Resumo: | The rhizosphere contains many microorganisms that can promote plant growth and protect the root system against infection by pathogens. Fungi of Trichoderma sp. are included in this group. The aim of this study was to evaluate efficiency of the inoculation of Trichoderma in agronomic performance of cowpea under field conditions, in the savanna in Gurupi, Tocantins, in harvests 2013/2014 to 2014/2015. The treatments consisted in seed treatment, with and without inoculation with Trichoderma asperellum UFT 201 with minimum concentration of viable conidia of 2x109 L-1, at a dose of 20 g kg-1 of seed. Biomass evaluations were made on efficiency, initial and final stands and survival in the use of Trichoderma in the stand maintaining and productivity. The results indicated that the ability of bio-protection and plant growth promotion were of great importance for the biomass production, the stand maintaining and cowpea productivity. In both harvests, survival was superior in the plants treated with Trichoderma, 23.0 and 13.2%, respectively, and yields were 9.5% higher compared to control for the two harvests. In general, the inoculation of Trichoderma provided the best results in the biomass variables analyzed for the two crops with higher productivity. |

Neste grupo incluem-se fungos de Trichoderma sp. O objetivo deste estudo foi avaliar a eficiência da inoculação de Trichoderma na performance agronómica de feijão-frade em condições de campo, na savana em Gurupi, Tocantins, nas campanhas de 2013/2014 a 2014/2015. Os tratamentos consistiram sementes inoculadas (ou não) com Trichoderma asperellum UFT 201 com uma concentração de conídios viáveis mínima de 2x109 L-1, numa dose de 20 g kg-1 de semente. Foram efetuadas avaliações de biomassa em termos de eficiência, populações iniciais e finais e sobrevivência de Trichoderma, e na manutenção e produtividade da cultura. Os resultados indicam que a capacidade de bioproteção e promoção do crescimento vegetal foram de grande importância para a produção de biomassa, a manutenção da cultura e a produtividade de feijão-frade. E mambas as campanhas a sobrevivência foi superior nas plantas tratadas comTrichoderma, 23,0 e 13,2% respetivamente, e as produtividades foram 9,5% superiores ao controlo em ambas as campanhas. Em termos globais, a inoculação com Trichoderma providenciou os melhores resultados nas diversas variáveis ilustradoras de biomasse para as duas campanhas, conduzindo a uma maior produtividade.Sociedade de Ciências Agrárias de Portugal2019-01-07T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/RCA15112eng2183-041X0871-018XChagas, Lilian F.B.Castro, Henrique G. deColonia, Brigitte S.O.Filho, Magno R.C.Miller, Luciane O.Chagas Junior, Aloisio Freitasinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:24:26Zoai:ojs.revistas.rcaap.pt:article/16399Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:30:50.998775Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
