Item Trends and findings in the rooting of conilon coffee: a bibliometric review(Universidade Federal de Santa Maria, 2025) Sallin, Valéria Pancieri; Lira, Jean Marcel Sousa; Falqueto, Antelmo Ralph; Arantes, Lúcio de Oliveira; Dousseau-Arantes, SaraThe structure of the root system of the conilon coffee tree has improved over the years through propagation, genetic, and agronomic studies in response to demands for improvements in plant development, production, and survival of the species. Scientific research plays an important role in generating technologies and the security of applications. However, there is a need to refine the content generated to analyze discoveries and trends on the subject. Therefore, the present study conduct a bibliometric review and analysis on the main contributions of relevant studies, researchers, organizations, and countries in academic research on the rooting of Coffea canephora in the Web of Science (WOS) database. Data from the WOS database published between 1982 and 2021 and systematized in the VOSviewer software showed a set of 92 articles, the majority of which originated in Brazil and France, with the main groups being the Brazilian Agricultural Research Corporation, the Federal University of Viçosa, and CIRAD. The study was divided into five areas: genetic diversity, asexual propagation, nematology, tolerance to water stress, and micropropagation. However, in the context of climate changes and its impact on the production and longevity of Brazilian coffee farming, research focused on the root system has increased significantly, integrating it into lines that explore and integrate topics such as climate risk, water management, drought tolerance, and drip irrigation, including reflections on the performance of coffee agronomy.Item IPR Alvorada – Dwarf Arabica coffee cultivar with high yield(Crop Breeding and Applied Biotechnology, 2024-09-25) Sera, Gustavo Hiroshi; Sera, Tumoru; Mariucci Junior, Valdir; Harumi, LucianaIPR Alvorada is a Coffea arabica cultivar with C. canephora introgression, developed from a cross between IAPAR 59 and Mundo Novo IAC 376-4.

The objective of this study was to select Arabica coffee accessions from the Minas Gerais Coffee Germplasm Collection grounded in agronomic traits. The productivity, quantified in bags per hectare, of 25 accessions was evaluated across four harvests, as was the percentage of maturation and floating beans. Genetic parameters were estimated for these attributes, aiming to glean insights into the potential for genetic gain and to facilitate decision-making in breeding practices. The REML/BLUP procedure was used to estimate variance components and predict random effects within the agronomic data. Genetic variability was observed among the studied accessions for productivity and the percentage of dried/pass fruits, indicating potential for genetic gain through selection within this group of accessions. There is potential for genetic breeding through selection, leading to subsequent enhancement in the means of the evaluated traits, notably in accessions MG0223 (Pacamara), MG0438 (Mundo Novo x S795 UFV 335-04), MG0194 (Caturra Amarelo Colombiano), MG0420 (Mundo Novo x S795 UFV 315-04), and MG0036 (Bourbon Amarelo). These results highlight the potential of these accessions to produce specialty coffees and their suitability for future breeding programs aimed at improving beans quality and productivity in Brazil.Item Sensory perception of coffee consumers as a function of different genotypes and extraction methods(Universidade Federal Rural de Pernambuco, 2024-09-30) Nadaleti, Denis Henrique Silva; Sousa, Maísa Mancini Matioli de; Ribeiro, Michele Nayara; Vilela, Diego Júnior Martins; Pereira, Dyanna Rangel; Carvalho, Gladyston RodriguesCoffee is one of the most consumed beverages in the world, with unique organoleptic characteristics of aroma and flavor, also varying according to the several extraction methods. Therefore, the objective of this study was to investigate whether the different Arabic coffee genotypes prepared by various extraction methods would influence amateur consumers’ perception of sensory and hedonic judgments of specialty coffee. A large-sample experiment (n = 270) was conducted in a coffee shop at the Universidade Federal de Lavras and participants were divided into three groups according to the evaluated genotypes (Bourbon Amarelo, Pacamara and Híbrido de Timor), who tasted four samples, varying to the extraction methods (‘Conventional Brewed’, Hario V60, French Press and Espresso). From the results obtained, it is possible to conclude that there is a change in the sensory perception of aromas and flavors of coffees in all genotypes studied in the four extraction methods, as well as in the acceptance and purchase intention by consumers.Item Soil physical, chemical and biological properties in Conilon coffee intercropping systems(Sociedade Brasileira de Ciência do Solo, 2024-04-08) Souza, Joabe Martins de; Pires, Fábio Ribeiro; Pezzopane, José Ricardo Macedo; Chagas, Kristhiano; Nascimento, Alex Favaro; Rodrigues, José de Oliveira; Czepak, Marcio Paulo; Nascimento, Adriel LimaShaded coffee systems may offer a series of benefits, however, studies on shaded cultivation of Conilon coffee crops are still scarce in the literature. This study aimed to evaluate the soil physical, chemical, and biological properties of two Conilon coffee intercropping systems from southeastern Brazil. Two commercial coffee crops – one shaded by macadamia trees and the other by green dwarf coconut trees – were evaluated according to three treatments: coffee plants in the inter-row of the tree species; coffee plants in the same row of the trees; and unshaded coffee. The experimental design was a completely randomized with four replicates. Coffee plants intercropped with macadamia trees, both intra- and inter-row, resulted in less soil compaction than unshaded systems. As for intercropping with green dwarf coconut trees, the unshaded system presented lower soil resistance to penetration. Differences in physical properties between treatments allow no inferences about intercropping systems influence on green coconut trees. Intercropped coffee improves soil chemical properties, resulting in greater soil fertility than unshaded systems, and showed greater soil organisms. These findings indicate that Conilon coffee-macadamia intercropped with tree species represents a promising alternative for sustainable soil management.Item Efecto de técnicas de agricultura ecológica en microorganismo del ciclo del nitrógeno en suelos bajo cultivo de café(Universidade Federal Rural de Pernambuco, 2023-12-29) Bernal, Johan Alexander Bonilla; Cifuentes, Andrés Felipe Calderón; Avellaneda-Torres, Lizeth ManuelaLa agricultura ecológica promueve un sistema interactivo para la sostenibilidad del suelo y los agroecosistemas, aprovechando y optimizando los recursos disponibles para mejorar la calidad del suelo cultivado. La presente investigación tuvo objetivo evaluar los cambios físicos, químicos y en los microorganismos del ciclo del nitrógeno del suelo tras la aplicación de técnicas de agricultura ecológica como humus líquido, humus sólido, microorganismos eficientes, biol, gallinaza, fosfitos, estimulo del policultivos y abonos verdes, en cafetales de diferentes edades. Para dicha evaluación se realizaron muestreos durante los meses cero, cuatro y diez en parcelas de cafetales de cero, dos y cuatro años de siembra. Se determinaron parámetros fisicoquímicos y abundancia de microorganismos asociados al ciclo del nitrógeno (amonificantes (AMO), proteolíticos (PRO), oxidantes de amonio (BOA), oxidantes de nitrito (BON) y desnitrificantes (DEN). Los resultados evidenciaron cambios estadísticamente significativos producto de la aplicación de las técnicas de agricultura ecológica en el contenido de carbono orgánico, nitrógeno y fósforo del suelo. Estas diferencias estadísticamente significativas se dieron en los diferentes meses evaluados y en el mes 10 en contraste con el mes cero de aplicación de las técnicas. No obstante, no se encontraron cambios estadísticamente significativos en la abundancia de los microorganismos del ciclo del nitrógeno. Se obtuvieron relaciones directas entre variables como P y %OC; pH y DEN; BON y AMO. Se puede concluir que si bien la aplicación de técnicas de agricultura orgánica mejora las propiedades físicas y químicas de los suelos, no existen diferencias estadísticamente significativas en la abundancia de microorganismos del ciclo del nitrógeno.Item Transferência de mudas clonais de café do sistema convencional para o sistema hidropônico modificado(Universidade Federal Rural de Pernambuco, 2023-08-15) Cunha, Samuel Henrique Braga da; Lima, Amador Eduardo de; Carvalho, Alex Mendonça de; Guimarães, Rubens José; Teramoto, Érico Tadao; Freitas, Ana Flávia deCloning plants by cuttings, mineral nutrition via modified hydroponics and the use of alternative substrates emerges as technological innovations for seedling production. The objective in this study was to evaluate the transfer of cuttings from the conventional system to the modified hydroponic system. The following variables were analyzed: seedling lenght; number of shoots; shoot lengnt; total leaf number; number of remaining leaves; leaf area; root area; stomatal conductance, density, and functionality; stomatal opening; root volume, area, length and diameter; leaf area ratio; specific leaf area and weight of specific leaf matter. For statistical analysis, a completely randomized design (CRD) with 5 treatments, six replications and ten plants per plot was used. From the results obtained, it is possible to conclude that: the rooting of Coffea arabica cuttings is not necessary in a conventional system, and it can be performed directly in a modified hydroponic system; an adaptation in the proposed modified hydroponics system with nebulization in the environment is necessary for rooting, for the obtention of a higher quality seedlingItem Efectividad de un prototipo seleccionador de café cerezo con reconocimiento de imágenes usando machine learning(Universidade Federal Rural de Pernambuco, 2023-03-14) Valles-Coral, Miguel Angel; Bernales-del-Aguila, Carlos Ivan; Benavides-Cuvas, Elmer; Cabanillas-Pardo, LeninLa producción de cafés especiales es el objetivo principal de los caficultores a nivel mundial y depende de la selección de granos óptimos; sin embargo, especialmente en Latinoamérica, son procesados de manera manual y está influenciado por la subjetividad.

Diante disso, o objetivo deste trabalho foi avaliar o efeito da adição de diferentes doses de calcário e gesso agrícola e seus efeitos nas características agronômicas do cafeeiro em dois experimentos com época distinta de implantação da cultura. O delineamento experimental foi em blocos casualizados, com quatro repetições em esquema fatorial 4 x 4, onde o primeiro fator foi constituído por doses crescentes de calcário e o segundo por doses crescente de gesso. O primeiro experimento foi conduzido no período do inverno - verão e o segundo experimento no período da primavera – outono. As variáveis analisadas foram altura de planta (AP), diâmetro do caule (DC), índice de área foliar (IAF), matéria seca foliar (MSF), matéria seca radicular (MSR) e comprimento radicular (CR). Ao analisar as médias dos experimentos se observou que no experimento I, a AP apresentou valores superiores a do experimento II, com acréscimo de 1,84 cm nessa variável. Para as demais variáveis DC, IAF, MSF e MSR no experimento II alcançaram um incremento superior em relação ao experimento I na ordem de 0,4 mm, 9,08 cm2, 1,54 g, 4,12 g respectivamente. As doses de calcário e gesso agrícola não proporcionaram alterações das variáveis agronômicas em ambas às épocas avaliadas, durante o período de seis meses após transplantio.
