ABSTRACT: A 4-month-old male Himalayan cat presented with clinical signs of acute lethargy and motor incoordination after being treated with amitraz for parasite control. On clinical examination, the patient was lethargic and ataxic with severe pulicosis, hypothermia, pale mucous membranes, bradycardia, weak femoral pulses, hyperglycemia, and bilateral mydriasis. Blood tests revealed non-regenerative hypochromic microcytic anemia. Serum alanine levels were elevated tenfold. The patient received supportive treatment with atipamezole (an α2-adrenergic antagonist) at a dose of 0.1 mg/kg intramuscularly. After 24 h of hospitalization and constant monitoring, the patient recovered and was discharged. The published literature showed that the active ingredient amitraz is effective in the treatment of some parasitic diseases in cats, such as scabies and demodicosis; therefore, it is still used for this purpose. Given the small therapeutic margin of this insecticide, veterinarians should caution owners about its potential toxicity. This report emphasized the significance of amitraz intoxication in feline species and the success of the treatment, which should be initiated in the first hour after intoxication.

RESUMO: Um gato da raça Himalaia, macho, com quatro meses de idade, apresentou sinais clínicos de letargia aguda e incoordenação motora após ser medicado com amitraz para controle de parasitas. No exame clínico, o paciente se apresentava letárgico e atáxico, com pulicose grave, hipotermia, mucosaspálidas, bradicardia, pulso femoral fraco, hiperglicemia e midríase bilateral. O exame de sangue revelou anemia microcítica hipocrômica não regenerativa. Os níveis séricos de ALT estavam 10x elevados. O paciente recebeu tratamento de suporte e administração de atipamezol (antagonista α2-adrenérgico) na dose de 0,1 mg/kg por via intramuscular. Após 24 horas de internação e acompanhamento constante, o paciente se recuperou e recebeu alta. Dados publicados na literatura demonstram que o princípio ativo amitraz é eficaz no tratamento de algumas doenças parasitárias em gatos como sarna e demodicose e, portanto, ainda é utilizado para esta finalidade. Dada a pequena margem terapêutica deste inseticida, os veterinários devem informar os proprietários sobre o seu potencial de toxicidade. O objetivo deste relato é enfatizar a importância da intoxicação por amitraz na espécie felina e o sucesso do tratamento, que deve ocorrer nas primeiras horas após a intoxicação.

ABSTRACT: In Brazil, the optimal dose of phosphorus in the cultivation of yerba mate (Ilex paraguariensis St. Hil.) clones has yet to be defined. This study verified the productivity of yerba mate clones in response to the application of P doses and determined the critical level of the nutrient in soil and yerba mate leaves. The experiment was developed in Itaiópolis-SC, in humic cambisol, from 2013 to 2020. Five doses of the nutrient were evaluated in two clones (BRS-BLD Aupaba and F2) of yerba mate. Fertility was defined by planting/post-planting (0, 2.3; 4.5; 6.8, and 9.0 g plant-1), canopy formation 1 (0, 10, 20, 30, 40, and 50 g plant-1), canopy formation 2 (0, 15, 30, 45, and 60 g plant-1), and production (0, 16.7; 33.3; 50.0; 66.7 kg ha-1). Harvests took place between July 2015 and January 2020, at 18-month intervals. The productivity of leaves, fine branches, and thick branches was evaluated. In the 2020 harvest, soil and leaf samples were collected to determine the critical level of P. The productivity of clone components increased with phosphate fertilization in all evaluated harvests. The critical levels of P for clones, Aupaba and F2, were 5.2 and 6.3 mg dm-3 in soil and 1.03 and 1.11 g kg-1 in leaves, respectively. Yerba mate is demanding of P, expressing maximum productivity in the planting phase, canopy formation 1 and 2, and production when doses of 5, 25, 40 g plant-1, and 35 kg ha-1 of P2O5 are applied, respectively.

RESUMO: No Brasil, a dose de fósforo no cultivo de clones de erva-mate ainda não está definida. O objetivo do estudo foi verificar a produtividade de clones de erva-mate em resposta a aplicação de doses de P e determinar o nível crítico do nutriente no solo e folhas de erva-mate. O experimento foi implantado em Itaiópolis-SC, em Cambissolo Húmico, em 2013. Foram avaliadas cinco doses do nutriente em dois clones (BRS-BLD Aupaba e F2) de erva-mate. As adubações foram definidas como de plantio/pós-plantio (0, 2,3; 4,5; 6,8 e 9,0 g planta-1), formação de copa 1 (0, 10, 20, 30, 40 e 50 g planta-1), formação de copa 2 (0, 15, 30, 45 e 60 g planta-1) e produção (0, 16,7; 33,3; 50,0; 66,7 kg ha-1). As colheitas ocorreram entre julho de 2015 e janeiro de 2020, com intervalos de 18 meses. Avaliou-se produtividade de folhas, galhos finos e galhos grossos. Na safra de 2020, foram coletadas amostras de solo e folhas para determinação do nível crítico de P. A produtividade dos componentes dos clones aumentou com a adubação fosfatada em todas as safras avaliadas. Os níveis críticos de P para os clones Aupaba e F2 foram 5,2 e 6,3 mg dm-3 no solo e 1,03 e 1,11 g kg-1 nas folhas, respectivamente. A erva-mate é exigente em P, expressando produtividade máxima na fase de plantio, formação de copa 1 e 2 e produção, quando aplicado doses de P2O5 em torno de 5, 25, 40 g planta-1 e 35 kg ha-1, respectivamente.

Abstract Resin composites containing surface pre-reacted glass (S-PRG) have been introduced to reduce demineralization and improve remineralization of the tooth structure. However, water diffusion within the material is necessary for its action, which can impair its overall physicomechanical properties over time, including color stability. This study aimed to evaluate the color stability and related degree of conversion (DC) of four resin composites. Discs (6 x 4 mm, n = 5/group) of microhybrid (MH), nanofilled (NF), nanohybrid (NH), and S-PRG-based nanohybrid (S-PRG-NH) composites with two opacities (A2/A2E and A2O/A2D) were prepared. Color (CIELab and CIEDE2000) was evaluated with a spectrophotometer after aging in grape juice (2 x 10 min/10mL/7days). The DC was analyzed by using Fourier transform infrared spectroscopy before and after light-curing. Data were statistically analyzed by using two-way analysis of variance and post-hoc least significant difference tests (p<0.05). In the color stability analysis, the interaction between filler type and opacity was significant (CIELab, p = 0.0015; CIEDE2000, p = 0.0026). NH presented the highest color stability, which did not differ from that of MH. The greatest color alteration was observed for S-PRG-NH. S-PRG fillers also influenced DC (p < 0.05). The nanohybrid resin composite presented favorable overall performance, which is likely related to its more stable organic content. Notwithstanding the benefits of using S-PRG-based nanohybrid resins, mostly in aesthetic procedures, professionals should consider the susceptibility of such resins to color alteration, probably due to the water-based bioactive mechanism of action.

ABSTRACT Seed vigor is one of main attributes of the physiological quality from seed lot. Thus, identify which mechanisms are used by seeds of higher vigor that favor the formation of seedlings with better performance is a key aspect in agriculture. The enzyme activity of phytase and alpha-amylase favor the availability of phosphorus and sugars, respectively, during germination and can be determinants of seed vigor. Thus, the objective of the present work was to identify the association of phytase and alpha-amylase enzymes with the vigor of a seed lot of common beans. The results showed a positive correlation between seed vigor and the enzymes evaluated. Based on the findings, it can be concluded that seeds with high vigor have a high capacity to form seedlings with better performance, because they present high enzymatic activity. Also, in seed lots of the same genotype, they can be used to determine seed vigor during germination. Thus agriculture alphaamylase alpha amylase sugars respectively beans evaluated findings Also genotype

RESUMEN La Reserva Natural Pingüino rey (RNPR) en Bahía Inútil (Estrecho de Magallanes, Chile), protege la única colonia nidificante de pingüino rey (Aptenodytes patagonicus) que existe en Chile, y representa uno de los recursos ecoturísticos más visitados en la parte chilena de Tierra del Fuego. La vegetación en el área está dominada por la estepa patagónica, un paisaje desértico donde destacan plantas diminutas, con flores vistosas y cuya utilidad alimentaria, ritual y medicinal por el pueblo nómada cazador-recolector Selk’nam, es bien conocida. A pesar del importante hito que supone la RNPR, la información turística que allí se ofrece es limitada al pingüino rey, omitiendo el potencial relato que puede derivar del paisaje vegetal y la memoria etnográfica. Se realizó un inventario de la flora vascular del RNPR, y una exhaustiva revisión de literatura científica para evaluar el potencial de esta biodiversidad en la elaboración de una narrativa complementaria para uso ecoturístico. Sobre la base de criterios estéticos, etnobotánicos, fitoquímicos, distribucionales, ecológicos, históricos y de conservación, se seleccionaron 12 de las 85 especies registradas como potenciales plantas carismáticas. En este estudio proponemos, que los criterios mencionados pueden ser útiles para elaborar una narrativa, pero la calidad del contenido dependerá de la investigación científica disponible. También, sugerimos que las narrativas integrando plantas carismáticas, sus usos etnobotánicos y contexto ecológico, pueden ser herramientas complementarias para mejorar los contenidos del ecoturismo en la RNPR, interpretar la historia natural del área y así, enriquecer la experiencia del visitante para una mejor valoración de un patrimonio hasta ahora, poco conocido.

ABSTRACT The King Penguin Nature Reserve (KPNR) in Bahía Inútil (Strait of Magellan, Chile), protects the only King Penguin nesting colony (Aptenodytes patagonicus) that exists in Chile, and represents one of the most visited ecotourism resources in Chilean Tierra del Fuego Island. The vegetation in the area is dominated by the Patagonian steppe, a desert landscape where tiny plants stand out, with showy flowers and whose food, ritual and medicinal use was well known by the hunter-gatherer Selk’nam people. Despite the important milestone that the KPNR represents, the tourist information offered there is restricted to the King penguin, omitting the potential narratives that can be elaborated from the vegetal landscape and ethnographic memory. In this study, the vascular flora of the KPNR was inventoried, and an exhaustive review of scientific literature was carried out to evaluate the potential of this biodiversity in the elaboration of a complementary narrative for ecotourism. On the basis of aesthetic, ecological, distributional, ethnobotanical and historical criteria, 12 of the 85 registered species were selected for the preparation of narratives. In this study, we propose that the selected criteria may be useful to elaborate a story, but the quality of the content will depend on the available scientific research. Also, we suggest that narratives integrating charismatic plants, their ethnobotanical uses, ecological and historical context, can be complementary tools to improve the contents of ecotourism in the KPNR, interpreting the natural history of the area and thus, enrich the visitor’s experience for a better knowledge of a heritage until now, undervalued.

Resumen Este artículo analiza los estilos de gestión educativa en el pasado reciente en Argentina. La materialidad de este fenómeno se expresa en una serie de aristas, entre las que se destacan el tipo de burocracia que organiza la intervención del Estado, los instrumentos que se despliegan para tramitar la política educativa y el perfil de los actores que participan de la agenda y orientan el tratamiento de los asuntos relativos a la gestión educativa. La operación analítica que se propone consiste en exponer líneas de ruptura y de persistencia respecto de los modelos de gestión pública en el análisis de la administración educativa a nivel central y, a partir de ello, fortalecer la comprensión de las principales prácticas y experiencias que condujeron la gestión estatal en la materia.

Abstract This article analyzes the styles of educational management in the recent past in Argentina. The materiality of this phenomenon is expressed in a series of edges, among which the type of bureaucracy that organizes the State intervention, the instruments that are deployed to process educational policy and the profile of the actors that participate in the agenda and guide the treatment of the relative issues stand out. The proposed analytical operation consists of exposing the lines of rupture and persistence with respect to the models of public management in the analysis of educational administration at the central level, and from this, to strengthen the understanding of the main practices and experiences that led the state management in this area.

RESUMO OBJETIVOS Avaliar a qualidade dos dados antropométricos de crianças registradas no Sistema de Vigilância Alimentar e Nutricional (Sisvan) no período 2008-2017. MÉTODOS Estudo descritivo sobre a qualidade dos dados antropométricos de crianças menores de 5 anos atendidas nos serviços de atenção primária do Sistema Único de Saúde, a partir das bases de dados individuais do Sisvan. A qualidade dos dados foi avaliada anualmente por meio dos indicadores: cobertura, completude, razão entre sexos, distribuição da idade, preferência por dígitos de peso e estatura, valores de escore-z implausíveis, desvio-padrão e normalidade dos escores-z. RESULTADOS No total, 73.745.023 registros e 29.852.480 crianças foram identificados. A cobertura aumentou de 17,7% em 2008 para 45,4% em 2017. A completude da data de nascimento, peso e estatura correspondeu a quase 100% para todos os anos. A razão entre sexos foi equilibrada e aproximadamente similar a razão esperada, variando entre 0,8 e 1. A distribuição da idade revelou maiores percentuais de registros entre as idades de 2 a 4 anos até meados de 2015. Uma preferência pelos dígitos terminais “zero” e “cinco” foi identificada entre os registros de peso e estatura. As porcentagens de escores-z implausíveis excederam 1% para todos os índices antropométricos, com redução dos valores a partir de 2014. Uma alta dispersão dos escores-z, incluindo desvios-padrão entre 1,2 e 1,6, foi identificada principalmente nos índices incluindo estatura e nos registros de crianças menores de 2 anos e residentes das regiões Norte, Nordeste e Centro-Oeste. A distribuição dos escores-z foi simétrica para todos os índices e platicúrtica para estatura/idade e peso/idade. CONCLUSÕES A qualidade dos dados antropométricos do Sisvan para crianças menores de 5 anos melhorou substancialmente entre 2008 e 2017. Alguns indicadores requerem atenção, sobretudo para medidas de estatura, cuja qualidade foi principalmente inferior entre os grupos mais vulneráveis a agravos nutricionais.

ABSTRACT OBJECTIVE To evaluate the quality of anthropometric data of children recorded in the Food and Nutrition Surveillance System (SISVAN) from 2008 to 2017. METHOD Descriptive study on the quality of anthropometric data of children under five years of age admitted in primary care services of the Unified Health System, from the individual databases of SISVAN. Data quality was annually assessed using the indicators: coverage, completeness, sex ratio, age distribution, weight and height digit preference, implausible z-score values, standard deviation, and normality of z-scores. RESULTS In total, 73,745,023 records and 29,852,480 children were identified. Coverage increased from 17.7% in 2008 to 45.4% in 2017. Completeness of birth date, weight, and height corresponded to almost 100% in all years. The sex ratio was balanced and approximately similar to the expected ratio, ranging from 0.8 to 1. The age distribution revealed higher percentages of registrations from the ages of two to four years until mid-2015. A preference for terminal digits “zero” and “five” was identified among weight and height records. The percentages of implausible z-scores exceeded 1% for all anthropometric indices, with values decreasing from 2014 onwards. A high dispersion of z-scores, including standard deviations between 1.2 and 1.6, was identified mainly in the indices including height and in the records of children under two years of age and residents in the North, Northeast, and Midwest regions. The distribution of z-scores was symmetric for all indices and platykurtic for height/age and weight/age. CONCLUSIONS The quality of SISVAN anthropometric data for children under five years of age has improved substantially between 2008 and 2017. Some indicators require attention, particularly for height measurements, whose quality was lower especially among groups more vulnerable to nutritional problems.

Abstract This descriptive ecological study sought to analyze the inductive role of a federal financial incentive passed on to Brazilian municipalities in 2020, during the COVID-19 pandemic, in increasing the number of individual consultations for the condition of obesity in primary health care (PHC). Secondary data obtained from the Health Information System for Primary Care and from the Food and Nutrition Surveillance System (SISVAN) were used. In 2021, 74.8% of the 5,504 municipalities that received the financial incentive, showed an increase in the number of individual obesity consultations in PHC, compared to 2020. The number of people identified with obesity and the number of individual visits for this condition were higher in 2021 than in the other years analyzed (2017 to 2020). Comparing 2021 with 2020 (year of receipt of the financial incentive), it was observed that the percentage of increase in the number of individual consultations for the condition of obesity was higher than the increase in the number of people identified with obesity in the SISVAN (77.6 % vs. 39.1%). In conclusion, federal financial incentives for municipalities, channeled to enhance care for people with obesity within the scope of PHC, are important mechanisms for inducing actions at the local level.

Resumo O presente estudo ecológico descritivo objetivou analisar o papel indutor de um incentivo financeiro federal repassado aos municípios brasileiros em 2020, em meio à pandemia de COVID-19, no aumento do número de atendimentos individuais para a condição de obesidade na atenção primária à saúde (APS). Utilizaram-se dados secundários, obtidos no Sistema de Informação em Saúde para a Atenção Básica e no Sistema de Vigilância Alimentar e Nutricional (SISVAN). Em 2021, 74,8% dos 5.504 municípios que receberam o incentivo financeiro apresentaram aumento no número de atendimentos individuais para a condição avaliada como obesidade na APS, em relação a 2020. O número de pessoas identificadas com obesidade e o número de atendimentos individuais para esta condição foram maiores em 2021 do que nos demais anos analisados (2017 a 2020). Na comparação de 2021 com 2020 (ano de recebimento do incentivo financeiro), observou-se que o percentual de aumento de atendimentos individuais foi superior ao percentual de aumento de pessoas com obesidade registradas no SISVAN (77,6% vs. 39,1%). Em conclusão, incentivos financeiros federais, canalizados para o fortalecimento do cuidado às pessoas com obesidade no âmbito da APS, figuram como importantes mecanismos de indução de ações em nível local.

Abstract The effectiveness of at-home dental bleaching treatments depends on the time that bleaching products are in contact with the teeth surface and, consequently, on the adequate use of associated custom acetate trays. Objective This randomized single-blinded trial aimed to analyze if the daily usage time of these products influences the patient’s compliance behavior when submitted to monitored at-home dental bleaching. Secondary outcomes were color change and tooth sensitivity. Methodology Sixty-six volunteers were randomly distributed into three groups (n=22): patients were instructed to use the trays for 2 (G2), 4 (G4), and 8 (G8) hours daily. The daily dental bleaching compliance behavior was measured using a microsensor inserted into the trays. Subjective and objective color evaluation assessments were adopted at baseline (T0), one (T1), two (T2), and three weeks (T3) after the beginning of the bleaching treatment, as well as two weeks after the treatment (T4). Tooth sensitivity was analyzed using the VAS scale, ranging from T1 to T4. Results G2 showed a greater degree of cooperation than G8 and cooperation was inversely proportional to the recommended usage time. Significantly higher color change was observed in the upper arch for G8 when compared to G2 in subjective analysis, from T1 to T4. There were no statistical differences between the groups in objective analysis. Conclusion Shorter recommended usage time of the bleaching product may improve the patient's compliance with at-home dental bleaching treatments. However, increased daily usage time may promote better subjective color change. Bleaching sensitivity was more significant in the first week for a longer time of use.

ABSTRACT Despite the great economic importance of yerba mate (Ilex paraguariensis A. St.-Hil.), information about clonal plantations and planting conditions of this tree is still scarce. Thus, we evaluated initial field establishment of five clonal yerba mate cultivars, planted at three seasons of the year (summer, autumn, and spring) in a shaded environment, and in the autumn, we also established blocks in a full sunlight environment, to compare both cultivation environments. We evaluated plants at 3, 6, 9, and 12 months after planting, counting the surviving plants, shoots number, and measuring height and canopy diameter. At 12 months we also analyzed the caffeoylquinic acids (CQA) contents in mature leaves from different environments. Plant survival and growth were not affected by planting seasons. Cultivars Aupaba and BRS 409 had the highest survival rates in all seasons evaluated. The shaded environment provided greater survival and growth than full sunlight, also showing higher CQA levels in the leaves. Clonal cultivars Aupaba, BRS 408, and BRS 409 presented higher growth in both environments. The severe drought in the first year may have affected survival; however, growth was considered satisfactory and plants’ initial establishment was better in the shaded environment.

ABSTRACT The objective of this study was to evaluate the effects of replacing choline chloride with a plant source of choline on the locomotor system, liver health, and development of breast myopathies in broilers aged 1-42 days of age. We allocated 1,120 one-day-old Cobb broilers to four treatment groups and fed them commercial diets based on corn and soybean meal. The treatments included choline in the form of 1,800.00 mg/kg choline chloride; 1,350.00 mg/kg choline chloride + 450.00 mg/kg herbal choline; 900.00 mg/kg choline chloride + 900.00 mg/kg herbal choline; and 1,000.00 mg/kg herbal choline. Each treatment group had eight replications. Throughout the experiment, gait score, footpad dermatitis, hock burn, and leg deformities (valgus and varus) were evaluated in the birds at 28 and 35 days of age. After slaughter, parameters such as breast myopathies, tibial dyschondroplasia score, and histological slides of the pectoral muscle, liver, and proximal tibial epiphysis were assessed. The results demonstrated good hepatic and locomotor health in the broilers, as no classical signs of choline deficiency were observed. Statistical analyses indicated no significant differences between treatments in terms of liver and locomotor health, suggesting that broilers fed diets supplemented with the plant source did not experience choline deficiency. Additionally, no statistically significant differences were found between treatments regarding breast myopathies. Overall, the tested choline plant source can effectively replace choline chloride in broiler diets.

Abstract The objective of this work was to determine the force required to detach fruits of Conilon coffee (Coffea canephora) genotypes in five maturation stages, to determinate the best stage for mechanized harvest, and to verify the possibility of future selections of genotypes adapted to mechanized harvesting. Harvests were carried out in the 2013/2014 crop season, and the detachment force was determined based for six fruits from each side of the crop row, collected randomly from the middle third of the plants. The detachment force curve was obtained for each cycle through logistic regression, using the R software. According to the duration of their cycle, the genotypes were divided into super early, early, medium, and semilate; the values of the coefficients of the detachment force curve equation were also obtained. There is genetic variability regarding fruit detachment force throughout the maturation cycle, which indicates the possibility of selecting genotypes adapted to mechanized harvesting. Fruit detachment force shows a considerable drop in the final stages of maturation. The raisin stage is the best for the mechanized harvest of irrigated Conilon coffee in the Cerrado.

Resumo O objetivo deste trabalho foi determinar a força requerida para o desprendimento de frutos de genótipos de café conilon (Coffea canephora) em cinco estádios de maturação, determinar o melhor estádio para a colheita mecanizada e verificar a possibilidade de futuras seleções de genótipos adaptados à colheita mecanizada. As colheitas foram realizadas na safra de 2013/2014, e a força de desprendimento foi determinada para seis frutos de cada lado da linha de cultivo, colhidos aleatoriamente no terço médio das plantas. A curva de força de desprendimento foi obtida para cada ciclo, por meio de regressão logística, tendo-se utilizado o programa R. De acordo com a duração de seu ciclo, os genótipos foram divididos em superprecoces, precoces, médios e semitardios; também foram obtidos os valores dos coeficientes da equação da curva de força de desprendimento. Há variabilidade genética quanto à força de desprendimento dos frutos ao longo do ciclo de maturação, o que indica a possibilidade de seleção de genótipos adaptados à colheita mecanizada. A força de desprendimento dos frutos apresenta queda considerável nos estádios finais de maturação. A fase passa é a melhor para a colheita mecanizada do café conilon irrigado no Cerrado.

Resumo A erva-mate (Ilex paraguariensis) é uma espécie nativa do Brasil e fortemente ligada à cultura e à história dos estados da região sul do Brasil, seu maior produtor e exportador mundial. Entretanto, o desempenho produtivo dos ervais cultivados brasileiros vem diminuído ao longo dos últimos anos, a despeito das tecnologias de produção à disposição dos produtores. Diante disso, o objetivo deste trabalho foi estudar fatores que afetam a produtividade em função de níveis de produtividade da erva-mate cultivada. Para tanto, foram coletados dados a partir da aplicação de questionários estruturados em 470 propriedades rurais, distribuídos em toda a região produtora no Brasil. As propriedades foram agrupadas em níveis de produtividade utilizando a produtividade média e o seu desvio-padrão e a adoção tecnológica foi comparada entre os níveis. Para identificar as tecnologias mais determinantes para a produtividade, foi utilizado o modelo de regressão logística multinomial. De acordo com os resultados obtidos no presente estudo, os ervais cultivados são conduzidos por uma agricultura familiar diversificada, havendo o predomínio do baixo acesso à assistência técnica e ao aporte tecnológico. As propriedades com alto nível de produtividade apresentaram maior adoção tecnológica, maior presença da assistência técnica e maior capacitação da mão de obra. Entre as tecnologias avaliadas, a adubação, as mudas melhoradas, o controle de plantas daninhas, o controle de pragas, as ferramentas de poda e a poda de limpeza foram determinantes para a obtenção de médio e alto nível de produtividade. Dessa forma, políticas públicas que envolvam a capacitação e a transferência de tecnologias devem ser estimuladas no setor ervateiro, a fim de estimular a incorporação de novas tecnologias nos ervais brasileiros.

Abstract The yerba mate (Ilex paraguariensis) is a species native to Brazil which is strongly linked to the culture and history of the states of southern Brazil, the world's largest producer and exporter. However, the productive performance of yerba mate plantations in Brazil has decreased over the last few years, despite of the available technologies to producers. Therefore, the objective of this work was to study factors that affect the productivity as a function of productivity levels of cultivated yerba mate. The data were collected by applying structured questionnaires in 470 farms distributed throughout the yerba mate-producing region in Brazil. The properties were grouped into productivity levels using the average productivity and its standard deviation, and the technological adoption was compared between the levels. The multinomial logistic regression model was used to identify the most determinant technologies for productivity. According to our results, the cultivated yerba mate is conducted by diversified family agriculture, with a predominance of low access to technical assistance and technology. Properties with a high level of productivity showed higher technological adoption, a more significant presence of technical assistance, and greater workforce training. Among the evaluated technologies, fertilization, improved seedlings, weed control, pest control, pruning tools, and cleaning pruning were determinants for medium and high productivity levels. Thus, public policies involving training and transfer of technologies should be encouraged in the yerba mate sector to stimulate the incorporation of new technologies in the Brazilian yerba mate plantations.
