  • This study was conducted to establish of cropping system for year-round forage crops production in east-southern part of Korea and investigated their productivity and feed values. Cropping systems were tested in experiment using oat (cv. Highspeed and Darkhorse) in spring and autumn season, corn (cv. Kwangpyeongok) and sorghum (ss-450) in summer season and rye (cv. Gogu) and triticale (cv. Joseong) in winter season. Considering the forage productivity and feed value such as acid detergent fiber (ADF), neutral detergent fiber (NDF) and total digestive nutrients (TDN), this result suggest that three cropping system for year-round forage crops production. The combinations with triticale (winter), corn or sorghum (summer) and oat (autumn) were would be suitable ones. And also the combinations with rye (winter), corn or sorghum (summer) and oat (autumn) were would be suitable. If forage crops cultivation was started in spring season, the combinations with oat (spring), oat (autumn), triticale or rye (winter), corn or sorghum (summer) and oat (autumn) were would be appropriable. For the more suitable cropping system, we are proceeding on verification experiment of year-round forage crops.

  • The demand for the fresh leaf of hooker chive, which is mainly used as functional roots and contains dietary sulfur or saponin, is increasing, but the leaves are only harvested 3-4 times per year under conventional field conditions. A plant factory system with different light qualities or intensities was applied for year-round production of the fresh leaves. Hooker chive (Allium hookeri) roots were hydroponically cultured under the plant factory with a mixture of blue plus red LEDs (Light-Emitting Diodes) and fluorescent lights for 50 weeks. Maximum leaf growth was attained with the 1.5 dS/m EC in the culture medium under the plant factory. The average leaf and shoot numbers of hooker chive grown hydroponically under a mixture of 200 µmol/m2/s LEDs increased by 147% and 140%, respectively compared to those under 100 µmol/m2/s LEDs at the 10th harvest. The leaf length of hooker chive grown under the LEDs treatment with the lowest light intensity significantly increased by 27% compared with the natural light treatment at the 10th harvest. However, there was no significant difference in leaf pigmentation between natural and 200 µmol/m2/s LEDs treatments. Plant factory with the mixture LEDs of blue and red lights can be applied for year-round production of hooker chive fresh leaves to ensure a stable supply of leafy vegetable throughout the year.

  • This study was conducted to produce effectively more leaves of Angelica acutiloba through year-round production system by using various mulching materials and polyethylene(PE) tunnel. Soil temperature by covering treatment was higher in PE mulching and PE tunnel than in rice straw mulching, especially showing the highest temperature in PE tunnel from April through May. Water content of soil was higher in PE mulching than in non-mulching. Leaf production of Angelica acutiloba through year-round production showed the highest in PE tunnel and root production in PE mulching. These results suggest that leaf production of Angelica acutiloba can be maximized through PE tunnel cultivation system.

  • This study was conducted to produce effectively more leaves of Angelica acutiloba through year-round production system by using various mulching materials. Soil temperature by covering treatment was the highest in P.E.(Polyethylene Film) mulching and followed by rice straw mulching, especially showing highest temperature in Tr. PE(Transparent Polyethylene Film) from April through May. Water content of soil was higher in P.E. mulching than in non-mulching. Leaf and stem production of Angelica acutiloba through year-round production showed the highest in PE mulching also root production of Angelica acutiloba showed the highest in P.E. mulching. These results suggest that leaf and stem production of Angelica acutiloba can be maximized through P.E. mulching cultivation system.

  • 최근 우리나라 농업은 계속되는 농촌노동력의 감소 및 노령화ㆍ부녀화와 WTO체제 출범에 따른 농축산물 수입개방 둥 대내외적으로 매우 어려운 처지에 놓여있다. 이러한 농업여건변화에 따라 우리농업을 경쟁력 있는 강한 체질의 산업으로 육성하여 국제경쟁력을 키우고 국민소득 증대에 따른 고품질 농축산물 수요증가에 적절히 대응하기 위하여 품질이 좋은 농축산물을 값싸게 생산 공급할 수 있는 자본기술집약적 농업의 필요성이 점차 높아지고 있다. (중략)

  • 충남농업기술원 예산국화시험장에서는 자주색의 홑꽃 다화성 스프레이국화 신품종을 육성하기 위하여 모본으로 'T22319'를 부본으로 'SP02-037-13'을 인공교배 하여 'Yes Line'을 육성하였다. 이 품종의 주년재배 특성검정을 위하여 2004년부터 2007년까지 4년 동안 촉성, 억제, 자연일장재배를 하였다. 'Yes Line'의 자연개화기는 10월하순경이나 촉성 및 억제재배가 가능하다. 'Yes Line'은 홑꽃이고 꽃잎은 자주색이며 화심의 색은 진한 녹색이다. 꽃의 직경은 4.3 cm이고 화심의 직경은 1.2cm이며 착화수는 21.4로 다화성이고 절화수명은 16.5일로 긴 편이다. 개화반응주수는 7.5주이고 기호도는 3.86점으로 높은 편이며 고온기에도 화색이 변색되지 않고 품질이 안정되어 있다. 이 품종은 흰녹병에 대한 저항성이 강한 편이고 연중생산이 가능하다.

  • A total of 333 carcasses were evaluated for hindquarter traits: round weight, percent round, loin weight, percent loin, flank weight and percent flank. Other characteristics included: total retail, lean trim, fat trim, round steaks, rump, sirloin tip, loin steaks, percent loin steaks and flank steaks. Mating types included straightbred Angus and Santa Gertrudis, the reciprocal crosses of these two breeds and Gelbvieh ${\times}$ Angus. Breed of sire and breed of dam were significant for most of the traits evaluated. Calf year and slaughter group were also significant. This could be the result of environmental variations. Effect of sire within sire breed was non-significant for all the traits considered. Heterosis due to interaction between sire breed ${\times}$ dam breed was found significant for percent total retail cuts based on hindquarter weight. Generally, Santa Gertrudis purebreds were more desirable in cut out characteristics than all other breeding types followed by crossbreds of Angus ${\times}$ Santa Gertrudis.

  • 본 연구에서는 클러스터로 지정된 춘천의 애니메이션 산업의 특징을 분석하였다. 내적으로는 다른 지역의 클러스터와 차별화하기 위해 정책수행기관의 역할을 변화시키고 공동제작을 강화함과 동시에 실질적인 콘텐츠 제작단지의 건립을 시도함으로서 자체적인 문화콘텐츠 산업을 발전시키려 하고 있다. 한편, 외적으로는 공동제작을 주로 해외와 시도하면서 이러한 연결을 단순한 제작의 네트워크가 아닌 산업과 시장이 유기적으로 연결된 하나의 블록을 형성하려 하고 있다. 지방자치제 이후 자체적인 클러스터 운영이 국내의 다른 클러스터의 모습이나 성격과는 차별화되면서 국제적으로도 자체적인 네트워크를 이루어가고 있다는 점에서 의의가 있다.
