| Abstract Two experiments were caired out at the fields of al-musaib project-babylon city during two seasons , spring and autmn of 2007. in order to evaluate of plant populations and different weed control treatments on the yield and yield components zea mays L. Buhouth 106,and weeds ,using spilt plot design with three replications . plant populations D1 (89286),D2(119047) and D3(178571) plant /ha .were assigned in the main plots ,weed free ,one irrigation and plowing ,two irrigations and plowing one irrigation and glyphosate herbicide ,glyphosate herbicide ,igran herbicide in the sub –plots. Significant differences were found among plant populations in all studied characters in two seasons .The highest plant population (178571) plant /ha gave higher leaf area and grain yields (0.462,0.493) m2/plant and (3.726,4.713) tons/ha respevictley and decreased the dry weight of weeds .the lowest population in creased number of grain in ear and grain weight (320,395) and (0.256,0.265) g respevictly .the weed free gave high yield grain (4.848,6.003) ton /ha for the two sesons respevictly The smeared glyphosate gave (4.229,5.621) ton/ ha grain yield .The treatment D3 and weed free gave hieghest grain yield (5.622 and (7.875) ton/ha respevictley .The D3 and glyphosate gave (4.939,6.969) ton/ha respevictiey The result | ||
