  • This study was evaluated to compare annual productivity and feed value of Italian ryegrass and summer forage crops at paddy field in middle region of Korea. Italian ryegrass (Kowinearly) was used as winter forage crop, and forage rice (Youngwoo) and barnyard millet (Jeju) were used as summer forage crops. Each crop was cultivated using the standard forage cultivation method. The plant height, dry matter yield, crude protein content, and total digestible nutrient content of Italian ryegrass were 90.6 cm, 7,681 kg/ha, 9.2%, and 63.8%, respectively, and it was no significant difference by summer forage crops (p>0.05). The plant height of summer forage crops was the higher in barnyard millet than in forage rice (p<0.05). The dry matter, crude protein, and total digestible nutrient yields of summer forage crops were the higher in forage rice than in barnyard millet (p<0.05). Also, the feed value of summer forage crops was higher in forage rice than in barnyard millet. In conclusion, the combination of Italian ryegrass-forage rice was the most effective cropping system for annual forage production with high-yield and high-feed value, and it was considered the combination of Italian ryegrass-barnyard millet was good cropping system for annual forage production through reducing labor and cultivating stable at paddy field in middle region of Korea.

  • Importation pathway of rice cultivar into Korea was re-established with considering ancient geo-ecological characteristics of the Sororibyeo excavated from Cheongwon. It is assumed that Sororibyeo settled down in Korea by the importation pathway along the southern seashore of China through old downstream of Geumgang by a southern Korean human race when China and Korea were not yet separated each other by the Yellow Sea. This importation pathway was designated as "Old Geumgang-Sorori Rice Road", in this study. It is further inferred that Korean Peninsula was geographically isolated by ocean after the Ice Age. In consequence, Gawajibyeo, an ancient rice with little genetic variation, was evolved from Sororibyeo, which is estimated to evolve into rice cultivar in Korean Peninsula.
