Resumo: Maize intercropped with perennial green manure is an option to promote soil coverage, control weeds and recycle soil nutrients, in an organic system. This study aimed at evaluating the agronomic characteristics and yield of grains and organic maize straw intercropped with perennial green manures sown at different maize growth stages. A 3 x 2 + 1 factorial design was used, with three perennial species of green manure - calopogonium (Calopogonium mucunoides Desv.), tropical kudzu [Pueraria phaseoloides (Roxb.) Benth] and perennial soy [Neonotonia wightii (Wight & Arn) Lackey] - and two green manure sowing times - at the maize V4 (four expanded leaves) and VT (bolting) stages - plus a control treatment (maize monoculture). A randomized blocks design, with four replications, was used. Soil coverage, production of green manures dry matter and weeds, and maize growth and production variables were evaluated. The sowing of green manures at the V4 stage had a higher percentage of soil coverage, in relation to the VT stage. Calopogonium, when compared to the other green manure species, had the highest percentage of soil coverage (35.63 %) and dry matter (1.0 Mg ha-1). Perennial green manures grown intercropped with maize did not affect growth, grain yield and maize straw. However, they were not effective in suppressing weeds.

Objetivou-se avaliar as características agronômicas e produtividade de grãos e de palhada de milho orgânico em consórcio com adubos verdes perenes, semeados em diferentes estádios fenológicos do milho. Utilizou-se esquema fatorial 3 x 2 + 1, com três espécies perenes de adubos verdes - calopogônio (Calopogonium mucunoides Desv.), puerária [Pueraria phaseoloides (Roxb.) Benth] e soja-perene [Neonotonia wightii (Wight & Arn) Lackey] - e duas épocas de semeadura dos adubos verdes - estádios V4 (quatro folhas expandidas) e VT (pendoamento) do milho - mais um tratamento controle (milho em monocultivo). Utilizou-se delineamento em blocos casualizados, com quatro repetições. Avaliou-se a cobertura do solo, produção de massa seca dos adubos verdes e das plantas espontâneas e variáveis de crescimento e produção do milho. A semeadura dos adubos verdes, no estádio V4, proporcionou maior porcentagem de cobertura do solo, em relação ao VT. O calopogônio, quando comparado aos demais adubos verdes, apresentou maior porcentagem de cobertura do solo (35,63 %) e massa seca (1,0 Mg ha-1). Os adubos verdes perenes cultivados em consórcio com milho não interferiram no crescimento, produtividade de grãos e palhada do milho. Porém, não foram eficientes na supressão das plantas espontâneas.Escola de Agronomia - Universidade Federal de Goiás2016-08-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/41054Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 46, n. 3, Jul./Sep. 2016; 222-229Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 46, n. 3, jul./set. 2016; 222-229Pesquisa Agropecuária Tropical; v. 46, n. 3, jul./set. 2016; 222-2291983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/41054/21489Copyright (c) 2016 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessArantes, Ana Carolina CostaFontanetti, AnastáciaSoares, Marcio RobertoSilva Neto, Francisco José daPróspero, Alexandre Gonçalves2020-07-13T18:02:58Zoai:ojs.revistas.ufg.br:article/41054Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2020-07-13T18:02:58Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)false
