O uso da horta escolar no ensino fundamental I: um estudo bibliométrico 
The use of school gardens has a history in early childhood education around the world.In the last decades, international and national institutions, as well as several researchers, have strongly encouraged the use of school gardens, in order to stimulate the construction of knowledge about nutritional and environmental education.Given the growing interest in the subject, the objective of this research was to carry out a bibliometric study with the intention of quantifying and qualifying the scientific studies published in the last 14 years, which are based on the use of the school garden as a didactic tool for teaching in basic education.A bibliometric study of scientific articles was carried out on the Capes journal Portal, using the keywords, "horta escolar" and "school garden", published in the last 14 years.The data were grouped into distribution and percentage graphs, according to the year of publication, authorship, pedagogical purposes (nutritional or environmental education and other pedagogical purposes), and school level of the studies.An experience report was also carried out to discuss the importance and feasibility of school gardens.A total of 125 articles were found.Of these, 22 articles (18% of the total) used the keyword "horta escolar" and 103 articles (82% of the total) used the keyword "school garden".It was observed that, of the total number of articles found, 50% were addressed to Elementary School I, 39% corresponded to works focused on other levels of basic education and 11% had no identification of the school level at which the research was carried out.The qualitative approach showed that the use of the school garden has a great plasticity of pedagogical approaches in the works consulted.These approaches involve nutritional education (36% "school garden" x 37% "horta escolar"), environmental education (17% "school garden" x 40% "horta escolar") and other pedagogical purposes (47% "school garden" x 23% "horta escolar").Many works and also the experience report demonstrate the need for partnerships between schools, public agents, family and community for the sustainability of school gardens.The approaches found in the works mainly involve nutritional education and environmental education, mainly in the works of Brazilian authors.Of these, many works focus on encouraging family agriculture and ecology.Other didactic purposes for using the school gardens were: literacy, literature, personal relationships, arts, mathematics, topics in natural science, chemistry, language learning, culture, history and geography.In developed countries where the school garden culture is already more present and linked to the school curriculum, the parameters for evaluating the effectiveness, integration and sustainability of school gardens are also studied by several researchers.Finally, works with subjects on architecture, history of school gardens and the use of technological tools to measure the integration of school gardens still appeared.
