Resumo: Cover crops are used as a strategy to recover degraded soils, improving their physical, chemical and biological characteristics, as well as assisting in the control of weeds through allelochemical compounds released by the shoot degradation process. This work aimed to evaluate the phytotoxicity of the aqueous extract of the cover crops Raphanus sativus L., Avena strigosa (Schreb) and Vicia villosa R. on the germination and initial growth of Zea mays, Amaranthus spinosus L. and Ipomoea grandifolia (Dammer) O'Donnell, as well as to identify and quantify the phenolic compounds present in the extract. Straws from the dried and crushed cover crops were used. The extracts were obtained by mixing 10% R. sativus and A. strigosa, and 12% V. villosa in distilled water (m/v). DIC was used, with four replications, in a 3x4 factorial scheme, with 3 cover crops (R. sativus, A. strigosa and V. villosa) and 4 concentrations (0%, 25%, 50% and 75%). The variables analyzed were: germination, germination speed index (GSI), seedling growth, root protrusion (RP), root protrusion speed index (RPSI) and dry mass of the root and shoot. Higher concentrations of the extracts affected the initial development of maize and weeds. The phenolic compounds identified in greater quantity were benzoic acid, p-coumaric acid, followed by ferulic acid and p-hydroxybenzoic acid. It is suggested that studies of the same nature be carried out in the field, since the interactions between soil microorganisms, climatic conditions can interfere with the results.

Este trabajo tuvo como objetivo evaluar la fitotoxicidad del extracto acuoso de los abonos verdes Raphanus sativus L., Avena strigosa (Schreb) y Vicia villosa R. sobre la germinación y crecimiento inicial de Zea mays, Amaranthus spinosus L. e Ipomoea grandifolia. (Dammer) O'Donnell, además de identificar y cuantificar los compuestos fenólicos presentes en el extracto. Se utilizaron pajitas de las plantas de abono verde secas y trituradas. Los extractos se obtuvieron mezclando 10% de R. sativus y A. strigosa y 12% de V. villosa en agua destilada (m/v). Se utilizó DIC, con cuatro repeticiones, en un esquema factorial 3x4, con 3 abonos verdes (R. sativus, A. strigosa y V. villosa) y 4 concentraciones (0%, 25%, 50% y 75%). Las variables analizadas fueron: germinación, índice de velocidad de germinación (IVG), crecimiento de plántula, protrusión de raíz (PR), índice de velocidad de protrusión de raíz (IVPR) y masa seca de la raíz y parte aérea. Las concentraciones más altas de los extractos afectaron el desarrollo inicial del maíz y las malezas. Los compuestos fenólicos identificados en mayor cantidad fueron ácido benzoico, ácido p-cumárico, seguido del ácido ferúlico y ácido p-hidroxibenzoico. Se sugiere que se realicen estudios de la misma naturaleza en campo, ya que las interacciones entre microorganismos del suelo, condiciones climáticas pueden interferir en los resultados.Plantas de adubação verde (PAV) são utilizadas na estratégia de recuperar os solos degradados, melhorando suas características físicas, químicas e biológicas, além de auxiliar no controle de plantas espontâneas através de compostos aleloquímicos liberados pelo processo de degradação da parte aérea. Este trabalho objetivou avaliar a fitotoxicidade do extrato aquoso das plantas de adubação verde (PAV) Raphanus sativus L., Avena strigosa (Schreb) e Vicia villosa R. sobre a germinação e o crescimento inicial de Zea mays, Amaranthus spinosus L. e Ipomoea grandifolia (Dammer) O’Donnell, bem como identificar e quantificar os compostos fenólicos presentes no extrato. Foram utilizadas palhadas das plantas de adubação verde secas e trituradas. Os extratos foram obtidos misturando 10% de R. sativus e A. strigosa, e 12% de V. villosa em água destilada (m/v). Foi utilizado DIC, com quatro repetições, em esquema fatorial 3x4, sendo 3 PAV (R. sativus, A. strigosa e V. villosa) e 4 concentrações (0%, 25%, 50% e 75%). As variáveis analisadas foram: germinação, índice de velocidade de germinação (IVG), crescimento de plântula, protrusão radicular (PR), índice de velocidade de protrusão radicular (IVPR) e Massa Seca da raiz e da parte aérea. Maiores concentrações dos extratos afetaram o desenvolvimento inicial do milho e das plantas daninhas. Os compostos fenólicos identificados em maior quantidade foram ácido benzoico, ácido p-cumarico, seguidos pelo ácido ferúlico e ácido p-hidroxibenzócio. Sugere-se que estudos da mesma natureza sejam realizados a campo, visto que as interações entre os microrganismos do solo, as condições climáticas podem interferir nos resultados.Research, Society and Development2020-10-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/857910.33448/rsd-v9i10.8579Research, Society and Development; Vol. 9 No. 10; e5859108579Research, Society and Development; Vol. 9 Núm. 10; e5859108579Research, Society and Development; v. 9 n. 10; e58591085792525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/8579/7957Copyright (c) 2020 Maicon Reginatto; Lisandro Tomas da Silva Bonome; Leonardo Khaôe Giovanetti; Henrique von Hertwig Bittencourt; Luciano Tormen; Paulo Cesar Conceiçãohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessReginatto, MaiconBonome, Lisandro Tomas da SilvaGiovanetti, Leonardo Khaôe Bittencourt, Henrique von HertwigTormen, LucianoConceição, Paulo Cesar2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/8579Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:01.150076Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
