Abstract
Aplastic pot experiment was carried out in privte field at Albargah district 30 km North east of Kerbala city longitude 44.14 degrees latitude and 32.41 degrees, during the winter season 2013 - 2014 Wheat plant (Triticum aestivum L.) were grown. A factorial experiment within completely Randomized design (C.R.D) with three replications was adopted . The first factor represents the three types of water is well , drainge and river water while the second factor represents the four concentrations of Gibberrellic acid is 0, 75, 150 and 225 ppm, giving 36 experimental units. activety of SOD and NPK concentration in the straw and grain. Results revealed that irrigation water types had significant effect on all studied Characteristics, River water treatment gave the highest values for most studied parameters, well weter gave highest values of leaves except (the concentration the SOD activety, the concentration of nitrogen in the grain, the protein in the grain), which was the lowest rate using the river water and well water using the above. The levels of Gibberellin significantly affected in all studied parameters except the concentration of nitrogen and potasum in the straw The third level of 150 ppm gave higher values of all studied parameters
