Effect of urea and superphosphats fertilizer and it's thier interaction in some chemical properties of wheat grain (Triticum aestivum L.)

Abstract

An experiment was carried out by using post in kalar horticulture Station / Sulaimania province on soil taked from once region sields during growing season of 2008-2009. The objective was to study adding increasing levels of urea fertilizer which is ( 0.0, 0.20, 0.40, 0.80 ) gm /Pot and superphosphate fertilizer which is ( 0.0, 0.24, 0.48 ) gm / pot in some chemical properties of grain for wheat I P A 95. This experiment was carried out by completely randomized design (C. R. D) with three replications.Results in dictated of clear increase in all the studied characteristics (concentration for each nitrogen , phosphorus and potassium and carbohydrate percentage with increasing levels of fertilizers).
