Abstract: The present experiment aimed to investigate the influence of humic acid application on qualitative traits of sugar beet cv.'Shirin' basis of a randomized complete block design with four replications during 2007-2008.The plants were treated with different humic acid treatments (control, 200, 300, 400, 500, and 600 kg ha -1 ).The sugar and non-sugar components such as potassium, sodium, amino-nitrogen and some qualitative parameters for sugar processing such as alkalinity of juice , root yield, sugar percent, recoverable sugar, and sugar content in molasses were determined according to the standard methods.According to the results, humic acid application enhanced sugar quality of sugar beet.The lowest value for K, Na and amino-nitrogen was observed in H300 treatment (300 kg ha -1 ) with 3.85 meq 100 g -1 pulp, 1.22 meq 100 g -1 pulp and 1.21 meq 100 g -1 pulp, respectively.The highest recoverable sugar content (15.64%) was obtained from 500 kg ha -1 application.Also, the highest sugar yield (18.41%) and the lowest sugar content in molasses (2.14%) were observed in the treatments of 400 kg ha -1 and 300 kg ha -1 humic acid, respectively.
