Summary: The use of cover crops, especially in summer in off-season, is an uncommon practice because they compete with crops of economic importance. The objective was to evaluate the use of cover crops, soil cover and suppression of weeds in the corn-wheat off-season in northwest of Rio Grande do Sul. For this, sunn hemp, gray mucuna, jack bean, lupine, buckwheat, millet, millet, and sunn hemp intercrop (50%) and fallow (control) were used. The species were sown after harvesting the corn crop with 0.45 m spacing between rows in randomized blocks with six replications. The soil cover rate was analyzed at 30, 45, 60, 75 and 90 days after sowing. Dry matter was determined at full flowering of each crop, separated into stalks/stems and leaves, and dried at 65ºC. The incidence of weeds was evaluated at the time of full flowering. In the off-season, millet, millet + crotalaria, gray mucuna and jack bean intercropped have greater soil cover efficiency, both reaching 100% soil cover. The highest accumulations of dry matter were from millet (11,204 kg.ha-1) and intercropped (9291 kg.ha-1). The most efficient crops for the suppression of weeds were pearl millet, intercropped and gray mucuna. Sunn hemp and buckwheat showed low performance; therefore, they are not recommended for single cultivation in the corn-wheat off-season.

O objetivo foi avaliar o uso de plantas de cobertura, na cobertura do solo e supressão de plantas espontâneas na entressafra milho-trigo no noroeste do Rio Grande do Sul. Para isso, utilizou-se crotalária espectabilis, mucuna-cinza, feijão-de-porco, tremoço, trigo-mourisco, milheto, consórcio de milheto e crotalária (50%) e pousio (testemunha). As espécies foram semeadas após a colheita do milho safra com 0,45 m de espaçamento entre linhas em blocos ao acaso com seis repetições. A taxa de cobertura do solo foi analisada aos 30, 45, 60, 75 e 90 dias após a semeadura. A matéria seca foi determinada na plena floração de cada cultura, separada em talos/colmos e folhas e secos a 65ºC. A incidência de plantas espontâneas foi avaliada no momento de plena floração. No período entressafra o milheto, consórcio de milheto + crotalária, mucuna-cinza e feijão-de-porco apresentam maior eficiência de cobertura do solo, ambos atingindo 100% de cobertura de solo. Os maiores acúmulos de matéria seca foram do milheto (11.204 kg.ha-1) e consórcio (9291 kg.ha-1). As culturas mais eficientes para a supressão de plantas espontâneas foram o milheto, o consórcio e a mucuna-cinza. A crotalária e trigo-mourisco apresentaram baixo desempenho, logo, não são recomendadas para cultivo solteiro na entressafra milho-trigo.Universidade do Estado de Santa Catarina2023-08-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/2312210.5965/223811712232023403Revista de Ciências Agroveterinárias; Vol. 22 No. 3 (2023); 403-413Revista de Ciências Agroveterinárias; v. 22 n. 3 (2023); 403-4132238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/23122/15898Copyright (c) 2023 Authors & Revista de Ciências Agroveterináriasinfo:eu-repo/semantics/openAccessRuaro, Eduarda LetíciaRamos , Marco Aurélio Camargo de Redin, Marciel 2024-02-29T12:11:35Zoai::article/23122Revistahttps://periodicos.udesc.br/index.php/agroveterinaria/PUBhttps://periodicos.udesc.br/index.php/agroveterinaria/oairca.cav@udesc.br | portal.periodicos@udesc.brhttps://doi.org/10.5965/223811712238-11711676-9732opendoar:2024-02-29T12:11:35Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
