A field trail was conducted at the researches Farm of Agricultural College of Duhok University, Kurdistan Region/ Iraq, which located in semi-arid zone during the season 2016-2017 in two planting dates (28 November and 28 December 2016 ) to study the influence of four integrate Topic and granstar (0, 1200, 1600, 2000 ml. ha -1 and 0, 20, 40, 60 gm ha -1 ) and four phosphor fertilizer levels at (0, 183, 229, 275 kg ha -1 ) respectively, on weeds and bread wheat yield and its components. The experiment unit arranged in factorial experiment, using Randomize Complete Block Design (RCRD) with three replications. The results showed that herbicide and phosphorous levels exhibited significant effect on weeds and yield and its components. The treatment (Topic 2000 ml+60 g ha -1 granstar) produced maximum reduction in total weeds growth and recorded maximum values for 51.1 g) respectively. High dose of herbicide (Topic:2000 ml. ha -1 and Granstar,60 g ha -1 ) and high of of grains spike -1 , 1000-grain weight and grain yield which were (45.4, 42.5 g, and high phosphorus levels (275 kg ha -1 ) are recommended for weed control and high yield and a good quality wheat grains.
