시설 고추 주요 해충인 꽃노랑총채벌레(Frankliniella occidentalis)의 방제를 위해 유기농업자재들의 단독 처리 및 종합 투입시 방제 효과를 검정 하였다. 황색끈끈이롤트랩은 지제부에 설치하고, 포식성 천적(Hypoaspis miles)은 지제부에 접종하며, 식물추출물(커스터드애플시드 오일 50% + 계 피 추출물 10%)은 경엽살포하는 방식으로써 각각의 단독 처리시 방제 효과는 45.3, 36.6, 50.2%였다. 한편, 3종의 유기농업자재들을 종합 투입했을 경우 고추 수확기 방제 효과가 무처리 대비 62.4~80.9%로 유지되어, 시설 고추 꽃노랑총채벌레 친환경 방제용으로 활용이 가능할 것으로 생각된다.

본 연구는 도시농업의 다원적 기능 활성화를 위한 도시농업 조례 개선 방향을 제시하기 위해 도시농업 조례 제정 현황과 광역지방자치단체 도시농업 조례 내용 중 다원적 기능 지원에 관한 부분을 분석하였다. 그리고 조례 지원이 상대적으로 미비한 기능을 대상으로 조례 개선 방안을 도출하고 델파이 조사를 통해 이를 검토하였다. 연구 결과 2023년 3월 기준 17개 광역지방자치단체 중 12개, 기초지방자치단체 226개 중 116개에서 도시농업 조례를 제정한 것으로 확인되었으며, 연간 도시농업 조례 신규 제정 개수는 2011년 이후 대체로 감소하는 추세를 보였다. 도시농업 조례 내용 분석 결과, 현행 조례는 주로 도시농업의 기반 조성과 확대에 관한 사항을 중심으로 구성되어 있다. 도시농업 의 다원적 기능에 대한 지원 근거 분석 결과, 도시농업의 다원적 기능 중 녹지 확보 및 활용, 식량 생산 기능의 지원 근거가 가장 많이 마련되어 있다. 반면 자원 재활용, 치유 및 보건, 사회복지, 경제 불균형 완화, 일자리 창출 기능에 대한 지원 근거는 상대적으로 미비한 것으로 나타났다. 이들 기능을 지원하기 위한 도시농업 조례 개선방안을 도출하여 델파이 조사를 진행한 결과, 18개 개선방안 중 17개 방안이 타당한 것으로 나타났다. 따라서 도시농업의 다원적 기능을 활성화하기 위해 우선 도시농업 조례를 아직 제정하지 않은 지방자치단체의 조속한 조례 제정이 필요하다. 그리고 자원 재활용, 치유 및 보건, 사회복지, 경제 불균형 완화, 일자리 창출 기능에 관한 내용을 포함하는 방향으로 조례를 개정하는 것이 필요하다. 그 과정에서 도시농업 기술 개발, 다양한 도시농업 공간에 대한 법적 검토, 도시농업 관련 산업 육성 등이 함께 이루어져야 한다. 무엇보다 도시농업의 다원적 기능에 관한 꾸준한 관심과 지방자치단체의 도시농 업 육성 노력이 뒷받침되어야 한다.

This study developed an IoT-based agricultural well control system and demonstrated it through a control system in the current state of domestic open-field smart farms where systematic management is insufficient due to the difficulty of collecting accurate data such as agricultural water intake and usage. As a result, it was possible to derive the optimal control system test results according to the watering conditions for each schedule by conducting automatic control focusing on periods when there is no precipitation. This means that irrigation can be carried out smoothly during the time when irrigation is needed to improve crop quality and secure farm income, and as a result, it is possible to systematically manage and operate among demonstration farms connected to irrigation, resulting in a shortage of agricultural water and a resolution of supply imbalances.

This study investigated the diversity of butterfly communities inhabiting agroecosystems and examined the effect of latitude and longitude. The ecological characteristics of butterflies inhabiting rural ecosystems, such as habitat preference and food plant range, were also examined. This study was conducted from 2019 to 2022, selecting 10 locations nationwide and conducting line transect surveys every two weeks for four years, confirming a total of 112 species and 21,901 individuals. There was no difference in the number of species and individuals by region, but there was a clear difference in community composition. The most abundant species in rural ecosystems were Pieris rapae, Polygonia c-aureum, Zizeeria maha, and Colias erate, in that order. There was no significant difference in the number of species and individuals by latitude and longitude, indicating no peninsula effect. Habitat preference showed that butterflies preferring grasslands and forest edges were much more common than those preferring the forest interior, and the food breadth was mostly oligophagous, followed by monophagous and polyphagous. Butterflies inhabiting agroecosystems had ecological characteristics that preferred open spaces such as grasslands and forest edges or relatively diverse foods, due to the similarity of the environmental characteristics of the survey points. Through this study, we believe that continuous monitoring is necessary to determine whether climate change, which is currently underway and habitat change are affecting butterflies in agroecosystems.

The insecticidal activities of 27 different commercial products with environmentally friendly organic material (EFOM) against Scotinophara lurida, a major rice pest, were evaluated in the laboratory using spraying methods on plants and insects. Seven plant-derived organic farming materials (EFOM-8, -10, -12, -13, -19, -20, and -26) with high insecticidal effects when sprayed directly on the insect’s body rather than on the plant were selected. In the indoor rice pot test, all 7 EFOMs showed an insecticidal rate of over 73.3% under irrigated conditions. Notably, EFOM-13 and EFOM-20 demonstrated much higher insecticidal rates, ranging from 1.5 to 1.8 times, in irrigated conditions compared to drained conditions. In the semi-paddy field test, EFOM-10 (80% garlic extract), EFOM- 13 (62% neem extract), and EFOM-26 (70% sophora extract+28% ethyl alcohol+2% pyrethrum extract) exhibited a higher control value of 88.9% in the irrigated paddy on the 7th day, surpassing the control values in the drained paddy by 1.4 to 1.9 times. The control value in the irrigated rice paddy field sprayed with EFOM-10 reached 86.2% on the 7th day, which was 1.4 times higher than 61.9% in the drained paddy. Taken together, the findings suggest that direct contact of the insect’s body with sufficient amounts of spray solution and the maintenance of paddy irrigation can enhance the controlling effect of EFOMs. These findings will be valuable in developing an optimal S. luridacontrol strategy for application in rice paddy fields in the near future.

The blockage rate for three kinds of nets commonly used in agricultural facilities was assessed by using the image acquisition and its relevant processing. By using both empirical relations presented by Idel’chik and Richards and Robinson, and the blockage rate obtained from the image processing, the pressure drop through the nets was predicted and also compared with wind tunnel experiment results. The results of the study showed that the blockage rate of the net was discriminated according to such factors as the magnitude of nets, the existence of inside threads, the thickness and number of threads. In addition, the blockage rate for the incident angle of 0° when the wind blew at the front had the range of 0.22－0.29 (0.22－0.32 when considering whole incident angles from 0° to 45° by 15°). For the nets with the blockage rate of about 30% or below, the prediction by the empirical relations of by Idel’chik and Richards and Robinson showed a little higher pressure drop overall than that of the wind tunnel test, but the use of the empirical relations and the blockage rate could be thought of as providing effectively meaningful guidelines for the safe design of agricultural facilities including nets because the wind tunnel test has been tedious and expensive. Further research and potential application on the prediction technique of the pressure drop, regarding both a subtle deformation by the wind and manufacturing methods with regard to the level of knots and the existence of inside threads, needs to be done for the nets with higher blockage rate.

This study was conducted to evaluate Korean rice cultivars to search any suitable varieties for the northern region of the Korean Peninsula (North Korea). A total of 92 rice varieties which included 74 bred cultivars from South Korea, 13 collections from North Korea and five local cultivars from China, were involved in the evaluating trials for their performance. Stability at three sites inthe northeastern areas of China, which are located in the northern border areas of North Korea, for three years from 2017 to 2019. The ecologically well-adapted rice varieties were selected at each trial site during the first year and employed again as the materials for the subsequent yield trials. A total of six varieties with relatively better performing and stability were selected through the subsequent trials at three sites for three years: Unkwang, Daejin and Taebaek at Dandong region; Hanseol and Taebong at Longjin region; Taebong and Namweon at Hunchun region, respectively. Dandong is located in the southeast parts of Liaoning, which has similar climatic characteristics to the west coastalregion of North Korea. Longjin is located in the middle-east parts of Jilin, which has also similar climatic characteristics to the northern inland region of North Korea. Hunchun is located in the northeastern parts of Jilin, which has presumably similar climatic characteristics to the northern part of the eastern coastal region of North Korea. Unkwang is characterized by its early maturity, with the heading at the 2nd of August, and reveals a yield potential of 7.11 T/ha with resistance to the blast (BL) and the bacterial leaf blade (BLB) diseases. It is predicted to be suitable for the northern area of the Suyang mountain region and the central inland region of North Korea. Daejin has asemi-early maturity heading around the 6th of August and yields of 6.06 T/ha with resistance to BL, BLB, and stripe virus (SV) diseases. Daejin will be adaptable to the northern area of Suyang mountain region. Taebaek is medium maturing variety of Indica/Japonica type. It is heading at the 14thof August with good ripening at maturity, and has yield potential of 6.84 T/ha with resistance to BL, BLB and SV diseases. It will be adaptable to the southern area of Suyang mountain region. Hanseol is early maturing, heading on the 3rd of August, and yields 6.44 T/ha with the short stature and cold tolerance (CT). It will be adaptable to the northern inland and mountainous regions of North Korea. Taebong is semi-early maturingwith the heading at the 6th of August and has a yield potential of 6.96 T/ha with cold tolerane and blast resistance. Taebong was also outstanding in theHunchun region, indicating a more or less wide adaptability in cold areas. It is expected to be adaptable to the northern inland region of North Korea as well as the northern part of the eastern coastal region. Namweon is a medium-maturing variety with aheading date of August 10, and a yield potential of 4.76 T/ha with cold tolerance and resistance to rice neck blast disease. It is expected to be adaptable to the northern part of the eastern coastal region.

This study examines and proposes standardization approaches to address the heterogeneous issues of metadata in drone imagery within the agricultural sector. Image metadata comes in various formats depending on different camera manufacturers, with most utilizing EXIF and XMP. The metadata of cameras used in fixed-wing and rotary-wing platforms, along with the metadata requirements in image alignment software, were analyzed for sensors like DJI XT2, MicaSense RedEdge-M, and Sentera Double4K. In the agricultural domain, multispectral imagery is crucial for vegetation analysis, making the provision of such imagery essential. Based on Pix4D SW, a comparative analysis of metadata attributes was performed, and necessary elements were compiled and presented as a proposed standardization (draft) in the form of tag information.

This study identifies the commercialization success factors that can be an important indicator for the transfer and commercialization of national R&D results in the agricultural sector. Unlike other industries, the agricultural sector has a non-systematically scaled and processed industrial structure, and R&D is led by government rather than the private sector. Although the quantitative performance of national agricultural R&D, especially the number of patents and publications, has increased rapidly with the quantitative expansion of the government R&D budget, the technology commercialization of the results of agricultural R&D has been accompanied by difficulties for SMEs. Therefore, this study summarized the success factors for commercialization of state-owned technologies presented in previous studies, and based on them, analysed the success factors for commercialization specific to the agricultural sector. It also conducted a questionnaire survey using Delphi and focus group interviews (FGI) with experts from academia, research and industry, and a survey of agricultural companies to derive success factors for commercialization in the agricultural sector using logistic regression analysis. As a result, five indicators with positive correlation and three indicators with negative correlation within technology characteristics, suppliers, adopters, policy and market factors were finally derived as key factors for agricultural commercialization. In the future, it is expected that independent factor analysis of the food and seed sectors, which have independent industry characteristics from the agricultural sector, will be needed.

본 연구는 등유를 사용하는 농업용 난방기에서 배출되는 가 스를 포집하고, 농업용 난방기의 사용 연식에 따른 이산화탄 소의 배출농도를 파악하고자 수행되었다. 선형 회귀분석의 결과로 농업용 난방기의 연식에 따른 이산화탄소의 배출량은 R2 = 0.84로 y = 26.99x+721.98의 식을 따른다고 나타났다. 농업용 난방기의 사용 연식에 따라 세 그룹으로 분류하여 분 산분석을 수행하였다. 분산분석을 수행한 결과, 분석을 위해 설정한 유의확률 0.05보다 작은 2.1961×10-13으로 나타났으 며 이는 적어도 한 그룹에서 차이가 나타난다는 것을 의미한 다. 본 연구에서는 농업용 난방기의 기본적인 배출농도의 차 이를 분석하고자 기기의 제작사와 상관없이 농업용 난방기의 기기 연식만을 고려하여 배출가스 데이터를 수집하였다. 기 기의 연소 방식에는 제작사에 따라 연소 방식에 차이가 미미 하게 있었을 것으로 판단되며 데이터 변수의 개수가 늘어난다 면, SVR(support vector regression) 기반의 선형회귀 분석 등 을 실시하여 농업용 난방기의 이산화탄소 데이터가 온실가스 발생량 파악에 더욱 활용도가 높아질 것으로 판단된다. 추후 연구에서는 더욱 세분화된 데이터의 수집 방식을 따라 더욱 높은 정확도를 가진 결과값을 도출할 수 있다고 판단된다. 이 처럼 우리나라의 농업 분야에서 용도별 온실가스 발생량을 조 사하기 위하여 고정형 농기계인 농업용 난방기의 이산화탄소 발생량을 정확히 파악하여 온실가스 배출량 조사에 활용할 수 있을 것으로 판단된다.

이 연구는 한국과 호주 간 양자 협력 의제 중 자원 안보와 밀접한 관 련이 있는 탄소중립 기술 개발, 핵심 광물 공급망 그리고 농업 협력을 중심으로 살펴본다. 탄소중립 기술과 핵심 광물 공급망 같은 경우 2021 년 양국의 포괄적 동반자 관계 수립 이후 급격하게 협력이 시작되었고 정부와 주요 기업들이 적극적으로 참여하였다. 이에 반해 농업 협력은 2014년 양국의 자유 무역 협정 이후 협력위원회가 단 한 차례밖에 열리 지 않았다. 농업 협력은 향후 식량안보와 밀접한 관련이 있기에 협력이 순조롭게 진행될 수 있도록 노력을 기울일 필요가 있다. 향후 자원확보 와 공급망 구축이 그 무엇보다 중요한 시기에 양국의 상황을 면밀하게 관찰하고 부족한 부분의 협력을 적극적으로 모색하는 노력이 매우 중요 하다.
