The effect of chemical fertilizer (NK) and humic acid on top length, root length, root diameter, leaf area per plant, top fresh & dry weight and root fresh & dry weight of fodder beet (Beta vulgaris L. c.v voroshinger) was carried out in the Experimental Farm of Agriculture Faculty, South Valley University at Qena during the two seasons of 2016/2017 and 2017/2018 on sandy soil. A field experiment was conducted using a randomized complete block design in split- plots arrangement with three replications. Humic acid treatments were arranged in main plots while, fertilization treatments (NK) were allocated in sub-plots. The highest mean values of most previous traits were obtained from fodder beet plants which were supplemented by soil application of humic acid and 90kg N+100kg K₂O /fed. (H₁F₉). Based on these results, it is recommended to adding humic acid on soil and fertilization with NK by 90 Kg N + 100 kg K₂O per Feddan for fodder beet under similar soil and climate conditions.
