RESUMO O objetivo deste trabalho foi avaliar as características produtivas e a eficiência do uso da terra e da água em monocultivo e consórcio de rúcula com jambu sob regimes hídricos em dois ciclos de cultivo em região semiárida do Ceará. O delineamento experimental foi em blocos casualizados, em esquema de parcelas subdivididas, com 20 tratamentos e quatro repetições. As parcelas foram as irrigações, com 50, 75, 100, 125 e 150% de ETc. As subparcelas foram os sistemas consorciado e solteiro. Em cada ciclo foram avaliadas as características de crescimento das plantas e a eficiência do uso da água e da terra. Os maiores valores foram obtidos para número de folhas, altura, e massa fresca e seca das partes aéreas e raízes das plantas de rúcula quando consorciadas. Os melhores resultados para as variáveis de crescimento do jambu foram obtidos para as plantas cultivadas em monocultivo. Os valores de produtividade foram maiores no sistema solteiro; entretanto, os valores médios de eficiência do uso da terra no sistema consorciado foram de 1,23 e 1,28 em 2018 e 2019, respectivamente. Os melhores resultados foram obtidos com 75% ETc (DI75) para rúcula e irrigação total com 100% ETc (TI100) e irrigação em excesso com 125% ETc (EI125) para jambu. A eficiência do uso da água foi maior no sistema solteiro. Os índices de produtividade obtidos com o sistema consorciado rúcula-jambu e DI75 confirmam a maior eficiência biológica. Com base no exposto, conclui-se que rúcula e jambu são promissores para o consórcio em condições semiáridas.

ABSTRACT The objective of this study was to evaluate the production characteristics and the efficiency of land and water use in monoculture and intercropping of arugula with jambu under water regimes in two crop cycles in the semi-arid region of Ceará, Brazil. The experimental design was randomized blocks, in a split-plot scheme, with 20 treatments and four replicates. The plots were irrigation, corresponding to 50, 75, 100, 125 and 150% of ETc. The subplots were the intercropping and single systems. In each cycle, the growth characteristics of the plants and the efficiency of water and land use were evaluated. The highest values were obtained for number of leaves, height, and fresh and dry mass of aerial parts and roots of arugula plants when intercropped. The best results for the growth variables of jambu were obtained for plants grown in monoculture. The productivity values were higher in the single-cropping system; however, the average land use efficiency values in the intercropped system were 1.23 and 1.28 in 2018 and 2019, respectively. The best results were obtained with 75% ETc (DI75) for arugula and full irrigation with 100% ETc (TI100) and excess irrigation with 125% ETc (EI125) for jambu. Water use efficiency was higher in the single system. The productivity indices obtained with the arugula-jambu intercropped system and DI75 confirm the higher biological efficiency. Based on the above, it is concluded that arugula and jambu are promising for intercropping under semi-arid conditions.

ABSTRACT In Mexico, chickpea (Cicer arietinum L.) crop production is extensively limited and reduced by a disease known as wilt, caused by a complex of soil-borne plant pathogenic fungi. The objective of this study was to evaluate the antagonistic capacity of 31 isolates of Trichoderma spp. against the fungi Macrophomina phaseolina, Agroathelia rolfsii, Rhizoctonia solani, Neocosmospora falciformis, Fusarium languescens, F. nirenbergiae, and F. verticillioides. Trichoderma spp. isolates were obtained from rhizospheric soil and chickpea roots collected in the municipalities of Angostura and Salvador Alvarado, in Sinaloa, Mexico. Dual confrontations between the pathogen isolates and antagonistic agents were evaluated on PDA culture medium, using a completely randomized two-factor experimental design with three replicates. The recorded variable was the percentage of inhibition of radial mycelial growth. Of the 31 Trichoderma isolates evaluated, 22 induced > 55% inhibition of the plant pathogens; meanwhile, 7 Trichoderma isolates showed the highest antagonistic effect on each of the plant pathogens, causing > 59% inhibition. These 7 Trichoderma isolates were identified through multilocus phylogenetic analysis using internal transcribed spacer (ITS), EF-1ɑ, and rpb2 sequences, distinguishing 5 isolates as T. afroharzianum and 2 isolates as T. afarasin. These Trichoderma spp. isolates represent a biological control alternative against the complex of fungi causing chickpea wilt in Sinaloa.

Abstract Expansion of avocado production areas in Colombia has led to an increased demand for plant propagation material. However, this expansion has exacerbated phytosanitary challenges, particularly root rot disease mainly associated with Phytophthora spp. Therefore, this study aimed to identify Phytophthora species associated with root rot in avocado seedlings within nurseries. Avocado plants exhibiting wilting symptoms were collected from nurseries in the departments of Quindío, Risaralda, and Valle del Cauca (Colombia). Segments of diseased roots were selected, cut, and surface-disinfected, before being planted on Potato Dextrose Agar (PDA) supplemented with antibiotics and fungicides. Microorganism identification was conducted using taxonomic keys and confirmed by molecular techniques employing the identification based on phylogenetic hypothesis, using ITS1-5.8s-ITS2 region encoding for rRNA. Isolates obtained from necrotic avocado roots were identified as P. cinnamomi and P. heveae. The pathogenicity of the isolates was confirmed in avocado seedlings through inoculation, resulting in symptom reproduction. Consequently, this study identified P. cinnamomi and P. heveae as causal agents of root rot in avocado during the nursery stage.

Resumo Este artigo discute o desenvolvimento, ao longo do século 19, da tecnologia de produção em massa nos Estados Unidos. Assim como o computador e aviação espacial, essa tecnologia surgiu de um esforço liderado pelo estado para promover o progresso técnico na produção de armas e defesa, dando origem ao que era conhecido no século 19 como o “Sistema Americano de Manufaturas”. Embora as raízes desse sistema na política militar-industrial estejam bem estabelecidas, economistas continuam a sugerir que o progresso técnico na América neste período foi impulsionado por forças de mercado, liderado por empreendedores interessados em obter patentes e reduzir custos de produção. Oferecemos uma perspectiva diferente, com base em extensa pesquisa histórica já existente sobre este tópico. Discutimos as origens da tecnologia de peças intercambiáveis na Europa, seu desenvolvimento inicial nos Estados Unidos e sua difusão para a fabricação de bens de consumo após 1850. Também refletimos sobre as razões do interesse do Departamento de Guerra dos Estados Unidos nessa tecnologia após 1800.

Abstract This article discusses the development of mass production technology in the United States. Like spaceflight and the computer, this technology grew out of a state-led effort to promote technical progress in weapons and defense production, giving rise to what was known in the 19th century as the “American System of manufactures”. Though the roots of this system in military-industrial policy are well-established, economists continue to suggest that technical progress in 19th-century America was a market-driven affair, led by entrepreneurs eager to reduce production costs and obtain patents. We offer a different perspective, based on extensive historical research on this topic. We discuss the origins of interchangeable parts technology in Europe, its early development in the United States, and its diffusion to consumer goods manufacturing after 1850. We also reflect on the reasons for the United States War Department’s interest in this technology after 1800.

ABSTRACT One of the main phytosanitary problems in major crops are phytonematodes, which are characterised as difficult to control. In view of this, biocontrol, through the use of biological agents, has become a driving force in controlling these pathogens. The aim of this study was to evaluate the compatibility of microorganisms, and detect the possibility of antagonistic effects, influence on growth, or synergistic action when microorganisms are jointly applied to crops. Microbiological analyses were carried out to observe the interaction of the fungus Trichoderma asperellum with the bacteria Bacillus subtilis and Bacillus methylotrophicus. It was found that the interaction between the genera Bacillus and Trichoderma did not promote any increase in the fresh or dry weight of the roots or shoots of the soya plants; however, based on the results of the microbiological analysis of the fungi and bacteria, the interaction was found to be promising, particularly in the evaluation carried out on the seventh day. Considering the number of viable spores, the interaction between B. subtilis + T. asperellum showed better results than B. methylotrophicus + T. asperellum. The Interaction between the genera Bacillus and Trichoderma showed the potential for joint use in the biological control of the soya bean.

ABSTRACT The early seedling stage is one of the most vulnerable and critical growth stages in the plant life cycle and determines the final plant stand and yield. Corn hybrids have distinct degrees of drought tolerance, and exploiting this characteristic is important to enhance agricultural production in many tropical regions of the world. Fourteen corn hybrids commonly grown in the central-western region of Brazil, in Cassilândia, Mato Grosso do Sul, were assessed for drought tolerance during the early plant growth stage. Plants were grown in the Plant Ecophysiology Laboratory under non-stressful (control) and stressful (moderate drought) conditions for 28 days. Drought stress was induced with an -0.30 MPa iso-osmotic solution prepared with polyethylene glycol (PEG-6000). The emergence rate, seedling length, and seedling dry matter were measured, and then drought tolerance indexes were calculated. Our results showed that root length is an important morphological trait for plant adaptation to drought stress conditions. Therefore, plant breeding programs should select corn genotypes with longer roots to develop commercial hybrids with superior performance under limited soil water availability. The corn hybrids FS 575 PWU, GNZ 7757 VIP3, LG 36745 PRO4, and MG 545 PWU have greater tolerance to drought stress and are the most suitable genotypes to be grown in conditions of low soil water availability. The AG 8088 PRO2 corn hybrid has greater susceptibility to drought stress and should not be recommended for cultivation in conditions of reduced soil water availability.

ABSTRACT The search for cropping systems that aim to have the best area use, optimize production, and guarantee financial profitability to the producer and their establishment in the field are challenges of modern research. Thus, the objective of this study was to evaluate the productive and monetary viability of intercropping radish and coriander fertilized with equitable amounts of hairy woodrose and roostertree biomass from the Caatinga ecosystem at different coriander population densities in two cropping seasons. The experimental design used was randomized blocks, with treatments arranged in a 4 × 4 factorial scheme with four replications. The first factor was constituted by four equitable amounts of hairy woodrose and roostertree biomass (20, 35, 50 and 65 t ha-1 on a dry basis), and the second factor was constituted by coriander population densities (40, 60, 80 and 100% of the recommended density for monocropping, RDM). The greatest agronomic and monetary advantages of intercropping radish with coriander were obtained with a land equivalent coefficient and a monetary equivalence ratio of 0.42 and 0.76, respectively, in the amounts of hairy woodrose and roostertree biomass of 20 and 39 t ha-1 added to the soil, in the coriander population density of 100% of the RDM. The coriander green mass yield and commercial productivity of radish roots optimized in the intercropping were 1.25 and 14.90 t ha-1 when fertilized with 65 t ha-1 of green manures biomass in the coriander population density of 100% RDM.

Abstract In the face of the expansion of studies on race and racism in the area of Science, Technology, and Society (STS), in addition to the theme’s relevance for antiracist activism, this work proposes an intervention and a contribution to this field of study reconstructing its theoretical and methodological roots. Without intending to exhaust the available research on this subject, the article emphasizes the anthropological and sociological ramifications within STS studies on race. It then demonstrates its roots in Frantz Fanon’s work. Finally, it suggests that Fanon’s approach to the intersection of racism and technology, grounded in the context of the anti-colonial struggle, can be reworked vis-à-vis the transformations presented by the technical relations of the digital world. As a critical synthesis, the study proposes new dialogues with the Philosophy of Technology, especially in light of the renewed interest in Gilbert Simondon’s work, offering opportunities for exploration and reflection.

Resumo Diante do crescimento nos últimos anos dos estudos sobre raça e racismo na área de Ciência, Tecnologia e Sociedade (CTS), além da relevância do tema para o ativismo antirracista, este trabalho visa intervir e contribuir com o campo reconstruindo suas filiações teóricas e metodológicas. Sem pretender exaurir as pesquisas disponíveis nesse recorte, enfatizamos as ramificações antropológicas e sociológicas nos estudos em CTS sobre raça. A partir disso, demonstramos suas matrizes na obra de Frantz Fanon. Por fim, sugerimos que a abordagem fanoniana da intersecção entre raça e tecnologia, fundada no contexto histórico das lutas anticoloniais, pode ser reelaborada diante das transformações apresentadas pelas relações técnicas do digital. Como síntese deste estudo, propomos que novos diálogos com a Filosofia da Técnica, em especial pelo renovado interesse na obra de Gilbert Simondon, oferecem oportunidades de trabalho e reflexão.

Three undescribed non-cyanogenic cyanoglycosides, designated as trichotomoside A (1), B (2), and C (3) along with three known ones (4-6) were isolated from the roots of Cordia trichotoma. In addition, miscellaneous compounds such as acid (1’R,3’S,5’R,8’S,2Z,4E)-dihydrophaseic 3’-O-β-D-glycopyranoside (7), N-(2E)-3-[(2S,3R)-2-(4-hydroxy-3-methoxyphenyl)-3-(hydroxymethyl)-7-methoxy-2,3-dihydro-1-benzofuran5-yl]acryloylglycine (8), syringaldehyde (9), scoparone (10), 12,16-epoxyglobiferin (11), α-cadinol (12), trichotomol (13), and 1-(3’-methoxypropanoyl)-2,4,5-trimethoxybenzene (14) were also isolated. The structures of all compounds were elucidated by an extensive analysis of spectroscopic data (infrared (IR), nuclear magnetic resonance (NMR), and high-resolution electrospray ionization mass spectrometry (HRESIMS)). The non-cyanogenic cyanoglycosides (1-6) were screened for their α-glucosidase inhibitory activities. None of the compounds exhibited antioxidant or xanthine oxidase activity. Compound 3 exhibited considerable inhibitory ability on α-glucosidase, showing a halfmaximal inhibitory concentration (IC50) = 646 ± 69 μmol L-1 close to the standard acarbose (IC50 = 521 ± 23 μmol L-1), demonstrating its promising antidiabetic action.

Korea has seen remarkable development into a key worldwide missionary force since the advent of Christianity in the late 19th century. Building upon this context, the objective of this article is to explore the historical and practical consequences of the increase in Korean Christian overseas missionary endeavours and their relationship with politics. The article emphasises the pivotal significance of political elements in the transition from quantitative to qualitative transformations in Korean Christian missionary movements. For this purpose, the study takes a political science approach, methodically examines the historical relationship between Korean Christian foreign missionary activities and politics, and demonstrates how Korean Christianity has evolved from a key influence in the national movement to a significant participant in contemporary politics, encompassing both international and domestic politics. Given the changing political landscape, the overseas missionary efforts of Korean Christianity have emerged as a crucial element of the country's soft power, serving to protect national interests and propagate its religious beliefs. CONTRIBUTION: This article explores South Korean Christian missions' historical and political evolution, from nationalist roots to global influencers. It highlights their role in South Korea's soft power strategy, shaping domestic policies and global perceptions. Moreover, it sheds light on Asia, especially Korea, becoming a pivotal hub for Christian missionary endeavours, reflecting a global shift in missionary focus.

ABSTRACT Plants require iron (Fe) and copper (Cu) at low concentrations for metabolic functions; however, excess soil Fe and Cu can cause toxicity and affect plant development. The objective of this study was to assess the effects of soil Cu and Fe concentrations on seedling emergence, as well as on the metabolism of the main reserve compounds and the biomass in roots, stems, leaves, and cotyledons of Canavalia ensiformis. A greenhouse experiment was conducted in a completely randomized design; the Cu and Fe treatments in the soil were: (control, 50, 150, 250 and 350 mg dm-3) over a period of 10 days. Seedling emergence was not affected by the evaluated treatments; however, the results showed an increase in the emergence speed index (EVI) for the Fe treatment at a dose of 150 mg dm-3 of soil compared to 350 mg dm-3 of soil. Treatment with Cu at a dose of 350 mg dm-3 of soil reduced root length. Cu treatments reduced root dry mass. Fe treatments affected the content of soluble amino acids in the stems, leaves and cotyledons, as well as the total soluble proteins in the cotyledons and the carbohydrate content in the leaves. Cu treatments increased protein and carbohydrate content in leaves and starch content in cotyledons. High concentrations of Cu and Fe modify the production of nitrogenous compounds in the plant and reduce root biomass.

RESUMO As plantas necessitam de ferro (Fe) e cobre (Cu) em baixas concentrações para realizar funções metabólicas. Porém, o excesso de Fe e Cu no solo pode causar toxicidade e afetar o desenvolvimento das plantas. O objetivo desse estudo foi avaliar os efeitos das concentrações de Cu e Fe no solo na emergência das plântulas, bem como no metabolismo dos principais compostos de reserva e na biomassa de raízes, caules, folhas e cotilédones de Canavalia ensiformis. O experimento foi conduzido em casa de vegetação, em delineamento inteiramente casualizado; os tratamentos de Cu e Fe no solo foram: (controle, 50, 150, 250 e 350 mg dm-3) durante um período de 10 dias. A emergência das plântulas não foi afetada pelos tratamentos avaliados; entretanto, os resultados mostraram aumento do índice de velocidade de emergência (EVI) para o tratamento com Fe na dose de 150 mg dm-3 de solo em comparação com 350 mg dm-3 de solo. O tratamento com Cu na dose de 350 mg dm-3 de solo reduziu o comprimento das raízes. Os tratamentos com Cu reduziram a massa seca das raízes. Os tratamentos com Fe afetaram o conteúdo de aminoácidos solúveis nos caules, folhas e cotilédones, bem como as proteínas solúveis totais nos cotilédones e o conteúdo de carboidrato nas folhas. Os tratamentos com Cu aumentaram os teores de proteínas e carboidratos nas folhas e o teor de amido nos cotilédones. Altas concentrações de Cu e Fe modificam a produção de compostos nitrogenados na planta e diminuem a biomassa radicular.

ABSTRACT The present study investigated the impact of different concentrations of Trichoderma harzianum on the growth variables of tomato plants infected with both root-knot nematodes (Meloidogyne incognita) and the bacterial wilt pathogen (Ralstonia solanacearum). Application of T. harzianum significantly improved growth variables such as shoot and root lengths and shoot weight (p 0.001), with the highest growth observed at the concentration of 1×104 spores/mL. Lower concentrations (8×103 and 2×103 spores/mL) also enhanced growth, but to a lesser extent. Notably, root weight decreased, indicating reduced gall formation, a positive outcome against nematode infestation. The study revealed that T. harzianum significantly reduced the number of galls, eggmasses, and nematode reproduction factors (p 0.001). The highest concentration (1×104 spores/mL) was most effective, followed by 8×103 spores/mL, demonstrating a dose-responsive reduction in these parameters. Regression analysis showed positive correlations between decreased gall numbers and increased shoot and root lengths and weights, as well as between reduced eggmasses and improved growth variables. Regarding disease severity, increasing concentrations of T. harzianum notably decreased the severity of both root-knot nematodes and bacterial wilt compared to the control. The control treatment exhibited a 72.5% severity, whereas treatments with T. harzianum reduced severity to 51–55.5%, and the highest concentration reduced it to 2.5%. This trend was consistent for bacterial wilt severity. The results indicate that T. harzianum effectively colonizes tomato roots, inhibiting pathogen entry and reducing disease severity more effectively at higher concentrations. rootknot knot Meloidogyne incognita Ralstonia solanacearum. solanacearum . solanacearum) T p 0.001, 0001 0.001 , 0 001 0.001) 1104 1 104 1×10 sporesmL spores mL spores/mL 8103 8 103 (8×10 2103 2 2×10 extent Notably formation infestation galls 0.001.

This study describes the chemical composition and biological activities of extracts and compounds obtained from the roots of Bowdichia virgilioides (Fabaceae). A mixture of very long-chain free fatty acids (VLFAs) and pure compounds, namely isocordoin, cordoin, lupeol, lupenone, β-sitosterol, stigmasterol, and sitostenone, were isolated from the soluble fraction of the methanol extract by using sequential column chromatography procedures. The molecular structures of the compounds were determined using infrared (IR), nuclear magnetic resonance (NMR), and mass spectrometry (MS) techniques. Notably, this is the first report of the occurrence of both chalcones within this plant genus. Besides, the VLFAs were identified by electrospray ionization mass spectrometry (ESIMS) and the presence of these compounds in roots is suggested to be an adaptive response to environmental stress, which exhibited moderate antioxidant properties when tested against the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and in the β-carotene/linolenic acid auto-oxidation assay. However, the MeOH soluble fraction demonstrated significant toxicity in the brine shrimp lethality assay. Fabaceae. Fabaceae .

RESUMO: A batata-doce é uma cultura importante para a segurança alimentar com mercado mundial em ascensão. Com base nas alterações fisiológicas das plantas em resposta às condições climáticas e à fertilização, este estudo avaliou os efeitos da época de cultivo (período chuvoso e seco) e de doses de P2O5 (0, 50, 100, 200 e 400 kg ha-1) na produtividade total e por classes comerciais, bem como, a composição química das raízes de armazenamento de duas cultivares de batata-doce. A produtividade de raízes tuberosas foi maior na estação chuvosa. As doses ótimas agronômica e econômica foram de 128 e 95 kg ha-1 de P2O5 para a cultivar Canadense. A cultivar Uruguaiana não respondeu a adubação fosfatada, mas suas raízes tiveram maiores teores de matéria seca, lipídios, fibras, açúcares totais e redutores e amido. O cultivo de batata-doce no período chuvoso com doses de até 100 kg ha-1 de P2O5 aumenta a produtividade de raízes em classes de maior valor econômico e com maiores teores de carboidratos. Estes resultados ajudam os produtores a planejarem o plantio e a colheita da batata-doce ao longo do ano e contribui para a gestão da aplicação de fertilizantes fosfatados.

ABSTRACT: Sweet potato is an important food security crop, and the world market for this root is on the rise. Based on the physiological changes in plants in response to climatic conditions and fertilization, this study evaluated the effects of the growing season (rainy and dry season) and P2O5 doses (0, 50, 100, 200 and 400 kg ha-1) on total yield, marketable classes yields, as well as chemical composition of storage roots of two sweet potato cultivars. The storage roots yield was greater in the rainy season. The optimum agronomic and economic doses were 128 and 95 kg ha-1 P2O5 for the cultivar Canadense. Cultivar Uruguaiana did not respond to phosphate fertilization, but its storage roots had higher contents of dry matter, lipids, fibers, total and reducing sugars, and starch. Sweet potato cultivation in the rainy season with doses up to 100 kg ha-1 P2O5 increase root yield in marketable size classes in higher economic value and with higher carbohydrate contents. The results can help producers schedule the planting and harvesting of sweet potatoes throughout the year and contribute to the seasonal management of phosphate fertilizer application.

The genus Trichilia, belonging to the Meliaceae family, comprises ca. 102 species, some of which have been the subject of phytochemical studies. Compounds of different classes with cytotoxic, antimicrobial, and antioxidant activities were isolated from Thichilia. Trichilia pseudostipularis, a native species, is distributed along the entire Brazilian coast, from southern Santa Catarina to Bahia. Due to the inexistence of previous chemical studies, their wood and roots were investigated. Compounds 3,4-dihydro-4-isopropyl-6-methylnaphthalen-1(2H)-one (1), 3,4-dihydro-7-hydroxy-4-isopropyl-6-methylnaphthalen-1(2H)-one (2), and pseudostipulariol (3) were isolated from wood, while the lactone derivate rel-(2S,3S,4R)-3-hydroxy-4-methyl-2-(13”-phenyl-l’-n-tridecyl)-butanolide (4) was isolated from the roots.
