This study was carried out to investigate the growth characteristics, yield, chemical compositions and nutritive yield of whole crop barley varieties harvested in a paddy field. The experimental design was arranged in a randomized block design with three replications. The treatments consisted of five whole crop barley varieties (Yuyeon, Youngyang, Wooho, Dami, Soman). The planting date was on 21 October 2009 and the samples were harvested on 21 May 2010. Dry matter yield was higher in Youngyang and Dami than other varieties (p<0.05). Crude protein, crude fat, crude ash, ADF and TDN were not significantly different. Crude fiber was the highest at Dami (31.4%), and Youngyang (31.4%) exhibited the lowest crude fiber compared to other varieties (p<0.05). NDF was higher in the order of Wooho > Dami > Soman > Yuyeon > Youngyang (p<0.05). Total mineral content was higher in the order of Youngyang > Wooho > Dami > Soman > Yuyeon (p<0.05). The contents of both essential and non-essential amino acids were not different among whole crop barley varieties. Yields of crude protein was the highest in Wooho (p<0.05), and yields of mineral, amino acid, free sugar and TDN were the highest in Youngyang. Based on the results from this study, it can be suggested that Youngyang and Wooho showed to have higher productivity and high nutritive values compared to other varieties.
