkief location while Pallas herbicide had similar effect at Alnamrood location. Granstar treatment decreased the number of broad leaves weed and dry weight both locations 5.33 and 6.8 (Talkief) 5.33 and 24.27 in Alnamrood . Chevalier herbicide highly decreased significantly the total yield of wheat 181,54 kg/Donum as compared with the check treatment 204,29 kg/Donum. The values of wheat yield obtain from Granstar and control treatment were much lower as compared with all others treatments.
