| 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 non-sugar components such as potassium, sodium, amino-nitrogen and some qualitative parameters for sugar processing such as alkalinity, root yield, sugar percent, recoverable sugar, and sugar content in molasses were determined according to standard methods. According to results, humic acid application enhanced sugar quality of sugar beet. The lowest value of K, Na and amino-nitrogen were observed in H300 sample (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 300, 400, 500, and 600 kg ha-1 application. Also, the highest sugar yield resulted from 400, 500, and 600 kg ha-1 and the lowest sugar content in molasses were observed in the treatments of 200 and 300 kg ha-1 humic acid. | ||
