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.

Porém, as propriedades familiares são caracterizadas por serem conduzidas pelo núcleo familiar e com pouco auxí¬lio tecnológico, podendo tornar sua continuidade incerta para as gerações futuras. Objetivou-se abordar o processo de sucessão entre gerações de cafeicultores dentro dos contextos culturais, econômicos e sociais, dando ênfase no papel da mulher no processo de hereditariedade da cultura agrí-cola aos filhos. No presente estudo, foram analisados 146 questionários aplicados às mulheres das propriedades rurais da região das Matas de Minas, abordando sua participação no processo de sucessão.Foram utilizadas análises estatí¬sticas descritivas para discussão dos resultados. Foi possí¬vel observar que as mulheres entrevistadas participam do processo de sucessão da atividade cafeeira. Porém, não existem estratégias para a realização do processo de sucessão, bem como critérios definidos para a escolha dos herdeiros. Existe a tendência de a cafeicultura possuir a tradição das famí¬lias em trabalhar nesse setor, podendo influenciar os responsáveis a motivarem seus possí¬veis herdeiros a permanecerem nessa atividade. Conclui-se que é necessário haver maior preocupação e planejamento por parte das famí¬lias envolvidas na cafeicultura para que os futuros herdeiros se sintam engajados e motivados a continuar nesse setor. As mulheres, apesar de praticarem o processo de sucessão no meio rural, precisam ter consciência da importância do papel que exercem tanto dentro da famí¬lia quanto no processo de preparação dos possí¬veis sucessores.Item Domínio Tecnológico distribuído: evidências da agroindústria de café brasileira(Universidade de Taubaté - UNITAU, 2019-05-30) Gonzalez, Rafael KuramotoEste artigo diz respeito ao desenvolvimento tecnológico e inovação numa indústria intensiva em processamento de recursos naturais (IIPRN) no contexto brasileiro. É objetivo da pesquisa explorar como o domí¬nio tecnológico distribuí¬do auxiliou no desenvolvimento tecnológico de uma agroindústria de café solúvel nas décadas de 1970 a 2010. A literatura de inovação já apresenta uma considerável compreensão acerca do processo desagregado e distribuí¬do de construção de domí¬nio tecnológico entre parceiros em empresas de economias emergentes. Contudo, pouco se explorou como esse domí¬nio distribuí¬do se modifica e/ou evolui ao longo do tempo. Ademais, alguns estudos encapsulam as IIPRN com limitada oportunidade de criação de conhecimento tecnológico, desenvolvimento de atividades de inovação e externalidades positivas para o desenvolvimento econômico. Entretanto, pouco se investigou o processo de industrialização e de desenvolvimento tecnológico em IIPRN, com raras exceções. Baseando-se em evidências da agroindústria do café solúvel, por meio de um desenho qualitativo com base em uma estratégia de estudo de caso em ní¬vel de empresa, e com cobertura de longo prazo, esta pesquisa encontrou: (a) Heterogeneidade nos tipos de parceiro acessados e formação do domí¬nio tecnológico distribuí¬do entre as diferentes funções tecnológicas; (b) Heterogeneidade nos tipos de parceiro e formação do domí¬nio tecnológico distribuí¬do ao longo do tempo. Ademais, a pesquisa concluiu que as IIPRN podem oferecer oportunidades para inovações significativas, serem protagonistas na criação tecnologias e participarem ativamente de redes complexas de conhecimento tecnológico.Item Caracterização de germoplasma de Coffea arabica L. com base em características agronômicas(Universidade Federal Rural de Pernambuco, 2024-10-01) Silva, Maria Gabriela Pereira e; Abrahão, Juliana Costa de Rezende; Nadaleti, Denis Henrique Silva; Pereira, Antônio Alves; Fassio, Larissa de Oliveira; Botelho, Cesar EliasGenetic resources embody the reservoir of essential natural variability for cultivated species breeding programs. 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 Doses de gesso em cafeeiro: influência nos teores de cálcio, magnésio, potássio e ph na solução de um latossolo vermelho distrófico(Sociedade Brasileira de Ciência do Solo, 2013-08-24) Ramos, Bárbara Zini; Toledo, João Paulo Vaz Floriano; Lima, José Maria de; Serafim, Milson Evaldo; Bastos, Ana Rosa Ribeiro; Guimarães, Paulo Tácito Gontijo; Coscione, Aline RenéeUnbalanced amounts of Ca2+, Mg2+ and K+ in soils as a consequence of high gypsum applications can be due to the relationship in size (ionic radius) and charge density (charge/ ionic radius) of each ionic species. The higher the ionic strength, the stronger is the bonding of these cations with the opposite charge ions such as OH- , SO4 -2. Thus, excessive gypsum applications, disregarding the charge balance of the soil colloidal system, the ionic balance of the solution, and the CEC, can result in significant leaching of these nutrients throughout the soil profile. The aim of this study was to evaluate the effect of high gypsum rates (0, 7, and 56 t ha-1) on the pH and Ca2+, Mg2+, and K+ contents in aqueous soil extracts of a dystrophic Red Latosol with coffee. The soil was sampled in the coffee rows in the following depths: 0.15- 0.25; 0.35-0.45; 0.75-0.85; 1.15-1.25, and 2.35-2.45 m, 16 months after gypsum application. The experiment consisted of four treatments: G-0 – 2 t ha-1 of gypsum was applied in total área during soil preparation, with brachiaria between coffee rows; G-7 - same as in G-0 plus 7.0 t ha-1 of gypsum applied to the coffee rows; G-56 – same as in G-0 plus 56 t ha-1 of gypsum applied to the coffee rows; and CV-7 - same as in G-7 but without brachiaria between the coffee rows. The experiments were conducted in triplicate, in a randomized block design. After 16 months, there was a reduction of the pH of the soil solution in the layers 0.15-0.25, 0.35-0.45, and 0.75-0.85 m. Gypsum improved the root environment in deeper layers, increasing Mg2+ and Ca2+ concentrations in the soil solution, but reduced K+ below 0.85 m. The amounts of exchangeable Ca2+ and Mg2+ found in the soil solution were above the critical level while exchangeable K+ was within the range indicated for the crop.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.
