영문 초록

This experiment was carried out to evaluate the effects of top dressing of nitrogen and harvest time 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. Top dressing was applied at seven separate growth stages, regeneration time (RT), and intervals of 20, 30, 40, 50, 60, and 70 days after RT, and harvested at different time from 20 days after heading (DAH) to 40 DAH with 10 days interval in split plot design with three replications. Plant height was increasing with earlier top dressing, but not affected by harvest time. Percent dry matter was increasing with earlier top dressing and later harvests. Protein content was increased with later top dressing and harvests, but percent NDF, ADF and TDN was not significant. Total anthocyanin content was increased with earlier top dressing, included increasing C3G (cyanidin-3-glucoside) and delphinidin. The C3G and delphinidin were detected from 25 DAH and P3G (pelargonidin-3-glucoside), cyanidin and perlagonidin from 30 DAH. Their contents were increased significantly as harvest was delayed. This experiment provides some interesting results with respects to optimum top dressing and harvest time for the functional feed production of the colored barley.
