Abstract
This study was conducted by using plastic pots in the Department of Biology- College of Education for Pure Sciences / University of Karbala for the season (2011 - 2012), to study the effect of the interaction between different levels of water stress and the addition of potassium on vegetative growth indicators of plant wheat, which included (plant height , Leaf area, number of, number of leaves, dry weight of root system, dry weight of shoot) at elongation stage. Factional experiment within a Completely Randomized Design (C.R.D.) with three replications was applied . The experiment included three concentrations of potassium (i.e. 0, 100 and 200) kg K.ha-1 , and three water stress levels depending on the field capacity at the amount (100%, 75%, 50%). The experiment included 27 pots (experimental unit).The data were been analyzed and means were compared using L.S.D at 0.05 probability level. The most important results that could be summarized as follow: one hundred field of capacity treatment gave the highest values of the studied traits(plant height, number of leaves, number of tillers, leaf area, dry weight of root system, dry weight of shoot). Results also showed that addition of potassium at (200) kg K. ha-1 gave the higher values for the above-mentioned traits. Meanwhile the results a significant interaction between the levels of water stress and potassium giving a various effects on the studied traits.
