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 The continual improvement in the certification of coffee farms: a case study(Editora UFLA, 2018-10) Castro, Claúdio Vieira; Lira, Jean Marcel Sousa; Salgado, Eduardo Gomes; Beijo, Luiz AlbertoThe certification of agricultural products is considered a strategy that promotes sustainability and appreciation of product. In coffee production, the Certifica Minas Café is the only public coffee certification program in Brazil. However, over the years, many coffee farms that have this certification reduce their competence to meet the requirements, stabilizing at minimum levels of compliance, which allows maintaining the certificates, but does not promote continual improvement. Therefore, this study aimed to evaluate the effect of Certifica Minas Café certification on the improvement of sustainability over time on coffee farms. For this, a case study with two properties in the south of the state of Minas Gerais was carried out in which one of them quest to not achieve continuous improvement, while the other does. On the coffee farm of the first case was observed a reduction of number of requested fulfilled by the certification program over time. While coffee farm of the second case there was a reduction in investment and low concern to maintain the requirements established by the certification. Lastly, this paper hypothesizes that improvement of sustainability depends on understanding the benefits of certification in the long term and is related to a behaviour change by the certified farm.
