Response of some wheat growth traits for for foliar spraying with humic and glutamic acid

Abstract

A field experiment was conducted at the Agricultural Experiment Unit, College of Agriculture Engineering Sciences, University of Baghdad, during two winter seasons 2016-2017 and 2017- 2018 to study the response of some growth traits for wheat Cv. Al forat to foliar spraying using with humic glutamic acid and acid. A factorial experiment was with in Randomized Complete Block Design applied three replications, it involved two factor ,first factor was glutamic acid with three concentrations (0,250,500) mg L-1, second factor was humic acid with three concentrations (0,1,2) ml L-1, have been sprayed at tillering and flowering stages. The results showed that all the studed growth traits (plant height, number of tillers, flag leaf area dry weight for plant, crop growth rate, relative growth rate and biological yield) were affected by spraying with humic acid and glutamic acid for two season concentration , 2ml -1 from humic acid was superior on most of studies traits, as for glutamic acid ,plants treated with concentrations 250 and 500 mg L-1 were produced the highest mean for studies traits but without significant difference between them in some traits.The interaction between two factors was significant on most studies growth traits.
