Resumo: The no-tillage farming has become a popular practice in Brazil, but problems with weed control and plant nutrition persist under organic production systems. This study aimed at evaluating the agronomic traits and yield of maize, after using different off-season cover crops under two organic no-tillage systems. A randomized block design, with a 7 x 2 factorial scheme, being 7 treatments (weeds; black oat monoculture; sunflower; white lupin intercropped with black oat in rows; white lupin intercropped with black oat by broadcasting; white lupin monoculture; and no cover crop) and 2 cropping systems (maize alone and intercropped with jack bean), and four replications was used. The agronomic traits evaluated were plant height, first-ear insertion height, stem diameter, prolificacy, 1,000 grain weight, grain yield and nitrogen released at 60 days of mulch decomposition. White lupin straw in monoculture and intercropped with black oat release a higher amount of N during the decomposition process and, consequently, these treatments increase maize yield. Intercropping with jack bean within the same row as maize reduces its yield potential under an organic no-tillage system.

Objetivou-se avaliar as características agronômicas e a produtividade de milho, após a utilização de diferentes plantas de cobertura na entressafra, em dois sistemas de plantio direto orgânico. Utilizou-se delineamento em blocos casualizados, com 4 repetições, em esquema fatorial 7 x 2, sendo 7 manejos (plantas espontâneas; aveia preta em monocultivo; girassol; consórcio em fileiras de tremoço branco e aveia preta; consórcio à lanço de tremoço branco e aveia preta; tremoço branco em monocultivo; e manejo sem cobertura vegetal) e 2 modos de cultivo (milho solteiro e consorciado com feijão-de-porco). Avaliaram-se as seguintes características agronômicas: altura da planta, altura da inserção da espiga principal, diâmetro do colmo, prolificidade, massa de 1.000 grãos, produtividade de grãos e nitrogênio liberado aos 60 dias de decomposição da palhada. A palhada de tremoço branco em monocultivo e os consórcios com aveia preta liberam maior quantidade de N durante o processo de decomposição e, consequentemente, estes manejos elevam a produtividade do milho. O consórcio de feijão-de-porco na mesma linha de cultivo do milho reduz seu potencial produtivo em sistema de plantio direto orgânico.Escola de Agronomia - Universidade Federal de Goiás2017-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/42774Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 1, Jan./Mar. 2017; 72-79Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 1, jan./mar. 2017; 72-79Pesquisa Agropecuária Tropical; v. 47, n. 1, jan./mar. 2017; 72-791983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/42774/22658Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessBrito, Lamara FreitasGalvão, João Carlos CardosoGiehl, JefersonCampos, Silvane de AlmeidaCoelho, Steliane Pereira2020-07-13T18:28:25Zoai:ojs.revistas.ufg.br:article/42774Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:14.944869Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
