Este artigo é um produto da pesquisa realizada para o mestrado em Educação, cujo objeto é o projeto político pedagógico apresentado pela UNESCO para educação patrimonial, por meio das iniciativas por ela encorajadas para preservação do patrimônio cultural e natural. A partir de uma pesquisa qualitativa de análise documental das recomendações, declarações e convenções da UNESCO, foi possível reconstruir as propostas e usos políticos da educação patrimonial e projetos político pedagógicos planejados por esta agência. O resultado apresentado é um panorama da política pedagógica idealizada para a preservação patrimonial e sua exploração econômica, seja como suporte para criação de redes sustentáveis para comunidades tradicionais, exploração responsável pelo turismo cultural por agentes públicos e privados e responsabilidade científica e pedagógica na preservação de bens culturais materiais e imateriais. A contribuição deste artigo é, ao final, uma reflexão sobre a importância do estabelecimento de critérios para avaliar os impactos destes projetos políticos pedagógicos para o público por ele visado.
Glyphosate is the most used product for weed control in young coffee planting rows. The application is carried out in a directed way, avoiding the contact of the product with the crop. However, drift and consequent plant injuries frequently occur. An alternative to reduce these injuries is the use of attenuators capable of reducing the negative effects caused by this herbicide. Therefore, the objective of this study is to verify the efficiency of foliar fertilizers (Fertiactyl Pós ® and Crop + ) as attenuators of the toxic effects caused by the use of glyphosate in the coffee crop. Thus, coffee seedlings were subjected to different doses of the mixture of Fertiactyl Pós ® with glyphosate and Crop + with glyphosate. The treatments were applied on top of the plants. The percentage of coffee intoxication was evaluated at 14, 21, 28, 35, 42 and 90 days after application. At 90 days after application, height, leaf area and shoot and root dry matter were evaluated. Higher doses of glyphosate (1.44 and 2.88 kg ha -1 ) without the use of attenuators caused intoxication levels close to 80% at 28 and 90 DAA. The use of Fertiactyl Pós ® and Crop + reduced the injuries caused by the application of glyphosate, regardless of the dose of herbicide and fertilizers, but with different levels of action. All the morphological variables measured suffered a negative action with the isolated use of glyphosate, with a tendency to recover when the attenuators were applied. It is concluded that the two attenuators were efficient in suppressing the deleterious effects of glyphosate on coffee plants affected by this herbicide. For 0.720 kg ha -1 of glyphosate, the dose most used in the field, 8 L ha -1 is recommended for Fertiactyl Pós ® and 4 L ha -1 for Crop + .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
