Abstract
An experiment was conducted in the plastic house at Kalar Horticulture Station , Province of Sulaymania , during the growing season of 2006/2007. The soil was brought from one of the Kalar region fields . The aim of the experiment was to study the interaction between gibberellic acid at concentrations of (0 , 25 , 50 , 75 and 100) ppm and two levels of NPK 18:18:18 which equal (40 and 80) kg /d equivalent to 0.32 and 0.64 gm/pot , on some chemical constituents of wheat plant grains . Factorial experiment within completely randomized design (C.R.D) with three replicates was adopted . Means were compared using ( L.S.D ) at 0.05 probability level . Results showed that , increasing GA3 concentrations and NPK lievels significantly increased N,P,K and carbohydrate content in the grains of wheat plants . The interaction between 75 and 100 ppm GA3 with 80 kg/d NPK was positive giving the highest valves of the studied characteristics .
