Resumo: | 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. |

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.Universidade Federal de Santa Maria2022-09-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6366110.5902/1980509863661Ciência Florestal; Vol. 32 No. 3 (2022); 1345-1367Ciência Florestal; v. 32 n. 3 (2022); 1345-13671980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/63661/48986https://periodicos.ufsm.br/cienciaflorestal/article/view/63661/50947Copyright (c) 2022 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessGoulart, Ives Clayton Gomes dos ReisSantin, DelmarBrasileiro, Bruno Portela2022-12-29T17:36:43Zoai:ojs.pkp.sfu.ca:article/63661Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2022-12-29T17:36:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
