This study was conducted to investigate the effect of mixed-sowing of legume forage and applying of cattle manure on the productivity of rye in order to produce the organic roughage to be effectively reducing the environmental contamination and to provide Hanwoo rearing farmer with safe organic animal products. The present study also aimed to evaluate optimal applying level of cattle manure and carrying capacity of Korean native cattle (Hanwoo) per unit area. The annual amount of crude protein (CP) of rye in Gyeongju were higher than those of in Gyeongsan and Yeongju, and the mixed-sowing of forage pea was the highest (p<0.05) compared with the single-sowing. The amount of CP were increased proportionately corresponded to the applying level of fermented cattle manure, and found significantly (p<0.05) high at the level of 100 and 150 kg/ha groups. With feed value of forage, CP was tended to be higher in the mixed-sowing of legume than the single-sowing of rye at the wintering experimental sites of legume, and in particular the forage peas was higher (p<0.05) than other crops. Carrying capacity of organic Hanwoo (head/ha) was higher (p<0.05) in Gyeongju (3.28 head) than that in Gyeongsan (1.94) and Yeongju (1.50). The carrying capacity in the single- sowing of rye also was lower than that in the mixed-sowing of legume, and the forage peas was the highest among the mixed-sowing groups (p<0.05). Overall, the present results showed that it would be recommended to take into account the wintering for mix-sowing of legume. The fermented cattle manure may be applied for legume in the wintering unavailable regions. In addition, the applying the fermented cattle manure at the level of 100~150kg/ha and the mix-sowing of legume with forage peas may increase the productivity per unit area and feed value including CP for improving carrying capacity of organic Hanwoo.
Abstract
This study was conducted to investigate the effect of mixed-sowing of legume forage and applying of cattle manure on the productivity of rye in order to produce the organic roughage to be effectively reducing the environmental contamination and to provide Hanwoo rearing farmer with safe organic animal products. The present study also aimed to evaluate optimal applying level of cattle manure and carrying capacity of Korean native cattle (Hanwoo) per unit area. The annual amount of crude protein (CP) of rye in Gyeongju were higher than those of in Gyeongsan and Yeongju, and the mixed-sowing of forage pea was the highest (p<0.05) compared with the single-sowing. The amount of CP were increased proportionately corresponded to the applying level of fermented cattle manure, and found significantly (p<0.05) high at the level of 100 and 150 kg/ha groups. With feed value of forage, CP was tended to be higher in the mixed-sowing of legume than the single-sowing of rye at the wintering experimental sites of legume, and in particular the forage peas was higher (p<0.05) than other crops. Carrying capacity of organic Hanwoo (head/ha) was higher (p<0.05) in Gyeongju (3.28 head) than that in Gyeongsan (1.94) and Yeongju (1.50). The carrying capacity in the single- sowing of rye also was lower than that in the mixed-sowing of legume, and the forage peas was the highest among the mixed-sowing groups (p<0.05). Overall, the present results showed that it would be recommended to take into account the wintering for mix-sowing of legume. The fermented cattle manure may be applied for legume in the wintering unavailable regions. In addition, the applying the fermented cattle manure at the level of 100~150kg/ha and the mix-sowing of legume with forage peas may increase the productivity per unit area and feed value including CP for improving carrying capacity of organic Hanwoo.
