This experiment was carried out to evaluate the effects of nitrogen top dressing levels on the growth, feed value, and anthocyanin content for developing functional feed of colored barley. A colored barley cultivar, Boanchalbori, was tested in this experiment. Nitrogen top dressing levels was six (0, 20, 40, 60, 80, 100%) and top dressing time was a regeneration time. In case of productivity, heading data was get behind and dry matter rate was significant decreased with higher nitrogen top dressing levels (p less than 0.05). Fresh yield, dry matter yield and TDN yield was increased with higher nitrogen top dressing levels, but not significant. In case of feed value, crude protein content was significant increased with higher nitrogen top dressing levels (p less than 0.05), and higher in the order of spike, whole and leaf culme of the plant. Percent NDF and ADF was decreased with higher nitrogen top dressing levels in leaf culme, but no difference in spike and whole (p less than 0.05), and higher in the order of leaf culme, whole and spike of the plant. TDN was increased with higher nitrogen top dressing levels in leaf culme, but no difference in spike and whole (p less than 0.05), and higher in the order of spike, whole and leaf culme of the plant. Total anthocyanin content was significant decreased with higher nitrogen top dressing levels in leaf culme and whole (p less than 0.05), and higher in the order of leaf culme, whole and spike of the plant. Specially, cyanidin-3-glucoside (C3G), delphinidin (Del), malvidin-3-glucoside (M3G) and malvidin (Mal) show a significant decrease. So there are an accumulation of anthocyanin in the culm, and standard nitrogen top dressing levels dressing on the regeneration time for produces high anthocyanin content of the colored barley.
