Currently, the main technologies of various fourth industries are big data, the Internet of Things, artificial intelligence, blockchain, mixed reality (MR), and drones. In particular, "digital twin," which has recently become a global technological trend, is a concept of a virtual model that is expressed equally in physical objects and computers. By creating and simulating a Digital twin of software-virtualized assets instead of real physical assets, accurate information about the characteristics of real farming (current state, agricultural productivity, agricultural work scenarios, etc.) can be obtained. This study aims to streamline agricultural work through automatic water management, remote growth forecasting, drone control, and pest forecasting through the operation of an integrated control system by constructing digital twin data on the main production area of the nojinot industry and designing and building a smart farm complex. In addition, it aims to distribute digital environmental control agriculture in Korea that can reduce labor and improve crop productivity by minimizing environmental load through the use of appropriate amounts of fertilizers and pesticides through big data analysis. These open-field agricultural technologies can reduce labor through digital farming and cultivation management, optimize water use and prevent soil pollution in preparation for climate change, and quantitative growth management of open-field crops by securing digital data for the national cultivation environment. It is also a way to directly implement carbon-neutral RED++ activities by improving agricultural productivity. The analysis and prediction of growth status through the acquisition of the acquired high-precision and high-definition image-based crop growth data are very effective in digital farming work management. The Southern Crop Department of the National Institute of Food Science conducted research and development on various types of open-field agricultural smart farms such as underground point and underground drainage. In particular, from this year, commercialization is underway in earnest through the establishment of smart farm facilities and technology distribution for agricultural technology complexes across the country. In this study, we would like to describe the case of establishing the agricultural field that combines digital twin technology and open-field agricultural smart farm technology and future utilization plans.

딸기는 숙근성 초본이며 내한성이 강한 과채류로 노지면적은 계속 감소하여 1996년에 907 ha이나, 시설재배면적은 계속 증가하여 6236 ha를 나타내고 있다. 이와 같이 딸기는 이제 대부분의 생산량이 시설 내에서 생산되고 있다. 유럽과 일본 등에서 딸기의 양액 재배 면적은 급속히 증가하고 있는데 비해 국내에서의 딸기 양액재배 면적은 극히 적은 면적에 지나지 않지만, 앞으로 생산성과 품질의 증가가 기대되는 작물이기 때문에 재배 면적의 증가가 기대되는 채소작물 중 하나이다. (중략)

토경재배에서 작물의 수분소비 이론 모델식을 바탕으로 컴퓨터를 이용한 관수자동화 장치가 가능하나 노지재배 작물에 관한 것이 대부분이고 시설내 과채류 재배에 관해서는 연구가 미흡한 실정이며 또한 열악한 환경때문에 컴퓨터를 이용한 자동화장치는 실용가능성이 낮아 대부분 텐쇼메타와 석고블럭을 사용하여 토양수분을 측정하여 관수를 하고 있으나 토양수분의 상태에 따라 적용의 한계(토양수분장력 pf 2.8)가 다르므로 이 장치들의 정확한 작동을 기대하기는 어렵다. (중략)

시설재배토양은 노지에서와는 달리 비료의 용탈이 잘 이뤄지지 않기 때문에 작물에 따른 시비조절이 어렵다. 또한 대부분의 시설재배토양의 염류집적은 작물생산의 불안정한 요인으로 작용하고 있다. 최근 시설재배에서의 시비는 기비를 시용한 후에는 관비로 추비를 시용하고 있는데, 시비관리체계가 정립되어 있지 않아 농가마다 경험에 의존하여 시비관리되므로 비료를 과다하게 시용하기 쉽다. (중략)

하우스재배에서 수량이나 품질을 낮추는 주요한 원인 가운데에는 시설내에서 발생하는 병해나 생리장해가 있다. 우리나라는 아직 선진국과 같이 시설이 대형화되고 중장비화(重裝備化)되지는 않았지만 현재에도 하우스 재배가 전업화되고 단지화됨에 따라 자연 연작하지 않을 수 없게 되어 연작장해가 일어나고 있는 실정이다. 즉 하우스 재배에서는 단위면적당 수량을 높이기 위해서 밀식하는 경향인데 비해 하우스내는 고온이고 노지보다 시비량이나 관수량도 많아 비료성분인 염류(鹽類)가 쌓이고 토양 병원균도 많아지고 토양물리성이 나빠져 토양병해나 생리장해가 많이 발생하고 있다. 이 글에서는 하우스 작물의 연작장해의 원인과 실태조사 결과를 분석해보고 다음호에서는 그 대책에 대해 알아본다.

This study aims to determine the difference in profitability of Allium victorialis farming system between on-field and under-forest, and to propose several better ways for development of under-forest farming system of Allium victorialis. Survey was conducted 12 farmer in Gangwon, Chungnam, Jeonnam, Gyeongbuk to investigate production cost, management cost, input labors and so on. In this study, IRR, B/C ratio and NPV were used for profitability analysis. The result applied 25,000 won for under-forest farming system and 15,000 won for on-field farming system as unit price of sale showed IRR 36.2% and 54.2% respectively. The profitability of Allium victorialis from under-forest farm was not lower than other non timber forest products. And it will be possible to create high profitability such like that of Allium victorialis from on-field farm, providing the technical development for intensive farming is supported.

This study was carried out to determine the differences in the growth, grain yield, and seed quality of sesame plant according to seeding date between P,E. vinyl-house and outdoor cultures. Reproductive growth period in vinyl-house culture was shorter than in outdoor culture. Stem length and capsule setting length of sesame were much longer in vinyl-house culture than in outdoor culture. Also, number of capsules per plant and 1,000 grain weight in vinyl-house culture were higher, specially the grain yield was approximately 57% more than in outdoor culture. In vinyl house culture, sesame plants sown on June 8 had longer capsule setting length, more capsules per plant, higher 1,000 grain weight, and higher percent ripened grain at the upper part of the capsule settings than those sown in May 9. They also had higher 1,000 grain weight at the middle and lower part of the capsule settings compared to May 9 seeding. However, no difference in grain yield of in seeding dates was observed. In outdoor culture, sesame plants, which was sown on May 9, had more effective branch number and capsule number and plant compared to those sown on June 8. Though sesame plants sown on May 9 had lower percent ripened grain at the upper and middle part of the capsule settings and lower 1,000 grain weight, the seed yield was similar to those sown on June 8. No difference in chromaticity value $L^*$ of sesame seeds between two culture conditions was observed. The $a^*$ value was higher in vinyl-house culture than outdoor culture while $b^*$ value was higher in outdoor culture. Sesaminol triglucoside content of sesame seeds was higher in vinyl-house culture than in outdoor culture. On the other hand, the content of sesamin and sesamolin from sesame seeds in vinyl-house culture were lower than in outdoor culture.
