The Effect of Interaction Bbetween the Fertilization by (NPKZn) and the Spraying by Gibberellin in Some Qualitative and Rheological Characteristic for Three Varieties of Iraqi Wheat.

Abstract

Experiment carried out in the fenced area of botanic garden in the Department of Life Sciences, Faculty of Education Ibn al-Haytham, Baghdad University. During the growing  season of 2013-2014 to determine the NPKZn fertilizer and spraying of  four concentrations of Gibberellin (25,50,100 and 150) mg.l ^-1 and  the interaction between them in addition to the control treatment  in the quality and rheological characteristics of three varieties of the Iraqi wheat (Bhooth 22,AL-fatih and bhooth 128). The layout of the experiment was (R C B D) with three replications. Results showed significant differences between the fertilizer application in all studied characters, and that spraying with 100 mg. liter ^-1 Gibberellin and gave the highest averages for quality and rheological characteristics except flour recipe portability absorption of water, the interaction between the level of 160 kg.h^-1 of manure and spraying Gibberellin significant differences for each of the characteristics compared with the control treatment except for ashes ratio of coarse bran.
