This study was carried out using plastic pots in the Department of Biology- College of Education for Pure Sciences / University of Karbala during the growing season (2013 - 2014), in order to study the Effect of the overlap between different levels of water stress and potassium added in vegetative growth indicators to plant wheat, which included (plant height , Leaf area, number of branches, number of leaves, Dry weight of root system, Dry weight of shoot) at booting stage. Factional experiment within a completely randomized design (C.R.D.) with three replications was applied . The experiment included three concentrations of potassium (0, 150 and 200) kg K.ha-1 , and three levels of stress irrigation water by adding water amount (100%, 75%, 50%) of the value of the field capacity. The experiment included 27 pot (experiment unit).The result has been analyzed and means were compared using L.S.D at 0.05 probability level. The water level 100% of the value of the field capacity gave the highest values of the studied traits(Plant height, number of leaves, number of branches, leaf area, Root dry weight system, Shoot dry weight). The results also showed that the added concentration of potassium (200) kg K. ha-1 gave higher values for the above-mentioned traits.Meanwhile showed bilateral interactions between the levels of water stress and potassium added showed a various effect on the studied traits.
