This study was conducted to find out that winter green manure crops could be efficient replacements of expeller cake fertilizers, which were mostly imported, on environment-friendly red pepper production. Four treatments were compared under the condition of plastic film house: 1) barley (B); 2) hairy vetch (HV); 3) mixtures of barley and hairy vetch (B/HV); 4) expeller cake (EC). Total nitrogen content in hariy vetch was 3.6%, which was higher than 1.5~1.8% in barley and mixtures of barley and hairy vetch. P₂O₅ and K₂O contents were similar in all green manures. Supplying amount of nitrogen from B, HV and B/HV plot, which were 172 kg ha^-1, 193 kg ha^-1, and 198 kg ha^-1, were higher than amount of basal nitrogen required by soil testing but were lower than that of total nitrogen, respectively. Among the green manure crops, C/N ratio of HV was the lowest at 11.8, showing a similar value to that of expeller cake, but that of B was the highest at 30.6. Total yield was no significant difference in all treatment plots although B/HV plot showed the highest yield, but initial yield in B plot with high C/N ratio was lower than that in EC plot.

To control the pepper anthracnose caused by Colletotrichum acutatum, antifungal bacterium strains which was selected among bacterium from natural soil, was tested the antimicrobial activity against various pathogens and its control efficacy on anthracnose disease in the fields. We confirmed that antagonistic activity of CAB13001 strain to pathogens such as Sclerotinia cepivorum, Sclerotinia sclerotium and Botrytis cinerea including Colletotrichum acutatum was remarkable superior with the dual culture method in the artificial medium. In vitro bioassay using the green pepper fruit, CAB13001 strain suppressed the lesion development of Anthracnose disease, and its control value compared to the untreated one was 82.4% on pepper fruit in field test. These results suggested that CAB13001 strain could be a very useful biological control agents to anthracnose disease caused by air born plant pathogens of pepper. By the way, analysis of nucleotide sequence of the gene 16S rDNA, antagonistic bacterium CAB13001 strain used in this study was identified as Burkholderia lata.

WTO체제에서 국제 경쟁력을 갖추기 위한 전략의 하나로 친환경농업을 추진해온 우리나라 농업은 환경오염의 경감과 농업의 다원적 가치의 실현을 위한 친환경농업 전문가 양성이 시급하며 이를 대학 교육에서 담당할 필요성이 높아지고 있다. 본 연구에서 4개 사례 대학의 교과과정 분석 결과 한국의 농학계 대학에서 이루어지고 있는 환경 교육은 대부분의 대학이 대학의 명칭이나 학과의 명칭을 변경하는 과정에서 생명, 자원, 환경을 포함시키고 교육 목표에서도 환경과 관련된 내용이 제시되고 있으며, 교육과정에 환경오염방지 및 개선에 관계된 과목을 설강하여 학생들에게 수강하도록 하고 있다. 또한 농업의 위치와 사회적 역할로서 농업의 다원적 기능과 농업과 환경에 대한 강의가 일부 대학에서 이루어지고 있으며, 비농업 전공자들에게도 호응을 얻고 있다. 그러나 현재 이루어지고 있는 환경교육은 별도의 농업환경 교육과정이 마련되어 있지 않으며, 설강된 과목들도 연계성이 부족하고, 전공과목 우선으로 수강하게 되므로 그 비중이 매우 적은 실정이다. 따라서 농업환경 교과과정을 별도로 개발하여 학생들로 하여금 체계적인 교육을 받도록 할 필요가 있다. 앞으로 환경분야에 대한 사회적 직업 수요가 증가함에 따라 농학의 수요는 더욱 증가할 것이며 환경평가나 환경계획 관련 분야 및 영농현장이나 관련 기관에 종사할 인력들에게 있어서도 대학에서의 체계적인 교육이 필요하다.

These experiments were conducted for 3 years from 2021 to 2023 to develop a method that can be safely used to prevent the leakage of Golden apple snails (Pomacea canaliculata) from eco-friendly rice plantations. In the southern part of Jeollanam-do, after planting rice, the young golden apple snails placed in the rice field become adults around mid-July and begin spawning. These individuals can overwinter in drains that do not dry out, but individuals hatched after mid-July will not mature enough to overwinter. The size of golden apple snails overwintered in the drainage canal was more than 2.5cm in shell height. Installing a net at the inlet could block 95% of the inflow of snails, and 99% of outflow was blocked by installing an improved water trap and net at the drain. During the mid-drying period and pre-harvest drying period, a water path was created with a power paddy pottery machine. 59.5% of snails were attracted to the waterway, and it took 130 minutes to build the waterway and collect the snails. Based on these results, seasonal paddy management tips for the safe use of giant snails in rice fields were suggested.

The Korean Ministry of Agricultural & Forestry(MAF) has designated some model areas and has supported financially to encourage sustainable farming under the environment-friendly agriculture rearing project(EARP) since 1995. This study was conducted to diagnose the project and to find ways to improve the effectiveness of EARP. The 18 areas (823 ha) such as Gyeonggi-Do, Gangwon-Do, Chungcheongbuk-Do, Chungcheongnam-Do, and Jeju-Do of 32 areas under EARP in 2004 were examined. Most of the practices implemented in EARP areas were not practical for sustainable agriculture except some equipments and facilities. It was thought that practical technologies for sustainable agriculture were more essential than equipments and facilities to improve the effectiveness of EARP. And area-specific technologies are needed to decrease environmental pollution. For example, liquefied slurry application and duck-rice farming in paddy fields near a watershed could increase the possibility of water pollution by nutrient outflow. Soil characteristics were important factors that could affect the effect of practices on environment conservation. Woodchip application and subsoil crash were not effective in coarse-textured soils. It was recommended that every practices under EARP should be re-examined in the light of the effects on environment before implementation and be evaluated by experts after completion.
