This study was conducted to search the origin of Nong Jung Shin Pyun ( 農政新編 ), a book of agricultural manual. This book was edited by An Jong-Soo who translated the agricultural manual of Japan and China, both were writted in Japanese. This book might be used not only as text book for agricultural workshop but as reference book for peasants.

This study aimed to explore companion planting to improve vegetable productivity on extensive green roofs through urban agriculture with limited substrate depth. From May to July 2021, the study conducted on the rooftop to evaluate the effects of marigold (Tagetes patula) planting ratio on the growth and pest control of cabbage (Brassica campestris). The experiment plot measured 1 m in width × 1 m in length × 0.25 m in height and 0.2 m in substrate depth. Fifteen plots were planted in varying proportions of cabbage and marigold for three repetitions per treatment: cabbage control (CC), 2:1(C2M1), 1:1(C1M1), 1:2(C1M2), and marigold control (MC). We found that companion planting marigolds with cabbage significantly increased cabbage growth and reduced pest infestation. The study revealed that C1M1, when cabbage and marigold have the same proportion, is an efficient companion planting ratio. Companion planting, in which non-crop vegetation manages pests and increases crop productivity, improves natural pest control and preserves biodiversity on rooftop urban agriculture.

This study aimed to evaluate the growth of Cichorium intybus, Brassica juncea, and Lactuca sativa at varying seed ratios, and to suggest an efficient management plan for sustainable indoor agriculture systems. It was treated with mixed sowing as follows: 30 chicory seeds (chicory alone: CC), 22 chicory seeds + 8 lettuce seeds (C3L1), 20 chicory seeds + 10 lettuce seeds (C2L1), 15 chicory seeds + 15 lettuce seeds (C1L1) as intraspecies, and 30 mustard seeds (mustard alone: MC), 22 mustard seeds + 8 lettuce seeds (M3L1), 20 mustard seeds + 10 lettuce seeds (M2L1), 15 mustard seeds + 15 lettuce seeds (M1L1) as interspecies. The study identified the competitive response in seed germination between Cichorium intybus and Lactuca sativa, and in the C3L1 experimental group, Lactuca sativa had the highest leaf length, root length, chlorophyll content, and fresh weight. Therefore, the higher the ratio of Cichorium intybus, the higher the growth and productivity of Lactuca sativa; however, higher the ratio of Lactuca sativa, the lower the growth of Cichorium intybus. Furthermore, the nitrogen and potassium content in the substrate was the highest in the C3L1 experimental grorp which had the highest seeding rate of the Cichorium intybus. Comparing the groups Brassica juncea and Lactuca sativa, the higher the seeding ratio of Lactuca sativa, the higher the growth and productivity of Brassica juncea. Therefore, a companion seeding of Brassica juncea and Lactuca sativa is beneficial; this could be effective in having a high seeding ratio of Lactuca sativa.

This study evaluated the growth, physiological responses and productivity based on the intercropping ratio of cherry tomato (Lycopersicon esculentum L.) with basil (Ocimum basilicum L.). on the rooftops to determine out the efficient ratio in urban agriculture. From April to September 2019, an experiment was conducted on the rooftop of Konkuk University Glocal Campus. Cherry tomato and basil were selected as companion plants for eco-friendly urban agriculture on the rooftops. Each plot was created with a width of 100 cm, length of 100 cm, and height of 25 cm. After installing drainage and waterproof layers from bottom to top, substrate was laid out with a height of 20 cm. Intercropping ratio was consisted of a single tomato plant (TC), 2:1 tomato to basil (T2B1), 1:1 tomato to basil (T1B1), 1:2 tomato to basil 2 (T1B2), and a single basil plant (BC), were conducted using a randomized complete plot design with five treatments and three replication (a total 15 plots). Measurements were divided into growth, physiological responses, and productivity parameters, and detailed items were investigated and analyzed by classifying them into plant height, leaf length, leaf width, number of leaves, root length, root collar caliper, chlorophyll contents, fresh weight, dry weight, number of fruit, fruit caliper, fruit weight, and sugar content. Comparative analyses of cherry tomato with basil plants by intercropping ratio, growth, physiological, and productivity responses are determined to be efficient when the ratio of cherry tomato to basil ratio is 2:1 or 1:1.

Soil conservation management is necessary for sustainable agriculture, in highland areas, and cover crops are one of the best soil conservation methods for slopes. In this study, we evaluated the effects of alfalfa cultivation on maize production, as well as soil conservation and quality. There was an outstanding soil conservation effect with alfalfa cultivation in the fallow and maize growing seasons. In particular, alfalfa cultivation reduced soil loss by up to 98% compared with bare field. It also increased the activities of soil microorganisms and the supply of organic matter. Maize production with alfalfa cultivation showed no significant differences in yield. In conclusion, alfalfa is an advantageous perennial cover crop in highland agricultural slope areas, which can have positive effects on soil quality and conservation, as well as maize production.

This study was conducted to analyze the factors influencing participation intention in urban agriculture. The theoretical foundations of the study were Theory of Planned Behavior (TPB) and Pine and Gilmore’s Experiencel Economy. The type of household composition was set as the moderating variable between these independent and dependent variables. In order to test the research model, hierarchical regression analysis was conducted on 439 effective respondents. The empirical analysis results are as follows. Educational experience factors, escapist experience factors, attitudes, subjective norm, and perceived behavioral control, which were set as independent variables to positive (+) influence participation intention in urban agriculture. In addition, the impact of their influence relationship was as follows : perceived behavioral control > attitudes > escapist experience factor > subjective norm > educational experience factor. On the other hand, as a result of analyzing the moderating effect according to the household composition, there was a significant difference in the effect of educational experiences, escapist experiences, and subjective norm on participation intention in urban agriculture. Significant results were not tested on the moderating effects between attitudes, perceived behavioral control, and participation intention in urban agriculture. Based on the results of this empirical analysis, academic and practical implications were presented.

Multi-criteria stock selection is a critical issue for effective investment since the improper stock investment might cause many problems affecting investors negatively. Investors need a range of financial indicators while they are choosing the optimal set of stocks to invest. This study aims to rank the stock of agriculture companies indexed on the Vietnam Stock Exchange Market. The data of 13 agriculture companies during the 2016-2019 periods was analyzed by analytical hierarchy process (AHP) integrated with grey relational analysis (GRA), multiobjective optimization ratio analysis (MOORA), and technique for order performance by similarity to ideal solution (TOPSIS). The AHP method is employed to determine the weights of the proposed financial ratios, and GRA, TOPSIS, and MOORA approaches are used to obtain final ranking. The results indicated that HSL is the top stock with the highest rank and GRA, MOORA, and TOPSIS rankings have strong correlation values between 0.78-1. The findings suggest that the integrated model could be implemented effectively to specific analysis of industries such as oil and gas, textiles, food, and electronics in future research. Further, other techniques like COPRAS, KEMIRA, and EDAS could be employed to evaluate the financial performance of other companies to solve investment problems.

The purpose of this study was to examine the intention of consumer acceptance of technology in agricultural production by applying the unified theory of acceptance and use of technology (UTAUT) to smart farm. In particular, this study analyzed the intention to accept the technology of agricultural students, farmers, start-up farmers, returning farmers, and returnees in the general manufacturing industry and high-tech industries, and in agricultural sectors corresponding to primary industries. The results showed that performance expectancy, social influence, facilitating conditions, IT development level, and reliability had a significant influence on the intention to use smart farm technology. However, effort expectancy and price value were rejected because no significant impact on use intention was tested. In addition, the influences of the variables showing their influence were reliability (β=.569) > IT development level (β=.252) > social influence (β=.235) > performance expectancy (β=.182) > facilitating conditions (β=.134).

This study argues that expanding the multifunctionality of agriculture (MFA) may mitigate existing agricultural problems. To do that this study redefines the concept and scope of the MFA and presents practical tasks to achieve it. Theorizing the MFA begins with the theory of sustainability and first identifies the link between sustainability and MFA. Later, considering the limitations of the existing sustainability theories, we examined where the false linkages leading to the destruction of environmental and social relations originated, and employed the (Re)productivity [(Re)produktivitat] theory in order to obtain alternatives. Research shows that welfare effects of the MFA on humans and the environment are not less than those derived from the agricultural products supplied to the real market, but the values are not recognized. The absence of proper care and compensation is the basis of agricultural problems in Korea. Therefore, this study acknowledges that the MFA is as much worthy as real agricultural production, and insists that appropriate compensation and care should be given to humans (farmers) and nature (agricultural ecosystem) in order to maintain and expand the MFA. In other words, a virtuous cycle between sustainability and the MFA means that the process spreads sustainable farming methods to expand the MFA, forms social consensus on it, and pays fair remuneration for agriculture from the public sector. Transition to such a virtuous cycle requires re-establishing the definition and scope of the MFA, implementing targeting policy, motivating policy targets, strengthening human capacity, and arranging maturity time.

Tropaeolum majus, with a high decorative and food demand for vertical greening systems, has been utilized to revitalize urban agriculture. The effects of number of non-woven fabrics in a non-water environment and the adaptability of T. majus to this system were investigated. Planting ground composition of the container-type wall vertical greening system was made using non-woven fabric in one, two, three, or four layers. The results showed that the soil water content remained the highest when the non-woven fabric comprised 4 sheets. The morphological properties showed more growth with the 4 sheets than with 1, 2, and 3 sheets. In terms of physiological characteristics, chlorophyll content was mostly high in the 4 sheets, while shoot fresh weight value was in the order of 3 sheets > 4 sheets > 2 sheets > 1 sheet, and root fresh weight value was in the order of 4 sheets > 2 sheets > 1 sheet > 3 sheets. The dry weight of the measured values in the shoot was in the order of 4 sheets > 3 sheets > 2 sheets > 1 sheet while no clear difference was found in the root of each treatment. The difference in the flowring characteristics was not different, but in evaluating the characteristics as a whole, the growth in the three layers of non-waven fabric was the best. In addition, the soil moisture content and the growth characteristics were statistically significant as a positive correlation between the groups. Thus, greater the non-woven fabric, the higher is the adaptability of T. majus to dry stress under soil water-free conditions by maintaining soil moisture content. This showed that it represented an effective alternative as a method of vertical greening system for lower maintenance urban agriculture.

The aim of our study was to provide a basic data for the development of a small greenhouse model suitable for urban farmers. The study analyzed installation inclination, positive and negative reasons for installation, location of installation, preferred crops in small greenhouses, plans for use of products, and expected effects by using small greenhouse. Positive opinion on small greenhouse installation was 80.4% of the survey respondents. The most positive reason for the installation of small greenhouses was fresh and safe food supply, and the negative reason was maintenance difficulties. The results obtained in our survey indicated that small greenhouses were more likely to be installed near the house, and urban farmers tended to grow organic leafy vegetables in soil. The expected benefits of small greenhouse operation were largely divided into ‘benefit for the improvement of the quality of life’ and ‘benefit for economic profits’, and expectation for the improvement of the quality of life was higher than economic benefit. As a result of the Likert 5-point scale analysis, ‘benefit for the improvement of the quality of life’ by using a small greenhouse was graded as high as 4.17∼4.60. On the other hand, the ‘benefit to economic profits’ was rated as low as 3.51∼4.14.

1980년대 이후 세계적 기상이변으로 인한 식량부족 위기설이 대두되며 이를 해결하기 위한 농업R&D 대응방안이 시급하다는 지적이 나왔다. 미래 산업혁명의 기반은 연결(connectivity)이다. 사람과 사물, 사물과 사물 사이의 연결에서 오는 데이터가 사물인터넷(IoT), 인공지능(AI), 가상현실(VR) 등 지능 정보 서비스로 연결(connectivity)되어 있다. 급변하는 산업화시대 농업은 디지털 산업과 바이오기술의 융합을 통해 자연환경을 제어할 수 있을 뿐만 아니라 개인 소비자 맞춤형 농산물을 생산할 수도 있다. 우리가 그동안 인식하고 있던 농업은 토양에서 농작물을 재배하고 수확하는 것으로서 생산량은 기술보다는 경지면적에 더 크게 좌우되는 산업이었다. 그러나 21세기 농업은 노동·토지·자본이라는 전통적인 농업 생산성 요소를 기술로 대체하게 된다는 의미로 해석 될 수 있으며 이러한 농업에서의 광고홍보 전략도 끊임없이 진화하고 있다. 광고는 현대의 핵심적인 커뮤니케이션 수단의 하나이다. 농업의 시장 환경이 불확실하고 과거처럼 생산만 하여도 끝없이 팔리던 시대는 끝났고, 해외 농산물의 수입 등으로 유동적인 시장에 대처하기 위해서는 끊임없이 새로운 아이디어를 창출하여 소비자들과 소통을 해야 한다. 과거 농업분야의 광고홍보포스터의 사례를 통해 진화과정을 분석하고, 미래 산업화시대의 ‘광고전략을 만들기 위한 조건’을 제안하고자 한다. 이를 통해 변화하는 한국 농업의 미래 키워드를 연구하고 전통적 농업과 스마트 기술의 결합으로 진화하는 광고홍보포스터의 방향을 제시하는 것이 본 연구의 목적이다.

Vertical farming systems offer many advantages in urban spaces. They have also been proposed as an engineering solution to increase the productivity per unit area of cultivated land by extending crop production in the vertical dimension. However, soil water retention is a major constraint affecting the plant environment. This study analyzed the effects of growth environment of Tropaeolum majus and Fragaria spp., on the vertical farming system, by using four different types of cover material types including sphagnum moss (Control), a shading net (S.N.), multi-layered fabric (M.L.F.), and non-woven fabric (N.W.F.). The volumetric soil moisture contents and plant characteristics were investigated from May to September 2014. Plant materials were individually cultivated in hanging baskets measuring 30×17×17 cm, filled with a mixture of soil and perlite, and placed at 1.5m height. Each treatment was performed in quadruplicate and consisted of five plants, amounting to a total of 20 plants. The analysis indicated that different covers were associated with multiple functions and soil water retention improvements may have a positive impact on the vertical farming system. The difference in soil water retention increased in the following order: M.L.F. > Control > N.W.F. > S.N.. Furthermore, the differences in plant height and survival rate increased in the following order: M.L.F. > Control > N.W.F. > S.N. Therefore, M.L.F yielded satisfactory good response for the vertical farming system of cover materials. Our results clearly demonstrate that vertical spaces represent an attractive alternative to urban farming and suggest that further increases in yield may be achieved via different cover materials in vertical farming using hanging baskets.
