Resumo: | Organic production systems should be implanted using organic seeds free of microorganisms and without chemicals application. Neem extracts has been shown to be efficient to control seed microorganism, however its effects on the physiological seed quality, is still unknown. The aim of this work was to identify the viability of aqueous extract of neem leaf as an alternative to the chemical treatment in tomato seeds Super Marmande cultivar. The experiment was carried out in a laboratory of the State University of Piauí campus Corrente. Different concentrations of neem aqueous extract were prepared using 0, 40, 80, 120, 160 and 200 grams of neem leaves per 1 liter of distilled water. Doses of each concentration containing 8 ml of the aqueous extract were used to treat 100 tomato seeds. A dose of thiran (3 grams per kilogram of seed) was used as chemical control. After the treatment, seeds were evaluated for germination, first counting of germination, cold, field seed emergence, emergence speed index, dry matter of seedlings and frequency index of contaminants. For this study a completely randomized design was emplyed, with 7 treatments and 4 replicates. None of the neem aqueous extracts concentrations altered physiological quality of tomato seeds. Moreover, the neem extracts with a concentration of 160 and 200 g L-1 were efficient to reduce contaminants present in the seeds. Based on our results, the application of neem extracts could be an efficient alternative for organic treatment of tomato seeds replacing chemical treatments. |

Extratos de neem têm apresentado eficiência no controle de microrganismo, porém o efeito do neem na qualidade fisiológica das sementes tratadas por ele é pouco conhecido. Objetivou-se, no presente trabalho, propor extrato aquoso de folha de neem, alternativo ao tratamento químico de semente de tomate cultivar Super Marmande. O experimento foi realizado na Universidade Estadual do Piauí campus Corrente. Produziram-se diferentes concentrações de extrato aquoso de neem utilizando 0, 40, 80, 120, 160 e 200 g de folha para cada L de água destilada. Doses de cada concentração contendo 8 ml do extrato aquoso foram utilizadas para tratar 100 sementes de tomate, além da dose de Thiran utilizando 3 gramas por quilo de semente (testemunha químico). Após tratadas as sementes foram submetidas às avaliações de germinação, primeira contagem da germinação, frio, emergência a campo, índice de velocidade de emergência, matéria seca das plântulas e índice de frequência de contaminantes. Utilizou-se o delineamento inteiramente ao acaso com 7 tratamentos em 4 repetições. Nenhuma das concentrações com extratos aquosos de folha de neem alteraram a qualidade fisiológica das sementes de tomate, porém apenas as concentrações contendo 160 e 200 g L-1 foram eficientes na redução de contaminantes presentes nas sementes. Diante dos dados obtidos recomenda-se para o tratamento orgânico de sementes de tomate utilizar extrato aquoso de neem nas concentrações entre 160 e 200 g L-1 como alternativa ao tratamento químico.Editora Verde2019-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/577210.18378/rvads.v14i1.5772Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 14 No. 1 (2019); 01 - 04Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 14 Núm. 1 (2019); 01 - 04Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 14 n. 1 (2019); 01 - 041981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/5772/5978https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5772/5979Copyright (c) 2019 Leomara Vieira de França Cardozo and Moisés Vieira Pinhão Netoinfo:eu-repo/semantics/openAccessCardozo, Leomara Vieira de FrançaPinhão Neto, Moisés Vieira2021-06-14T13:13:45Zoai:ojs.gvaa.com.br:article/5772Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:27.989581Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
